Here is my second image for 2008, M57. It consists of 31 x 1 minute images along with darks, stacked and processed in Astroart 3, and final tweaks in Paint Shop Pro 7.

The setup used is an APM 130mm CNCII @ F/6, on a GM8 Gemini, and a Canon 300D, all unguided. The FOV is much larger than that shown. I cropped about 75% and enlarged the image by about a factor of 5.

Comments and feedback welcomed!

Thanks!


Joe

Not bad for such a blown up shot. This really shows off the tracking of your GM8. (unguided!?) I would have expected more color available for the stars with one minute exposures though. (?) Any available?
