Scope: C8  f/2.6 Location: Dos Picos Park, Ramona, CA   14 Jan. 2005  Camera: ToUcam SC3

Exposure: 16 x 32  sec and 18 x 10 sec Luminance Exposure with IR  Block filter. 6 x270 sec H-Alpha Exposure  12 x 32 sec RGB Exposures

Processing: Images were captured in K3CCDTools 2. Aligned/stacked in Registax 3 and saved as FITS. Luminance and Color channels were scaled and rough color balanced in IRIS. Channels were co-registered in IRIS. The Nebulosity was extracted from HA and then combined with the 32 sec IR  for Luminance in Photoshop - The 10 sec IR was used to minimize some star bloating.  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  Luminance channel as well as the final result. Image was resized to 800 x 600.

This image was taken at a dark site. This was a guided image.  The Medusa Nebula has a catalog designation of PLN205+14.1. It is actually a planetary nebula that images well in the H-Alpha emission band. Horizontal FOV is 30'
