I took the liberty of examining the red channel where it shows up quite prominently and have attached a crop with a stroke around what caught my eye.

Fabulous image, mate.

Thanks H And thanks for taking the time to investigate. I hadn't thought of checking the red channel, but I can see clearly what you mean.
Yes it might be a glimpse of the tertiary shell which indeed does exist. I can't say for sure however if it's not just the remnant of the glare from Eta (which did show prominently in the raw images). It still has to be said that a lot of processing has gone into this image so these tiny subtleties could be real or not. But it does correspond roughly to the extent of the tertiary shell, so maybe...

Thank you very much Ken. Yes, TouCams are surprisingly good, I'm glad I modded mine back then 8 years ago

Amazing what a web cam can pick up Rolf

Thank you for confirming Mike, yes it really does looke like it. I'll get some more data some day and then maybe it'll show up better. In either case I can't be unhappy with 2 out of 3 shells though

Gold star & an elephant stamp for that effort.
Thank you Justin It's nice to be able to do these things even with such a basic camera. Such small and bright targets are where webcams have their force.
