Astrophotography

[Shadowy Man]

If people stopped launching shit tomorrow, it would be hundreds or thousands of years before earth's skies would be devoid of naked eye visible trash.

Low earth orbiting satellites don’t last that long without boosting altitude. Even the ISS and HST have been boosted multiple times. I think your time scale is tens of years perhaps unless you want it to be *perfectly* devoid.

The reason I recalled the above, was that there's a FB group of astrophotography, and much of the discussion is about software and different techniques for removing streaks.

Hadn’t posted any of my shots for a while. This is NGC 4236. A galaxy in Draco. This is 80 3 minute subs for 4 hours of data. Telescope was an Explore Scientific ED 127, with a 0.7 reducer/ flattener. Mount was an AM7, and using the ASI air. Stacked with 30 flats and 30 darks and processed in Pixinsight. Had to redo it a few times.

Taken at the Bortle 1 skies, zero light pollution area of the Needles in Canyonlands, Utah. Amazing skies.
