Since my FLI ML6303 camera is out of action I thought I'd use some of my accumulated credits with iTelescope. The attached was abtained this morning from T21, New Mexico. It shows the tail and the spline nicely.

I am always frustrated by the really poor calibration that iTel do on their frames. This camera is the same as mine but it seems to have horrible column defects that are not being calibrated out correctly. There are loads of hot pixels in the subframes too. Somewhere I have some software routines to clean these up but I have never had to use them with my camera.
