Product Info

Manufacturer Description

The new Baader Planetarium MPCC MkIII 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/3.5 to f/6, and will deliver 12 micron 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/3.5. The optics are anti-reflection coated with Baader's Phantom Group Multicoatings. The MPCC is also priced very reasonably. Its modularity lets you purchase only the parts you need. For imaging with DSLRs, only the MPCC is required (for the maximum field size. The MPCC MkIII is designed to work perfectly with the Baader Protective EOS T-rings (sold separately). For visual, the MPCC MkIII can be configured with any of their eyepiece holders or directly coupled to 2" eyepieces using optional Astro T-2 System components.

New Features of the MkIII Version:

  • New Optical Design - calculated for an unvignetted field down to f/3.5.
  • Improved sharpness across the field.
  • Phantom Group Multicoated for maximum transmission and freedom from reflections from UV to NIR.
  • Attaches directly to the Baader Protective EOS T-ring (sold separately) through use of an optional adapter.
  • 44mm Clear Aperture when using the M48 (2") filter thread or the Protective T-ring.

 VISUAL

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 1.25" and 2" eyepieces. Please see the 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/3.5-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 the Baader 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).

The MPCC also 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 the  MPCC Visual Configuration page.

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

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

      5.0 correct coma without adding CA

      Pros:

      Cons:

      Comments:

      i was using a GSO coma corrector with my 8" F4 GSO Newtonian for astrophotography. it worked good for coma correction but it also introduced some heavy chromatic aberration to the image. so i have decided to try this. its twice as expensive and correct almost the same filed as GSO corrector. may be a little better. but most importantly it has no chromatic aberration that i can notice. so i'm happy with that.

      5.0 woke up from a coma (corrector)

      Pros:

      Cons:

      Comments:

      i tried another coma corrector, and it actually made coma where there weren't any. In contrast, the Baader Mark III coma corrector worked VERY WELL. I use both a 6" f5 and an 8" f5 orion reflector telescopes, and coma correction made almost the complete frame of a 35mm dslr usable. Highly recommended

      5.0 A "must" for imaging

      Pros:

      Cons:

      Comments:

      I had the GSO coma corrector I really liked using for visual. When I decided to use my 150mm F5 newtonian for imaging, I wanted a coma corrector that added no focal length. This is the corrector that does that and yields nice tight stars.

      5.0 SUPERB!

      Pros:

      Cons:

      Comments:

      I have a Televue type I Paracorr coma corrector and the Baader MPCC is superior in every way, but one. Both fully correct coma, but the Baader has noticably better contrast and light transmission. It's no contest. The Baader is like looking through a clear window. The Paracorr is hazy by comparison.

      As you probably know, the Baader has zero magnification, whereas the Paracorr magnifies 1.15x. The problem with the Paracorr is that the magnification pushes the exit pupil farther out from the top of the eyepiece, making it impossible to see the edge of the field of some eyepieces. I noticed this in particular using several 100 degree eyepieces, in effect making them approximately 90 degree eyepieces with fuzzy edges. But the Baader MPCC does none of this. The exit pupil stays put were it belongs, and you can see the entire field of the eyepiece as it was designed to be.

      If you read the astronomy forums, you may find people who claim the Baader MPCC is a two element Ross design, and as such, has spherical aberration. All I can say is, those people must never have looked through one, because there is no visible spherical aberration. Stars are perfect pinpoints across the entire field. By the way, the eyepiece I'm using it with is a 25mm Explore Scientific 100 degree.

      Now, the one downside to the Baader - it's not easy to position it relative to the eyepiece. It screws into the 48mm filter thread on the bottom of the eyepiece. Spacing is critical if you want to get the best performance. And the distance from the bottom of the eyepiece to the top of the MPCC is going to be different for each eyepiece. I bought a bunch of cheap 48mm filters of varying thicknesses, removed the glass, and used the rings to find the right combination to position the MPCC for my particular eyepieces. As such, it's probably best to plan on using the Baader with a single eyepiece, where you can keep it permanently attached at the correct distance.

      5.0 Works well!

      Pros:

      Quality Lenses,Lightweight,Compact,Strong Construction

      Cons:

      Comments:

      I use the Baader 2" MPCC with my Meade 10" Schmidt-Newtonian OTA at this time. I have not had the chance to use it with my 6" Schimdt-Newtonian, but it does work well for the 10". I can't really say that the stars are "pinpoint" on the outer edges, but a definite improvement is noticed. I also chose this over the Paracor because of pricing, weight and magnification. The Paracor is designed mainly for the Teleview eyepieces, of which I have none. Yes, it can be used without the Teleview eyepiece adapter, but why pay the extra cost when I only need the lense? I am pleased with this product.

      Pros:

      Quality Lenses,Strong Construction,Compact,Accurate

      Cons:

      Comments:

      My Baader MPCC gives pinpoint stars and accurate color rendition in the visual spectrum across my (medium-sized) ccd chip. I use it with 6" f/5 and 10" f/4.7 newtonians. I plan to use it with a faster 100mm f/4.25 newt. I would not image through a newt without this or a comparable product. Highly recommended!

      5.0 Performs at least as well as advertised!

      Pros:

      Quality Lenses

      Cons:

      None of the above

      Comments:

      I use my 8" f/4 Newtonian Astrograph with a Canon 350D DSLR equipped with the MPCC for astro-photography. I get clean, sharp, pin-point stars across the image. After my first attempts to image a Deep Space object, I wasn't particularly impressed. But then I read the instructions... Duh? After correcting my set-up mistakes, I was seeing some egg-shaped stars in one corner of my images but that problem was eventually traced to an out-of-square focusing extension. To say the MPCC works as advertised is a definite understatement.

      4.0 Baader MPCC for Visual Use

      Pros:

      Minimal weight,Gets the job done,Less expensive than other

      Cons:

      Has to be screwed onto EP,Selection of extension t

      Comments:

      I purchased the Baader MPCC for use with my 16" F 4.5 Meade Lightbridge dobsonian telescope. This scope has quite a fast F ratio so a coma corrector is required to get the best performance from widefield eyepieces. I did quite a bit of research before choosing the MPCC over the TeleVue Paracorr. The main reasons I picked the MPCC were weight, cost, and magnification. The MPCC is much less expensive and weighs about 5 oz. vs. 16 oz. On the 16" lightbridge that would mean 2 more pounds of counterweights on the back end of the scope (my particular one already has about 10lbs added to the back end). As far as magnification goes the MPCC doesn't change the focal length of the scope whereas the Paracorr adds 15% magnification. I'm primarily using this coma corrector with widefield, low power eyepieces so why would I want to increase the magnification?

      The MPCC works great when used with my William Optics 28mm UWAN and 20mm T5 Nagler, there is no coma visible once the corrector is in place. The tricky part of using the MPCC is figuring out what extension tubes to use with a given eyepiece. The Baader website isn't much help and the offered extension tubes are an oddball mix. It would be nice if Baader would offer a comprehensive set of extension tubes with logical lengths for use with the MPCC. As long as you are willing to fiddle a bit with extension tubes to get the right combination then the MPCC works great for controlling coma on a fast Newtonian telescope.
