Re: Jupiter and Saturn closing in ..

Swept up this evening in the 16x42 finder at 1615 UT. In the 90mm refractor at x82, low across the road and to the right of bare winter trees in a twilit sky. Jupiter is very bright with a couple of satellites visible. Saturn is dim and chromatic with the ring coming in and out of focus. Yay, wife a...

Re: Solar observation via projection

These 60s Japanese refractors usually have decent objectives, though the eyepieces are tiny and basic by today's standards aren't they? At any rate I am not surprised an old zoom ocular doesn't give a sharp projected image. But before you set it aside, consider that the Sun is low at this time of ye...

Carry the torch, Skybrowser, a lot of us are getting too old for that kind of meteorthon.

Re: Arecibo Telescope to close.

Apparently the tin pan can’t do radar Brian, which was a big thing with Arecibo, for imaging NEAs etc. Arecibo was more versatile. Bob

Re: Solar observation via projection

Hello Skybrowser, I project the Sun with a 90mm refractor stopped down to 60mm at F15. Please excuse my lack of certainty (I’m not into the technicalities of sunspot identification - I just record what I see) but I did project the Sun yesterday and recorded a group of 4 spots amid faculae near the f...

Re: Old Mars from 2016

Interesting image! It’s similar to the view, resolution-wise that l have had in my 90mm refractor this opposition. Thanks for posting this. Bob

Re: Geminids 2020

New Farnley, south-west Leeds, 2020 Dec 13, 2334 to 2352 UT, looking east and south, 3 Geminids seen: one south mag 0.0, one ssw mag minus 1.0, one east through Cancer maybe (hard to position because no naked eye stars in the area due to artificial light) minus 5, white fireball, one second ending i...

Re: Betelgeuse fades again

Hello, interestingly there is quite some uncertainty about our old friend's distance, size and luminosity these days: however, the variability is something we can all see with the naked eye. I made a more reliable estimate this evening at 2120 UT. Compared with Pollux, which was at the same altitude...

Re: Betelgeuse fades again

Hello, my estimate for Betelgeuse at 00.30 UT on 13 Dec 2020 is Procyon minus 1 or 2 steps: an odd impression of it being somewhere between the two. I know that’s a daft statement but with Procyon at mag 0.34 I would put Alpha Ori at 0.5. Other, better estimates would be welcome!

Re: Book Review:Hirshfeld's "Astronomy Activity and Laboratory Manual"

Michael, this author also wrote an interesting book on the history of astronomy in the search for stellar distances: it’s called “Parallax”. I enjoyed it. Bob
