Exposure: 15 x 32 sec and  24 x 10 sec Luminance exposure with IR Block Filter; 12 x 32 sec RGB 

Processing: Images were captured in K3CCDTools. Aligned/stacked in Registax and saved as FITS. Luminance and Color channels were scaled and rough color balanced in Astroart. Channels were co-registered in Astroart.  The shorter Luminance exposure was used to reduce star size on the larger stars. Luminance and Color FITS were combined in Photoshop with Luminance Layering. . Color balancing and final touches in Photoshop. SGBNR  (PixInsight LE) was used to smooth background noise on the luminance channel and the final result. Resized to approximately 800x600.
