Single 60s exposure used for setting up imaging on the flame nebula shows a short rainbow-style trail which I think could be created by a meteor since airplane lights or satellites behave different. regarding track, style and color. Internet says that non-straight meteor trails happen (in about 1% of meteor sightings), either zig-zag-style or sinusoidal, and coloring also matches that of pictures I found on the Internet.

Since there are a few single hot pixels visible in the image, I first thought that this might be a larger sensor failure because of the relatively sharp colored pixels; but with a very short timeframe of the meteor event (small grain, few milliseconds?) that would be possible to have that sharp edges as seeing blur would not have a chance.

Any other ideas what that rainbow arc could be?

P.S.: Please ignore the optical quality, I made beginner's re-assembling mistakes by fastening screws to hard on primary and diagonal, resulting in astigmatism and coma

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
