First look at the new sunspot. Need to do something about the uneven elumination.

Very nice image. Are you using a tilter at all?

Beautiful image. The sun spot is fantastic! The elimination is not that bad. I was having the same problem. I started moving the image around until I found a good spot to photograph as Marty suggested. I have tried a tilter yet because there are none available for sale.

No tilter, moving around is worth a try. And maybe flats.

Oh, a flat should clear up the problem. It's best to get into the habit
of always doing a flat.

Drat! I was just going to get the 80 out and the clouds rolled in. looks bad for the rest of the day.

You can also try rotating the front element to change the uneven illumination.

Brilliant image. I agree with others here, a flat would be the easiest way to even out your illumination. You can take it against the bright sky away from the sun.

Nice image overall, I hope the surface action lasts until I have clear skies, maybe tomorrow

Thanks for posting the image. Today is the best solar day I've witnessed since buying my LS80 DS and I really came to appreciate every bit of the aperture this morning. There were lots of details in that spot area, as well as the other ARs. I saw a circular peace sign in the plage next to the dark spot and another larger, fainter, similar 120° radial in the magnetic swirl. That thin, sharp dark filament looked a little like an integral sign.

David , Glad you had one of those days.
Its great when you get to utilize your equipment to the max.
Im hoping for tomorrow and Sunday here.
By the way , the CN people fixed my account so I can now see everyone’s signatures and get to check out all the equipment list there.

I need a barlow. I'm getting days where I can go past the 7.2mm limit of the Lunt zoom. I had the 1.6x that came with the WO binoviewer until I returned it. I'm thinking another of those or a 2x. Then the limit is the shake of the mount on the best days and seeing the rest of the time. I'm going to order a stool so I can set up close to the ground to get rid of some of the shake and save my back a little. I'm still loving the detail, even at lower magnifications.

Great looking disc Dan.
IMHO, as long as you're not loosing detail in the bright area, the unevenness can give a nice rounding effect, especially in colour. (It is a big sphere after all.)
All the above suggestions are good as well, and a flat will do the trick, just one more capture to process.
Looking forward to seeing more of your images.
I heading out in a few minutes, looks like I've got some good seeing here.
Thanks again Dan.
