Tried the Horsehead with the Canon, last night. Everything went ok setting up etc. Did 25x300, & it is complete rubbish.
Gradients, amp glow, vertical banding, you name it, I got it! I cannot bring out any detail. I think I should not have used the Focal Reducer, as the HH is too small. Next door made a cup of coffee & then left 75 lights on the rest of the night. The sky was very light, & Orion was heading in the direction of the Moon & next door's kitchen.
Afterwards went to Rosette, it was in very good focus & sky area was not quite so light. I only got 3x300 before clouds rolled in. I stacked the 3 with darks, flats etc & it would have been a better image than the HH. I could not do more than 300secs & the subs were a very light pink anyway. I know 300s is not long enough for nebulae.
Thanks for your help, Chris.

I added another 20X 5mins to the Jelly - I now have something like 50 frames... My longest image ever... Will try & process later...
I just restacked HH. It came out a bit better, better than first time & not so long. It is still nothing to wrote home about. I have used noels actions etc. I think it is too small, using fr & too noisy, but sky was very light. Hope your jellyfish is much improved, although it was good anyway. At least Gemini was in a better position for imaging.
Agreed, conditions were not at all good last night. I also tried to get some Horsehead data using the Canon and the CLS filter. I got 30 frames before the clouds rolled in but they are very noisy - in fact I can't even see the HH on each sub - it is drowned out by the background :-(

your all nuts, I went out froze, thought sod it the skies were only mag3 anyway, came in and watched a file, your mad!
I think you'd be better off watching a film or television Chris !
I live a boring life...
I'm glad about that, Mark, I thought it was me!!
I had a crap night too, took the gear out, set up, tried to align and was stopped by my RA grinding to a halt every time it went through the 6 O'clock position, so had to give up and looks like I'll be sending it off to be repaired!
That said, Chris's comment that the skies were only mag 3 made me chuckle, my limiting magnitude here is about 3.4 on a perfect night at zenith.
Daniel
:O)
Oh, hope you get that fixed quick, Daniel. So all in all a bad night was had by everyone.....................except Chris :lol:

Whats the mount Daniel?
Also 3.4, that would be nice when the gym lights are on :-) but 3.4 without lights wow you must have really bad pollution.
Hi Chris, my mount is a CGE (which turns out is a pain in the arse to get serviced)
On a perfect night I can just about make out the dimmest star in cassiopaea with averted vision which is about mag 3.39!
Daniel
:O)
wow how does that mount carry that scope, and wow thats light pollution!
