The SkyWatcher Light Shroud for Truss Dobsonian 10 Inch is essential for every 10" Collapsible Dobsonian Telescope for high image contrast. It helps to prevent stray light and dew from entering the telescope setup and subsequently disrupting the telescope image. The shroud also serves as a care cloth that helps to block dust particles and impurities from entering the telescope.

TeleVue Barlows use multi-coated high index glasses for optimum aberration correction, exceptional contrast with virtually no light loss.Observed performance is aberration free, even when tested with f/4 scopes.

They even improve non TeleVue eyepieces and telescope performance.

Compromise image quality in any part of the optical chain and you've compromised every part!

TeleVue product design and execution deliver consumate satisfaction.

Every TeleVue Barlow must pass the same rigorous f/4, full field testing as all TeleVue eyepieces.

Offered in a 2x magnification, the Big Barlow is ideal for Newtonian scope owners.

It will be parfocal with both 2" and 1 1/4" eyepieces in this application.

Features include threads for 48mm filters, captive lock screw and full milti-coatings.

Note: The Tele Vue 2x BIG Barlow is not recommended for use with 2" diagonals because it's length prevents it from being parfocal. With some telescopes, focus might not be reached, particularly when the Panoptic interface lens is also used with it. A far better approach with no potential problems in any scope or with any eyepieces is to use the 2" 2x Powermate (PMT-2200), which essentially includes the Pan-Barlow Interface

The Tele Vue DeLite 11mm is a versatile medium focal length eyepiece. Generally eyepieces in the 9-15mm focal length range are excellent all-rounders. The DeLite 11mm could well be an ideal choice as your main high quality eyepiece.

Available in 18.2, 15, 11, 9, 7 and 5mm focal lengths, the DeLite series is a delightful addition to Tele Vue's visionary line of eyepiece developments. Named DeLite because that best describes the viewing experience, the name also recognizes designer Paul Dellechiaie's work.

ZWO ASI 174MM Astronomy Camera

ZWO's new ASI174MM camera uses Sony's latest Pregius IMX174 CMOS sensor. It combines several features putting it high on the list for anyone wanting to capture spectacular lunar and solar images, high resolution planetary images at long focal lengths or even as an autoguider without worrying "will I be able to find a guide star?"

The main advantages of the Sony IMX174 chip are:

• Large sensor size of more than 13mm across the diagonal
• High quantum efficiency of 78% at its peak
• Very low read noise of only 6e
• Extremely fast frame rate - effectively freezing moments of steady seeing
• Global shutter and no fixed pattern noise

Sony IMX174 Sensor - big benefits

Prior to the release of the ZWO ASI174 cameras it was difficult to find a good camera capable of full disk images of the Moon or Sun. This is no problem with the ASI174. It's sensor has a pixel array of 1936 x 1216 with 5.86 µm square pixels. This makes the diagonal measurement of the chip 13.4mm across.

The Image above shows the comparative field of view between the ASI120 camera and the new ASI174. Shot through a small refractor at 600mm focal length you can see the ASI174 will easily cover 0.5° of sky. It is now very easy to caputre full disk images of the Sun through many popular solar telescopes from Coronado and Lunt - no more mosaics required.

Quantum Efficiency and Read Noise

Another big benefit of Sony's IMX174 chip is the high quantum efficiency coupled with very low read noise. This equates directly to better signal to noise. Even with very fast capture rates you will get more signal from your target and less contribution from reading off the sensor of the camera - in essence cleaner data resulting in better images!

For a few years now Sony's highly regarded ICX618 CCD chip was a popular choice for planetary cameras. If we compare the new Sony IMX174 sensor to Sony's ICX618 the news is good for both QE and read noise.

The quantum efficiency of the IMX174 is slightly more than 11% better with read noise of nearly half! (6e for the IMX174 vs 11e for the ICX618).

Whether you're fine-tuning critical focus for deep sky imaging or just want fewer cables in the dark, the EAF Pro is a smart, streamlined upgrade for any astrophotography rig.

