• 2" Glasspathcorrector^® Factor 1,8 for Newtons - at full aperture with integrated Coma-Corrector
• Suitable to insert into the Baader Maxbright and Mark V Großfeld Binocular viewer (insert diameter: ∅ 2" - 50,8mm, incl. M48 filter thread)

• Includes 1x Baader Molded Plastic Cap T-2 for Zeiss Quick Changer (#2904020 , € € 6.50)

• High-quality lense system with apochromatic features, for magnifications from 2x
• Modular design for visual and photographic (VIP) use
• suitable for 1¼" and 2" focusers

• Coma corrector for Newton telescopes, that reduces neither the focal length nor the image field of your telescope
• Large lenses for completely vignetting-free exposures up to f / 3.5. Maximum sharpness over the entire image field
• Phantom Coating™ Group multicoated for maximum transmission and total freedom from reflections
• Next to the photographic only version, there is also a visual version that contains all parts of the base elements as well as additional adapters for visual application:
  • 2458400A: Photographic Version with removable 2" Stoppring, usable either with T-2 (M42x0.75) or M48x0.75 connection
  • 2458403: Visual Version (V-1 Set) contains all parts of the photographic Version MPCC Mark III #2458400A as well as 1¼" to T-2 focusing eyepiece clamp (#2458125) and adjustable VariLock T-2 extension tube 20 – 29 mm (#2956929)

Please note: This set replaces the former set #2458402 for visual and photographic application of the MPCC Mark III. The old set consisted of a multitude of rings – but was not adjustable in optical length such as this V-1 set.

The idea for this new and much more versatile set was born after we received this detailed question regarding eyepiece adaptation on MPCC, where we recommended our VariLock and focusing eyepiece clamp as best accessories.

• unique and extremely versatile telecompressor system that delivers the finest wide flat fields your SCT is capable of
• The result is a sharp, wide, flat field, at a fast focal ratio of f/5.9, optical length <50mm
• Please Note: The close coupling required for the telecompressor to reach focus with binoviewers limits it's use to only the Baader/Zeiss and Celestron binoviewers.
