M101 - The Pinwheel Galaxy


This nice face on spiral galaxy is 27 million light years distant and has a magnitude of 7.9. It is also known as NGC 5457. I find it interesting that the core is offset from the center.

The image above was taken remotely with the equipment in New Mexico on the nights of 05/27/22 and 05/31/22. The imaging system was a Canon 200mm lens and a QSI camera. It is an RGB composite (as detailed below) with a total exposure time of 6.5 hours. All processing was done with PixInsight.

Previous best. Really just an experiment.

Two 2 minute exposures were combined to create this image. The LX200 was operating at f/3.3 with the 416XT camera.  Taken on July 23, 1998 at the Table Mountain Star Party.
