UT. Unguided exposures after training the mount to follow the comet.
This is my first RGB image of a comet. I am not that pleased with it and I think I made several mistakes.
1. Using the Hutech LPR filter cut down the signal.
2. The wide field of view coupled with a large number of exposures led to star trails that crossed each other, even though enough time was left between exposures to produce "dotted" trails, this led to artifacts in the SD mask combined images.
3. the low signal in the tail meant that the stretch required to show it also showed the artifacts from the star trails.
I will try again without the LPR filter and use an IR blocker instead. Hopefully this will allow shorter exposures or get a better signal.
