This is a stack of seven 8-second exposures of M57, the same object I posted earlier in the month. It was taken with my 130mm f5.7 reflector and a Meade DSI CCD camera on October 6th, 2007. I feel much better about this image than the last one. I aligned the telescope more accurately and used the FTS format image capture technique to take seperate RGB exposures. I then used GIMP 2.2 to combine the three colors into one final image. I processed it only slightly to brighten the whole image in an effort to bring out more detail.

I find this very interesting. Some time I would like to know about your experience working with GIMP--whether you would recommend it. I have been at the point of downloading it, but wasn't sure if it was worth the hassle to do the extra things required to install it.