Celestron has reinvented the Tabletop Dobsonian telescope with StarSense Explorer—the first Tabletop Dobsonian that uses your smartphone to analyze the night sky and calculate its position in real-time. This 130mm aperture Celestron StarSense Explorer is ideal for beginners, thanks to the app's user-friendly interface and detailed tutorials. It's like having your own personal tour guide of the night sky.

Dock, Launch, Explore

Leave complicated star charts, imprecise planetarium apps, and computerized mounts behind. With StarSense Explorer, locating objects has never been easier, faster, or more accurate. Within minutes of setting up the telescope, you'll be navigating the sky with confidence. Simply place your phone in the unique StarSense dock and launch the StarSense Explorer app.

After aligning your phone to the telescope's optics (a quick and easy procedure), StarSense Explorer generates a list of celestial objects currently visible. Make your selection and arrows appear on-screen, guiding you as you move the telescope. When the object is ready to view in the eyepiece, the bullseye turns green. As you observe, listen to hundreds of audio descriptions and view detailed information about thousands of objects within the app’s robust database.

High-Quality Altazimuth Base

The stable Tabletop Dobsonian base provides a sturdy foundation for StarSense Explorer. The tabletop base is compact, lightweight, and easy to transport, making it perfect for travel. The base’s low-profile makes accessing the eyepiece easier for some observers (especially children). You can also place the base on a stable platform, like a table or hood of a car to raise it to a comfortable viewing height. Consider adding the optional tripod for even more viewing options.

Teflon bearings provide smooth motion in both altitude and azimuth. The integrated altitude "brake" system allows you to adjust the tension along the altitude axis to ensure the smoothest motion even with slight imbalances. As celestial objects appear to drift across the night sky, you'll be able to follow them easily.

The optical tube connects to the base via tube rings and a dovetail bar. It’s easy to adjust the tube’s position in the rings so the focuser is in the most ergonomic viewing position. The base features an eyepiece rack to keep your extra eyepiece(s) close at hand.

Dazzling Views with Excellent Optics

With a 130mm (5.1”) parabolic primary mirror, this telescope has enough light gathering ability to bring out detail in celestial objects. You can expect sharp, bright views of Jupiter’s four Galilean moons, its cloud bands and Great Red Spot, the rings of Saturn, the trapezium in the Orion Nebula, and the beautiful Pleiades Open Star Cluster. You'll be able to discern subtle details while viewing the Moon and planets, as well as faint galaxies and nebulae.

This telescope features a 1.25” rack-and-pinion focuser that accepts 1.25” eyepieces and dust covers for the front of the tube and the focuser.

Perfect for the City or Dark Sky Sites

Even if you live in a light-polluted city location, the Celestron StarSense Explorer 130mm Tabletop Dobsonian is advanced enough to easily pick out Jupiter, Saturn, open star clusters like the Pleiades, double stars like Acrux (the "tail" of the Southern Cross) the Orion Nebula, Omega Centauri, and more of the best and brightest celestial objects.

But if you can take the telescope to an even slightly darker location, more objects will become visible. With this 130mm Dobsonian and relatively dark skies, hundreds of fascinating objects are well within your reach.

The StarSense Explorer Tabletop Dobsonian is lightweight and equipped with carry handles, making it easy to transport to your observing site.

Smartphone Compatibility

Celestron StarSense Explorer works with most modern smartphones, including iPhone 6 and up, and most devices running Android 7.1.2 or later manufactured since 2016. For a complete compatibility list, click here.

Patented StarSense Sky Recognition Technology

StarSense Explorer uses patented technology and your smartphone to determine exactly where the telescope is pointed in the night sky. A Lost in Space Algorithm (LISA), like the ones satellites use in orbit to correctly orient themselves, helps the app match star patterns it detects overhead to its internal database.

While other astronomy apps may claim that they can help you find objects, they rely exclusively on the phone's gyros and accelerometers, which aren't as accurate as LISA technology. No other app can accurately tell you when your target is visible in the eyepiece.

