Description

A crop of the whole frame, showing details of the region around AE Auriga. This is a composite of two stacks, one taken at F:2.8 to capture the broad extended background, and another at F:8 to capture clean star images. The stars in the image are pristine down to mag 15.

At F:2.8 the Canon 200 mm FL lens produces very comatic star images, and it is difficult to reach simultaneous focus on R, G, and B. But a fast lens is needed to capture low brightness extended regions. At F:8 the lens produces very clean star images and essentially no background.

This image is a composite stack of 5 x 300s at F:2.8 and 5 x 300s at F:8. The camera is a stock (unmodified) Canon EOS 6D. All exposures were unguided.
