Good luck with the camera mate.. I hope you enjoy it like I did!

Thanks for your suggestions Alex, I will indeed invest in a Ha filter and have a go at this again. The Horsehead is one of those icons you must have a go at. I promised myself this when I first started last year but was disappointed with the DSLR shots. This is a totally different kettle of fish but the first result I find very encouraging. Oh, so many targets, so little time.....

Consider trying a high dynamic range layering to get both to work out. |
Thanks for the suggestion Paul, this was only a trial with the camera, but yes Alnitak is a bit of a monster and hard to process around. I will come back to it after I get a Ha filter as Alex suggests. I'm not familiar with the HDR layering but I'll have a read up on it before I have another go.
David, I used a SW ED100 (old blue tube one) F9 mounted on an LXD75 guided with a 100 mm F6 achro/DSI pro combo and PHD. Took 25 subs but only used 19 as DEC was bouncing around occasionally.
