7 october 2025

Nice night with the 6-inch, good transparency and seeing.  I continued through the red star list, which I'm enjoying quite a lot:

19 Psc: yellow-orange 

47 Cap: pretty light orange  

7 Cet: bright light yellow 

77 Peg: yellow 

AC    1 AB: Rusty yellow A and much fainter B emerges beyond first diffraction, with seeing.  SOC grade 4 orbit, 525-year period, currently at periastron.

6 october 2025

Observed with the 20-inch for only a little while before I had an azimuth encoder error and had to end the session.  I'll need to tear down the scope to get at it (I hope it's as simple as a loose set screw).  That's probably a good thing as I can clean the structure and give it some maintenance.

Seeing and transparency were ok, with a nearly full moon.  I observed from the red star list, all of these at 140x:

BLL  41: gorgeous deep orange in a very rich field. 

BLL  42: deep orange 

BLL  43: striking, bright deep orange. 

HD 227112 yellow-orange, close to a bright light-yellow star

V2093 Cyg bright yellow-orange in a rich field 

WEB   9: striking group: orange and blue unequal wide pair, like Albeiro, with a third fainter pale blue star in an arc, and a wider, brighter blue-white star below the arc.  The primary star is a 0.4" unequal pair, did not try for it.

 

26 september 2025

A nice night with the 6-inch, though transparency was off -- as were my DSC.  Somehow it was giving me grossly incorrect push to directions.  I needed to re-align a couple of times during the night.

The best view was at the end of the session, around 10:30pm, when I used my Bino viewer on Saturn.  I'm not convinced it was due to the binocular summation factor, but I did see all five of Saturn's brightest moons, even though three of them were quite close to the rings.  Tethys and Enceladus were so close together they looked like a double star, and Rhea was hanging from the tip of the ring.  The moons were very small, very faint, and flashed to view with more time observing.  The rings are still nearly edge-on, and the banding on the disk was subtle -- though both poles appears somewhat flattened.

  

I continued observing the red star list:

AQ And light orange-red, low power shows the color best 

BLL   2A very subtly orange, brief impression of color when first look but it becomes bland with more observation

BUP   1A faint deep orange, richer color with lower power 

H 4  66A faintly orange wide faint B 

HD 232372 faintly reddish 

HD 7734 off white or slightly yellow 

HD 8701 golden, very pretty

HR 237 light orange

V466 Cas, bright light yellow, with a slightly fainter wide companion nearby.  These are the "eyes" of the Owl Cluster NGC 457, which was in the field -- though did not make a strong Owl-shaped impression, likely because many fainter members were not visible due to light pollution.

Z  Psc nice medium orange 

21 september 2025

Spent the night with the 20-inch, with average transparency and seeing.  I cleaned the mirror beforehand as it has been many weeks since I've used the scope.  I observed a couple doubles but I've tapped out the CDSA list, and the seeing wasn't good enough to observe movement pairs.  I was left to observe stars off the red color star list.  A nice night all the same.

STF2367 AB: 508; 560x: Light orange stars, suspected double with lower power, good clean split with 560x, 1 Dm, PA to the NE, with wide AB-C to the south.  No Gaia parallax data for A.  SOC grade 2 orbit, 92.2-year period, it is approaching periastron and will hang near its current position for the next 20 years.

18h 41m 16.36s +30° 17' 40.9" P.A. 71.00 sep 0.4 mag 7.70,8.03 Sp G3IV dist. 136.05 pc (443.8 l.y.)

STF2431 A 178; 140x: Wide 3 Dm.  This was on the red star list.  The primary is not particularly red, the faint companion is slightly so. 30% PRO, 6,475 AU WS, 4.3+1.9 Msol, 0.08 PMV, it is possibly binary and an orbit can be tried.

18h 58m 46.59s +40° 40' 45.1" P.A. 236.00 sep 19.0 mag 6.17,9.61 Sp B3V dist. 300.3 pc (979.58 l.y.)

not just for nebula anymore

The star party I planned to attend later this week is being disrupted by the remnants of a tropical storm, with risks of showers and thunderstorms.  Tuesday night (the 16th) seemed the only night I could get away for a darker sky, but being a weekday meant fighting traffic in all directions.  I ended up going to Henry Coe as it's relatively close.

