    Hello !
    With a F=1300 mm and D=102mm, the smaller magnification you may have is (pupil exit of 6mm) 17 and the focal length of the eyepiece is 76 mm !!!
    With such refractors, you'll have the downside of Cassegrain or Maksutov scopes (long focus) with a small aperture. In my opinion, the main advantage is the aberrations are easily (read with less money) corrected.

    Nice to see long focal length designs. While not overly versatile one would argue these "classic" refractors are pretty cool. The main issue is with mounting such long refractors they need something rather more sturdy than your average mount.

    While not at the level of an f15 refractor I've always fancied one of these (f/11) Before they had in pearl white.

    Yes but it's the sub aperture corrected 300mm Mak that might cause me to skip lunches. The price may well put me off though......

    Nope! Second read found price. I may be doomed.

    I found the Mak quite interesting adaption of the design. I am looking forward to seeing some reviews of its perfomance.
