Sharpless 264 (Sh2-264)

Sharpless 2-264 (Sh2-264) HII emission nebula and open cluster Collinder 69 (CR 69) in Orion.
Sharpless 2-263 is also visible at roughly the 4 o’clock position about 2/3 of the way to the
edge. Taken Jan 15 & 17 2008, with a DSI Pro II with an Outback Cooler and a Pentax SMC-M 28mm lens
at f3.5 on an ASGT mount (not guided). H-alpha subframes were 8 min, while the GB sugbframes were
1.5 min. (The B subframes were taken with an Orion Skyglow filter to control star bloat). The
resulting total exposures were Ha:Ha:G:B (min) = 288:288:60:75. 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.
