Hi again

Thanks for your responses, you've given me food for thought. As far as how I got Mag 18.8 it was about 20 x 5 sec exposures and yes I'm playing in the noise. I'd realistically be getting Mag 17ish as part of an automated search with maybe 1 square degree of coverage per night. Yes I'd be pushing it uphill for asteroid hunting. There seems to be minimal surveys down < -60 Deg Dec. Slim pickings but might be my best chance?

higginsdj - your site is great, Very useful. What is Giant Planet moon astrometry. Jupiter and Saturns moons? What does the astrometry of these bodies help with?

Still not sure what I'm doing but thanks again.

Peter
