Baader Multi Purpose Coma Corrector (MPCC Mark III)

Baader Multi Purpose Coma Corrector (MPCC Mark III)

The Baader Planetarium Multi-Purpose Coma Corrector (MPCC Mark III) 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 Mark III 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 Mark III is the sharpest wide-field coma corrector available, 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 Mark III is also priced very reasonably. It's modularity lets you purchase only the parts you need. For imaging with DSLRs, only the MPCC Mark III is required. For visual, the MPCC Mark III can be configured with any of our eyepiece holders or directly coupled to 2" eyepieces using Astro T-2 System components.

Using the Baader MPCC Mark III for Visual Astronomy

Dobsonian users with f/3.7 - f/5 scopes have been discovering the unique benefits of the MPCC Mark III versus other coma correctors. The Baader Multi-Purpose Coma Corrector can be inexpensively configured for visual use with 1-1/4" and 2" eyepieces.

No Magnification Increase! The MPCC Mark III 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 Mark III 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 Baader MPCC Mark III actually increases back-focus by about 10mm. If your eyepiece will focus without a coma corrector, it will reach focus with the MPCC Mark III. This is not the case with some other coma correctors.

Low Cost! The Baader MPCC Mark III 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.

Using the Baader MPCC Mark III for Imaging

The MPCC Mark III 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 Mark III enables these users to fully correct their scopes and produce superb pinpoint color deep sky images without the complexity of more expensive CCD astro cameras. Owners of Vixen Newtonians will appreciate the inclusion of filter threads, and the high sharpness of the images. Unlike other coma-correctors, the MPCC Mark III does NOT extend the focal ratio (so, your images will be shot at the full speed of your telescope).

The Baader MPCC Mark III 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 Mark III, using commonly available T-adapters. Users of CCD cameras can attach in the same way through the use of Baader Astro T-2 System components (extension tubes). The MPCC Mark III 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 Mark III (of course, this assumes your camera will already reach focus in your telescope, without the MPCC Mark III).

The latest version of the MPCC Mark III now includes a removable stop flange. Removal of this flange exposes an M48 external thread, which enables the MPCC Mark III to be directly coupled to 2" eyepieces and inserted fully inside 2" focusers.

The MPCC Mark III has been tested and found to work well on Meade SN Schmidt-Newtonians.

Questions & Answers

Ask a Question
  • I have a Schmidt Newtonian (F4).  If using this coma corrector, will I have to move the mirror(s) to reach focus?  Thank you for any information.

    If you remove the 2" focuser extension and thread the 2" adapter directly to the drawtube, then you should not need to move the mirrors when using an MPCC. You will need to refocus from not using an MPCC, but the difference should be slight.

  • I have an f4 Newtonian.  I want this corrector for visual observing, not photography.   I also have an adapter for my 1.25" eyepieces.   Will it work for that?

    The Manufacturer states that this corrector can be used for visual use. It will not require any additional back focus.

  • What is the difference between the Meade 8" LXD75 ACF UHTC Telescope (Item # UT-7681) and the 8" LX200 ACF OTA w/ UHTC (Item # UT-7680)? Is the LX200 a better quality scope?

    The most significant difference between the two tubes is mechanical: the LX200 OTA units have mirror-locks, like their fork-mounted siblings. The 8" ACF tube that was packaged with the LXD75 is the same model (though in a different color) as what Meade in

  • Would this work behind a focal reducer on a Schmidt Cassegrain? When I image with a focal reducer I get too much coma.

    Unfortunately no. This coma corrector is designed to only work the Newtonians.

  • Will this work with a CCD camera with a 1.25" nosepiece, or must the camera be screwed into the unit?

    Ideally, you would want the camera to be screwed into the MPCC for stability, but you could potentially use a low profile camera with no filter wheel and a 1.25" nosepiece with additional accessories. The best corrected position position with the MPCC is
