Description

This image combines different focal lengths.

IFN and FOV are from 700mm. The image was scaled to 2m scope image (not the other way around).

Then the galaxies from RC 10'' were layered on it removing original low res objects.

(M81 can be seen in the gallery). This is the reason why the image is so large.

Total integration time is around 45 hours (25 hours for M81 from November and 6 hours M82 Lum)
