Description

This is the first part of my mosaic project for this autumn/winter! My plan is to image the complete Cepheus constellation with my Samyang 135mm. This was the first test to see, if my camera settings are sufficient to get all those tiny details. At the moment, every tile consists of 60x 30s. Maybe I will increase that time more.
My goal is to take the complete mosaic in one single night. There will be several follow-ups to this image!
