Border of the yellow-green zone. The image was taken during moonlight. Using a 2" UV IR Cut filter.
47 lights. Exposure 300". Gain 100. 30 biases. 13 darks. 30 flats.
Unreliable guiding information, error 0.21-0.5".
Polar alignment accuracy 1.07'.
Either the mirror is over-tightened, or there's an issue with collimation. It also looks like it was shot from the edge of the frame and cropped. And the exposure data can be added to the technical information.
I only noticed after publishing that I could add the exposure data to the technical information.
The collimation seemed fine, which can't be said for the record-breaking guiding (0.21-0.36" up to 0.5") and the not-so-great final result with trailed stars. It seems someone somewhere deceived someone.
