Hi Mark,
Every imaging system is different. This is why the calculations are necessary and helpful. The image scale, detector QE, filter, and the amount of light pollution for you location are critical factors, just to name a few. Without knowing the details I can't begin to answer your question. On the other hand, the integrated magnitude alone tells us very little about the target object, especially when it is an emission line object like a supernova remnant.
There is always the possibility that you have something set up incorrectly, but again, I would have to know about your setup in order to provide any insight at all.
Have you actually imaged M1 and estimated the SNR?
