Is there a particular reason you want a zoom lens? A prime lens would most likely be sharper and provide a better image. For the prices you are looking at you could get an Orion ED80 and WO 0.8X FR which would give you 2˚ 08' X 3˚ with a D70 or you could get an FS60-C Tak with a slightly larger FOV

Hi Paul. No zoom needed. I just want to do star fields and long exposures. Just looking at a thrifty option. I hadn't considered buying a refr... refraaacc.... refractor - there I said It! But it is worth a look.

Thanks
