Description

This is my second attempt to create this photo. I combined frames I made in my backyard with frames I made in the polder near the river Lek. The photo is made out of 2:36 hours Luminance, 1:15 hours per R, G, B, and 2:30 hours H alpha., a total of about 8:45 hours.

L: 60 sec, R,G,B 90 sec, Ha 150 sec.

I used bias, darks and flats.

The processing was done exclusively in PixInsight.

I started this hobby Februari 2019. So I am in a learning process with respect to “everything” related to astrophotography. But I have the feeling I am making progress, so I am looking forward to the next season!
