[QUOTE="Pierro, post: 99822, member: 8517"] More info required - are you using prime focus astro pohotography, or are you using eyepieces ? If prime, ( no glass, eg lens or eyepiece, between camera ) then you cannot zoom. Scopes dont zoom, unless you use eyepieces, and even then you would need a zoom eyepiece. You must have a fairly big astro lens to be filling the viewfinder so much you need to rack out. My previous 600mm scopes would easily see the whole moon and then some. What exactly are you using Patrick ? By the way, assuming its a refractor, you can stop down but its far from technical and very easy to do [/QUOTE]
