Clear and steady skies with good seeing. Maxim's guiding error was around 0.4 arcsec on both axes of my 1200 mount.

Comments welcome.

That is indeed a faint object, nicely done. Unfortunately I tried a 5 minute shot of luminance and got nothing but sky fog due to my severe local light pollution. I pretty much need to stick to narrowband images here.
