Hello again! (Mum on behalf of MITM)
Well we are about to place an order for an 8" Dob (Tim has been saving hard!
) and wondered what sort of extra eyepiece we ought to buy as well (if any?) as we've read a bit about Barlow lenses etc but wondering about which brands are good quality. (I'd imagine as with most things price reflects quality)
Here's the specs on the scope if that makes a difference in what type of Barlow we should get:
Skywatcher SW680 Dobsonian
Optical Design: Newtonian paraboloidal
Diameter in mm: 200mm
Focal Length in mm: 1200mm
Focal Ratio: f6
Highest Practical Power: 400X
Faintest Stellar Magnitude: 14
Resolving Power (arc sec): 0.86
Finder-scope: Optical 9x50mm Focuser
Diameter: 50.8mm & 31.7mm
Eyepiece (s): S20 and S10 (31.7mm)
Mount Type: Dobsonian with tension control
Also interested in getting a reasonable set of binoculars for the other son to peer through while waiting for his turn on the big one so some details.... (BTW He wears glasses so I'm leaning to the Gerber)