I have been working to recover the 8-inch folded refractor I bought almost a year ago and have made some progress (correcting a flipped objective, adjusting the flat mirror height to spec.) but it still does not provide good clean images.  So instead of bringing it out, I brought my C8, intending to use it in prime focus mode to view star clusters and galaxies.  With prime focus in the C8 I have 78x magnification and 0.5-degree field of view (I couldn't reach focus with my corrector, I need to try a different diagonal).  Unfiltered the whole night.  It fit the night pretty well, and I had been meaning to try out this combination for several months anyway.  Since the Milky Way is slipping into the western sky, and the west is completely washed out at Henry Coe by light pollution, it was no night to try nebula.  The C8 was the best choice, and I'm glad I got to know its capabilities with night vision.

I was the first in the lot and Richard and Philip arrived at sunset.  Richard with a 5-inch refractor and Philip with a lovely 17.5-inch dob.  Once dark I ran through alignment on the AVX mount with Mirach as the last calibration star, and I immediately noticed NGC 404, Mirach's ghost, pretty bright oval with a bright central core.  It is an isolated dwarf lenticular galaxy around 10 mly distant, just outside our local group.  Off to a good start.

I ran through a number of open clusters to start, such as M52, NGC 129, and so on.  NGC 7789, Caroline's Rose, was especially beautiful and really does look like a rose, with semi-circular loops of bright and faint stars expanding from the center and folding into each other.  SQML was 20.4 once fully dark.

I then went through mostly galaxies, and I was very impressed with what I could see.  I had the sense I was seeing in the C8+NV what I had seen with my 20-inch from much darker skies.  

NGC 7331: Bright round core, like a ball floating on a frisbee, an effect of the contrast between the very elongated halo and subtle dark lanes on the near-side close to the core.  Flea NGC 7340 noticed immediately, well away from the galaxy, with NGC 7335 seen with slightly more effort, and smaller, fainter NGC 7336 noticed with considerably more effort.  NGC 7336 not noticed at all, nor the supernova, nor the very tiny NGC 7326 or NGC 7325 on the other side of the galaxy than the fleas.  Philip tried with his 17.5-inch, and I could pick out NGC 7340 pretty well, but not any others -- I may not have been dark adapted because of the night vision device.  Richard was able to see the three I mentioned.

Stephen's Quintet: 3 galaxies (NGC 7318, 7319, 7320) seen with certainty as in a triangle, with a sense of the area inside and around the triangle lumpenly brighter from the surrounding skies.  7318 was the brightest, elongated with a bright core, the other two were small soft irregular glows.

NGC 7549, NGC 7550, NGC 7547: Three galaxies forming an isosceles triangle.  7459 was a small non-stellar oval glow, oriented N-S next to a bright star.  7550 was fairly evenly bright, larger round glow.  7547 was small, elongated 3:1 ENE-WSW, with a bright stellar core.  

NGC 40's bright irregularly round shell had brighter edges on either side of the outer shell, like parenthesis.  There was a gap between the bright central star and the shell, and outflows of nebula escaping the poles.  Most curiously, these outburst portions positively shimmered -- not from seeing, but as if by variations in light pulses.  I observed this twice at different times during the night, at different elevations, and the effect was the same.  

NGC 1501: Prominent central star, faint round halo with crisp edges, forms a subtly irregularly round circle, with soft mottling inside the halo.

NGC 382 is in the center of a 14-galaxy group, most aligned in a N-S string.  I drew 5 galaxies in my sketchbook: 382, 380, 379, 385, 384, though a couple of what I took to be stars might have been small galaxies, but I didn't count those.  They all appeared as small elliptical glows of varying size, brightness, and orientation, and it was neat to see them in a string like that.

IC 342: a soft, moderately large round glow, seen best with gain turned down low.  I sense some swirling effect in the mottling, especially near the center bright stellar core, but it is very subtle.  NV does not do well with face-on galaxies.

NGC 891: This was very large, a bit more than the FOV, and very ghostly, seeming to float in the dense field of stars.  Faint, long, with a prominent dark lane down the center.  

NGC 910 group: Just a half degree to the southeast from NGC 891 is NGC 910 and friends, a string of five brighter NGC galaxies, plus a couple more very faint and small NGC and MCGs.  910 was the brightest by far, then leading north like breadcrumbs were 911, 909, 906, and 914 off to one side.  These all appeared as small elliptical glows in various orientations.

