Short focus Apos look funny. Sure, less space- but less beauty, less grace!
I don't mind the looks, but they can be hard to balance, because the tube is so short, the point of balance often lies somewhere in the focuser - or even behind it! I also don't particularly like that if I want to reach high magnifications I need to pile on the barlows.
Some say that the most useful feature of the short focal length apo is their ability to give a very large field at low magnification. That's fine, of course, but I rarely use that feature, preferring to use medium and high magnifications and here a longer focal length is preferable. If I want very low magnification and a large field, I use binoculars.
