Description

NGC 891 is about 32 mly away.  I imaged this with my 20 + year old Orion brand Maksutov Cassegrain Telescope.  This is a Russian made telescope built like a tank.  Its an 1800 mm FL, 150 mm (6"), at f12.  I used a Celestron 6.3 focal reducer on the 2 inch Crayford focuser. ASI Air Pro plate solved it at 1325 mm.  I used 49 mm back focus.  I couldn't add any more or I would run out of focus but the stars seemed to be nice and round.
