@MrDiamonds01 8" (200mm) Dobsonian if you can maintain it, eitherwise any good refractor goto.

@nehal0001 no prob...i'm glad you are having fun with that scope

@animedrawer84 thanx for d advise but now i hav purchased dat telescope and quite happy wid dat

[animedrawer84]

@nehal0001 you should try to get a refractor between 80mm to 100mm of aperture......the 4mm eyepiece would give you a 175x magnification which to me is a lot for that scope...my advise is try to avoid it and get a 4.5 to 8 reflector or a 80mm to 100mm refractor... and buy a well known brand like orion celestron or meade
