Willow Springs DeepSkyRanch Sat 2-9-2013 Deep Sky Observing In On A Deep Freeze Winter Night
Observers: Kevin Ritchel, Steve Gottlieb, Richard Navarrete, myself (Mark Johnston)
Conditions: Sqm generally around 21.5 with 6.6 NELM or better. Transparency 5/5 with seeing 4/5
Temperatures were from 32F down to 26deg F with rare, light winds.
Equipment: 18" f/3.7 StarMaster, some views in Steve Gottlieb's 24" f/3.7 StarStructure (Thanks Steve)

8:11pm 6mmDe 324x A faint evenly illuminated glow 30" in observable size 1.3EL at perhaps 70dPA. a 1/6fov [2.1'] 5-star elongated pentagon 'Auriga like' pattern encloses Maffei I where the 'top' was up in my view or west. The glow had non distinct edges and was detectable averted in moments of good seeing that would last 2-5 seconds. The glow that I could count on was around 1/2 of the space between the bottom right and mid-right stars of the Auriga-like pattern [26" or 1/2 of 52.6"]. The 6mm Delos in the Paracorr had much better contrast than 8mm Delos.

9:00pm 6mmDe 324x With north at 11pm we see a mostly EW pair of bright stars that mostly bracket the main glow [these stars are GSC 4120:1000 to the east (left) and GSC 4120:764 to the west for 3.6' main core size] I describe a bright area of glow above the east bracketing star by 1/3 spacing of star-pair [1.2']. This is non-stellar. [This is Ngc2404 it seems]. There is darkening below and to the right then an arm glows stronger below and to right of main core. SW 1/4 fov below east star is a field star [GSC 4120:703] and just to it's right is a glowing area that is distinct but I don't have a designation. Another distinct glow is in 4pm direction from right bracket-star 1/2 spacing of bracketing stars [1.8']. Also off of right bracket star we go upwards to 1pm 5/8 space of bracket stars [2.25'] [This was found to be VS 3]. Going east by about the bracket-star spacing [3.6'] we see another bright area. [I believe this is VS 24] The brightest part of the central section is fairly uniform and 4/10 of bracket star space [1.45'] dia. This main glow has on it's lower [S] side an obvious foreground star that is itself 4/10 [1.45'] of the space starting from left bracket-star to the right but is just above the connecting line. [Ucac3 312:46991]. Inspired by Steve Gottlieb March 2013 S&T article but I had not brought the chart from the piece so just noted what I was seeing and missed one but saw two other bright areas not discussed in the article.

9:15pm 6mmDe 324x 1/4fov [3.3'] 3EL appearing as a faint diffuse glow. A faint field star is just to right of the core [SkyX says mag 15.7] With N about 10:30 we see an equal mag triangulum 2.5el tri pointing down and to left at 45deg or roughly east [1.8' in len] Length of 2366 is 1.3x len of tri [2.3'] with a very bright glow on the far right side or SW side. The bright H2 region has fuzzy appearance with stellar point and seems very slightly elongated close to EW.

9:15pm 6mmDe 324x We can detect a stellar point that we can hold for 2-3 sec at a time. If in this view where N is 10:30pm we start at the H2 region in lower right of Ngc2366 and go up [NNW] by 4/10 of the way [3.3'] from the H2 to the rightmost 'triangulum star' [GSC 4360:918] we find a dim field star [4/10 is 1.3'] Rotate to the right from H2 region 20 degrees and it is here we can see with patient viewing the core of Ngc2363 pop in and out for 2-3 second or longer periods of time. Not other glow noted. I describe this core glow as colinier and half way along a line from the H2 region of Ngc2366 to a lone but dim field star that is twice the radius [6/10 or 2'] out from the H2 region at about 1:30pm or WNW. This farther out FStar is brighter and 100% viewable averted so is brighter than core of 2363. Observation inspired by Steve Gottlieb March 2013 S&T article.

9:30pm 6mmDe 324x 1/8fov obvious glow [1.7'] I describe a 1.3 tall IsoTri that points to 8pm in this view where N is 10pm. In the upper left of the field a broad chevron pointing to 5pm that points towards the smaller tri shape. Glow above and to the right of the Tri structure is very distinct. Movement seems to show far fainter glow off to the left that may extend the full length of the dwarf to be as much as 1/4fov [3.3']. With careful study and time I felt that the dimm glow above and to the left of the small triangle [North of the triangle] is gone by a point that would be defined by an EQ triangle if another star was below the bottom, horizontal, chevron stars [below, SE, and centered between GSC 4377:2375 and GSC 4377:2213]. Observation inspired by Steve Gottlieb March 2013 S&T article. I did not have the article with me so was not aware enough to note the bright knot designated as HSK 45 but did note as a detail that the galaxy itself was the brightest just above the brightest of the tiny triangle stars which is where the knot is supposed to be. I noted another brightening 1' N of this star which also seems to show as a slight brightening in the DSS but nowhere near as bright as HSK 45. A third distinct brighter area was noted to be up and to the right of the triangle by the spacing of the triangle [about 1' W of HSK 45].

A field star that was always visible 20" [to the SW] of the A member made a great reference point. At no time were both A and B seen at the same time.

Because it is twice the spacing away from the field star it could not have just been Hickson 50A again as distance judgement was clear. At no time were both A and B seen at the same time.
