Photo description / processing

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 and no noise reduction.

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

Thank you!

The black background looks nicer, in my opinion. A light background and a softer image are better for nebulae, while a dark, more contrasty image is just right for globular clusters and star clusters in general. And what is that arrow in the image pointing to?
