KENDRICK PREMIER HEATERS

Premier Brand heaters are the best heaters made and they produce considerably more heat than any other brand.

You don't always need the extra heat, but there are going to be times when you are glad to have it.

Our Premier Heaters are designed to be used with cameras and camera lenses, telescopes optics of all kinds, binoculars and temperature sensitive electronics.

Our Premier Heaters require the purchase of one of our Dew Controllers. Our systems are all 12 VDC with the exception of our #2021-A Digi_Klear Pad Heater which runs on 120 VAC.

We have heater systems for virtually any optic or electronic device used in amateur astronomy, outdoor photography and medical operating rooms. They are designed to keep electronic devices functioning and optics moisture free in humid and/or cold working environments.

The Premier Heater line is our flagship brand and our highest quality heater. They are built of the highest possible quality materials and the heaters are custom built to our electrical specifications. These are not off-the-shelf heaters! We use the best quality velcro, elastic and flex heaters available for this line. The cables are cold flexible down to temperatures of -40 and the cable housing is custom make for Kendrick to our specifications. All our competitors use cable that gets stiff and brittle in cold environments.

Our heaters have been built to use only as much power as necessary and thereby not waste energy. They have built in foam insulation on one side to help prevent heat loss in the atmosphere and direct the warmth generated by the heaters into the optics.

The table below will help you to determine which heater is the right one for you scope.

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.

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.

9.25-inch Dovetail bar (CGE)

Annals of the Deep Sky Vol 5 : A Survey of Galactic and Extragalactic Objects by Jeff Kanipe and Dennis Webb,

Volume 5 explores three very rich, and very different, constellations. Centaurus features a detailed overview of the Alpha Centauri system, descriptions of the Scorpius-Centaurus Association (the nearest OB affiliation to the Sun), and the stunning Omega Centauri globular cluster (NGC 5l39). Some time is also spent probing the many levels of the mysterious Centaurus A galaxy (NGC 5128), with its bizarre mixture of spiral and elliptical morphologies.

Cepheus may look dim to the unaided eye, but this constellation hosts some truly beautiful and beguiling objects. These include the star-forming region IC 1396 with its centerpiece, the Elephant Trunk Nebula (see cover image). We take a stroll down the Milky Way to visit several fine star clusters, some still associated with nebulosity, and other star-forming hotbeds.

Finally, Cetus leads us into a largely extragalactic realm where we find the nearby dwarf irregular IC l6l3, the edge-on spiral NGC 1055, and one of the brightest and nearest Seyfert 2 galaxies, M77. But the stars Mira and Tau Ceti are also on the itinerary, both of which have their stories to tell: one of a complex circumstellar environment, the other of possible extraterrestrial life.

We cannot visit these celestial marvels in our own hyperdrive spacecraft (yet), but Annals of the Deep Sky is the next best thing. Turn to page 1 and let it fly you across the universe.

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.

Dew is one of the many enemies of amateur astronomers. In a cold or humid environment, droplets and dew can form on the lens of telescopes and cameras, affecting both the quality of observation and photos.

Vespera’s anti-dew system will activate when a certain temperature and humidity threshold is reached. Heat generated continuously around the lens will remove the fog, creating better viewing conditions and sharper pictures.

It is ideal for people living in a humid region (sea, ocean, river, lakes, ponds, etc.) or in a region where temperatures are cold. The sensor is also great in winter when temperatures are close to 0° Celsius.

Anti-dew system

By equipping your station with this sensor, Vespera’s integral demister will activate when a certain temperature and humidity threshold is reached. Heat generated continuously around the lens will remove the dew, creating better viewing conditions and sharper pictures.

Improved focus

The condensation that produces dew or fogging affects the focus of Vespera’s photo sensor:

• Initialization and acquisition times may be longer because a larger number of photos will be rejected by our image processing algorithms, which check the quality of the images and discard them if they are not of sufficient quality.
• The sharpness of the pictures, which in astrophotography is mainly judged by the sharpness of the stars and the absence of any halo, is not as good.

The hygrometer and the associated demisting system will improve both your observation and your photos.

A discreet design

Measuring under 13mm, the hygrometer is equipped with an electronic board which is the smallest board our expert engineers have ever designed. The sensor fits discreetly into Vespera’s optical arm and is compatible with the use of filters. It will automatically turn the anti-fog system on and off, so you never have to worry about it.

Instructions for installation

The box comes with:

• the hygrometer and a screw ready to be fitted,
• a mini screwdriver.

Remove the standard Vespera lens ring and carefully insert the hygrometer into the notch above the lens. Screw the sensor in tightly using the screwdriver provided in the box. The sensor must not move in its housing.

To verify that the sensor is properly positioned, connect Vespera to your mobile device and launch the Singularity app. In the Space Center and then the Instrument screen, the ambient temperature and humidity are displayed.

Directions for use:

• Make sure Vespera is turned off before installing or removing the hygrometer.
• You do not need to remove the sensor on each use. We recommended leaving it in your Vespera to avoid any loss or damage.
• Activating the demisting system results in higher battery consumption. We recommend you charge your station before using it.

Dew also occurs during large temperature changes, for example in winter, when you move from a warm to a cold environment and the air inside your Vespera has remained warm. We therefore recommend that you take your Vespera outside for at least 30 minutes before starting any observations so that it can adjust to the ambient temperature.

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.

Low Read Noise, High Dynamic Range

The camera has a built-in HCG mode, which can effectively reduce readout noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain. When the gain is 252, the HCG mode is automatically turned on and the Dynamic range reaches a level close to 12bit.The readout noise is as low as 0.7e.

QE

Based on ZWO Laboratory calculations, the peak quantum efficiency of ASI585MC Air is 91%

Data source: This data is from ZWO Laboratory. The actual quantum efficiency peak value is subject to real-world data.

Cooling System

Thanks to the two-stage TEC cooling, ASI585MC Air can lower the CMOS sensor temperature to 30-35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
