Coronado SolarMax II 90 DS. 32x, 44.5x and 88.9x ( Ha )
I can see 4 disturbed regions on the disc. The largest is AR12822 in the north-central part of the solar disc. It's ragged plage is easily seen as is it's largest spot and others at higher power. I can see a couple of thin filaments SE of the spot. In moments of really nice seeing I can see the spicules spread out around the active region. I notice no flaring activity. Well to it's south I see AR12823. I see a nice thin looping filament below it's plage and spot. The two other areas are just mere disturbances in the SE and SW. I see almost no other filaments on the disc. Certainly nothing of any size.
In single stack I can see all the prominences shown on the GONG Big Bear and CerroTololo Ha images. The best one is on the SW limb and shows nice detail looking all like a burning flame.
The mottles look really nice today and hint at fine detail during moments of nice seeing. I can also easily see the spicule layer with the taller spicules poking up above the canopy like emergent trees out of a dense forest.
Celestron NexStar 102GT w/Altair wedge and 540nm filter. 55x, 110x and 200x! ( WL )
White light was certainly the star of the show today. The resolution in the 102mm refractor during times of good seeing was among the best I have seen in white light to date. I actually could slightly out resolve the SDOHMIc 4K image! I can see every spot and pore shown in the SDO image in AR12822. The umbra has a very ragged, lumpy rough edge. The Penumbra circles the umbra except for being absent on the NE side of the spot. I can easily see the outward radiating pattern in the penumbra! An arc of spots/pores lie east-southeast of the main spot with some stragglers below the main group.
The single large spot of AR12823 looks almost artificial! It's large and very dark and at a size which usually sports a penumbra but lacks one. And I can see three very tiny granule-sized pores to it's SE!
The granulation is NOT just fine rice grain motting today. At high power, 200x I can see them individually. They " magically " appear sharp and detailed one moment with the seeing and blur the next. But when they are clear I can see each one, all so very numerous. Some are also a bit darker than others. Only a handful of times have I ever seen the granulation like this. If I had a large refractor or a Celestron/AiryLab HaT and lived in an area with really nice seeing Ha would have serious competition with white light observing! Can a HaT system be used in white light? One probably cannot use a wedge though :-(
I did image today. I'll put those up when I process them. I hope they turn out. My visual skills far exceed my imaging skills.
Carpe Lumen!

I am with you all the way that WL granulation is the most breath taking view ever
