Great find on the Celt! They're hard to find and that's a beauty. This is definately the midsection of an Archaic point. It could be any of the types you've listed. If I were to guess I'd say it's a Decatur, but without more to it it'll be tough to ID. Great day though and good luck in deer season.
As far as the no camera, no in-situ goes I had a similar experience once. I moved here last spring and the first field I hunted was after work and it was getting dark. The very first piece I found was a tri-notched Cahokia. I was probably 200 yards from the truck which had my camera in it and I wasn't confident that in the failing light and a field I wasn't familiar with that I'd be able to go get the camera and return to get a pic. So I cracked under the pressure, picked up the point and didn't get this in-situ. It's hard enough to let a good piece lay while you take an in-situ. It's a great question for the group, what's the longest distance (or time) you've ever let a point lay so that you could get a picture or show a hunting partner? I usually will put my hat over a point and let my hunting partners see it in-situ.
