Solar granulation

My images

A session aborted by cloud arrival (20150610) then missing sunspot 2365
Seeing not bad ...

Of course those are not great images from granulation but it is what I can get with a standard LX200GPS.
Extraordinary images can be obtained with top equipment, in good seeing with specialized solar Newtonian telescopes, by experimented solar astrophotographers as here.

Sun : FujiFilm HS10 + 1.5x extender + visual solar Baader mylar. 6 x Fuji RAF RAWs aligned with PiPP & RegiStax5 in CG mode.
Granulation : LX200GPS 12" + 2.5x Barlow (FL = 7.500mm) + Baader D3.8 solar photo filter + Baader Continuum filter + 2 x Baader IRCut + ASI174MM camera at full size, gamma 0
Each image result after AS!2 (25% best) of a 1 min 8 bit SER file (Firecapture), processing Astra Image LRD 150'17i and levels 9456..43862
Bonus:
Single frame
Clip available in XVID compression 3 showing seeing (100MB, right-click to download)

 

An interesting session (20150518) click for full size

Acquisition : FireCapture 2.4
Focusing is difficult !

Registration AS!2 (10% best kept for top and middle images, 30% for bottom image)
Enhancement of features : Astra Image 3.0 Lucy Richardson deconvolution (Img1=LRD070'13i, Img2= LRD080'13i, Img3=LRD140'6i then stretching)
Colorization GIMP2 (Map, sample colorize from another Halpha picture)

Note : The sky was perfectly clear but is was a windy morning ! I had to wait for some rather quieter moments to start captures.
Also the rolling shutter of the ASI120MM made strange wobblings at high magnification (with the 2.5x Powermate).
It is the reason I switched for the ASI174MM which has not this problem.

What king of quality in the originals captures ?

With 2.5x barlow : A good frame ... Only part of it are rather good !

The beautiful lacework of sunspot 1515 ! This is my best picture in white light, I guess because the sun is very high Summer solstice ...

Even more penombra resolution after putting lots of APs on the sunspot ...
