The Baader Planetarium MPCC enables owners of fast Newtonian telescopes to use their instrument for taking stunning wide-field images, or visually, for delivering wide-field views with stars that remain pinpoint to the edge - with no magnification increase!. 

The MPCC has been optimized for Newtonians with focal ratios from f/4 to f/6, and will deliver 12micron stars across a full 35mm frame size.  Independent optical laboratory tests (by ITE) have confirmed that the MPCC is the sharpest wide-field coma corrector available for imaging, and provides the best edge of field illumination.  Visual users have reported great results even down to f/3.7.  The optics are anti-reflection coated with the finest 7 layer multi-coatings available.  The MPCC is also priced very reasonably.  It's modularity lets you purchase only the parts you need.  For imaging with DSLRs, only the MPCC is required.  For visual, the MPCC can be configured with any of our eyepiece holders or directly coupled to 2" eyepieces using Astro T-2 System components.

VISUAL

NEW !   Dob users with f/3.7 - f/5 scopes have been discovering the unique benefits of the MPCC versus other coma correctors.  The MPCC can be inexpensively configured for visual use with 1¼" and 2" eyepieces.  Please see our MPCC Visual Configuration page for new information on some exciting visual configurations. 

• No Magnification Increase:  The MPCC delivers full fields for the widest 2" eyepieces.  Why spend the big $$ on a large widefield eyepiece, only to have its field squeezed by the coma corrector.  Now, a 31mm ultra-widefield eyepiece can perform like a 31mm, and not a 26mm..  Also, unlike some correctors, the MPCC has minimal effect on the eyepoint and blackout behavior of long focal length eyepieces.

• No additional Back-Focus (in-travel) Required:  In fact, in direct-coupled configurations, the MPCC actually increases back-focus by about 10mm.  If your eyepiece will focus without a coma corrector, it Will reach focus with the MPCC.  This is not the case with some other coma correctors.

• Reduced Vignetting:  The MPCC works well with even the largest true field 2" eyepieces.  Due the closer position of the field lens to the focal plane, the MPCC is able to provide a larger fully illuminated true field than some coma correctors (both visually and photographically)

• Low Cost:  The MPCC is about half the cost of other correctors.  Some users have even purchased more than one and leave them permanently attached to their favorite 2" eyepieces.

IMAGING

The MPCC is the ideal match for today's Digital SLRs.  Owners of these new cameras find them to be ideally mated with today's fast f/4-f/5 Newtonians required to keep exposures short.  The MPCC enables these users to fully correct their scopes and produce superb pinpoint color deep sky images without the complexity of more expensive CCD astrocameras.  Owners of Vixen Newtonians will appreciate the inclusion of filter threads, and the high sharpness of the images.  Unlike other coma-correctors, the MPCC does NOT extend the focal ratio (so, your images will be shot at the full speed of your telescope).

The MPCC inserts into 2" focusers and has external T-threads on the output side (and is also threaded for standard 2"/48mm filters).  Simply attach any 35mm film or digital SLR to the MPCC, using commonly available T-adapters.  Users of CCD cameras can attach in the same way through the use of our Astro T-2 System components (adapters, extension tubes).   The MPCC is designed for a nominal 55mm distance from the mounting flange to the film plane (55mm is the standard dimension for all SLRs, measured from the front of their T-adapter to their film plane). It also extends the focus point by approximately 10mm, so no additional back-focus is needed to use the MPCC (of course, this assumes your camera will already reach focus in your telescope, without the MPCC).

NEW The latest version of the MPCC now includes a removable stop flange.  Removal of this flange exposes an M48 external thread, which enables the MPCC to be directly coupled to 2" eyepieces and inserted fully inside 2" focusers.   For more info, please see MPCC Visual Configuration.

NEW The MPCC has been tested and found to work well on Meade SN Schmidt-Newtonians (see Bill Christie's comments below)

Please click on the thumbnail below for an example of the imaging improvements from using the MPCC.   These images were sent in by one of our customers using a Celestron 8" f/5 NGT, using a Canon Digital Rebel (300D) at prime focus with and without the MPCC.

"Using the Baader Multi-purpose Coma Corrector from Alpine Astro the coma in my 12-inch f/5 telescope is gone - wow! - my images are now flat across the entire field, and I find that amazing, since this telescope previously produced a moderate to large amount of coma in my images.  The other delightful thing I found was the MPCC screws straight into the bottom of my 2-inch eyepieces.  Thanks Baader, Thanks Alpine Astro."   Paul Mayo, SKY:Lab Astronomy Software

Conclusion: A Baader MPCC Coma Corrector with proper collimation, tracking and good focus WILL give you pinpoint stars in your photos, right across the field of view (1.6 degrees in an SN-8). The Baader MPCC Coma Corrector joins the Telrad and Accufocus in my list of MUST-HAVE equipment (for astrophotography) when using a Meade LXD-75 SN-8.

The weight of the MPCC by itself is 80gm (2.8oz).

A common limitation that plagues owners of most popular Schmidt-Cassegrain telescopes is the narrow field size and high magnifications produced by their slow optical system (typically, f/10).  Until now, owners of SCTs have lacked a truly versatile and high-quality method of reducing their f/10 (or slower) systems for faster, wider, photographic/CCD and visual fields. (note: the telecompressor is not intended for use with the Meade native f/6.3 SCTs).  Using the Alan Gee with 1¼” eyepieces can yield actual fields of view that match or exceed what you could only achieve with expensive 2" eyepieces!

Baader Planetarium has developed a truly unique and  extremely versatile telecompressor system that delivers the finest wide flat fields your SCT is capable of.  The key to the Alan Gee Mark II Telecompressor is its innovative optical and mechanical design.  Unlike the commonly available and simple single-purpose solutions, the Alan Gee Telecompressor Mark II has been engineered specifically to work well with SCTs in a wide variety of visual and imaging configurations.   The unique design of the Alan Gee Telecompressor positions the lens elements several inches inside the telescope's central baffle tube (see the C8 Cutaway, which shows the lens mounted in the standard imaging configuration).  The result is a sharp, wide, flat field, at a fast focal ratio of f/5.9 – and it even works superbly with Baader Planetarium, Zeiss, and Celestron Binocular Viewers!

That's right.  The Alan Gee Mark II is designed to function with many popular  binocular viewers.  At last, you can use your large aperture SCT to produce stunning wide field binocular views.  For more information on this unique telecompressor system, including some sample CCD images, please click on the link below.
