Here is my first Swan Nebula image taken in the same place and time (last night) as my Orion pic. Just a few small stacks unguided with a Canon 40d.

Very nice image considering it is unguided. Keep at it.

Excellent image Steve especially as it was unguided. :)
How long were the exposures?
Well done. :thumbsup:
A nice capture Steve, reminds me of an inferno.
Considering it was unguided and just a few small subs you've done well.
Did you use any noise reduction routines in the post processing stage?

Great first Swan Steve and unguided! (Don't you just hate these unguided shots?) Keep them coming.

Nice work. I long for guiding too but it has its own frustrations by all accounts... keep em comming.

Thanks guys, I think this is one is definitely showing I'm starting to learn the trade and show improvement, and it's great to see that you can see it too!
Here is how I did it: Prime focus Skywatcher 8" Newtonian on EQ6 Pro. 14 * 30 second lights ISO 1000, 1 * 95 second ISO 1000, 2* 70 second ISO 800, 1* 90 second ISO 800, 2* 60 second ISO 800 using a Canon 40d with no on camera noise reduction.
This was all punched into Deep Sky Stacker at the same time also using 9*30 second darks ISO 1000 as well as 9*30 second ISO 800. I used 33 flats just from the whole file, so they would have had a range of ISO from 800 to 1600.
Then processed levels and curves in photoshop with a little unsharp masking. Noise reduction done in Noiseware on factory settings. There was heaps of light pollution around me since there was a street light five meters away.
The mount initially set up with an illuminated reticle eyepiece for polar alignment and when this was achieved i then 3 star aligned the scope (way better than two star).
I'm starting to think that a heap of smaller two minute exposures might be the way for me until i can afford a guide scope. So I'll take some more lights and see what i come up with. STEVE. :)
