Luna - single shot DSLR & old prime lens

[vineyard]

Hello,

Had a v quick go last night around midnight. Normal photographic tripod, Pentax K70 w old CZ Sonnar 135mm (set one click wider than f5.6) ISO 100 - put the camera into monochrome and used its pixel shift function (where it takes 4 photos in quick succession, shifting the sensor 1 pixel each time - I guess that increases resolution?).  Have put the images through a couple of High Pass iterations in GIMP.

3 images (all converted to JPEG for size) - a close crop, a full FOV, and then just for fun, Sirius peaking through some trees.

Cheers.

The Pixel Shift sounds like Dithering so maybe it will make for less noise and hot pixels

Yes it could be a nice proxy for that (although its not completely random since its always 1 pixel in set directions).  I will also try it when the camera is on a tracking mount to see what happens.

(There is also a "movement corrected" version of the PixelShift which should work, even without a tracking mount, for short-exposure objects at infinity like the moon where the object itself should not have moved by a pixel a camera sensor in say 1/80th of a sec - another thing to try!). Will report back once a chance ever materialises again w the weather!)
