The Moon and Jupiter 10 Dec 2024

Image
  Sky was looking clear so I set up about 19:30 MST. Plan was to just look at the Moon and then Jupiter. I used Solar System Alignment with Jupiter for the alignment target. I messed up and put the date in as Dec 12 instead of Dec 10! I didn't realize what I had done until later. GoTo was obviously off  because of that, but tracking was good and I was able to scan over to the target, Moon was at 77%, very bright, and was the first target for observation. Just after I got aligned and moved to the Moon a layer of cloud started moving in from the northwest. it eventually mostly obscured Jupiter. It kept moving SE and didn't affect the Moon. I initially had the 32mm eyepiece in just to scan and look for interesting features that might catch my eye. I didn't have the Moon filter in to start, but it was so bright it left an after image in my eye when I looked away. I put the filter in to make it easier to look at. I started looking along the terminator and the rim of Montes Jura ...

 Tonight was a little bit of an exercise in frustration. Starting about 20:0 0MDT I tried setting up the tripod and leveling it before attaching the mount and then the telescope. In the process, I bumped the tripod and knocked it out of level. Grrrrr! I eventually got everything set, and was able to successfully bring targets into the field of view. I am really looking forward to getting a permanent pier put together!  Skyglow was pretty bright despite the Moon not being up. Seeing was fair. Transparency wasn't great, with a NELM (Naked Eye Limiting Magnitude) of about 4.  The first target was M2 , a globular cluster in Aquarius. It is about 55,000 light years away and contains about 150,000 stars. I was only able to make out a couple of individual stars on the periphery by using averted vision.     Second set of targets wee from the AAVSO class. Z Andromeda and AC Hercules. Hercules was just past zenith. That is a difficult angle for me to see with the red dot ...

Tonight was clear enough that I set up my telescope. Set up at 21:00 MDT, and aligned using Altair and Polaris. GoTo was still consistently off to the left in the east part of the sky, but was able to use the RDF to get on target. I am obviously missing something in set up. The most obvious suspects are date and time entry.  Transparency isn't real great and the sky was pretty bright, so I decided to just try some easy observing to relax.  I hadn't done any planet observing in a while, and Saturn was up. I started with the 25mm eyepiece and progressed to the 8mm. The rings are almost edge on, just a little tilt to them. Seeing wasn't real steady, but there were moments when it steadied. I could make out a very thin dark space between the rings and the planet on either side of the planetary disk, And could easily make out the rings in front of the planet. The north atmospheric band was occasionally faintly visible. There was no real discernible color. The planet appeared whi...