The Bintel Superview Camera Projection eyepieces are one of the simplest ways to couple your DSLR to a telescope. The top section of the eyepiece unscrews allowing an M57 to M42 adapter to be fitted. The M42 T-thread can then allow the appropriate T-Ring to be attached and thus adapts to your DSLR camera.

Review

This is a very good low power/wide field eyepiece. With 43 degree apparent field it provides the widest field possible from a 1.25” eyepiece. It's ideal for large open clusters, emission and reflection nebulae, large and faint nebula remnants such as the Vela Supernova Remnant and galaxy clusters.

The rubber grip gives sure grip and makes it comfortable to use in cold weather.. Better suited to the longer focal ratios of refractors, Schmidt-Cassegrains, and Maksutov-Cassegrains than it is to reflectors with focal ratios shorter than f/6.

In scopes that are longer than f/6, it will give you the widest and brightest field possible from a 1.25” focuser telescope.

The 28mm of eye relief makes it a good choice for eyeglasses wearers. It' s parfocal with the shorter focal length Plossls. Filter threads to fit your filters and blackened lens edges.

The Celestron Dew Heater Ring is the ideal dew prevention solution for your Celestron telescope. This must-have accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts to your 6" Celestron Schmidt-Cassegrain optical tube, replacing your retaining ring, so you'll never be caught without it. The installation process is quick and easy (follow the manual for instructions).

How it works

The Dew Heater Ring replaces the plastic retaining ring on your Schmidt corrector lens for efficient heating across the lens. The ring is constructed of lightweight, durable aluminum. Its rigid frame supports the cable circuity and the telescope's Schmidt corrector lens. Unlike other heating bands or strips that inefficiently heat the lens cell to warm the glass, the Celestron Dew Heater Ring heats the corrector glass directly, providing the most efficient transfer of heat to prevent dew formation.

Simply plug the ring into an external 12V DC power source for consistent, continuous heat that will prevent dew from forming even under heavy dew conditions. The Dew Heater Ring features two storage clips to keep the power and thermistor jacks secure when not in use while accommodating the telescope's dust cover.

The Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell. Corral the power and thermistor jack to prevent them from dangling and reduce unwanted pulls on the cable connection to the rings.

The Dew Heater Ring comes complete with:

• Dew Heater Ring
• Cable management clip
• Power jack extension cable
• Paper installation shield

Enhance your setup

To achieve the highest level of dew prevention while maximizing power efficiency, we strongly recommend pairing the Dew Heater Ring with a Smart DewHeater Controller (sold separately). The controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring’s power draw, greatly increasing battery life. The ring also includes an extension cable for connecting the ring directly to one of the controllers’ heater output ports, or to a third-party controller’s heater output port. (Note: the ring’s integrated thermistor is only compatible with the Celestron Smart DewHeater Controllers).

We also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power the Dew Heater Ring needs to keep the optics clear.

The Bintel SCT Diagonal Adapter can be used to change a Bintel 2 inch Diagonal from Slip fit to SCT Thread fit.

Made up of three component parts, it can also be used as a short SCT Prime Focus adapter by removing the ring at the top which is T Threaded.

Tele Vue's Delos 14mm is a medium focal length eyepiece that creates an “immersive viewing experience”. With its generous 20mm eye-relief and wide 72° apparent field of view you will be hard pressed to find another eyepiece that is such a pleasure to look through. Amazing wide fields of view in well corrected refractors with short to medium focal lengths (over 1° FOV up to 1000mm focal length). While some of the shorter focal length Delos eyepieces may provide too much power in long focal length Cassegrains, the Delos 14mm is suitable for any focal length telescope.

There is a good chance the TeleVue Delos will be seen as the ultimate combination of performance, viewing comfort and price. If you've been keeping a spot in your case for an affordable, premium eyepiece, you should consider a Delos - you won't be disappointed! Lessons learned from the tremendously successful Ethos series were applied to develop this long eye-relief, 72° apparent field of view eyepiece line.

The Delos 14mm has standard a 1.25" barrel making it suitable for almost any telescope or even bino-viewers!