NGC 80 group: Another cluster of galaxies of which I saw eight: 80, 83, 90, 93, 79, 85, 86, 96 all as small elliptical glows, except for 90 which was slightly mottled and round.

NGC 772: This is a disrupted spiral and appeared so: a bright core off-center to a diffuse comma-shaped halo with a long bright arm, which I could clearly see, to the north.  Smaller, fainter elliptical NGC 770 was close by to the southwest. 

NGC 200 and others: Another string of galaxies, this time seven in the field of view (193, 204, 199, 194, 200, 198, 182), all pretty bright oval and round glows except for 199 which was smaller and fainter.

AGC 426, Perseus Galaxy Cluster: when centered on NGC 1272, I can see more than 15 galaxies in the field with direct vision, and a few more with averted vision.  Several bright ones, then smaller non-stellar glows appear.  This view more than anything convinces me the night vision device really does triple the effective aperture!

NGC 1023 / 1023A: One of the more dramatic galaxies seen.  Very large, bright, very long arms extending beyond the FOV, and swirly dark nebula around the core.  The eastern tip had a brightening which is elongated at a slight angle than the main galaxy, this is 1023A, its satellite galaxy.  Too bad Jamie wasn't there to have a look!

It was at this point I remembered how night vision does particularly well with flat galaxies, so I pulled out Alvin Huey's Flat Galaxy Observing Guide and observed some I hadn't looked at before:

NGC 100: Lovely long galaxy at least 8:1 NE-SW, with a bright central core and a halo which gently tapers to very fine tips.  Vmag 13.9, size 5.4 x 0.6'.

NGC 522: Small but bright, with a very bright core and long tapering tips, 6:1 NE-SW.  A string of 3 fine stars just north of the galaxy.  Bmag 13.9b, size 2.7 x 0.4'.  Did not notice IC 102.

IC 194: Difficult, very faint, small but very extended streak nearly N-S, slightly brighter round core.  Mag 15.2p, size 1.4 x 0.2'.

IC 176: Very difficult, extremely faint, needed to check the star pattern in the guide to locate it.  Small 4:1 E-W glow with a very faintly brighter core.

NGC 973, with IC 1815 in field: 193 looks like a smaller version of NGC 891, edge-on and bisected by a dark lane, 6:1 NE-SW, Mag 13.6p, size 3.7 x 0.6'.  IC 1815 was a small out-of-round glow with a brighter core.

NGC 1110: Extremely faint, needed to play with the gain setting to detect it: weak glow NNE-SSW, 5:1, very slightly brighter central region and diffuse, very faint tips.  Mag. 15.0 2.8 x 0.5' 

NGC 1145: Fairly easily seen, in an "L" shape asterism of three equal magnitude stars, 6:1 NE-SW, it has a compact bright core, and the halo is mottled -- I have the sense it is slightly inclined towards us showing some spiral structure.  Mag 13.6b 3.2 x 0.5' 

NGC 1163: Very faint, lays off of a triangle asterism.  Brighter bulging core region quickly fading to sharp tips.  Mag 14.7b, size 2.8 x 0.3' 

NGC 1247: Pretty bright, very bright core, mottled inner halo, diffuse tips, 6:1 ENE-WSW.  Mag. 13.5b 3.3 x 0.5'.

IC 2098: Extremely faint, small, 6:1 E-W, with a slightly brighter round core which bulges from the halo.  Mag 14.5, size 2.5 x 0.2' 

NGC 925: face-on barred spiral, appeared as a fairly large, faint mottled glow with a small bright core and a brighter smudge in the halo glow extending E-W from the core.   

NGC 253: Probably the sight of the night: Gigantic galaxy filling more than the field of view, very mottled halo with swirls of dark nebula around the core.

quick observing trip

I decided last minute to head to the "road 6" observing site, on the central coast, on 24 August.  I could fit one quick trip so long as I started driving back at around 4am to get back home and take one of my kids to school after a doctor's appointment.  I planned to have around 3.5 hours of observing, (8:30pm to midnight), 3-4 hours of sleep, and then the 3-hour drive home.  While places like Lake Sonoma and Fremont Peak were shorter drives, their transparency forecasts were poorer.  

