Sky at Night Magazine - - SUMMER OBSERVING -

Now we need to take the three videos and process them in soft­ware such as RegiS­tax. RegiS­tax can fil­ter and stack the best frames from the promi­nence and disc videos as well as wave­let sharpen the still im­ages that this process pro­duces. It can also cre­ate and sub­tract the flat field frame. To cre­ate a flat field, open the flat field video and use the Flat/Dark/Ref­er­ence > Cre­ate Flat­field menu. Save the im­age this creates and ap­ply it (us­ing Load Flat­field) to the two pro­cessed main im­ages.
