Draw a line through the three bright stars in a straight line on the right side of M74, carry your view onalong that line to the lower left just abve the bottom are to two faint background galaxies.
Thanks Glen - I've probably been a bit harsh on the black clip, as in the raw stretched luminance image they're everywhere. It's amazing to think we can image these anonymous gx with such small scopes these days.

You might be able to get a bit more out of your
picture if you make a pseudo luminance layer from the RGB data & blend it with the actual luminance.
The video is interesting too.

Thanks Allan - I'll definitely revisit this one next month and get some more data too.

Hi Pat - it's a nice open area out near Talbot Hall, just 10 minute this side of York. Usually infested with a few >20" dobs around new moon...

I agree with mnt the video is excellent
Cheers - the D800 has a built in timelapse mode that's pretty foolproof!

I don't think I've ever had a night's imaging go smoothly! Like you say, there's always something. This time the meridian flip failed for no apparent reason too. It's as if the thing has moods...
