Here is my work in progress automatic slide scanner project. There are several #freecad designed parts, some #blender modified parts, an #m5stack controller for my #legonxt motors. Next step is to setup my #canon mirror less camera and automatically scan and download the photos by python #gphoto2 to my #linux host and then process the raw files in #darktable.

Yesterday's #comet #astrophotography #timelapse - the weather could not have been better.

Unfortunately the light leakage from inside the house is visible on the window pane reflection despite my best efforts.

Source data: ~3h of RAW 15s exposures using #gphoto2 + #raspberrypi (20GB total). Processed using #darktable #cli (amazing!) into #jpegxl 16bit intermediary near-lossless frames (300MB total) into final 10bit #av1 social-media optimized video you see here, (~750KB). That's over 25000:1!
