Re: Telescope used by Goodacre,Elger,Neison and Wilkins & Moore

Interesting article Mike. It's nice to know that it went to a person who appreciated the history of the telescope. The old 12 inch Calver that I borrowed from the BAA many years ago went to a Victorian-style observatory (The Wrottesly-Phillips Observatory) after I passed it on. It had originally bel...

Re: Nova in Cassiopeia

Jeff, brilliant observation and images. From a careful look at your image and nearby comparison stars the nova's magnitude does indeed look like 9.0. (the star right next to the nova is visual magnitude 9.12). I am making an assumption here that the camera is rendering 9th mag star images that are c...

Re: Nova in Cassiopeia

2021 November 23, 1805 UT, 90mm refractor x41, the nova has faded significantly. I estimate it at magnitude 9.2. Bob
Anyone else making estimates?

Re: The SUN - 21st November

Hello Cliff, good to see an image lately. Would love to see one for today's Sun (22/11/21) because I definitely saw the northerly dark spot as double today. Yesterday's seeing wasn't too good so I didn't see the southerly spot as double then but I did see faint mottling around it on the photosphere ...

Re: The Sun Today

Brian I was intrigued by your observation so I looked at the SOHO images tonight and I think the filament you describe (and other absorbtion features) are in the region of the southerly spot where I noticed faint mottling in the projected white light image. It's good to see visual H-alpha reports he...

Re: Large dobsonians

Mike, I agree with absolutely everything you say about outdoor covers because I had exactly the same issues with a 12 inch cast iron and steel Calver some years ago; additionally when it was windy the blooming cover came loose no matter how well roped down it was. The motorcycle type cover that I'm ...

Re: Large dobsonians

Skybrowser, some covers have a condensation/corrosion inhibitor system, like the Louis VCI Folding Garage in various sizes. I haven't used one yet.

Re: Large dobsonians

Skybrowser, good luck with your project and keep us updated. I aim to replace my leaky old garage next summer and keep a telescope in the new one inside a dehumidified type of plastic shroud that you overwinter motorcycles in. So I'm very interested in what you are doing. Bob
