challenger night

Given I am unable to go to CalStar this year (and just as well since the weather looks poor), I took an open window to go to Fremont Peak last night to observe with the Challenger. I arrived at 6:00pm and opened right away, since it was close to 100 degrees in the observatory, and in the lower 80s outside. I ate and tried to take a nap. There was no one else there on a weekday night, and maybe only a couple of campers. It was nice to have the silence; no highway noise, just the crickets and an occasional hooting owl. Seeing was fairly good at 7/10 (and Jupiter and Saturn looked fantastic in the 5" refractor finder during twilight), but transparency was not very good, as evidenced by my difficulty observing even bright galaxies and the thin cloud cover in the morning. The focusers were all out of collimation. It was warm, just needing a tee-shirt most of the night. SQML didn't get higher than 20.8, and the Salinas sky glow was very pronounced. The site is very compromised, really only good when there is a marine layer, but there was none last night. I didn't try to use The Sky with the Challenger, so I was left only to star hop. I forgot to bring my RACI diagonal so this was a frustrating experience. I really need to learn how to use it since star hopping on this scope is a chore and I'll end up hating it.

Something special was a bright meteor travelling N-S through Cetus, which I saw while taking a break (at around 1am?) while sitting on the south facing bench on the pads.  Not only was it bright, and left behind a smoky trail which lingered a seconds, but I also heard the meteor.  I was out of ear shot of the Challenger's drive, which makes a continual grinding noise.  I heard a "ssst-pop" sound, coming from over my head and a little forward.  I heard it just as the tail was fading.  I found out at home later that these are called electrophonic meteors, and others report them too.  It was really cool to hear it.

Gamma Hercules: Someone posted on Cloudy Nights about DRS 58, a companion to Gamma Hercules. It was listed as 8th magnitude and 8" separation, though this is K band so the visual magnitude is something like 13. I tried it a couple times at home last week with my 20", employing an 9mm orthoscopic eyepiece with an occulting bar, but without success. This was my first target and while I noted several stars fairly close to the bright and swimming A (having set it below the occulting bar), none of them match the stated PA of DRS 58. So this will need to wait for another season to try, since Gamma is getting low.

5 Equ: 30" 118x: I don't find this in Stelle Doppie so will need to check my reference later. It's a double star in Equuleus and was immediately seen as a faint blue star, fairly wide from it's A.  [This is a terrible notation.  KNT 5 AB is 0.6" and 4 delta mag, and doable at high magnification.  BU 71 AC is nearly 8 delta mag and 60".  STFA 54 AD is only 1.3 delta mag but 335".  It's likely I saw the STFA, but I really didn't keep good notes.  In my defense, I was there for deep sky, not doubles]

I found M5 as a reference then moved to some things around it:

NGC 7068: 30" 457x: Near a bright star to the north, and a faint star just below it to the east. The galaxy is a dim streak, 4:1 N-S, but with a brighter bulging core and bright but non-stellar nucleus.

NGC 7094: 30" 166x: Shell is not seen without OIII filter. The central star is constantly seen. Shell has a fat tire shape, with a small dark hole around the central star. The outer shell is unevenly round, and between the dark hole and the edges there is some mottling or change in brightness & texture. The edges are generally soft, but there is a brightening with two knots on the NW and W rim. This did not take magnification well, it seemed to spread the shell out too much.

QSO 2237+0305 Einstein's Cross 30" 457x: After a long and careful star hop I found the correct region, using a backwards "L" asterism as my final finding pointer. I could see the lensing galaxy very consistently as a 3:1 glow with a brighter core. There was a faint star just to the north of the galaxy which I used to fine-focus and to monitor the seeing. When the seeing stills this star sharpened to a point and I knew that was the best moment. I spent about 20 minutes looking, and there were about ten instances in that time where a white point hardened in the haze a little offset to the south of the what I think was the center of the galaxy. This might have been the A component. A few times I felt there was a second such point, though much, much fainter -- which could have been C. But these views were so fleeting I wonder if it was simply the lensing galaxy's bright nucleus revealing itself. So the quest will continue.

BTW the corner star of the "L" appears to be a double, 7" separation, about 3 delta magnitude. I also felt the star at the tip of the small line of the "L" was also a double, very close, about 1" and a large delta mag. I don't see a second star marked at that position on Aladin.

NGC 7463, 7464, 7465: 30" 118x & 457x: Galaxy mash up. Three galaxies 3' to the NE of a bright 8th magnitude star. N7463 is largest, elongated 4:1 E-W, with a bright and mottled core, showing what must be dark lanes. It has a large faint halo of sweeping arms -- the arm to the west is brighter and emerges from the NW corner of the elongated core and sweeps West before turning south and seeming to envelope NGC 7464. N7464 is small, faint, brighter core with thin diffuse halo, and actually wedge shaped, like an arrowhead pointed WSW. A bit further to the east is NGC 7465, which is small, bright, and round with tapered tips pointed N-S; looks almost globular cluster like (in the DSS image there is a cluster of very faint stars scattered to the south of N7464. Is this an uncatalogued open cluster?

