Annals of the Deep Sky is a comprehensive reference that guides amateur and semipro astronomers into every mind-boggling corner of the observational universe. Each volume presents extensive descriptions of prominent stars and deep-sky objects. No other popular work in astronomy provides the comprehensive historical background and astrophysical appraisals of prominent stars and celestial objects.

In Volume 11, we delve into the celestial smorgasbord found in the constellations Gemini, Grus, Hercules, Horologium, and Hydra. Featured objects include the open cluster M35 in Gemini, as well as the strange case of NGC 2371-72, one of the most unusual examples of a planetary nebula. The southern constellation Grus contains IC 5148, a large planetary nebula with an unusual inner-tube-like morphology, as well as the grand design, multi-armed spiral galaxy NGC 7424, which contains a number of enigmatic radio and X-ray sources. Hercules hosts the great globular clusters M13 and M92, of course, and imagers will want to target Abell 2151, the rich Hercules Cluster that links up with the Great Wall of galaxies. Horologium contains the remarkable star Gliese 1061, a solar neighbour harbouring a planetary system. And don’t forget to check out the globular cluster NGC 1261 and the stunning Seyfert galaxy NGC 1433. Finally, Hydra’s showcase object is the Southern Pinwheel Galaxy, M83; other attractions include the face-on multiarm spiral galaxy NGC 2835 and the spectacular pair NGC 3314A and B — two entwined galaxies with different orientations.

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 11" Celestron Schmidt-Cassegrain (manufactured 2006 or later), EdgeHD, and RASA 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.

To achieve the best astroimages, it is important to attain the proper back-focus distance for your camera relative to the telescope it is being used with. If the back-focus distance your camera consumes is not exact, the performance at the corners of full frame imaging sensors will suffer—stars will appear elongated and not as pinpoints.
Example: RASA 8 with a ZWO ASI 183 MC PRO camera

• Required back-focus distance for RASA 8 with included M42 camera adapter: 25mm
• Back-focus consumed by ZWO ASI 183 MC PRO camera: 17.5mm
• To achieve equal back-focus distance, a 7.5mm M42 spacer ring is required

Celestron’s M42 Spacer Ring kit includes three different length spacer rings to achieve the proper back-focus distance with our popular Celestron optical tubes and T-thread camera adapters.

How to Use
Depending your method of astrophotography (DSLR or CCD/CMOS), there are two ways to use the M42 Spacer Ring. If you are using a DSLR, place the desired M42 Spacer Ring between your T-Ring and your T-Adapter for your optical tube. If you are using a CCD or CMOS camera, place the desired M42 Spacer Ring between the camera and the T-Adapter for your optical tube.

Below is a quick guide to help you determine which spacer ring to use for our EdgeHD, Schmidt-Cassegrain, and RASA 8 optical tubes:

High quality, value for money telescope eyepieces optimised for planetary and close up viewing of deep sky objects.

What sets the Bintel Premium Long Eye Relief range apart from just every other mid-priced short to medium length eyepiece is their remarkably flat field design, edge-to-edge sharpness and superb mechanical construction.

You’ll notice the difference in crispness when exploring the details on the surface of the Moon, gazing at the rings of Saturn or peering into the heart of a globular like Omega Centauri. Views will be razor sharp all the way out to the edge of their 55 degree field of view thanks to a modern multi-element design.

The 14.5mm focal length of this eyepiece makes it great for medium magnification views.

Over 20mm of eye relief – the distance you can observe back from the eyepiece and still take in the entire field of view – makes for comfortable viewing with or without eye glasses.

The Bintel Premium Long Eye Relief Eyepieces are the perfect first upgrade from the standard eyepieces that come with your telescope.

With the ZEISS SFL 8x40 binoculars (SmartFocus Lightweight), special moments can be experienced with ease. Optimized to be as lightweight and compact as possible, the SFL binoculars are a perfect addition to the SF family. The new Ultra-High-Definition (UHD) Concept ensures true-to-life color reproduction and the highest level of detail. Thanks to its SmartFocus Concept, the focus wheel is perfectly positioned and enables fast and precise focusing – even with gloves on. The optimized ergonomics and a large exit pupil allow for a relaxed and undisturbed viewing experience.

With a field of view of up to 140 meters at a distance of 1,000 meters and a closest focusing distance of 1.5 meters, the SFL 8x40 deliver a perfect overview combined with precise detail recognition.

The lens diameter has been reduced by 2 mm, making it possible to use thinner lens elements at closer spacing and thus reduce the binoculars’ weight by up to 20% and their volume by up to 13% compared to the ZEISS Victory SF models. As a result, the SFL binoculars are up to 30% lighter than comparable products from competitors.

The Bintel Package

All Nikon Monarch Fieldscope purchases from Bintel include both the scope body and eyepiece, but additionally a carry strap and stay-on-case.

The 55mm focal length has the largest true field possible for 2" eyepiece holders -3 times the true field area of any 1¼" eyepiece. The focal plane is placed at the end of the barrel to minimize vignetting. Performance with Schmidt-Cassegrains is remarkable since it avoids the image degradation and severe vignetting which occurs when using telecompressors. Long eye-relief and unique adjustable eyeguard for eyeglass wearers.

Review

A must for deep sky fans. This good low power/wide field eyepiece has the largest true field and largest exit pupil possible for 2" eyepiece holders-3 times the field area of any 1 l/4" eyepiece.

