G,day Smenkhare and welcome to IIS
I had a look at the link to andrews and I have a few suggestions for you. It is my humble opinion that the skywatcher 76 is too small for serious observing. Your best bet (on the Andrews site) is the Guan Sheng 150mm (6") Dob for $299 or the GS 200mm (8") Dob for $399. GS Dobs are very capable telescopes, I own 2 my self
Cheers, Mick.
