The raw file is the unprocessed image you stacked and pulled out of registax. I wanted to take a stab at processing your nice capture !

looks great to me

terrible conditions while testing a new, 2" Siebert optics 3.5x. This barlow/telecentric has some great potential to be my new preference at 393nm, and my first light first impression is a good one.

so i have been keeping a close eye on this https://sdo.gsfc.nasa.gov/data/latest48.php?q=1600 This circle ridge feature is absolutely without a doubt captured on SDO aia1600 as well, so this is very real. I wonder if i was just bandpass tuned to a unique material wavelength inside of the sunspot that is normaly not thought about. My filter is close to 0.5 angstroms, but the wavelength is currently unknown because of the barlow placement currently. Could be calcium, could be iron. Could be silicon, aluminum. Conclusively i would say yes that pure atomic metals are spewing out of the sunspot core, and various elemental densities separate via magnetism then a pure slag/slush forms the circular perimieter where it maybe is hottest because it is freshly projected material. (projected from under the sunspot)

When i stack images in autostakkert, i select the "Expand button" so that i get maximum file size out of the stacking. You can load up the files in pipp if you want to crop them all to be the same size , but throwing a .tif raw file in autostakkert will not accomplish anything. The files need an image processor and aligner to be used.

www.gifmaker.org is what i use You can align all the final stacked images with imppg , it has that feature in the file bar.

Thanks, ya i used to have sdo aia1600 and sdo aia1700 to compare using the 4096 download data from here https://sdo.gsfc.nasa.gov/data/aiahmi/ But that has been disabled. I will look at helio viewer and see whats hiding in there.

dont focus so much on "good or bad", just keep the camera rolling!! Get some of those ellerman bombs animated. You are ready for this. Just 10 minutes of capture time is all you need. Set fire capture in autorun mode, enable to 2 second delay, and adjust your file capture size to 3000 frames.

Great images and i agree with nigella, dont rely on topaz for the ai deconvoltuion- it does not have the required image data to support our field currently. Topaz is amazing for converting .TIF raw processed data into .mkv and .mp4 file upscaling to 4k and 8k. Other than that instance I would always use Imppg to process before using anything in topaz labs suite.

All I can do now is give everyone the raw files to process for themselves. So here is the raw folder from autostakkert. 11-7-2020 umbral ring data.zip

The problem is very few people on earth are making these animations like i do, and even fewer people own a calcium filter My filter is very unique, in that is 100% customized. only one other person on earth owns anything similar. He lives in Singapore and has had monsoon season, so very few images are coming from him at this time. I am not aware of any online timelapsed daily calcium images at this resolution outside of the dutch open telescope, and that does not seem open for my access.. You can sort of see where the rings are in most of the recent images however. They are are defined differently because of different areas of the chromosphere/photosphere shown in my data. Here is a previous image from the 5th, the ring is there it just isnt has defined like it was on the 7th. i did find this image below on spaceweather.com posted by allesando bianconi. he images at high resolution and there is a secondary beach pattern is in his image as well. However you can also see the difference in our filters/ telescope. 200mm versus 127mm... , unfortunatley no animation from him. . However, i am going to still be inclined to accept it may be a camera artifact. I will try to process the data again to remove it. But, i do like to accept that its a rare instance of something unique to that day. https://spaceweathergallery.com/indiv_upload.php?upload_id=169516 here is anote worthy image from alan friedman who is pretty famous for imaging, the beach is there as well. https://spaceweathergallery.com/indiv_upload.php?upload_id=169520

Observed on 11/7/2020 , a rare double umbral annulus ridge was captured in calcium light just outside the umbra core pulse. (the newton ring perimeter pattern seen along the umbra edgel

A rare sight Captured in calcium light, observed on 11/05/2020

well now i am perplexed. I processed the images several different times and stacked several different methods. Those contrasty, artifact like rings inside the sunspot are real, it is some kind of double anulus ring at the edge of the inner penumbral perimeter. (it looks like a pair of newton rings inside the sunspot core) I have never seen this before in all my 10 years of imaging, and 15 years of watching the sun. I would like to still believe these are artifacts from my camera setting or processing; however they are in the raw file and have an apparent "beach like" crest wave associated with the pulsation of the core within the animation. There is a flow of pressure actually pushing outward from the center of the sunspot core, toward these rings. It literally is like a beach! Here is pure evidence and correlation between the inner core outflow, directing the curious ring/ridge .

