Directly-Coupled Configurations for 2" Eyepieces
The ideal way to use the MPCC for visual use with 2" eyepieces is to directly couple it to the eyepiece, via the eyepiece's 2" (48mm) filter threads. This allows the MPCC to be accurately positioned, providing the optimum spacing for top performance and taking the guesswork and error out of setting a continuously variable holder. The rigid coupling also eliminates the possibility of sag or tilt from variable holders, particularly with the largest and heaviest eyepieces. This configuration also enables the MPCC to work without needing any additional back-focus. In this configuration, the eyepiece will actually come to focus about 10mm further OUT than it does without the MPCC. Since most large Dobs are limited in their back-focus, this may be the only way to achieve coma correction with some eyepieces (short of trimming truss poles..). Dob users will also appreciate the light weight of the MPCC system, which avoids the balance problems of heavier correctors.
Here are examples of direct-coupling the MPCC to some popular wide field 2" eyepieces
For best performance, the corrector should be positioned approximately 55mm from the rear mounting face of the MPCC housing to the eyepiece's field stop (+/- 3mm for best on-axis sharpness). In order to attach and properly locate the MPCC, only 1-3 inexpensive adapters are required. We also offer a convenient spacer set, that will give you the spacers needed to fit the majority of 2" eyepieces. Please see the Spacer Tube and Adapter section, below, for a listing of available spacers.
OPTIONAL:
Configurations for 1.25" Eyepieces
To use the MPCC with 1.25" eyepieces, the only additional parts required are the T2-15 Reducer/Eyepiece Holder and one or two spacer rings. The result is a compact and lightweight coma-correcting assembly that slips completely within a

This Astro-Tech 20mm Titan is a very wide 70 degree field medium power 1.25" eyepiece at a very economical price. The calculator below will let you see just how wide the field will be with your particular scope. For example, it will give you a wide 1.23 degree field and a bright 4.4mm exit pupil at 57x with a 10" f/4.5 Dobsonian. This will give you almost five minutes to observe an object as it drifts from one side of the eyepiece's flat field to the other in such a scope. That's plenty of time for multiple observers to look at the object or for you to absorb as much detail as possible before having to reposition the scope. With short focal length refractors, the 20mm Titan is a low power, very wide field eyepiece. With the 400mm focal length Astro-Tech AT-66, for example, it provides 20x, a 3.3mm exit pupil, and a huge 3.5 degree field of view that's seven times as wide as the Moon.
While it's particularly well-suited for use with Dobsonian scopes and short focal length refractors, it can provide "picture window onto space" images with any telescope type. Even medium and long focal length telescopes provide impressive views. Use this 20mm Titan on an 8" f/10 catadioptric scope and you still get a 0.7 degree field at 100x, perfect for the Moon and globular clusters like M9, M13, and M22. The low price of this eyepiece also makes it a very affordable choice to buy in pairs for binoviewer. Its 11mm eye relief is quite reasonable for this focal length, although it can somewhat limit the field for eyeglass wearers. Since the Astro-Tech field is substantially wider to begin with than most other eyepieces in this price range, most eyeglass wearers won't find the minor vignetting to be a drawback. Those who don't wear glasses will see a huge field at only a fraction the cost of many more exotic wide field eyepiece designs.
The Vixen Polarie Polar Scope is a dedicated polar finder for the Vixen Polarie Camera Tracker. This Vixen Polar Scope will make your experience with the Polarie far easier and will reduce your set up time to just a few minutes.

AstroZap Baader Solar Filter For 11" SCT and 306mm-316mm Telescopes AZ1007
Baader AstroSolar is unlike any other solar filter on the market! The sun appears in neutral white when using AstroSolar providing and exceptional observing experience. Other films and some glass filters produce blurry reddish or bluish Solar images which in turn cuts part of the spectrum. Faculae regions, which are visible mostly in the blue wing of the spectrum, are very hard to see with an orange sun. Because of the neutral color balance of AstroSolar, you can use various color (or interference) filters. This allows observers to focus on certain spectral passbands for investigations of different layers within the solar "atmosphere".
The uniqueness of Baader AstroSolar is not only in its ability to observe the sun using one of the best filters out there but also because of the dedication in making it one of the safest filters around. All processes in correlation to this product have been carefully tested and coatings are continuously inspected for consistency to ensure your eye safety. Further more, the National Bureau of Standards in Germany, the PTB has approved Baader AstroSolar for eye safety.
AstroSolar is essentially free from pinholes. Because of the coating on both sides, the probability of two pinholes overlapping each other is tremendously faint. There can be a time when pinholes do appear but to 1 out of 1000 only in optical density 2.5! Baader AstroSolar film Filter cell is constructed of lightweight 18Ga. aluminum and powder coated white. To ensure a secure fit, the Filter cell has heavy duty threaded inserts and nylon thumbscrews.

