Ring Nebula M57


Scope: StarMax127 f/12 Location: Del Mar CA  5/10/2003 Camera: ToUcam SC3

Exposure: 10 x 60 sec Luminance with IR  filter, 12 x 30 sec each RGB  filter.

Processing: Captured aligned and stacked in K3CCDTools in 2x mode with L,R,G,B saved as FITs. LRGB masters were registered and combined in Astroart. Some Lowpass filtering was applied followed by un-sharp mask on the Luminance frame. LRGB result was saved as a BMP. The result BMP was level adjusted for smoother background in Photoshop.

This image was taken with the dual scope set up. This is one of my first images with my new camera. In addition, I used the Vesta 690 camera as a guide camera working on the ST80 at f/15, The guiding was done "semi automatic" with a second instance of K3CCDTools. The guiding calculations were made in the program and results were transmitted to the clock drive via my thumbs on the hand control buttons. In effect, the camera was the guiding eyepiece and K3CCDTools was the analyzer. Horizontal FOV is 18'
