Description

The sky was clear, sometimes windy, but good transparency @ a dark location.

Let´s use the time to make an experiment, capture DSO during almost full moon.
- capture a object with enough brightness
- near zenit to reduce influence of moon light.
- use a low sensitivity setting on DSLR to get long exposure time per light (200ASA)-- 12min per light

Result: all lights have blue backlight, but quite good visible M97, and a lot of small galaxies in the background.

In future, I will make more small PN during moon brightness. at 200ASA the amp glow protection makes nonsense, that why you see the lines. Only a rotate like a rotating dithering would help.
