I would like to keep this topic on 50mm or smaller refractors and 3" or smaller Newtonians and Maks.I've only had a couple of tiny classics like the Tak FC50(which I still own), Meade's 50mm x 600mm model 155 and that Tal 65mm Newtonian.
What type of observations have you done with yours? Lunar, planetary deep space? My little FC50 surprises me every time I use it (which isn't much). With some patience and careful observing I have seen considerable detail on Jupiter including the GRS. The moon goes without saying, tons of detail there and some of the brighter M objects from my light polluted skies. Have you ever taken yours to a dark site?
