Comet C/2023 A3 Tsuchinshan–ATLAS over the Pacific coast.

This is a composite.

I made it out 5 nights last week to observe the comet. Here is a stack of 20 sec frames using the built in astrotracer feature on the Pentax K3 II.Pentax DSLRs have a magnetically floating sensor, allowing the sensor to move in sync with the earth's rotation, directed by the built in GPS in the camera.

There is a healthy bit of 'movie magic' applied to the processing here, going for more of a pretty picture than scientifically accurate.

Hope you like it!
