shot OSO 97 again (Halifax)

Before the clouds moved in, snapped some more frames of the double star OSO 97. Shot longer and used a different camera (the SBIG) from the run on 18 June.

double star OSS 97 in luminance

Luminance only, 15 seconds subexposures, 12 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

The clear sky chart predicted at this time there would be 30% cloud cover with average seeing.

Even thought the job was not fully completed, I like this result. While not perfect, it's better than the previous. Now I can see mag 17 and 18 and some 19 stars...

I dunno. I think I need to shoot longer again, under better conditions.
