About this image

I set out to show how it's possible to capture deep sky immage with basic equipment on untracked mount.

30 x 5s exposures at 10,000ISO reduced noticeable star trailing.

Lights, dark and bias frames were calibrated and stacked with Astro Pixel Processor and further processing in Pixinsight and Affinity Photo 2