Tele Vue Delos 14mm - Specifications

• Model # EDL-14.0
• Focal Length 14mm
• Barrel Size 1.25"
• Apparent Field of View 72°
• Eye Relief 20mm
• Weight 408g
• Field Stop 17.3mm

Background:

In 2011 Tele Vue introduced the Delos, mid-to-short focal length line of 20mm eye-relief, 72° apparent field of view eyepieces. Every optical, mechanical, and ergonomic aspect was rethought to achieve reference-standard performance for any visual application.

The Delos was conceived as a narrower field Ethos. Reducing the field to 72° allowed freedom to increase eye-relief, while controlling pupil aberrations, all without making the eyepiece too large. With Ethos performance standards as benchmarks, the Delos design achieves full field sharpness, virtually perfect f θ (theta) distortion mapping, and color neutrality. Image fidelity is maximized utilizing glass matched multicoatings and anti-reflection surfaces throughout the eyepiece.

Contrast is further enhanced with a new, continuously adjustable height eyeguard system that can be locked in any position. Since the Delos eye-lens measures a quite large 35mm in diameter, preventing stray light from reflecting off the first surface and extraneous light from entering your eye pays off in a nice increase in perceived contrast. The eyeguard's sliding action allows for positioning the soft rubber eyeguard at the ideal height to suit the observer's preference. Indicator marks on the eyepiece body are handy reference guides for setting your perfect position. The eye-guard can also rotate for Dioptrx users.

Review of the 6mm & 10mm Delos from Astronomy Magazine, December 2011

Excerpts from Sky & Telescope, June 2011, review of Delos eyepieces:

WHAT WE LIKE:

Essentially perfect optics
"Immersive" observation experience

WHAT WE DON'T LIKE:

I spent several nights viewing the Moon, Saturn, stars and nebulae with a variety of telescopes … .

The Delos eyepieces are "easy to look through … . They have flat fields, delivering absolute pinpoint stars from edge to edge with no hint of color aberration. The view, especially during the daytime, is very pure with no noticeable color tint. And there wasn't a hint of ghosts or reflections, even with the brightest stars".

"What caught me a bit off guard, however, was something that's best described as the observing experience. It was distinctly pleasurable."

"I have the sensation of looking out of a circular window rather than into an eyepiece."

Enjoy the most dazzling views of nebulae with your Celestron Origin when you add this H-alpha H-beta OIII (Hα-Hβ-OIII) imaging filter. This specialized filter allows high throughput of light wavelengths in emission nebulae while blocking other wavelengths that could diminish image quality and detail. The result is bright, colorful nebulae images that “pop” with detail against the black sky background.

How does the Nebula Filter for Origin work? Emission nebulae primarily emit at discrete wavelengths of light—Hα at 656nm, Hβ at 486nm, and OIII at 496/501nm. By strategically transmitting only these wavelengths of light and blocking the rest of the spectrum, the filter dramatically reduces the effect of light pollution. The “bad” light is blocked while the “good” light associated with emission nebulae passes through to Origin’s sensor.

You’ll immediately notice much higher contrast in your images, especially from your light-polluted backyard! And since the transmission at the critical wavelengths is so high, the nebula will not be dimmed—only the background will be blacker. You’ll also notice some contrast improvement in images of nebulae from darker skies, as the filter serves well in blocking natural skyglow.

Nebula Hunting

The Nebula Filter is perfect for imaging emission nebulae like the North America Nebula (NGC 7000), Lagoon Nebula (M8), Orion Nebula (M42), the Carina Nebula (NGC 3372), and dozens more. The imaging filter offers maximum light transmission in the key Hα-Hβ-OIII wavelengths, producing high contrast for emission nebulae like these.

The transmission spectrum for the Nebula Filter is 85% or greater at key wavelengths (486nm, 496nm/501nm, 656nm) and less than 0.5% transmission elsewhere. As a narrowband filter, it blocks much of the visible spectrum and only lets these specific wavelengths through. Because of this, you should not use this filter while observing or imaging broadband emission objects, such as galaxies and star clusters. For those objects, you’ll achieve the best results by removing the nebula filter and reinstalling Origin’s clear optical window.

