Another short-frame exposure, this time of NGC 7331, a lovely galaxy in Pegasus, rather luminous and with a lot of “friends” around it.
The following was shot with the 355mm F/4.5, Baader coma corrector, and ASI174MM with no filter. Poor seeing and not so great transparency, all on +5 mag suburban skies.
Only 500 frames for this image, each a 3 second exposure. It definitely deserves another session under better conditions, and at least 2000 frames.
