One and a half hours on an F/7 scope — all I could get between the clouds.

TWO PROCESSING VERSIONS. The differences are obvious: one with a black background and one with a bright background and no noise reduction.

A request to viewers
Please, which version do you prefer — with a black background and tiny stars OR with a bright background and dim stars?

Thank you!
