Hi All,

From the usually cloudy Melbourne, a rare night of clarity.

I have finally got my new gear mostly sorted, just in time to try to capture comet Lemmon. Taken with an ASA N12, Sbig STT8300 combination. Over the past few nights I've been taking photos of this comet, but I keep getting trailing in RA, this is still present. I've worked out (after a few consultations with the internet) that guiding near the pole is not a simple task. Also I have shifted over to a Mac for telescope and camera control using The Sky X and the camera add-on, this has introduced a few complications (like timeouts for the CFW which stop the imaging sequence) and having to setup the colour series differently to drop the stars from the image.

Anyway, here's the picture, 30 mins Luminance (10 x 3 min), 10 each for RGB (10 x 1 min, binned 2x2). Processed in CCDStack2 and Photoshop.

Cheers
Stuart

P.S. Added an image with stars, you can see the guiding errors in this image.
