Thanks chaps
it's early days but so far so good. I can imagine that two cameras are useful, fortunately I invested in a Fuji X-E1 a while back in the interests of science, so I can always resort to that for those where Ha offends
the filter on that one seems to actually let some red through, whereas the Canon previously didn't.
Yeah Rob need to sort the cooling out, it was shockingly hot the other night, must have still been over 20c at midnight
Raymo, yeah the same ISO on both occasions, I use ISO1600 almost exclusively. Then I take the raw and work from there. That's probably where the difference in colour balance comes from.
So there's objects that are more heavy on the red side than M42?
so far I've only taken a few test shots, although I was a bit like a kid in a candy store...Eta Carinae, the Running Chicken, Tarantula, a couple of wide field shots around and along the Milky Way...it was all up for the taking
