    Aside from astronomy, the rubrics above my daily log page would include History, Philosophy, Languages, and Numismatics. I also devote a lot of time, thought and energy to writing. I typically publish ten or 12 articles a year.

  1. Your Schmidt-Cassegrain may need collimation. I do agree that the views through smaller apertures can be surprising and delightfult.
  2. It is a bit of a problem reading in the dark. I will plan out an observing session and I can usually follow my notes. But the other night, I just wanted to squeeze in a reminder and I wrote it in red ink. Oh... So, I went over it in black. But it occurred to me that if I used my cellphone for a note keeper, I could record those little reminders. It's a thought. Thanks.
  3. Capricorn is missing. The index has one entry for alpha Capricorni (Algiedi). The citation takes you the close of a discussion about epsilon Lyrae in which the stars are compared along with omega Scorpii and omicron Cygni as available naked eye to the sharp or fortunate observer. Nothing else in Capricorn is in the book. I photocopied a page out of Sue French's Celestial Sampler and put it into the Anthology where the data and narrative would go. We are going to have clear skies here (finally!) but the forecasts are favorable only for early morning hours, midnight to sunrise. S
  4. I keep a notebook. I am on my second. This one has both lined and graph pages. I sketch, often to scale, or just record in narrative.
  5. Arrived today. I was using a library copy. After checking it out and renewing it four times, I bought the book. Now, I am going to put all my post-its in my copy and return the library book. I have a long review on my blog. BTW: Whevever I can, I buy from the publisher so that the author gets the royalties.
  6. I found the summary to be sophomoric nonsense. I downloaded the original paper and quit trying to read it. Some years ago, I read a doctoral dissertation on the nature of angels. Like, if all angels are equal, then when one angel learns something, do all angels instantly know it, also. Same here.
  7. Fascinating! Thanks for providing this and the link to the story of the Thorrowgood telescope. On a related note, the Yerkes Observatory of the University of Chicago was purchased by a foundation which is refurbishing the grounds with plans to be open to the public. https://www.wpr.org/todays-big-day-wisconsins-yerkes-observatory-has-new-ownership
  8. Bresser owns Explore Scientific. I do not know all of their ins and outs on finance and management, but the two are linked, and I believe that Bresser is the senior partner. I do a lot of shopping with Explore Scientific, though I do patronize others, of course. Their owner Scott Roberts spoke (via Zoom) to a meeting of our local club. And on that score: One of very many reasons to be in a club. You did the right thing by joining. Our local club lends instruments to members and I have used both an 8-inch and a 10-inch SCT. They were nice for viewing, but a bear to lug around. That's w
  9. Well, that's the way it's done. We look forward to your reports. In addition to this board, what kind of reading do you do? In your gear acquisition phase, did you buy any books?
  10. That's a bit of a jump. I believe that you will find that as nice as the big glass is, your EQ-127 will still see some action, especially as you want to do astrophotography. You are cruising right along... Congratulations. Keep us posted.
  11. Right now, I live at 30N, but I grew up at 40N (Cleveland, Ohio), -- and in a nod to @Adam1234, a mile from the steel mills -- and for a few years, we lived at 45N (Traverse City, Michigan). Right now, I am in the city limits (two-county metro of 1.8 millions) and a mile from a major shopping mall. For me, a good night is Bortle 7 almost 6-ish. So, just to say, you make the best you can of what you have. It is like with telescopes in general. I have modest refractors, not dobsonian light buckets. But there's always a better instrument. You could have Keck and still feel disadvantaged be
  12. It took me a couple of days just to figure out the user interface. I attended several re-caps of talks, but missed the talks themselves. (They are recorded.) However, I got caught up and brought up to speed. I sat in on the Vera Rubin Early Career Prize Lecture by Jackie Flaherty of the American Museum of Natural History. Unlike most other museums the AMNH supports research scientists. Dr. Flaherty spoke about objects close to us such as brown dwarfs and Jupiters. I was surprised at how much there is that is only now being detected. Except for famous neighbors such as Barnard
  13. I bought an Astro-Tech 115 APO. I was happy that it came with a case. It did not come with other stuff. Explore Scientific 2-inch 99% diagonal. This is for my ES-102. Stellarvue right angle with focusser. Meade Not-Meade unbranded 14 mm waterproof 82-degree ocular from Astronomics.
  14. Did you know that Galileo used shadows to measure the height of a mountain on the Moon? He was far off in his results, but the process was correct.
  15. Not that much mathematics was required all in all. As long as you understand the concept, it is enough. You do not need to grind through differential equations or integrations to provide a numerical answer. I am now working through this book. If I had not had the EPFL course, this would be even more opaque.
