Laboratorium Solaris: seeing is believing
How can we call this thing in the bottom left corner of the frame - the sprite? The ghost? The CME?
I have got dynamic range - 12 bits, no kidding! - but no luck with flatfielding yet...
WARNING! Sun is dangerous, use proper filters for observing and imaging!
Aquisition time (start of the session) : JD2456852,72667824 (14.07.2014 09:26:25 MSK).
Image orientation: west is down, I think
Equipment:
QHY5L-II monochrome CMOS camera via 2x Barlow lens on Coronado PST riding tuned motor-driven Celestron CG-4 EQ mount set over Vixen SX tabletop tripod and SX half-peir.
Aperture 40 mm
Native focal length 400 mm
Effective focal length 800 mm
Tv = 2 ms
Av = f/20
ISO NA
Gain 23 out 1000
Software: FireCapture
Exposures: about 400/800
Processing: camera was running in raw mode, producing 4096 shades of gray. The movie was saved in .ser file. Movie was processed in Autostakkert!2. Resulting image was subjected to Richardson-Lucy deconvolution in AstraImage 3.0 (Cauchy type PSF, size 2,7 units, 5 iterations).
High-pass filtering was made and contrast adjustment were done in Photoshop.
Note: the Newton's rings are the primary problem now.
