I'm also looking for a small portable scope.
My selection at the moment is Orion ED80 apochromat on an AltAz mount.
I think the 90mm refractor is cheap and the ED80 gives a better view.
If I can squeeze my budget I would pick the Orion EON 80.
Also for consideration is ED APO 80mm f/6.8 refractor from Andrews. I would like some opinions on this OTA.
My choice is also influenced by the future use for imaging
Looking forward to other comments.
