M34 in Perseus


Scope: Megrez II  f/4.1; Location:  Del Mar CA;  13 Oct. 2004; Camera: ToUcam SC3

Exposure: 25 x 12 sec  and 20 x 3 sec Luminance exposures with Baader IR Block Filter; 15 x 12 sec RGB 

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.  The shorter Luminance exposure was combined with the longer one to reduce star bloat in the Luminance construction. 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 exposure was taken in a fairly light polluted area - but this open cluster is bright enough to punch through it. This is one of two well known open clusters in Perseus (along with the "Double Cluster").  Horizontal FOV is about 50'.
