| This image is compiled from
luminance data of 9 - 10 minute subs, 6 - 10 minute subs of Red, Green
and Blue. This image suffers from need of more data but was done to test
the optics after cleaning and re-collimation. Overall, I can say I'm
very happy with the results. The telescope was guided using the remote
guide head connected to the SBIG ST10XME mounted to the AP guidescope
using 3 second guide exposures. |
