Hi,
Lovely photo again
.
I am amazed at the different Ha response from Jases image, (and i understand he has an $11k camera). I thought modded DSLR's would easily pick up dim Ha. Your horsehead and others seem to get heaps of Ha. Is this that much dimmer?
Is it because you can only really go 7 to 10 minutes with an uncooled DSLR or would you get much more under dark skies?
