Is M33 Really in there? :)

I used levels and curves in PS but keep on starting over. I can see hints of the galaxy, but can't seem to bring it out. I would LOVE to see what it would look like from someone who knows how to extract the data!
Here is the 32bit Tif from DSS if anyone wants to show me

1) Not centered.
2) Vignetting - you didn't specify telescope and camera so not sure what can be done here.
3) The need for calibration frames (darks, flats, etc.)

I messed w/ it a bit too after doing some cropping, DBE (which didn't remove much other than the vignetting), stretch and bit of curves. Got pretty much the same.
Dann, what sky map are you using? Before I start my imaging, I use the live view if I have stars visible and identify where I'm at the center. If I don't have any stars visible, I just try to take as short exposure as possible with the ISO cranked. This way I can assure I'm not cutting anything off that I don't have to.
I'm not sure it'd save you in this image, but something to keep in mind.
I know you're in a heavier LP zone than I am but all I can suggest to help would be to try and get that histogram between 1 and 2/3. I think you can probably go all the way up to half and capture the finer details while also being able to not completely overexpose. The LP can come out in processing.
Looks like your auto guider really is working out for you! Glad to see that (feels good, doesn't it ). I don't think you need to toss this data. Maybe someone more experienced would disagree. But try to center it better and put a couple more hours worth of data on it. If you can do that I'd imagine you'll get much more pop out of it.

Tim... I used ISO 200 since I was taking 240 second exposures... I didnt even check the damn histogram in BYEOS! I am pretty happy with my first attempt at guiding... It wasn't perfect but is was very windy too! I may try again tonight since our fine members of congress have given me a vacation
Jim, Thanks for the input... I need to learn how to take flats... That is on my list of things to learn!

Regarding flats, put your camera on AV and switch BYEOS to AV-Flat. If you don't have a light box yet just point it towards the sky during twilight. I've been doing that and had mixed results (bad results when I wait too late). I won't say it's perfect but I many people do and you can run them off while you're setting up. Doesn't take too long.
