We had two clear nights in a row and I had the opportunity to continue to explore differnt exposure times, processing techniques and imaging systems for Comet Hale-Bopp. I used a SBIG ST-6 with either a 12 inch Meade LX200 telescope at f/4 with a red UBVRI filter or a f/5.6 60 mm telephoto lens unfiltered. I used the following exposure times and processing techniques using SBIG CCDOPS software:
