Good night with the 6-inch, average seeing but good enough for this scope.  Took far too long to do star alignment but once dialed in had easy finding.  Wasps were congregating in the pier support, so I sprayed them.  At the end of the night I noticed a very large wolf spider had somehow created a web from the telescope to a nearby bush -- I sprayed that too.  'Tis the season and I'll need to take a careful look for them as I handle the scope.

7 october 2023

Tried to get the 20-inch back up and running last night, having upgraded the ServoCAT from Gen 2 to Gen 3.  I have it mostly working, with goto functioning.  Tracking is still not good, and goto not very accurate.  And I could not get the laptop to wirelessly connect to the Nexus.  I'll give it some more tries to make everything work -- I can always revert to Gen 2 if needed.

Seeing was good and I tried a couple of "movement" list doubles, punching in the coordinates and pushing to them.  Saturn looked nice through the 20-inch but to be honest, it looked better through my 6-inch refractor, which I had also set-up as a backup.  The contrast gain was significant, it wasn't so washed out an it looked solid, like a 3D physical object.  On to the 8-inch refractor, I think.

BU 1129 AB: 508; 1060x: Light orange stars, slightly notched, PA seems to the NW but is difficult.  SOC grade 3 orbit, 121.7-year period, it will hang at this PA and separation into the 2040s.

29 august 2023 Cepheus Struves

Another clear, if hazy, night, with average to good seeing.  I used the 6-inch on Cepheus Struves, and had a surprisingly good night.  I didn't cover the entire constellation, but did get a good chunk of it.  Viewed the moon and Saturn at the end of the night, but transparency was hurt by Oregon wildfire smoke which has blown down our way.

more obscure nebula

Reviewing the Finkbeiner layer in Aladin, I noticed two relatively small clouds located off the plane of the Milky Way. One is in Hercules near planetary nebula NGC 6120, and the other is near Alpha Aquarius. I've yet to figure out if there is a designation for these but decided to try for them the next opportunity I had.

I observed Friday night 9/8 on top of a ridge in the California Central Coastal Range. Transparency was off and a weather system churned over the Pacific; indeed, there were lightning flashes beyond the coastal hills, and some cloud bands streamed slowly from the southeast to the northwest. SQML was 21.09, and I tried to make the most of the night before the clouds came in.

I used both a NP-101 and a 60mm f/6 refractor for the observations. It turns out both of these were best seen with just the 60mm & Ha filter (3nm in this case). I printed star field finder charts and images from Aladin, adjusting the pixel scale to exaggerate the nebula brightness.

The Hercules nebula was very faint, but immediately seen when flipping from unfiltered to Ha filter in my filter wheel. It lay west of a distinctive "U" shaped asterism of 5 stars. The brightest section overlay an elongated triangle of near equal stars, and fainter grey-scale changes to the background sky extended down to a large trapezium asterism. It is around 1.8-degrees E-W and 1.4-degrees N-S.

The Alpha Aquarius nebula was considerably fainter, larger, and more tenuous. I called it very extremely faint, and I couldn't see it without flipping between filtered and unfiltered several times and panning the scope around to make sure it moved with the sky and not the scope. It is very diffuse, no visible edge, and feels mottled. It is around 4-degrees NW-SE by 2.5-degrees NE-SW. I only saw the main body of the nebula; the Finkbeiner image shows a parenthesis of nebula around this, but I did not see these.

I continued through the night observing various LBN objects in Aquila, with the NP-101, many of which rivaled these two nebula for faintness. Having mostly finished observing the Sharpless Catalog, I plan to make the LBN my next project.

Strottner-Drechsler-Sainty 1: 60mm, Ha+OIII dual band, OIII cloud near M31: This was surprisingly easy with the wide field!  Very faint, but obvious, elongated cloud around 2-degrees SE of the galaxy, running parallel to it and bordered on one side by a lazy "L" asterism, the brightest star of which is Upsilon Andromedae.  Discovery image attached, it is the blue-green elongated cloud. 

LBN 92: LBN 030.54+00.41 = Sh2-66: With the 4-inch and Ha, It was faint, irregularly round, diffuse edge, with several bright stars intermingled with one near the center.

LBN-94: LBN 030.66-00.65 = Sh2-67: In the same FOV, it is slightly larger and more oval shape, more diffuse, also with a centrally located star.

LBN 99: LBN 032.38+01.93 -- HII Region = Sh2-69: Faint, small in this field, with a small concentrated mass with a wing or comma shape coming off the northern end and swinging east.  

