Nice, Valery. Mini-activity offers a lot more areas to capture if you have the resolution.

Nice capture, Dave! Good details in this prominence.

BTW Does it mean you do use the 35mm etalon for DS (for LS80T) mounted in 160mm refractor?

Valery

Thanks!

Yes, that is my setup.

Dave S

I haven't done this in months because the Sun has been so quiet. Just had a quick session when I saw this modest prominence today.

Dr. Robert Stein, professor of Physics and Astronomy at Michigan State Universe has long envisioned a day when he could use supercomputer programs to "see" through the roiling surface of the sun and glimpse its dynamic interior. He describes his quest and offers ideas about what drives th...

Nice images. I think that pencil-thin filament is the thinnest I've ever seen.

Dave S

Really great prominences!

Dave S

Finally had a clear morning after a couple of weeks of cloudy ones and got to see what the Sun was up to and got photos at three focal lengths with the LS80 and TEC160: FullDiskReducer_Sun_111034.jpg FullDisk1X_Sun_110149.jpg EastProm_Sun_094243.jpg SW_Prom_Sun_102955.jpg AR12687_Sun_100711.jpg

Excellent!

Dave S

Perhaps some people from the forum who donated were not identified as being from the forum? Different email addresses or whatever?

Dave S

Thanks!

I always struggle to get even illumination with my LS80 DS2.

Dave S

Welcome, Hans! I look forward to seeing your photos as you progress

Dave S

Narrower bandwidth and higher focal ratios will generally exacerbate the problem. And it will be different for different cameras. So putting on the DSii will usually make it worse, and putting on a barlow will make it worse.

Dave S

Nice! You got sharper images than I did.

Dave S

I also had that happen and Lunt sent me a new BG glass.

Mine clouded over after I had left the scope outside on a high heat and humidity day. At the time, I wondered if condensation was the cause of the crud.

Dave S

I was able to get some frames before the clouds moved in.

Really great hi-res prom photos!

Dave S

That's an amazing, dynamic, beautiful shot, Valery

Dave S

Thank you, everybody! I was really lucky to catch that prom.

Dave S

Wow, awesome set of images, Lou!

Oh wow, that's awesome that you caught the evolution of the big looper!

This has to be one of the most spectacular prominences ever!

You DID get it all in one shot! Very nice!

Dave S

Great catch! That's an awesome multi-loop. I'm out capturing frames now.

Dave S

Nice! I'm glad someone caught that one. I had clouds come in before I saw that on GONG.

Great catch, perfect transit!

Dave S

Great shots and detail.
Nice catch on the animation.
I was taking several shots from 18:47 UT to 19:10 UT that look just like the beginning of your animation to the point when the filament goes away.

Dave S

I braved the 100F temperature and went out at mid-day today for a few sun shots in bad seeing. I guess I just needed to get some images today. It was hot!

There were nice proms all around. This is the first one I processed:

Very nice prominences set

Dave S

Thanks! Derek, it actually has a lot of tiny hard dust spots that concern me. It came out of the box like that. I suppose I'll have to try cleaning the cover glass.

Dave S

It's a quiet Sun today but I'm playing with the new camera again. This is taken with the LS80 DS2 and the Basler acA2040-120um at native focal length of 560mm. It fits!