Performance with Schmidt Cassegrains is remarkable since it avoids the image degradations and severe vignetting which occurs when using tele compressors.

The long eye relief and unique adjustable eye guard allows eyeglass wearers to see the full field of view even with their glasses on.

The rubber grip gives sure grip and makes it comfortable to use in cold weather.

Tele Vue's Delos 17.3mm is the longest focal length in the Delos series. Still with a generous 20mm eye-relief and wide 72° apparent field of view you will enjoy an emmersive viewing experience that is hard to match. The optimized combination of field size and eye-relief makes Delos an eyeglass wearers dream!

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 17.3mm - it won't disappoint! 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 17.3mm has a standard 1.25" barrel making it suitable for almost any telescope. An excellent choice for low power viewing in bino-viewers!

Tele Vue Delos 17.3mm - Specifications

• Model # EDL-17.3
• Focal Length 17.3mm
• Barrel Size 1.25"
• Apparent Field of View 72°
• Eye Relief 20mm
• Weight 408g
• Field Stop 21.2mm

Background

Tele Vue introduced the Delos In 2011. The series includes mid-to-short focal lengths with all providing 20mm eye-relief and 72° apparent field of view. Tele Vue designer Paul Dellechiaie rethought every optical, mechanical, and ergonomic aspect to achieve reference-standard performance for any visual application.

The Delos was conceived as a narrower field Ethos. Eye-relief was increased while still controlling pupil aberrations by reducing the field to 72°. This was achieved 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 colour 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.

Delos Eyepieces Reviews

Quotes from review of 10mm, 4.5mm, & 14mm Delos on Alpha Lyrae website.

• The stunningly flat field and lack of optical aberrations really allow clusters to shine and galaxies and nebulae are resplendent.
• It is rare I use any other eyepiece for deep sky observing anymore.

• Quite simply, the planetary performance matches the very best dedicated planetary eyepieces I have ever used such as the TMB Super Monocentric.
• There is also an indescribable quality which makes them a very easy and relaxing eyepiece to use.

Excerpt from Delos 17.3mm review in Astronomy Now magazine.

Examining the stars of the Pleiades served up by the 17.3mm Delos, I was immediately struck by the pinpoint star images right to the edge of the field-of-view. Contrast was superb. Nor could I detect any signs of off-axis distortions.

More Than Expected (Delos 6- and 10-mm)

And while the 20 mm of eye relief make them attractive for those who observe wearing eyeglasses, it was the "distinctly pleasurable" observing experience that most impressed our reviewer. When it comes to eyepiece design, The Delos seems to have hit all the sweet spots.

Excerpt from ATT review of Delos 6- & 10-mm eyepieces:

Wide-Field Eyepieces That Pack a Planetary Punch

With the Delos, the eyepiece simply "disappears" and allows the observer to observe. I could find nothing whatsoever to complain about; the "twist and tighten" eye relief adjustment feature is the best I've ever seen in any eyepiece, and the optics are essentially perfect. Tele Vue somehow always finds a way to continuously improve upon their eyepieces and the Delos is certainly no exception. Bottomline: If you're in the market for a planetary eyepiece, you owe it to yourself to consider the Tele Vue Delos.

— Erik Wilcox. "Tele Vue Delos". Astronomy Technology Today (Nov-Dec 2011). Full Review.

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

• Contrast was excellent - right up there with some of the best planetary eyepieces I've ever used.
• I searched but saw no internal reflections or scattering in either eyepiece.
• The flat field the Delos eyepieces produce really made star fields pop. Open clusters epitomized the old standard "diamonds on velvet". Stars on and off axis showed no sign of astigmatism.
• Tele Vue has constructed an eyepiece that stands with the best deep-sky and planetary eyepieces on the market.

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

WHAT WE LIKE:

Essentially perfect optics
"Immersive" observation experience

WHAT WE DON'T LIKE:

Trying to nail down why the observing experience is so pleasurable.

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.

If you are already using a computer in your observatory for other reasons, this provides a way for you to focus your telescope without fumbling around in the dark for the focuser handcontroller. It works best with 5V focus motors such as the newer style JMI Motofocus, but can also work with 9V or 12V motors. Motors requiring up to 100mA of current will work with the FCUSB. To date, the FCUSB has been tested with the JMI Motofocus, Moonlite DC motorized focusers, Orion AccuFocus, Meade 1209, Televue Focusmate Driver, and WalterLee heliFocus. The FCUSB also eliminates the need for a battery to run your focuser, since the motor is now powered directly from the USB port of your computer. Using the free FocusPal software, you can control the speed and direction of your motor with just mouse clicks! For further information, please read through the FCUSB User Manual Third-party software that supports the ASCOM Focuser standard will also work with the FCUSB using the FCUSB ASCOM driver. DC focus motors don't provide absolute positioning repeatability like a stepper motor does, but we have tried the FCUSB with third-party autofocusing software and obtained decent results.

An excellent premium quality low power wide field eyepiece. It is ideal for observing large emission and reflection nebulae, Supernova Remnants and large open star clusters. 

It is well-suited for any telescope with a focal ratio of f/5 or longer offering 7mm exit pupil at f/5. Works wonderfully in SCT's for large field of view. 

It has a huge 28mm of eye relief and can be used by eyeglass wearers with no vignetting of the field. This is a lot of eyepiece so its heavy weight may cause some minor concern in Dobsonians.

Tele Vue Ethos 10mm Specifications

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.

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.
