NGC 5566 sprial galaxy type SBa, with NGC 5560 spiral galaxy type SBb/P (upper right), and NGC 5569
sprial galaxy type SBc (upper left) in Virgo. Together these are also cataloged as Arp 286. Taken
May 3, 6, 9, 26 and May 27 2008 with a DSI Pro II and Outback Cooler, on a C8NGT (8" Newtonian f5)
and an ASGT mount. LRGB subframes were 3 minutes each. The RGB frames where also used to create
synthetic L subframes which were then combined with the actual L subframes to give the following
total exposures (sL+L):R:G:B (min) = (117+165):123:132:117. Color balance was achieved via
numerically scaled channels. Captured with Envisage, calibrated and sigma combined in Iris with
other processing using FITZ, PixInsight LE and Photoshop CS. North is up.
