Posting this as its a first light for a SW ED72. Unguided 90sec on SW Star adventurer with Mod 500d using Astronomiks 12nm Ha Filter. Dithered and darks
I got 180sec unguided on a test shot also.
Pretty happy with this portable set up now that I can get closer to the targets than my 135mm.
40 x 90 sec Total 1 hour exposure time.
