Tonight might be clear and I'm setting up with the C11/hyperstar to do some deep shots see if I can pick up comet ISON. My problem is light pollution. I'll be shooting with the QHY9 mono. Is there any kind of dense filter that I can use to minimise that? I have Baader Nebulae filters, RGB set, UV/IR block, etc...
Ha is out of the question I suppose. Would it turn up in Oiii? Just thinking aloud here. What would work for that comet. What is it made out of? Anything that will stop me from taking flat frames. It's pretty bad LP.
TIA for any pointer.