This was my first visit to the site, and while the horizons are compromised by trees and hills in multiple directions, it is a large and flat area, peacefully off the main road.  There's a decent view due south through a gap in hills to -43 degrees declination, then on up through Polaris, so at least objects can be observed at culmination.  After setting up I spent some time clearing the area of loaf-sized rocks which were scattered around, to make the area even more drivable.  Once fully dark, my SQML read 21.35 -- not great but around as good as I've had from this area.  Around 11pm I noticed the sky quality had dropped, to 21.2, and I noticed some high puffy clouds surrounding Polaris.  West and south were still clear, so I continued until midnight.  I used my 10-inch f/3.75 Newtonian with a PVS-14 night vision device and an assortment of filters.  Here are some highlights:

M16 Obvious pillars of creation, the two opposite the dark nebula intrusion which points at them -- along with a finger-like pillar to one side.  The nebula was like a shell, the obvious effect of stellar winds blowing gaseous material away.  I traced the wisps of nebula which surround the brightest part to other nearby nebula and was reminded of how connected they all are -- the bright objects like the Eagle, Swan, Lagoon, etc. are simply more visible because stars illuminate them more.  I can't find a good image to show this interconnectedness -- the following, from the MDW Sky Survey, shows the nebula brighter than what I saw, but hopefully conveys what I mean.  

Sh2-12 / NGC 6383 Bright star with a small associated cluster, surrounded by very faint, large, mottled round nebula, larger than the field so I needed to pan around to its irregular edges, nibbled with dark nebula.  Just off the side from it is M6 the butterfly cluster, which when I center in the field, I can see the outer arc of this nebulous sphere.

NGC 6357 Very small intense elongation in the center of a very nebulous field., with many wisps and knots surrounding it, streaked with dark nebula, speckled with spheres, and wisps trailing from it in all directions.

NGC 6302 Bug Nebula.  I can see it unfiltered, but it completely disappears with the 685 longpass filter, best view TriBand filter.  Though at small scale, I can see the two ansae, one longer than the other.

M57: Bright and round.  Due to small scale, I didn't look for detail.  But in a 2-degree field, the goal was not to see particulars of the nebula, it was to see it floating in the myriad of stars the night vision device reveals.

I woke at 3am after a too-short nap in my car and got out to stretch.  Looking up, I could see M31 in between puffs of cloud.  And then I heard the soft leathery flaps of bat wings and looked up to see a very large bat 10 feet above me, quietly making its rounds.  Starting the drive home, listened to Heinrich Ignaz Franz Biber's "The Rosary Sonatas," also called "The Mystery Sonatas."  I bought the CDs from Half Price Books out of curiosity a few weeks ago, not knowing anything about the music, and left them in my car.  I was shocked by their beauty and the virtuosity of the playing.  Biber wrote in the late 1600s, and in parts the sonatas sounded like the honed results of his improvisations on the violin.  He was the Jimi Hendrix of his era, finding new sounds and possibilities with his instrument. Travelling through the tunnel of light formed by my headlights, I saw a frog hopping across the road, a few mice, a young bobcat zigzag in front of me.

I don't know if it was my exhaustion, the exhilaration of seeing things in the sky very few humans even know about, or the transcendence of the music, but I was in a mystical state of mind.  Starting on the main road, I felt my tunnel of light was leading me through a sort of hell, at least an astronomer's hell, complete with vapors and fiery lights.  Few of us travel to our observing sites at night, so it was disturbing to see why the sky quality is not as good as the light pollution map would promise, and why we resort to ever larger aperture telescopes or technology (astrophotography, night vision) to enjoy this hobby.  The nearby military base casts its own light dome.  Individual farms blaze with security lights on sheds and barns.  The haze of fog in the Salinas Valley diffuses the light into the sky, rather than blanketing it like a marine layer.  I noticed a pillar of light, like something from the Bible, forming an awful vertical rainbow miles ahead of me before reaching the source: nighttime pickers at their hard labor, following behind the brightly lit sorting machine and tractor.  Multiple buildings along 101 have bright unshielded lights pointed up.  One large multistory building under construction had around 10 floors framed but lacked outer walls.  The entire inside was brightly lit up -- I presume for nighttime construction crews -- it was bright enough to light the interior of my car though it was a quarter mile away, and it formed a sickly glow in the sky above.  One winery had its tank and pump system completely lit up.  I think north of San Francisco is not being developed so much, so places like Lake Sonoma is getting to be darker than sites south -- unfortunately north typically have worse transparency.  In any case, it does not bode well.

Fortunately, the 2 CDs worth of Biber's music carried me home safely.
