Last night was a night of fast moving patchy cloud, so every exposure was affected to a certain extent. Still, here is a stack of 20x300secs of NGC6946 or the fireworks galaxy, distance 22 million light years. Scope was the Altair Astro 102 ED-R at prime focus. Camera was the Starlight Xpress SXV-H9C.

I am very much out of touch with the night sky (Deep Sky in particular!) I don't recall having heard of the "Fireworks Galaxy" before - the name did not initially seem obvious to me, but I think the unusual "upper & lower bits" justify the name & you got a super image needless for me to say, despite having less than perfect conditions.
Best wishes from Cliff

Thank you Cliff. :)
The Fireworks galaxy is between Cepheus and Cygnus. I must admit I'm "discovering" new objects all the time. That''s the advantage of GOTO mounts and CCD cameras. I remember star hopping with my home built 9" reflector and when and IF I found the desired object, it was merely a fuzzy patch to the eye. And now of course my 62 year old eyes are not so sensitive! :D

That's a very nice image.

Cliff.
The name refers to a large number of T1 Supernovae recorded in this galaxy.
