X2 flare on huge sunspot AR2192 in H-Alpha
(Oct 27, 2014 14h17+ UT)
Click on the Sun below for the giant,
115 mm diameter , 22 Mpixel image at full size !
you can also download an HD or an UHD images.
It took me a full work day of reconstruction just to assemble, feather and equalize manually this about 35 piece mosaic with PSP.
The aspect of the Sun shown is not far from the real one at the moment of the flare.
The captures where done with the PV 102/900 Fluorite, Coronado SM90 and DMK41 GigE ...
Each single image is the result of the registration & sharpening of about 20s of capture @ 14 fps, with Autostakkert!2 and the mosaic is wavelet processed with RegiStax6.
Colorization with GIMP2.
FLUORITE 102/900 ACQUISITIONS
Fluorite 102/900 Perl Vixen on EQ-G mount + Coronado SM90/T90 (90 mm diameter)
Electric focuser + 1.6x Antares Barlow + Coronado BF30 + DMK41 AG023 AS (GigE)
and just after a few shot of the whole Sun with the STL11000M
SBIG STL11000M whole Sun single 0.05 sec exposure (15h48 UT) showing acquisition zone
SDO movie from http://sdo.gsfc.nasa.gov/data/aiahmi/ ... Please chose HD 720p in controls and reload !!
EPISODE II (Nov,2 ... One week of fast PC work) :
About one hour acquisition with FireCapture
2.4.06 first part @ 14 fps second part @ 11 fps,
cut into 30 sec sequences (then not same number of frames in the 2 parts), 15 sec Nyquist time shift .
Segments saved using VirtualDub, Registration & convolution with AS!2 in Batch and Surface mode,
convoluted PNG to BMP conversion with Irfanview in Batch mode,
Registration (using filter gradient mode) & saving to movie with RegiStax5,
Final crops with VirtualDub (+ MSU filter). Presentation 130%.
Please chose HD 1080p in Youtube controls and reload !!

*** Note : all those videos are the same data (except MSU). You can if you know how to, load only one of them, open it in VirtualDub and change the frame rate before saving again. You can also export frames as JPGs , etc.
All in high quality video and visualisation speeds from 1 to 120 fps showing the scene with really different sensations (download sizes from 55 to 135 MB)
EPISODE I (Work of Oct 30, only up ramp of flare with longer 40 sec sequences) :
1400 s acquisitions with FireCapture
2.4.06, 20 s Nyquist time shift giving a final animation of 70 frames of
Segments of 2 GB saved using VirtualDub, Registration & convolution with AS!2 in Batch and Surface mode,
PNG to BMP conversion with Irfanview in Batch mode, resizing the results to the same size with CropCenter,
Registration (using filter gradient mode) & saving to movie with RegiStax5, Final crops with VirtualDub (savings in LAGS for works and XVID towards Youtube).
40 sec animation of processed AVIs / images ...
