Observing location

40s at 1600iso (25 subs)

I timed two lunar Occs in Earth Shine and moved on to Panstarrs before the predicted cloud arrived. Collected 30 subs of 40s, discarding 5 due to RA shift (no autoguiding). The image includes 3 darks and was stacked on the stars with DSS, using FITS as intermediate file. Processing was in AstroArt 5. Image orientation has North up.  I used  "remove gradient" in AA5 to take out vignetting.
