TS Optics 10″ f4 Newtonian, asa 0.7 reducer, atik 314L ccd, neq6 mount.

M33 Triangulum Galaxy taken with my new scope and reducer. x11 5min subs clear filter x6 5min subs each R/G/B. The reducer takes the speed of this scope down to about f2.9 which is very fast! It’s great for uk skies but has taken me a while to get the collimation right. This is my first image that I’m really happy with.
