Cost all of $125, many thanks to Lars for the sale....a great small scope for Planets and G+G.
My recommendation is a 4" f15/3.5" Achro or an ED 100. |
I wouldn't go over 900mm in focal length without compromising the stability of my mount, so no f/15 for me!
I wonder if the dual-speed focuser on the current Synta scopes is better than the old one.
