Sunspots 2740 & 2741

Technical card

Resolution: 1013x1266

Locations: Home, Foster City, California, United States

Data source: Backyard

Description

Best 50% of 900 frames stacked in AutoStakkert.

Flat frames were captured by de-focusing the scope, and capturing 300 frames. Used AutoStakkert to create a master flat which was then applied to the 900 frame video, to remove dust bunnies and correct for the uneven illumination.

Final stacked image edited in PixInsight - used RestorationFilter and ATrousWaveletTransform to sharpen the image, and HistogramTransformation to stretch the data.
