About this image

I set this up in the Ekos Scheduler to run after another target, and went to bed: the first time I had done this. Next day I could see that clouds in the target area at the scheduled start time, 2024-04-22T01:06:11, meant plate solving failed and the job was temporarily aborted until 01:16:08 when the alignment succeeded and the sequence ran until 02:55:43, acquiring 1,000 frames. Robots, eh?

I photographed this a year ago on April 20 ... and on May 20 a star in one of the outer spiral arms went supernova. Just saying.

Yep SN 2023ixf is still visible in this image, glowing red at mag 17.5 V

Ah, so it is. Thanks for pointing that out, Robin.
