M26 in Scutum


Scope: C8  f/5; Location: Del Mar CA;  23 Sept. 2004; Camera: ToUcam SC3

Exposure: 26 x 10 sec Luminance exposure with Baader IR Block Filter; 16 x 10 sec RGB  exposures

Processing: All exposures captured  in K3CCDTools. Alignment and stacking was done with Registax and saved as FITs. LRGB channels were co-registered in Astroart. Luminance and Color channels were scaled and rough color balanced in Astroart.   Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB). Color balancing and final touches were done in Photoshop. SGBNR (PixInsight LE) was used to smooth background noise on the luminance channel. Resized to approximately 800x600.

This image was an unguided exposure. This is one of the two Messier open clusters in Scutum (along with M11).  This is a summer Milky Way object that was imaged late in the season and my last summer Milky Way object for 2004. Horizontal FOV is about 16'.
