Description

This is my very first attempt to monochrome astrophotography.

Astrodon 6 nm Ha filter. Unity gain. -15 degrees, 1 x 1 binning. Only very basic processing: Image calibration with some darks & bias, no flats, some DBE. Still noisy. I will have to learn a lot of new processing stuff here.

Very limited transmission (high clouds). Still proud: Wow, what an amount of detail .... :-)
