I just came in from taking some images of Comet Holmes. I am still
using the BVRI photometric filters. It is extremely bright in the
longer wavelengths. Just a 30 second exposure in the R band saturates
the image. It is now filling the frame nearly completely with my DSI
Pro and 12" ST @ F/3.3. That is one big fella.
I plan to post the new images once I get done and also new 3D
profiles. The profiles are good because they are independent of any
brightness or contrast setting. They created from a pixel map
directly from the FITS image.
Back to the telescope.
