TYC 2464-1041-1 nebula?

[Ivan Maly]

What's this around TYC 2464-1041-1 in Aur at 07:28:26.79 +36:57:43.4? A little blue fuzz immediately around the star is visual in 12" at 250-400x and the eastern branch segment is inconclusive. Maybe the whole thing is a plate defect though.

Am I using this wrong, because I don't see anything in any of the DSS images accessible here:
https://archive.stsci.edu/cgi-bin/ds...esolver=SIMBAD
I thought what you shared is just a color-composite made from some of these.
Am I missing something?

Yep, that's DSS on Aladin, as all would be able to read imprinted on the image, had we resolved that issue with resolution on this site. I am aware that this seems to be the only place that shows it, but it's hard to believe Aladin would make its own plate scans.

It's an artefact, a pretty nice one actually ;-)

It's visible only on a POSSII Blue plate taken on 22 November 1987, available at http://archive.stsci.edu/cgi-bin/dss_plate_finder. Just enter "TYC2464-01041-1" and select to display or save the fifth plate.

Cool. Thanks! Filaments do occur on plates, this one (assuming it is indeed a filament) was just so intricately and "cosmically" folded, it was hard to believe.

Keep looking, plenty of treasures remain hidden in those images! If you run into anything undesignated post here (of course ;-) but do stop by the DeepSkyHunters Yahoo Group https://groups.yahoo.com/neo/groups/deepskyhunters/info

Earlier this year, I was able to confirm this one: http://archive.stsci.edu/cgi-bin/dss...e&fov=NONE&v3=
The faint nebulosity surrounding Psi Virginis could not be confimed by other images, so I gave it a try using no more than my 14" SCT and a Canon 6D. It's faint but it's real: https://www.dropbox.com/s/c0hjfiztbk..._VAvW.jpg?dl=0
The little kidney-shaped piece SE of the star is most obvious and faint nebulosity is present to the NNE, too. That, or I managed to perfectly reproduce an artefact.
