Astronomy

I know we did Fridays last time. The weather was bad, so I kinda forgot about it. The transparency tonight is looking suboptimal, and, given my options, I might just settle for hitting some binary stars. My best view is of the eastern sky, and most everything there right now is faint fuzzies, so I don't have especially high hopes.

Hi, I thought I'd share this here since it isn't being covered by any news sources. It's mostly my own research and calculations, so it could be completely wrong, but I'm fairly confident it's correct.

I'm planning to go to a rural spot that has a Bortle class 3 night sky around Southern California. Can anyone recommend a beginner friendly telescope with decent magnification for around $200? I'm not interested in using an accompanying smart phone app to go with it either. I'd like to see nebulae and galaxies the most. Thank you.

I've got clear skies where I'm at, and I'm ready to try and cross some things off my observation list.

Does anyone have any experience home brewing a radio telescope? I'd really like to make one myself, both because it seems fun and challenging, and because it would probably be cheaper than buying one of there are any consumer grade radio scopes. I'm aware of some tutorials online, and one concern that I have is that many of them are intended to output data to software. I'd like to convert the signal into something audible, so that people can actually hear the emissions. The three targets I have in mind are: the sun, Jupiter (like the JOVE project), and hydrogen emission frequencies from nebulae. Ultimately, my goal is public outreach and education rather than amateur research.

Hey everyone! I'm putting on stargazing classes in my city with the help of the city parks dept. It involves lugging out 12" dob (we mostly hang out ~120x mag, but I have plans to really juice the magnification if we get small classes and good seeing), some binoculars, and a green laser pointer. I just did the first one last night, and I found it to be a hugely rewarding experience. Unfortunately, the class was a bit on the smaller side and not asking too many questions (I think because it was cold AF for California), and I found the energy kind of flagging halfway through. My plan has been to teach the basics of star finding, telescope use, etc. and follow the Astronomical League's Urban Stargazing program (I want to help folks get certified if they're interested). I was wondering if anyone else has done any kind of astronomy public outreach and if they had any advice to help keep the engagement up when folks are taking turns peeking through the scope. In case you might be wondering, it's not a GOTO or PUSH TO scope, I personally find that there's a bit of magic in manually slewing the scope, but it does unfortunately mean that I spend extra time bringing the scope back on target between students using it.