Other similar imaging filters on the market have much narrower bandpasses at the critical Hα-Hβ-OIII wavelengths. Unfortunately, these filters block much of the incoming Hα-Hβ-OIII light for an f/2.2 optical system like Origin’s 6” RASA. This is because a RASA brings light into the filter at a steeper angle, which causes a spectral shift. If you use filters not explicitly designed for use at f/2.2, some of the light from the nebula will be blocked, resulting in a dimmer image. The Nebula Filter for Origin was custom-engineered to work at f/2.2, so none of the “good” light from the nebula is inadvertently blocked by the filter.

Body and Storage

The filter features a machined aluminum black anodized cell with a knurled rim for easy grip during installation. We’ve added anti-reflection coatings to help suppress reflections on the glass. The filter fits directly into the filter drawer in the Celestron Origin’s front lens cell, where the optical window sits. Simply remove the clear window and replace it with the filter. Origin maintains its optical performance across the entire system with the filter installed. No other adapter is needed.

Each filter comes with a foam-lined plastic storage case to safely store the filter or the optical window glass that came with your Celestron Origin when not in use.

Celestron tests every Nebula Filter for Origin individually to verify its performance. Along with your filter, you will receive a spectral transmission graph (like the one pictured above) showing the results of your filter’s test and verifying it performs as expected throughout the spectrum.

The field area of this new eyepiece is more than 50% larger than an 82° field. The Tele Vue Ethos 17mm is essentially multiple eyepieces, delivering the true field size of a longer focal length, narrower apparent field eyepiece with the benefits of higher power and darker sky background.

We invited NEAF attendees to take a look and see the universe the way we think it was meant to be experienced, with a field of view incredibly wide and sharp! We were very pleased indeed by the response and validation of our design goals.

The Tele Vue ETHOS 17mm is an ideal complement to the 31mm Nagler Type-5. They are parfocal (both have focus locations about 10mm above shoulder) and the 31mm Nagler Type-5 has exactly twice the true field area.

Tele Vue's Delos 12mm is a medium focal length eyepiece that creates an "immersive viewing experience". With its generous 20mm eye-relief and wide 72° apparent field of view you will be hard pressed to find another eyepiece that is such a pleasure to look through. Amazing wide fields of view in well corrected refractors with short to medium focal lengths (over 1° FOV up to 800mm focal length). While some of the shorter focal length Delos eyepieces may provide too much power in long focal length Cassegrains, the Delos 12mm is suitable for any focal length telescope.

There is a good chance the TeleVue Delos will be seen as the ultimate combination of performance, viewing comfort and price. If you've been keeping a spot in your case for an affordable, premium eyepiece, you should consider a Delos - you won't be disappointed! Lessons learned from the tremendously successful Ethos series were applied to develop this long eye-relief, 72° apparent field of view eyepiece line.

The Delos 12mm has a 1.25" barrel making it suitable for almost any telescope or even bino-viewers!

Tele Vue Delos 12mm - Specifications

• Model # EDL-12.0
• Focal Length 12mm
• Barrel Size 1.25"
• Apparent Field of View 72°
• Eye Relief 20mm
• Weight 408g
• Field Stop 15.0mm

Background:

In 2011 Tele Vue introduced the Delos, mid-to-short focal length line of 20mm eye-relief, 72° apparent field of view eyepieces. Every optical, mechanical, and ergonomic aspect was rethought to achieve reference-standard performance for any visual application.

The Delos was conceived as a narrower field Ethos. Reducing the field to 72° allowed freedom to increase eye-relief, while controlling pupil aberrations, all without making the eyepiece too large. With Ethos performance standards as benchmarks, the Delos design achieves full field sharpness, virtually perfect f θ (theta) distortion mapping, and color neutrality. Image fidelity is maximized utilizing glass matched multicoatings and anti-reflection surfaces throughout the eyepiece.

