Description

Backyard HO (with LRGB stars) 4-panel mosaic of LBN 576 (Abell 85) taken from suburban Silicon Valley skies. It was shot on 39 different nights between mid August through the end of October 2023.  The date given is the first day of collection.

Not an ideal subject for my 10" RC and location, as I needed a 2x2 mosaic to capture it, and it is very faint so it demanded many hours of exposure. In the end I collected over 25 hours each of H and O data for each of the 4 mosaic partitions, over 39 different nights of differing quality.

The number of hours of exposure (> 200 hours) is misleading as each of the 4 mosaic panels has roughly 1/4 of that much exposure, so it's more like 50-hours of exposure from my house.