NGC 7468: Bright bean shape glow, N-S, almost no halo. Barest hint of dust lane? [I was just picking up on the odd misshape to the core, which is kind of notched].

NGC 7503, 7499, 7501: 30" 166x: Trio of faint ellipticals in an arc E-W, like an eyebrow. 7501 & are slightly closer together. There's a scattering of stars beneath the "brow" making the whole scene oddly circular.

NGC 7529: 30" 166x: Very diffuse, barely there, small round glow. Tough to make out. Did not see IC 5291.

NGC 14 = Arp 235: 30" 166x: Elongated 3:2 NE-SW, brighter mottled core increasing in brightness to an oval shaped nucleus. The faint halo, which at 457x spreads more brightly to the SW like a comet tail and envelop a faint star [DSS shows this glow and faint star].

NGC 240: Round mottled glow 1' to the NE of a ~10th magnitude star, diffuse edges, stellar nucleus. There seems to be a star or knot in the NE part of the outer halo.

NGC 584 & 586: 30" 166x: N 586, Bright compact nucleus and core, elongated 3:1 N-S, mist of a halo around it trying to organize but can't quite. N 584 a bit formless and diffuse, generally brighter in the middle.

NGC 596 30" 166x: Bright nucleus and core, round halo, mottling between halo and core. Must be spiral. Near bright star.

NGC 467 = Arp 227, 30" 166x: Bright with a compact core and round small halo, 3.6' to the west of a 7.5 magnitude star. I believe it is an Arp because of the small galaxy (LEDA 1249151) 1.6' to the west which appears to be enveloped into its halo; did not see this galaxy.

NGC 470 & 474 30" 166x: On the opposite of the star from NGC 467. NGC 474 has a bright mottled core elongated 3:1 N-S. DSS image shows a huge round surrounding halo, not seen. NGC 470 is the largest, but faintest, with a stellar nucleus and obvious mottling in the halo -- definitely spiral but very disorganized.

NGC 520 = Arp 157 "Flying Ghost": 30" 166x: Very interesting object. A faint star on NE end of a cometary shaped galaxy, bright elongated core lopsided on the same side as the star, with a mottled, ragged halo which trails off to the SE. [This is an interacting pair; the disks have merged but the nuclei have not yet.]

AGC 194: So many galaxies, popping into view in the general fog of the area and with averted vision. A bit much to describe but my field sketch of the area notes 16 galaxies within a half degree field of view.

M74 30" 166x: Gently inclined spiral, brighter on East end, brighter core, mottling suggesting spiral within the whole round halo, diffuse edges. .

M77 30" 118x, 166x, 457x. The core appears like a spiral within the larger spiral, like a cat's eye shape. The core itself has dark lanes which separate it from the larger halo. Definite spiral structure in the halo. Intensely bright nucleus. The huge halo sweeps like a shell or wave on both north and south sides, though is it brighter on the northside. There's a bright star in the spiral arm gap on the south side. Very great object, takes magnification well.

23 september 2019

Last night was pretty good, in spite of mediocre seeing (around 6/7) and 2-3/5 transparency. Seems I haven't had a clean clear night in ages. Nonetheless I captured a few difficult pairs. I replaced my hand controller cable, which had three connections to it (going through a stalk and then extending out to the HC itself) with a single cable running from the Servo CAT to the HC. The control was much improved; what I thought was backlash delay from when I pressed a button to when the scope moved, I think now was really just a poor connection between the HC and the Servo CAT. It makes me consider if I should get rid of the stalk connections altogether, since this is meant to be a permanent set-up, I don't need the stalk interface...

c/2018 w2 Africano

Saturday night Clara and I helped do outreach at Fremont Peak.  We brought the 10" Dobstuff and had an enjoyable night.  Clara got more used to moving the telescope and was able to find Jupiter & Saturn on her own.  Once it was fully dark I showed off the eastern Veil Nebula for the public.  Before we packed up we had a go for the comet C/2018 W2 Africano, which I was able to find pretty easily.  The finder chart got me in the general area and some spiral searching brought me to a faint but easily noticeable glow, about half a degree across, with a brighter central region and faint & diffuse coma.  I did not notice a psudo-nucleus but I did notice the beginnings of a tail.

I like the 10" very well but I hate the Destiny secondary mirror holder, it cannot hold collimation.  I am replacing it with an Astrosystems which is on the way.  I want to replace the focuser too, since it doesn't handle heavy eyepieces.  It could be a great little scope with some minor improvements.

CalStar starts on Wednesday, but the weather does not look promising.  In any case I can't get out this weekend. 

