Hi, I've been trying to get M76 for a few days now using OSC ASI533. I tried several exposures and with no filter & with Optolong L-eXtreme LPF filter. The problem is that every preliminary processing of the images showing a different structure than that I've seen online and in books. Other pictures show the M76 with a central disk and opaque periphery. My pictures are the opposite, opaque center and dense periphery.

Does someone have an explanation or can tell me what I'm doing wrong?

PS: Please excuse my pictures quality as I didn't complete my capture or processing yet...
