Description

This image shows a number of beautiful nebulae in the constellation Cassiopeia: the northern lagoon (NGC7538, top), the lobster claw (NGC7510, bottom) and the bubble (NGC7536, centre left).
A beautiful cosmic and aquatic environment!

There are also other smaller nebulae (SH2-158, SH2-159...), two beautiful open clusters (notably M52) and a few planetary nebulae (one of which is clearly visible at the bottom of the image).

This is a mosaic of 2 images taken during the summer of 2023, using the TSA-102 at 600mm focal length and the Atik16200 CCD, which means that the final result is a wide field without sacrificing resolution.

The mosaic was created with APP, using the latest refinements made possible by BXT and GraXpert to ensure a high degree of homogeneity between the panels and stars before assembly. Processing was then made in SHO using Pixinsight, with the stars coloured in RGB.
