Description

A two-panel mosaic showcasing the extensive dust across the celestial pole and around the M81/82 group.

A fun commissioning project for my new widefield rig, based around the Sigma Art 40mm and QHY268M. Setting up a new system is never simple and this was no different, with hours of painstaking tilt adjustment to give acceptable corners with the lens. I still think I could improve on what I ended up with but as the sensor is only APS-C it is less critical.

The final result contains approximately 27 hours of data.
