Notes

The data was gathered over the course of four days, The first saw such poor sky conditions that only one frame was retained. The sky conditions on the final night were infinitely better. The revamped 200PDS is doing great work particularly with the new CNC spider which has improved the diffraction spikes enormously (though not so evident here).

The second frame on the second night was lucky enough to capture a streaking meteor at a perfect position in the frame. The stacking process removed this but extracting it from the raw frame in question with the PixInsight GAME script allowed it then to be reintegrated into the stars frame before merging with the starless processed image.
