Description

New method of exposure using high gamma value, 5ms exposure time, minimal gain to achieve 80% histogram fill without clipping highlights/data to the right. 6000 frames, 101 stacked to get best high signal to noise ratio for a hard histogram stretch with less noise (more stacking would be better, but in challenging seeing, it's not possible to always get large stacks of quality data!). The single data set then is worked to produce a surface and limb/prom image that is then made into a composite. The point is to reduce acquisition time by half, and capture good seeing for both surface & proms at the same time with less gamble when imaging at large scale like this.
