The ring is a beautiful planetary nebula. This image represents first light for my new color filter wheel, no more B&W images! Yahoo! I ran into multiple problems and am still on the uphill side of the learning curve.

Although I spent considerable time aligning the Hydrogen Alpha, Red, Green and Blue channel images, there is still some misalignment that can be seen as odd star colors for stars at the edges of the image. In addition, my blue data was rather weak even through I was using 50% more exposure time than with the Red and Green channels. This bears watching, it may be that the camera has low quantum efficiency in the blue wavelengths and I may need to up the blue exposure times to compensate.

But, it was high over head, I got some good data and am pleased with my first color image.
