Laboratorium Solaris: meet the Moon

Target practice. Hit 2 out of 2 :)

 

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

Processing:

The Sun:

1) stacking in AS!2 2.3.0.21alpha;

2) stacked image was used to make two components - one by applying convex curve for proms, and one with concave curve applied - for the disk details;

3) both derivative images were deconvolution in AstraImage 3 PRO (Richardson-Lucy algorithm, Cauchy type PSF, size 0,9 units, 6 iteartions);

4) high-pass filtering, masking, blending and stichingcollage-ing were made in Photoshop.

 

The Moon:

1) Raw images were converted to linear, brightness adjusted to +1EV, color set to monochrome, the sharpness and NR set to 0 in Canon DPP;

2) Images were pre-cropped to 1024x1024 and exported as 16-bit .TIFFs and stacked in AS!2 - I just discovered that it can consume image sequences. One just need to drag-and-drop them into main screen instead of using Open button :)

3) deconvolution (Richardson-Lucy algorithm, Cauchy type PSF, 0,9 units, 6 iteraion) in AstraImage Pro 3;

4) high-pass filtering and collage-ing were made in Photoshop.
