Used the 20-inch, just to exercise it since it's been a while since I observed with it. The seeing was average to poor, so I masked to 7-inches throughout.  A short session, just a couple of hours before needing to turn in.

A pleasant night out with the 6-inch.  I started after 9pm and finished around 11:30pm, with 60 objects observed.  DSC was spot on, and I could move quickly, and there were a lot of unobserved objects on my list.  Waxing moon out, and poor transparency, a milky haze throughout the sky.  But still good enough for some fairly difficult observations.

A clear night, finally, with predicted above average transparency and above-average seeing.  I opened the 20-inch full of hope to chase after movement pairs.  I did so, trying for Rigel, Sigma Orionis, and Procyon during the early evening.  I have elongation of Rigel, no success on Sigma or Procyon.  It eludes me by I can't see Procyon.  I did get a couple very tight movement pairs early in the night, but both transparency and seeing gradually became worse, I had pointing accuracy problems, and even stiction.  I sprayed the alt and az with lubricant, but it was so free now the scope nearly crashed as the OTA tipped forward, making the mirror pop from its cell with a worrying clang.  No damage done, luckily.  I felt good to be outside, but I would have wished for more success observing.  I alternated between 20-inch with apodising screen and the 7-inch off-axis mask.

I will confirm: refractors give much better star images and contrast than even the best reflectors (and my mirror is near perfect).  I could tell the difference all night long.

A clear night, with some haze but only average seeing.  I used the 20-inch, but masked down to 7-inches for most of the night.  I hadn't used the scope for quite some time.

Despite the indifferent seeing, I tried Procyon when it transited -- and I think I saw SHB 1 AB!  I was at 7-inches, 285x with a neodymium filter, and using the central peephole in the eyepiece cap.  Nothing with the star at the center of the very narrow field, but when I placed it with A along the southern edge of the peephole, much of the diffraction was absorbed and there was a steady star, about the right separation and about the right magnitude, about exactly north PA: all of which confirms B.  To check for aberrations I placed A along the north and east and south edge of the peephole, and did not see any such brightening or star.  I moved A back to the west edge, and repeated the observation.  Now, given my history with this star, I would like to repeat the observation on another night.  And, it would be nice to see the star cleanly, without employing tricks like peepholes or occulting bars.  But, I'm excited by this and feel better about this observation than those in the past.

16 january 2025

A very productive night with the 6-inch.  Seeing was quite good, nearly perfect at higher elevations.  A bit of typical marine haze.  Cold, in the upper 30s, and light dew.  I observed from around 7:00 and caught the beginnings of an Io shadow transit on Jupiter, and Venus and Saturn close to each other (through branches of a neighbor's tree), and Mars, with a polar ice cap and dark features visible.  I ended the night around 11pm with a bino-viewed look at the moon.  All around a great night.
