Description

Light collected on multiple short sessions between August 29 and September 02 2023.
Overall it is just about an hour and a half without filters, so not much nebulosity is present: more or less equivalent to a similar exposure time with an UHC filter from the city (Bortle 8).
Except for the many more stars.

Title: Less starry to enhance nebula

Description: Applying the "Isolate" module of StarTools it was possible to make the shape of the Crescent Nebula somewhat more evident. This also implies dimming the background.
