Description

Imaged from my driveway Bortle 6-7.

Of interest is the image was taken with an incorrect back focus  that resulted in elongated stars in the four corners.

This has since been corrected by addiing 1.5 mm to the total back focus between the field corrector/ flattener and the sensor [ total of 17.5  mm sensor depth + 21 mm filter drawer + 16.5 mm spacer = 55 mm. It had been set at 53.5 mm].

This pre-dates BlurXTerminator.