Contrast is further enhanced with a new, continuously adjustable height eyeguard system that can be locked in any position. Since the Delos eye-lens measures a quite large 35mm in diameter, preventing stray light from reflecting off the first surface and extraneous light from entering your eye pays off in a nice increase in perceived contrast. The eyeguard's sliding action allows for positioning the soft rubber eyeguard at the ideal height to suit the observer's preference. Indicator marks on the eyepiece body are handy reference guides for setting your perfect position. The eye-guard can also rotate for Dioptrx users.

Review of the 6mm & 10mm Delos from Astronomy Magazine, December 2011

Excerpts from Sky & Telescope, June 2011, review of Delos eyepieces:

WHAT WE LIKE:

Essentially perfect optics
"Immersive" observation experience

WHAT WE DON'T LIKE:

I spent several nights viewing the Moon, Saturn, stars and nebulae with a variety of telescopes … .

The Delos eyepieces are "easy to look through … . They have flat fields, delivering absolute pinpoint stars from edge to edge with no hint of color aberration. The view, especially during the daytime, is very pure with no noticeable color tint. And there wasn't a hint of ghosts or reflections, even with the brightest stars".

"What caught me a bit off guard, however, was something that's best described as the observing experience. It was distinctly pleasurable."

"I have the sensation of looking out of a circular window rather than into an eyepiece."

— di Cicco, Dennis. "Tele Vue's New Delos Eyepieces". Sky & Telescope (June 2011). p. 58, 59.

Tele Vue's Delos 8mm is a short to mid focal length eyepiece that will deliver useful magnification in almost any telescope. With a generous 20mm eye-relief and wide 72° apparent field of view the views will astound. Wide fields of view in telescopes with short to medium focal lengths (almost 1° in 600mm focal length telescopes). Mid to high powered views without the need for a Barlows or Powermate in Cassegrain telescopes! The Delos 8mm would be a worth investment for just about any telescope

Tele Vue Ethos 8mm

The Tele Vue Ethos 8mm was first demonstrated at NEAF in 2008. In addition to matching all the key performance criteria of its 13mm sibling, the new 8mm version is parfocal in 1¼" focusers with Radians, Plössls, Type 6 Naglers and 1¼" Panoptics.

Its lighter weight and smaller diameter than the 13mm Ethos makes the 8mm suitable for anyone using a binocular viewer. A perfect eyepiece for terrestrial viewing with a short refractor. Comparing an 8mm Ethos to an 8–24mm Zoom eyepiece, the 8mm Ethos has the power of the 8mm Zoom and 83% of the field of the 24mm setting!

Tele Vue is still the leader in high performance, wide angle eyepieces for astronomy. There will always be cheap imitators, but astronomers the world over agree Tele Vue eyepieces are simply the best. One look is all it takes...come and see for yourself!

Tele Vue is known for its in-house eyepiece and telescope designs by Al Nagler; the development of the Ethos series brought new meaning to the term "in-house." The concept for this eyepiece series was proposed by Tele Vue President David Nagler, with performance parameters giving it the fundamental characteristics (the ethos) of a Tele Vue eyepiece: high contrast, comfortable eye relief and full field sharpness. Control of astigmatism, field curvature, lateral colour, angular magnification distortion correction, and low pupil sensitivity for daytime use were specified criteria.

Following Tele Vue's philosophy of pushing the state of the art, long-time Tele Vue employee and optical design protégé Paul Dellechiaie took up the challenge and designed the basic eyepiece form. Under Al's guidance, Paul tweaked his design to fulfill the original goals.

While sharpness is inherent to the optical design, contrast is maximized through the intelligent use of flat finished baffles and ultra low reflectance, high efficiency coatings tuned to the composition of each element.

Introduced at the 2007 Northeast Astronomy Forum, Tele Vue once again broadened the amateur astronomer's perspective on the universe with: 100° of pure Tele Vue quality. The field area of this new eyepiece is more than 50% larger than an 82° field. The Tele Vue Ethos is essentially multiple eyepieces, delivering the true field size of a longer focal length, narrower apparent field eyepiece with the benefits of higher power and darker sky background.
