Playing with the manual settings on the HX5V again. The bulb is a 60 watt incandescent and I adjusted the f-stop and exposure time so the details could be seen.

Another diagram for the Multi-Plane Camera. Note the rather excellent hand lettering. Also, the corners on the matte are perfectly angled. Attention to detail! Also, something to do with filaments
BEST VIEWED ON BLACK.
playing around with a plasma ball.
special thanks to Christine for the extra pair of hands.
Edited SDO image (one of the most famous it has taken) of a huge filament from the sun, several years ago. Processing variant.

What keeps these filaments attached to this galaxy? The filaments persist in NGC 1275 even though the turmoil of galactic collisions should destroy them. First, active galaxy NGC 1275 is the central, dominant member of the large and relatively nearby Perseus Cluster of Galaxies. Wild-looking at visible wavelengths, the active galaxy is also a prodigious source of x-rays and radio emission. NGC 1275 accretes matter as entire galaxies fall into it, ultimately feeding a supermassive black hole at the galaxy's core. This composite image, recreated from archival Hubble Space Telescope data, highlights the resulting galactic debris and filaments of glowing gas, some up to 20,000 light-years long. Observations indicate that the structures, pushed out from the galaxy's center by the black hole's activity, are held together by magnetic fields. Also known as Perseus A, NGC 1275 spans over 100,000 light years and lies about 230 million light years away. via NASA ift.tt/2oxl0Ts

A filaprom is a solar prominence that snakes its way over the limb (edge, in the photo) of the Sun -- as at mid- to lower-left in this photo.
There's also a nice sunspot or two and a moderately large active region (mid- to upper-right in this photo. I think these are sunspots 1344 and 1341.
Photo made using a 640x680 monochrome camera from The Imaging Source, and one of 3RF's 90mm Coronado h-alpha solar scopes at Comanche Springs Astronomy Campus.
Only the upper half of this photo has been post-processed. This represents the best of about 900 frames (about one third) of one of 4 AVI files I shot this morning. A full-up processing run on each of these files takes the laptop about 30 minutes, so more files are to come later today or perhaps in the wee small hours of tomorrow morning(!).
Nice Sun today, for sure~
Processing details: Registax V4, with 13 alignment points spread mostly along the filaprom and a few scattered among the active region ... basically the upper half of the image. Limited to half the aligned frames per alignment point (about 470 of 907 for each) with a 50-frame created reference frame processed with minimally agressive Gaussian wavelets.
Version that's processing now uses about 1/3rd of the available frames, with 29 alignment points spread across the middle third of the image, and roughly twice as aggressive Gaussian wavelets. Should make a nice comparison.

R7s J78 halogen tube linear (78mm) 150w. The filament has become so distorted it is starting to melt it's way through the glass.
