Laboratorium Solaris: the exotic star

Lazy Sun of 19.07.2014 was dreaming of trees (on the left) and of clouds (on the right).

 

"Exotic star" is a term for the star remnant made of matter in uncommon state, like that of quark or electro-weak star (both hypothetical). Here it's just an exotic colorarion :)

 

WARNING! Sun is dangerous, use proper filters for observing and imaging!

 

Aquisition time (start of the session) : JD2456858,079433 (19.07.2014 17:54:23 MSK).

Image orientation: N/A

Equipment:

Canon EOS 60D (unmoded, but should be otherwise :) via Baader Planetarium Hyperion Zoom 24-8 mm MkIII eye-piece on Coronado PST on photo tripod.

Aperture 40 mm

Native focal length 400 mm

Effective focal length ~600-700 mm

Tv = 1/40 s

Av = N/A

ISO 500

Software: N/A

Exposures: 28

Processing: my usual approach to DSLR Solar footage includes conversion to monochrome in Canon DPP, pre-cropping images to 1:1 1800x1800 pix, painfully long export as 8-bit .TIFFs, assemblage to into stacks in ImageJ, stacking in Autistakkert!2 and deconvolution in AstraImage 3 PRO (deconvolution settings lost in time :( ). But! I have made three images from the stacking result - one unaltered, one with normalized (If = (I-Imin)/(Imax-Imin)) histogramm and one software overexposure. These three were somehow blended together through excessive processing in Photoshop in the end :)
