WR 134 from my „Jade“ observatory

This object I imaged twice, once in Krefeld with my „Sterntaucher Observatory“ and now in Varel with my new equipment on the second pier „Deep Sky Pier“ in my „Jade Observatory“.

WR 134 is a variable Wolf-Rayet star surrounded by a faint bubble nebula in the constellation of Cygnus.

This is the image from 2025. Data calibration, registration and the final processing was done with PixInsight. The result was as follows:
