his image of course shows way more detail generally (and in the core, which if anything is brighter than what I have presented), but then he has 20x the integration that I do, and with a mono sensor |
I probably shouldn’t have called it an artifact
Processing techniques , saturation , brightness, integration etc… may expose this circular structure around the core region ?
Here’s my effort this year with my mono set up and last year with my OSC set up
I tend to be light on saturation and brightness
All subjective of course
