There are also a number of papers that reference it there as well so you can get some information about it. Simbad is always a good place to look for this kind of stuff, for galactic objects anyway.

Thanks Owen
Hi Steve if you want to point the thread in that direction then there is the nice YSO atlas and observations by Reiner Vogel at http://www.reinervogel.net/index_e.html

Hello Steve, do you have any information or observing notes on Parsamian 22?
Sorry I didn't respond earlier but I was out of town at a 5-day star party, but I haven't observed Parsamian 22. Have you looked at the SIMBAD entry? You might find a paper that gives some information in the 15 references.Quote:

I took a look at Parsamyan 22 this morning and was really surprised. It was really cool to see its elongated faint ghostly glow embedded in the open star cluster. I am a big fan of two objects in the same field. The YSO was visible as a small pin point yellow star with AV @ 610X. I highly recommend you to give Parsamyan 22 a go.

Awesome! I can’t wait to give it a go this weekend, thanks for the reply . Raul
Hi everybody,
Well this past weekend I took a look at Dolidze 8 the cluster where Parsamian 22 resides, and I believe I caught a glimpse of it. The seeing was not good, probably 4/10, I believe It to be more visible at 75x than at 158x where it seemed to get washed out. I caught a glimpse of what seemed to be two very difuse streaks of light eminating from one of the stars in the cluster. I'm going to look at it again next new moon,to confirm and hopefully sketch it. Raul
I got a look at Parsamian 22 with my 28-inch at the OSP last week. It was quite subtle, but then the sky was full of wildfire smoke at the time so I feel lucky to have seen it at all. It was best seen without any filters at 408x.

"...It was a snap to see it even though it was quite subtle. A short, faint fuzzy streak jumps out with averted vision, looking bigger than in photos. Filters (NPB, OIII, h-beta, broad brand) didn't help at all. 408x, 21.81 smoky SQM. ps - this area has some distinct reflection nebulae - NGC 6914, vdB 131 and 132."
Hi,
Here is what I observed in 2005 about that object in my 17.5" Coulter at 271x (I have NELM of 6.3 and transparent skies) : small, extremely faint (glimpsed less than 5% of the observing time with averted vision), oval, about 35"x15"ENE-WSW, homogeneous with fuzzy edges, no central star and no response to UHC, OIII or Hß filters; located on the SE side of Dolidze 8 which consist of a dozen sparsed stars between mag.10 and 14.

9/26/22 Parsamian 22. At 150x in 16” it was faintly visible as a short, soft, glow. Not going to be visible in 10”, though!
