Sergei Golyshev (AFK during workdays)
Meticulous deconvolution of the Moon
Aquisition time: 18.09.2013 21:09:00 MSK (GMT+4).
Image orientation: straight, it's obvious
Equipment:
Canon EOS 60D (unmodded) in prime focus of Vixen VMC110L Klevtsov-Cassergain telescope riding Celestron CG-4(Skywatcher EQ-3) equatorial mount kustomly(sic!) attached to Vixen SX half-pillar over Vixen SX tabletop tripod over MDF plate over window-sill :)
Aperture 110 mm
Focal length 1035 mm
Tv = 1/30 seconds
Av = f/9,4
ISO 200
Exposures: 10/20
Processing: +1,17 EV added and contrast curve set to "Linear" in Canon DPP, images exported as 8-bit monochome .TIFFs and assembled into .AVI in ImageJ. Movie was sliced into four overlapping segments, which were stacked in Autostakkert2, stitched back in Microsoft ICE and deconvolved (Richardson-Lucy algorithm, Cauchy-type PSF, 3,1 units, 5 iterations) in AstraImage 3.0. Final touches in Photoshop.
Note: it seems that 2400x2000 pixels is the upper limit for resulting picture size in Autostakkert2. Bad news...
