Baader 2" Multi Purpose Coma Corrector - MK III
The Baader Planetarium Multi Purpose Coma Corrector has been optimized for Newtonians with focal ratios from f/4 to f/6, and will deliver 12 micron stars across a full 35 mm 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 modular design 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 Baader's eyepiece holders or directly coupled to 2" eyepieces using Astro T-2 System components.
Dob users with f/3.7 - f/5 scopes have discovered the unique benefits of the 2" Multi Purpose Coma Corrector - MK III versus other coma correctors. The MPCC can be inexpensively configured for visual use with 1.25" and 2" eyepieces.
The 2" Multi Purpose Coma Corrector - MK 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 enables these users to fully correct their scopes and produce superb pinpoint color deep sky images without the complexity of more expensive CCD cameras.
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"/48 mm filters). Simply attach any 35 mm film or digital SLR to the MPCC, with T-adapters. Users of CCD cameras can attach in the same way through the use of Baader Astro T-2 System components.
The MPCC is designed for a nominal 55 mm distance from the mounting flange to the image plane. It also extends the focus point by approximately 10 mm, 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). The latest version of the MPCC now includes a removable stop flange, which when removed exposes an M48 external thread, which enables the MPCC to be directly coupled to 2" eyepieces and inserted fully inside 2" focusers.
