Description
Another view of the Great Hunter`s NebulaAnyone who looked at my last image will see this one is significantly different. What you see is elemental Hydrogen, Oxygen & the very rare doubly ionized Oxygen.
I was using an Orion Oxygen III narrow band-pass filter. This allows passage of 90% of the light at 496nm and 501nm emitted by extremely faint diffuse nebulae. This also significantly decreases the overall light meaning an equal increase the number of exposures in the stack.
This is 460 frames, 1 hour and 40 mins total exposure time,
Stacked in DeepSky Stacker, Levels&curves& slight CC in CS5.
My best thoughts, wishes and prayers for the future to all my dA friends!

Thanks so much for the support, comments, 
The colder weather isn't the most co-operative for continuing observations...
not that I have much time right now with the other info thundering through my head.
LOL! it doesn't leave much room for anything else.
May this year bring you Great Blessings!
The Future can be bright!

I guess I just assumed you would collect all those photons in a single exposure. But of course that wouldn't work. The electrons would leak off the CCD much too fast.
So I gotta ask, what ASA do you use? You can crank the ASA up to the max, and then let the noise get hammered back down in the stacking process. Or accumulate much weaker pixel info at a lower ASA and just sum them up during stacking. But it's not clear to me which would be better.

Non polar aligned mount means a max of 10 sec exposures.
Since the OIII blocks out all the other light, I cranked the ISO up to 6400.
Best SNR ISO (different for each camera) for longest duration & stack. If you really want the best results though, you need to take Darks, Flats & Bias frames as well.

Oh! I just assumed you had a polar mount. I didnt know there was any way to take pictures like this without it.
