Unmodified DSLR and filters
Hello, I would like to get advice about using filters with unmod Canon 1000D. I would like to improve my nebula shots and have looked through previous threads but still am not sure if purchase of UHC would be the first filter to get (either clip on or 1.25" in filter wheel) I have a H alpha filter I haven't used on the DSLR yet but I believe it probably won't work particularly well on an unmodded ? is this right?
What about O III filters and ummodded DSLRS?
I have 80/100mm refractors and one 8" SCT plus a mono CCD.
Thanks for the help
Graham
