M63

M63, the Sunflower galaxy, imaged over 3 nights last week. 66 x 2 minute luminance and 22 x 2 minute exposures for red, green and blue. I used my Starlight Xpress 694 mono ccd camera, binned 2x2, with the 6 inch Ritchey Chretien on my new Cem70 mount. I used 2 minute subs because my guide camera was playing up! I followed Paul Howat's suggestion about running the subs through BlurXterminator on the correct setting using an image container and creating a process icon to run BlurX, it appears to have worked well. I then used WBPP to stack all the images together with calibration frames. I'm very pleased the final image turned out so well, I've never seen that extra ring around the Sunflower.
