Description

This is a mosaic completed with my modified 200mm lens. I opened it up and placed a circular filter cut from a pie plate into the lens at about the level of the mechanical aperture as I am not a big fan of diffraction spikes on my stars. The circular aperture makes it around F4.0. It is a 12 frame mosaic of 10min subframes with a minimum of 15 subframes total. I used to have to travel 4hrs to my parent's cottage to get remotely reasonable images, so I am very excited to see the potential of narrowband imaging off my raised back porch in a red zone. The original image size is >700Mb.
