Probably anyone who has taken a look at that photograph (presumably including the photographer himself) must have seen the blue (O-III) bubble to the left of the large-area part of VMT 10, around the three stars HD 48099, HD 47756, and HD 47984. However, it was formally discovered in April 2021 and now it is called PaRasMoMi 1 (Patchick-Rasool-Mohan-Mishra 1):
There is a curved filament, which looks relatively bright in O-III on the cloudynights image. Has anyone of you observed (or tried to observe) this filament (or anything else of PaRasMoMi 1)?
I tried on Tuesday this week, but did not succeed, with my 20" Dobsonian at 128x - 256x with an O-III filter.
On the same occasion, I was able to see the brightest part of VMT 10 on its eastern side, but unable to see SNR G206.9+2.3
I got the brightest part of VMT 10 together with Martin Schoenball with his 10-inch in 2005 under very good transparency.
Last year I tried VMT 10 with my 4" binocular telescope. With [OIII] I could spot the brightest part in the east as a very faint edge.
After that and after my first observation in your mentioned thread I revisited the whole complex with my 27-inch and again only saw the prominent eastern part as a good defined edge of a slight bend arc with 113x and [OIII].
I also tried the inner [OIII] arc which is now called PaRasMoMi 1 but also had no success in seeing anything of it.
Thanks for your reply! And for confirming that this nebula complex is really difficult to observe visually! So this recently discovered nebula does not seem to be a visual target at all.