20 september 2019

Seeing was rather poor last night, as was transparency, so I kept the 8" mask on most of the time. A pleasant night and I was happy to be out. I saw a large possum walk along the top of the back fence, not minding me at all. My hand controller went on the fritz; I think I'll replace with a single cable instead of mating to couplers. So I just spent some time at the end looking at some bright DSOs, NGC 6940, a wonderful large open cluster in Cygnus, and the amazing M15.

barely clear

Last night was a bit frustrating. Seeing was not very good, but that was as predicted, so I just used the 8" mask for decent images. The transparency was poor, very moist, just below cloud forming level. I did get a few observations in. The frustrating bit was the Servo/Argo cut out mid slew again, causing it to revert back to FIX ALT REF -- meaning I would need to redo the star alignment. It happened just after 10pm and I didn't have the motivation to try to fix it to continue. I don't know if it's an encoder problem, motor problem, software problem, etc. -- I'm too far away from the Argo to see any messages since they only blink for a couple of seconds... I'll check out the mechanicals tonight.

My observing window (the area of sky best for viewing, higher up and west of meridian) is moving through Cygnus now, so there are plenty or rich star fields to explore. I stepped inside midway through the session to help with some chores, and found upon my return my dark adaptation was greatly reduced, I had trouble seeing the pair I had been looking at just before. So those who say dark adaptation or averted vision doesn't matter with double work really don't know the truth!

The sky was clear(ish) this morning; it would have been a good opportunity to observe the moon. There is still some darkness left in the mornings at 6am when I get up, so I should make the effort to get out and observe a little in the mornings.

pseduo nebula

Very thin clouds blew in from the ocean tonight, and were illuminated by the just past full moon.  So I simply lay on my hammock with a pair of binoculars and had a look around.  It was actually good practice for seeing nebulae, since they too are mostly things without light reflecting the light of things which do.

I counted five sweeping arcs of cloud, each with a brighter leading edge curving in the same direction, to the same distant, hidden point.  The density of cloud thinned in some areas, and for a few minutes was able to see, for example, hints of the star crowds where the North American Nebula was supposed to be, around Gamma Cygni, and down the Swan's neck.  I found the Coathanger.  And Lyra just overfilling the field of view.

But the main show was a band of vapor trail, perhaps a half hour old, still thick but spreading, and drifting toward the moon.  With the moon out of the field I studied the billows and eddies of the cloud, and pretended it was a kind of Veil Nebula -- in fact it looked very like it as it glided over the moon, a substitute for 52 Cygni and the Witch's Broom.  Some kaleidoscopic colors reflected off the ice crystals.  As it moved further away it grew flatter and less detailed, hidden now by the angle of light and not its lack of existence.

And so the night will age, with gentle swells of cloud playing in the light of the moon.

11 september 2019

I had high hopes for last night, but they were frustrated by seeing and transparency and a couple of technical issues. I screwed on a couple of small weights to the back of the scope in order to better balance it (it drifts down after about 40 degrees). During the beginning of the session, when I was slewing to objects and the altitude was starting up at a high rate, the motor just cut-out. The Argo asked for FIX ALT REF -- meaning I had to redo my star alignment. This happened twice. I don't think it was due to the weights, but probably the tension of the alt cable or perhaps an encoder error.

Seeing was forecasted to be good, and it started out ok, but it totally broke down after 10pm. Transparency grew worse too. This morning I hiked up Mission Peak and saw the reason why: A pall of wildfire smoke is hanging over the north bay, the edge along route 84 and going north, and from the ocean to the east beyond Mount Diablo and into the San Joaquin valley. Ugh. It's very hot these next couple of days, so I don't think there will be any wind to push it out of the Bay Area -- smoke usually pools in the Bay Area until a weather system comes through to push it out.

So, I ended around 10:30pm after starting at 9:00pm. Short session. I closed by binoviewing the moon, but the view was soft and discouraging. Interestingly I seem to hit a vein of POU doubles; there must have been a study done in this area of the sky (eastern Hercules)--though most of them have been shown to not be physical pairs.

3 september 2019

Started observing a little after 9pm. Transparency still on the poor side; I could smell the moisture, it started dewing early, and the waxing crescent moon had a glow around it. This would limit how faint I could go. Seeing was ok to start, 6-7/10, but by shortly after 10pm it turned really bad, and even the 8" mask couldn't keep up. So I had to shut down a little earlier than I hoped. Still, there were a couple of special observations last night. There were a number of "BRT" designations in the area of Hercules I explored; I'm guessing the results of a particular and focused study.

Had another late start last night, around 10pm, but I observed until 12:30 and racked up more observations than I thought I would. I intended to go to a dark sky site but family needs kept me home. Seeing was middling, 6/10 at best, and transparency was well off, 2-3/5. I could smell the moisture in the air. So I found myself limited to the magnitude and type of splits I could get. I did get a couple new designations, so not all lost:

STF 2419: AB: 8" 333x: Seeing surprisingly and frustratingly bad. Bloated stars. This pair at 333x about half delta mag, well split 3" white.
