Hi, Mate could you tell me if this scope is an apochromatic telescope, not that great with Refracters, ive had a dob for 12 years or so. Iam new to refracters, so i am depending on you for the info. This scope should be pretty good for Photography shouln't it?..Plud what doe's SD doublet mean?..Thanks LLoyd...

Not to invade on Stephen's thread, but this scope is whats known as a Semi-apo..

See the william optics website (http://www.williamoptics.com/telescopes/zenithstar66sd_features.php) for detailed info..

To clear up the confusion, I have just taken a pic of the objective lens of the Z66 which shows that it is the doublet APO model.
