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

TWO PROCESSING VERSIONS. The differences are immediately visible: one with a black background and one with a bright background without noise reduction.

A request to viewers:
Please, which version do you prefer — the one with a black background and small stars OR the one with a bright background and dim stars.

Thank you!
