Meade Advanced Coma Free Optics (ACF) Optical Design

The science behind the Meade f/8 optical tube starts with their patented ACF optics.  Improving upon the original Schmidt Cassegrain design, Meade's ACF optics deliver the ultimate in clarity, contrast and flat field of view. Natural coma and optical abberations are eliminated allowing for pin point round stars to the edge of the field.  These qualities make Meade ACF optical tubes excellent imaging instruments.   However, by pairing this revolution in optical design with their Ultra High Transmission Coatings (UHTC), light transmission and detail are greatly increased allowing you visually discern fainter objects than ever before - an observer's dream!   This OTA is built for speed too.  Traditional Schmidt Cassegrains would typically have a field stop of f/10, at only f/8 your exposure times are exponentially decreased allowing you to get more imaging in each night.  



  • ACF (Advanced Coma Free) Optics for maximum sharpness and clarity. 
  • UHTC (Ultra High Transmission Coatings) for 20% more contrast and brightness when compared to Meade's original optical coatings. 
  • 7:1 precision focuser with zero-image shift.
  • Losmandy style dovetail for fast and easy attachment to your choice of mount.
  • Includes Vixen style, top mounted accesssory dovetail to readily accept a wide variety of accessories including guide scopes and cameras. 
  • 8x50 optical finder
  • Series 5000 2" diagonal
  • 25mm HD-60 Eyepiece

Questions & Answers

Product Questions

How is the optical performance of this scope for imaging with an 8300 chip?
Hi: Can you change the position of the dovetail bar? I would want to move it 90 degrees from position shown in the picture to accommodate my mount. Thanks,
Which version of the Flexible Dew shields would work on the 10" F8 ACF OTA given the position of the dovetail plate and its mounting bracket. Also, how would you rig a heating cable given the dovetail location. Thanks for your answer
Hi:  Is the visual back a true 2" visual back, so that there will be no vignetting when using a 2" diagonal and 2" eyepieces? Other than a mount, eyepieces, dew shield and dew heater, is there anything one would need to start using this? Thanks!
Would the vignetting on a full frame camera such as a Canon 6D still allows for good pictures? How about with APS-C?
Hi: Can the included finder scope be set-up with a right angle diagonal to improve ease of use? Thanks!
Is it possible to assemble the new OTA 10" to an old field tripod and mount from year 1990, to install it to the go to system and make it work?

Who can do this installation?
Hi Chris: Thanks for the answer on moving the dovetail. Follow-up: I see in the picture 1. the finder scope and 2. another mounting bracket. Can this mounting bracket be moved also?
