NGC896 in Cassiopeia


Scope: ST80  f/2.5 Location: Tierra Del Sol CA   12/30/2002  Camera: Vesta 690

Exposure: 5 x 240 sec  and  10x 60  sec color frames with IR block  filter

This image is a combination of exposures with the shorter exposure used to reduce bloating of the brighter stars There was some noticeable coma in the lower corners. I am not sure of the cause other than perhaps less than optimum focus made worse at the edges. This particular night I was with a friend and we were literally chased inside by a very heavy dew. The image was taken just as condensation was starting to form on the objective - even with the dew heater at full tilt. Horizontal FOV is 72'
