Laboratorium Solaris: clean up!
After the eruption of "The Great Wall of Fire"...
Intended for full size viewing - there is a lot of subtle physics hiding inbetween spicule pattern and a ghostly cloud-like prom hangs near the "equator" on the left side of the image. Inset shows it with more contrast.
Safety first while watching the SUN!

TIS DMK23U274 via 2x Barlow lens on Coronado PST on Celestron CG-4 with motor.
Mosaic of seven plates, each 25% of 600 frames taken at 1/200 per frame, Gain 1,79 dB.
Capturing software: TIS IC Capture.
Datasets were stacked in Autostakkert!2 with dark and bag-flat, white reference point added in PS*, images were deconvolved in AstraImage 3.0 (Richardson-Lucy algorithm, 0,3 pixels, 9 iterations) and piece-meal stitched in MS ICE**. Complete image was wavelet-sharpened in AstraImage 3.0 (1-10-15-5-1) and touched-up in PS again.
*One of them is still here, near the bottom left corner.
**MS ICE can stitch the whole set at once, but it does it rough and dirty. Stitching panel-by-panel - say 1+2, when summ+3, when 4+5+6+7, when summ+summ -creates far more better final product.
