Cepheus Dust

This time I really pushed my setup to its limits: a wide-field view of the dusty regions in the constellation Cepheus, focusing on three stunning deep-sky subjects: LDN 1251, LDN 1235, and VDB152.

Such a wide field was made possible by the combination of the RedCat51 and ASI6200MM full frame camera, which allowed me to capture all these objects in a single frame, without the need for a mosaic.

 

The idea came from having just a few days under a good mountain sky , I wanted to bring home as much as I could, and I did. I would have loved to go beyond the 11 hours of OIII, 12 hours of Hα, 6 hours of Luminance, and 6 hours of RGB, but the weather was a relentless adversary this time.

 

This image is also special for another reason: it’s my last one with the RedCat51. After more than two years together, my “red cat” will soon move to a new owner. It has been my inseparable companion, light yet precise, and has followed me through many nights under the stars.

Switching to a full frame ASI6200MM,a fantastic but demanding camera, pushed me to upgrade my wide-field setup… and new things are coming soon.

 

For the processing, not only PixInsight: Photoshop has now become a stable part of my workflow, perfect for quickly and effectively refining those small details that make all the difference.

 

Clear skies, everyone!
