Comet 1999T1 McNaught-Hartley

It took quite a while before I could take an image of this comet: bad weather, a full moon, family matters, work... only on 15 February I managed to capture C/1999T1 on my ST8+CFW8 CCD chip. The LRGB image was made between 03:30 and 05:00 UT and consists of 10 images, including a RGB set. All unbinned images were exposed for 5 minutes at -20°C chip temperature, but the blue image got 10 minutes exposure. The telescope was a Takahashi CN212 in newtonian f/3.9 configuration.

My FS2 GoTo drive controller was programmed to compensate for the comet's movement in relation to the stars, no other guiding corrections were made. The images were taken with SBIG CCDOPS W95, processing was in AstroArt. There was a last quarter Moon and some haze. North is up, East to the left. The image size is about 55 x 37 arcminutes.