The VF Prime PRO is the evolution of the original VF Prime DSLR Viewfinder. The Prime PRO now includes a camera baseplate which after mounted, allows you to mount the viewfinder right up to the LCD of the camera. NO longer do you need to put a semi-permanent stick-on frame onto your camera. Most DSLR LCD screens are small so trying to hold the camera in front of you while pulling focus and framing a shot can lead to shaky footage. If you happen to be outside in direct sunlight or around bright studio lights, the glare alone can make it difficult, if not impossible to focus the camera. When mounted over the camer's LCD screen, the VF Prime PRO introduces stability by providing another point of contact with the body. Holding the eyepiece up to the eye not only helps stabilize the camera, it eliminates glare which makes it easier to focus and frame shots. And for those of us with less than perfect eyesight, the 3x focusable magnification makes shooting on a DSLR a lot easier! Strong Aluminum Construction The Prime PRO's housing is now a forged aluminum which is still light as in our past plastic model, yet super strong and durable. This is especially important to filmmakers who are constantly packaging, unpacking, assembling and shooting in less forging production environments. 3x Magnification One of the things most DSLR filmmakers must contend with is the relatively small LCD screen used to frame and focus their scenes. Holding the DSLR out in front while trying to steady and focus the camera at the same time can be quite challenging. Adjustable Focus The VF Prime Pro was developed to give filmmakers the capability to adjust focus to +/- 4 diopters. Having the ability to adjust the focus of the VF Prime means filmmakers can remove their glasses and comfortably place their naked eye up against the soft rubber eyecup of the viewfinder, thereby creating a seal that blocks all external light.
(6)Astro-imaging is an immensely rewarding hobby, but the challenges involved can seem difficult to beginners. Some of the best objects to start on are the planets of our own solar system and the Moon. Big, bright targets like Jupiter, Saturn, Mars and the Moon make wonderful models as they strut their way around the Sun on their celestial catwalk. The planets are relatively easy to locate and identify in the night sky, so solar system objects prime imaging targets for all astro-imagers. The Orion StarShoot Solar System Color Imager IV is equipped with features that make it easy to take your own images of objects in our solar system. Its 1/3-inch format CMOS imaging sensor with a 1280 x 1024 pixel layout can take sharply detailed planetary and lunar images. Each pixel is a mere 3.6µm x 3.6µm in size for exceptional image resolution in 24-bit RGB color. Since the 8-bit output StarShoot Solar System Color Imager IV is progressive scan, all pixels will be used for each and every exposure. At full 1280 x 1024 resolution, you can capture up to 15 frames per second. By stacking multiple exposures to create a single picture, you can increase image detail significantly.
Baader 2" Clicklock Clamp M56 for Celestron/Skywatcher
In addition to Baader's highly acclaimed 1 1/4" Clicklock clamp, Baader has done it again by creating their 2" Clicklock clamp for Celestron/Skywatcher using 56mm Thread. This new 2" Clicklock eyepiece clamp is innovation at its finest eliminating the use of thumbscrews and bulky holders. With a simple twist, the 2" eyepieces and accessories are securely locked into place with strength and support that can hold the entire telescope without slippage.
All it takes it a grasp of the rubber-knurled outer collar and a light twist. The three point clamping of the Baader 2" Clicklock Adpater ensures consistency in centering and eliminates any wobbling among the telescope. A 20 degree rotation is all that is required with little force to rotate. No longer will you have to worry about sag or misalignment by incorporating a Baader 2" Clicklock Adapter.