Could you post a raw file of what you captured?

I have sorted out some of the issues, and the attached data is on the comment below.

This current configuration is an explore scientific "firstlight 127mm x 1200mm achromat" https://explorescientificusa.com/products/fl-ar1271200maz01?_pos=4&_sid=04fde915d&_ss=r There is a meade 2x triplet barlow in the focuser, before all of my filters; threaded directly onto the nosepiece of my 2" skybender. The camera is placed 165mm after the barlow, which brings the system magnification to exactly 3.3x. this is very close to critical sample on the IMX174 sensor 127 x 3960mm basler usb3.; aca1920-155um , and a aca720-540um https://www.baslerweb.com/en/products/cameras/area-scan-cameras/ace/aca720-520um IMX287 sensor Pixel Size (H x V) 6.9 µm x 6.9 µm https://www.baslerweb.com/en/products/cameras/area-scan-cameras/ace/aca1920-155um/ Pixel Size (H x V) 5.86 µm x 5.86 µm Because the filters are now operating inside of my barlow, i have lost most of my tuning ability . it shifted my desired wavelength of everything in my filter train by an unknown amount. I do recommend useing a meade 2x telenegative barlow at 2.25x however. anything higher stretches the image. Televue 2.5x powermate sucks regardless of placement.. , explore scientific 3x tele-extender sucks as well..

Frames captured=7000 capture Duration=13.419s Total animation frames = 60 FPS (avg.)=521 Shutter=1.802ms First frame start time = 201938.537 - First video capture at ‏‎2:19:38pm last frame start time = 203450.293 - Last video captured at 2:34:36pm Total stacked images per animation frame = 1000 Total video capture duration time 900 seconds . 60 videos x 1000 stacked = 60,000 total video frames extracted from 420,000 total frames captured (best 7% in autostakkert) This should be enough info to determine the integrated frames per second. It seems somewhere in the ballpark of 115-120 it is still 15 minutes of elapsed total time however,

I am thankful for the unseasonable weather and imaging i have getting. This is shot with my super high speed camera. If you pay attention to the sunspot penumbra you will see a little worm like appendage retreating into its core. Also notice the pulsating center. Captured at 500fps. and the rest of the film captures that larger fibril get sucked back down the drain. .

very cool

nice!

A very highresolution capture i made on 11/3 .

Changed up my setup to a meade 2x apochromatic triplet barlow today. I also changed some distances up and tilted some things. While i am happy with this magnification, my moving of things has caused a drastic change in my bandwidth or wavelength. Not sure yet. interesting barlow, and i am operating this new triplet barlow at 3.3x. which is about 165mm away from its last lens element. I was lucky to get a great captures today! This ribbon prominence was pretty much invisible, and hanging out with the new sunspot. i did not know it was there until after i ran out of disk space. The new sunspot pretty inactive currently, but it seems menacing at his scale. I will continue testing lenses to find the optimal element for high res with calcium imaging. While this seems really good at first glance from a picture pretty perspective, i suspect there is an issue using this barlow because my tuning is so different. link to a longer set of raw files. unprocessed. feel free to share or create what you want with it. https://drive.google.com/file/d/1lnwDwBucOxyoSIGXgr8aXR1mdv9ra6l4/view?usp=sharing

These are Canadian geese; and are migrating for the winter. They are common around the area after corn harvests before flying further south. First time ive had such a close encounter like this however, when i saw it on screen it went by so fast my first thought was space ships for sure. CApturing at 150 frames per second thought made a great sillouette play however. I sware one of them moves its head and looks at the active region?
