Hi Rog, Once again wonderful pinpoint stars at a relatively long focal length. I'm still out of commission for imaging but the replacement computer system's coming along. Would like to implement ASCOM communications but to expedite matters it looks like I'll be using the previous slower setup and at...

Did you catch the Starlink Satellite Array pass this evening? 22 satellites ranging in brightness from 0 magnitude to 2 mag marching from W to E from approximately 19:41 – 19:45 hrs. While a pair of satellites isn’t uncommon I’d never seen anything like this Spacing was anywhere from 3° to 20° separ...

Wonder if it were possible to do a spectrographic analysis of that questionable area to determine whether it's biased toward Ha or Hb? If Hb the autocolor version would probably be more accurate.

This is the observing list from last week's 18:30 - 20:30 hrs class. And we were successful with all objects. There are 2 more classes to go and other than adding Jupiter I'm at a loss as to what else beginners with an untrained eye can visually appreciate. Suggestions would be greatly appreciated. ...

Rog, your longer than normal cluster exposure brings out about a million faint/tiny background stars. Never thought about long exposure for star clusters.

Such detail on such a relatively tiny DSO. If I tried that my stars would show at about 1/4" diameter.

Gosh, for a simple 4 star group you make it so very interesting Roger. This is one of the things that I emphasize in my Backyard Astronomy class. If you don't understand what you're looking at it's pretty meaningless.

Tuesday, 12 Sep 2023 Right in the middle of a bunch of storms tonight’s sky is transparent and still. More stuff coming in but this is the perfect opportunity to image a cluster that has captured my imagination – Caroline’s Rose. Setup unchanged so can use flats from Sep 1st work. 74° F. With the ai...

Blue Moon / Supermoon tonight at around 21:30 hrs. Hurricane Idalia is passing to the south and there’s enough cloud at the fringes to inhibit imaging. Up again at 01:00 and the sky’s relatively clear. So the captures were actually 4 hours past "full". Some wispy cloud but the stars are vi...

Friday, 1 Sep 2023 What a beautiful clear still night for observing. There’s a full moon rising but the first hour of work is very dark and the rest of the time the dome blocks the scope from direct moonlight. A multi-star focus routine results in a FWHM of just 3.8 and that’s as good as it gets for...
