Thanks.
Justin, yeah, I realise I need a modded DSLR for the red H alpha. I can't do that to this one as I need it for other purposes. I'm saving pennies for a CCD setup.
I've been fiddling in StarTools beta today (even on my new laptop, it's slow - I think the image size is too large and I need more RAM). I think, if I knew what I was doing I could extract something better. But that's not today.
