Farpoint Laser Collimator 650nm (1.25 inch )

All Farpoint laser collimators have a LIFE TIME Alignment Guarantee. We will realign any Farpoint laser collimator for free! But Farpoint lasers keep their factory alignment. This is due to our robust laser body and (most importantly) our unique alignment screw design explained below.

Farpoint lasers have EIGHT alignment screws instead of six, four, or even three as in some other lasers. Instead of a staggered arrangement (top hole, bottom hole, top hole) that can allow the diode to move, BOTH ends of the laser diode are held in place by two sets of directly opposing screws for precise and lasting alignment. Again, only Farpoint lasers have this superior alignment screw arrangement with four DIRECTLY OPPOSING screws aligning the top of the laser diode and another four DIRECTLY OPPOSING screws aligning the bottom of the laser diode.

Farpoint laser bodies are precisely machined from a single piece of aluminum in a single machining step, resulting in perfect alignment.

Farpoint lasers have a small aperture (0.76mm or 30/1000 of an inch) for less speckling and more precise reading of the laser beam’s position on the telescope mirror. Farpoint has the smallest aperture of any laser in the amateur astronomy market.

TMB PlanetView Planetary Eyepieces:

The TMB PlanetView Planetary Eyepiece series is designed for high-magnification planetary and lunar observing, delivering sharp, high-contrast views with excellent eye comfort. Choosing the right focal length for your telescope typically provides a significant upgrade in magnification and fine detail compared to the stock eyepieces supplied with most telescopes, making planetary features clearer and easier to observe. Featuring a 5-element optical design and a wide 58° apparent field of view, these eyepieces offer a more immersive experience than traditional narrow-field planetary designs while maintaining the crisp detail needed for serious observing.

Fully multi-coated optics and internal baffling maximise light transmission and suppress stray reflections, improving contrast on subtle planetary features and fine lunar detail. The large eye lens and generous eye relief make these eyepieces comfortable to use, especially during long observing sessions or when wearing glasses.

Built with an all-metal housing and a fold-down rubber eyecup, TMB PlanetView eyepieces are robust, practical, and compatible with all standard 1.25" focusers and filters. They are also Bintel’s number one recommended first upgrade for most telescopes, offering one of the simplest and most noticeable improvements you can make to planetary and lunar performance.

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.

Suggested Controller

Users will experience incredible views without breaking the bank or impinging on your telescope's balance. They represent what is perhaps the best buy today for astronomers on a budget or for beginners. But don't be fooled by their low prices - these might well turn out to be all the eyepieces you will ever need!

The Bintel Plossls are available in a 1.25" barrel size and 9 different focal lengths ranging from 6mm to 40mm. The 4mm, 6mm and 9mm models are great for high power planetary and lunar observation. The 12mm and 15mm are perfect intermediate focal lengths, performing well on both deep-sky and planetary subjects. The 20mm and 25mm models would be excellent choices for low power scanning of open star clusters and viewing larger galaxies. The 32mm and 40mm models offer a wide field and are superb for wide field scanning, detailed observations of large diffuse subjects or as a finder eyepiece.

• All eyepieces are fully multicoated (FMC) for maximum light transmission
• High quality lenses provide the best-possible sharpness all over the field of view
• Blackened lens edges reduce light scattering and improve contrast
• Fold-down rubber eyecups to keep out stray light
• Comfortable eye relief at all but the shortest focal lengths (As in all Plossl eyepieces, eye relief can get tight at the shorter focal lengths but this is design constraint, not a fault of these eyepieces)
• Includes two end caps
• 50 Apparent field (degrees)

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:

Specs

Take the guesswork out of using third-party heating bands or straps and increase your power efficiency with the Celestron Thermistor for Smart DewHeater Controllers. This accessory allows the Smart DewHeater Controller (sold separately) to deliver just the right amount warmth for to your telescope’s corrector to prevent dew without wasting battery. 6’ cable length accommodates a wide variety of configurations.

How it works

Connect the heating band to your telescope and place the Thermistor's sealed probe tip under the heating band. Plug each cable into its corresponding port of the Smart DewHeater Controller.

NOTE: This thermistor is not required if you are using a Celestron Dew Heater Ring because the ring already contains a built-in thermistor.

NOTE: Heating Band Not included.

Enhance your setup

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

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.

But don't be fooled by their low prices - these might well turn out to be all the eyepieces you will ever need!

The Bintel Plossls are available in a 1.25" barrel size and 9 different focal lengths ranging from 6mm to 40mm. The 4mm, 6mm and 9mm models are great for high power planetary and lunar observation. The 12mm and 15mm are perfect intermediate focal lengths, performing well on both deep-sky and planetary subjects. The 20mm and 25mm models would be excellent choices for low power scanning of open star clusters and viewing larger galaxies. The 32mm and 40mm models offer a wide field and are superb for wide field scanning, detailed observations of large diffuse subjects or as a finder eyepiece.

• All eyepieces are fully multicoated (FMC) for maximum light transmission
• High quality lenses provide the best-possible sharpness all over the field of view
• Blackened lens edges reduce light scattering and improve contrast
• Fold-down rubber eyecups to keep out stray light
• Comfortable eye relief at all but the shortest focal lengths (As in all Plossl eyepieces, eye relief can get tight at the shorter focal lengths but this is design constraint, not a fault of these eyepieces)
• Includes two end caps
• 50 Apparent field (degrees)
