G1

#1

Post by KathyNS »


After seeing Steve's (@sdbodin's ) image of globular cluster G1, which belongs to M31, I got bitten by the "I gotta try that" bug. I will have to try this again next spring when I have the C-11 mounted for galaxy season. It was a bit silly trying it with only 926mm of focal length. Nevertheless, G1 is more than 6 pixels across, and it is (almost) recognizable.

Good get. This cluster is quite bright and easier to image than I thought. However seeing it with our short focal length scopes as anything other than a 'star-like' point will be very difficult.

Clear skies,

With a little imagination I can see the cluster! You did all you can do with that aperture. Look forward to seeing it with your larger telescope next year.