LBN 100: LBN 032.44-15.40 -- HII Region: 40'x12': Large, 3:1 oval shape, with many stars intermingled, moderately brighter in the middle.  This seems to be one part of a larger structure, which I did not see as I did not pan around.  

LBN 101: LBN 033.83-14.72 -- HII Region. 180'x90': Large, very faint mottled greyscale change filling the field, seems centered on a large loose cluster of faint stars.

LBN 103 = SH 2-71 -- Planetary Nebula: Small, round, hazy ball with soft edges, brightens with averted vision.  Not enough image scale to see the detail shown in photographs.  

LBN 104 LBN 036.57-01.81 -- HII Region = Sh2-72: In the same field, appears as a curved glow, diffuse and large.  The image here from stellarscenes.net shows LBN 103 as the bright red glow near center, and LBN 104 as the red diffuse glow just left of center.  

LBN 108: LBN 039.55-16.65 -- HII Region. 150'x50': Very large, fills the 4-degree field, very faint and vague but with noticeable, if diffuse, edges.  

LBN 110: LBN 040.46+02.46 -- HII Region: Sh2-76: Extremely weak oval glow, between two equal magnitude faint stars

LBN 111: LBN 041.37-18.83 -- Molecular Cloud.  Pretty large, extremely faint, irregular shape, in a box of stars.  

LBN 113: LBN 041.84-18.59 -- HII Region 70'x20': Faint but easily seen, large, area full of mottled nebula.  Can't find a good picture!

LBN 114: LBN 042.59-23.34 -- HII Region. 85'x30'.  Very faint, large, elongated through a field of bright stars.  Another I can't find a good image of.

LBN 115: LBN 042.75-21.54 -- HII Region:  35'x10', Fairly large, very faint, no clean edge.  No good image.

LBN 116: LBN 042.97-17.43 -- HII Region: 140'x80'.  2:1 elongated large cloud, faint, faintly mottled, soft edges.

LBN 119: LBN 043.64-21.66 -- HII Region: 140'x10'.  Long, thin faint stream of nebulosity, fills most of the field.

LBN 120: LBN 043.96-23.21 -- HII Region:  30'x35' Large, nearly round, with diffuse edges, in a large triangle of stars.  

LBN 122: LBN 044.95-20.39 -- HII Region: 42'x12': Large, diffuse, faint elongated nebula appears to be mingled with a large loose open cluster of faint stars.  

LBN 123: LBN 045.51-20.67 -- HII Region: In the same field, just above LBN 123, it is smaller, rounder, and a bit brighter.  

LBN 124: LBN 045.60-22.06 -- HII Region:  Fairly large, faint.  

LBN 125: LBN 046.20-21.45 -- HII Region:  Elongated faint nebula, fairly distinct edges.

27 august 2023 Delphinus Struves

After several weeks of non-observing due to clouds and generally poor conditions, it was clear enough last night to observe with the 6-inch.  A dozen wasps flew from under the tarp as I was removing it, so I looked around to see if a nest was being built -- I didn't see anything but hopefully there's not one in the mount.  There was a haze around the low waxing gibbous moon, so I had a look at it from around 8:20-9:00pm.  I noticed three very bright reflective mountain tops in the area of Schroter's Valley: the brightest was Mons Herodotus and there were two other peaks, closely separated, between it and Montes Agricola (which was not visible).  They were bright and compact enough to do a star test.  Seeing was not great but I was able to carry magnification to 200x.  The addition of filters helped my eyes but seemed to rob me of detail.  I was able to see four craterlets in Plato, through it was a couple days past best lighting.

I proceeded to observe the Struves in Delphinus, and completed the whole list in one go, closing up at around 10:40pm.

12 july 2023

Since seeing was predicted to be only average, I used the 6-inch last night.  I started out in Hercules but everything was too near zenith, and Byers 812 doesn't play nice with long refractors pointed at zenith.  So I moved up to Draco and covered a lot of ground there.  Seeing became quite good after 10pm, at least for the small aperture.  I had great views of some pairs with the 60mm, perfect stars.  Anything I can split at low power with the 6-inch I can split at high power with the 60mm.  I'm so happy I added it.

STF2107 AB: 152; 200x: Delicate pair, split, faint, 2Dm, delta faint, suspected double at 125x.  only 2% PRO, but a 92 AU WS, 1.6+1.1 Msol, and SOC has a grade 2 orbit 274-year period, tightening slightly to the SE in the next 30 years.
