A different view on Messier 43

Hello everybody!!!
It has been quite a while since I have been posting the last time... I haven't done much astronomy in the last 3 years, but now, I what to start up again. I started last autumn with an observation project which involves a few techniques that I have already been showing here:
https://www.deepskyforum.com/showthr...rameter-of-M-1
and
https://www.deepskyforum.com/showthr...-27-in-bicolor .

Now, I also observed with color filters as they are used in planet observations to create a "classic" rGB composite. The "r" is written small, since it is only a pseudo-red channel. I used a yellow filter, but encoded the resulting sketch as a "red".

This is the rGB-composite:

The stacked image with [OIII]- and H-beta filter, respectively:
Attachment 5451

And again, Stokes-Parameter:
Attachment 5450
and max. polarization angle:
Attachment 5452

This time, I used a 8"-SC for polarization observations without any prism to have a rotationally symmetrical beam path, since reflections under a certain angle have a major impact on the polarization state of the incomming light. I am not sure, if I can do so for other objects. In case of M1, I had really problems with this set up because the polarization filter holds back a huge amount of light...

Best regards from Germany + CS
