Update: Final uses latest PixInsight update & my new iMac 4GHz, Retinal 5K. I think it is a significant improvement. :-)

I noticed that IC 360 is considered a bright nebula (https://www.astroleague.org/files/u3/BrightNebulaRev2.pdf) of 180' in size in Taurus but never saw examples of it in Astrobin. So I decided to explore this region (in this 2-panel mosaic).

As a side note, the blue reflected nebula is Lynds 782 (on left embedded in dark nebula).

Getting back to my confusion and discovery, referencing: http://cseligman.com/text/atlas/ic3a.htm#ic360 , it states that...

"IC 360

Discovered (Dec 6, 1893) by Edward Barnard

A lost object in Taurus (position essentially unknown)

or perhaps an emission nebula near RA 04 05, Dec +25.7

Per Dreyer, IC 341 (Barnard [A.N.](#3253), 1860 RA 04 06±, NPD 64 20±) is "very faint, most extremely large, very diffuse" (#3253 refers to a note and finding chart published by Barnard in the Astronomische Nachricten of that number; unfortunately the finding chart does not show the nebulosities, just stars and a coordinate grid, but a later publication, partially reproduced below, does show many of the nebulosities; also see the IC2 note above the entry for IC 336).

Per Corwin, this is one of several extremely faint diffuse emission and reflection nebulae attributed to Barnard in this region, including IC 336, 341, 353, 354 and 360, but although Barnard did the sketch showing the nebulae, Dreyer chose which ones to add to the IC, and estimated their position from Barnard's finding chart and sketch. Some of the IC objects correspond to obvious smudges on Barnard's sketch, but others do not, so it is hard to understand Dreyer's choices.

The case of IC 360 is particularly puzzling, as Dreyer's position (J2000 RA 04 14.5, Dec +26.0) is well to the east of the region sketched by Barnard, so he presumably meant to record a completely different position. Under these circumstances, it is probably best to treat IC 360 as lost, but we can essay a guess at Dreyer's intentions by supposing that his declination is more or less correct, and choosing one of the easternmost smudges on Barnard's sketch. That places us on the smudge to the southeast of a line of three stars, as shown by the label "IC 360" on a copy of Barnard's sketch, below.

The position shown above is the brightest portion of the nebula thereby indicated, and is used for the center of the image below. Whether the nebulosity thus identified is actually IC 360 is another matter. I wouldn't place any great confidence in the identification, but since every other identification I've seen corresponds to a region outside Barnard's sketch, it is presumably no better or worse than any other guess (which is more or less equivalent to saying that the object is lost). "

Check out the drawing of this region in the above reference to get an idea about the discussion above.

Anyway, near the 7-Sisters, it is worth exploring. I will revisit to expand and improve on this original, weather permitting.

Final is just another version with more enhanced nebulosity and changed orientation.
