Telescopes are a cheap alternative if you are willing to live with its drawbacks. My own experiences are that in a lot of cases, the massive increase in focal length can compensate for a lack of sharpness. I owned an AF-S 80-200/2,8 and used it with a Kenko DG 1,4x TC, resulting in 280mm focal length. Even stopped down to f/8, the photos I got with a modified Bresser Messier 1000/102 simple achromat beat it multiple times.

Sounds interesting, Christian... what I've always wandered is whether the telescopes with any built-in focusing mechanism allow for the sorts of close focusing that we do for terrestrial photos?
GTW
EDIT: wondered* lol
