I am evaluating lightweight (60-70mm) telescopes to use with a tracker mount. The purpose is to be able to take the equipment by plane without major problems. It gives me the impression that most of the tubes with these characteristics are manufactured by 1-2 manufacturers and the differences are in the quality controls umposed by the companies that sell them under their brands. I think that is the reason why the reviews that I have read about Altair, SharpStar, AstroTech, William Optics, among others are inconsistent ... But…I am not sure if quality control is the only issue at play, or if they are also a result problems created by non-skilled users.
After much reading and evaluating I am between one of these options: (1) I go totally crazy and buy the Taka FS 60 (doublet) with its reducer flattener and other accessories and present my case to the bankruptcy court. (2) A Samyang 135mm lens and get the Deep Sky Dad adapters for use with an electronic focuser (3) The WO Zenithstar 61 with its flattener (4) The Altair Astro 70 (triplet) with its flattener / reducer.
If you have any of these, I would appreciate if you can share some of the images you have taken as well as your impressions about the quality of it.
