    I just read an article in the SPACE WEATHER website about a Surface Mass Ejection (SME). Astronomers believe that in 2019 a colossal piece of the star surface blew off. It's in the Friday, August 12, 2022 page of Space Weather.com

    You can also do a search on 'Betelgeuse SME' and find articles about it. There is also a link to a UNIVERSE TODAY article in the Astronomy and Space News of this website.

    Very interesting the article on Betelgeuse from space weather. I will browse that website from now on, thanks for sharing it here.

    They say that the star is now back to it's original brightness, returned to normal, I was not aware of that.

    One reason I frequent the Space Weather website is to check up on solar activity. I have a small, inexpensive white light film filter that fits my 55-250mm DSLR lens. When sunspots are active, and weather cooperates, I'll snap a few frames. I can either stack the frames or process a single one. This year the African dust has been especially bad. The dust keeps hurricanes at bay, but negatively impacts just about everything else, day or night. BTW, I'll take the dust vs a hurricane.

    @Ed D

    Oki oki fast setup to snap pictures of the sun. That filter is is something you screw on the lens of the camera or it's a DIY that you fit over a standard camera lens?

    Ouff ok so in Florida, you get probably, the salt air from the ocean PLUS the African dust. Looks like a challenging place to do astronomy.

    Here in Québec usually we have smog from the fires in the west each summer, it cuts the transparency.

    My filter is a Baader film filter that I picked up from Agena Astro: https://agenaastro.com/baader-astro-solar-spotter-filter-assf-50.html

    I bought it originally to use in a small spotting scope to observe the August 2017 solar eclipse. Didn't use it afterward because the sun was in a dormant cycle. It happens to fit my DSLR lens. Now that the sunspots are active again I have used it a few times for imaging.

    I'm inland several miles, so ocean salt air doesn't really affect me. The biggest challenge for me is that I live in a severe Bortle 9 zone.

    @Ed D Ahh oki it,s a astrosolar but the whole assembly is made by them also. I had never seen these filters from Baader, they look well built and really affordable.

    I built my white light filter with a astro solar filter also, 8" for my 8" Newtonian. It's a large solar filter, it's very good with my teleescope!

    Bortle +-7 here.. it's difficult for DSOs.

    I'm really surprised and amazed that I can actually image many of the brighter DSOs from my backyard. The biggest challenge I have is finding them in a very bright night sky.

    Me too I can visually look at dsos from what looks like deadly pollution at home, it's still impressive. It happens often that I am too tired to drive to a dark spot, having observation at home and it's incredible nonetheless less to look at the astronomical wonders.

    We are alone on the forum, it's sad...
