This was taken using a 90mm Triplet APO at F5.2
Camera was the new Atik 460EX.
Ha Filter , 6 X 10mins exp , Off axis guiding.
About the first chance to use my new APO.
Wanted to get an idea of the field of view and to check
the focal reducers spacing was correct.
460EX has certainly managed to pick up some fine
detail in a rather faint object.
