Description

Comet processing is, IMO, one of the most challenging. This is my attempt to apply some new processing tools in Pixinsight  to comet data. I used batch processing of StarXterminator to create the starless comet image. The 'stars only' image stack did not work well in my data. So, I used the conventional comet subtraction in comet registration to produce the star field image. 

To apply star color calibration with SPCC, comet coordinates at time of imaging had to  derive from Stellarium because the image was acquired from a DSLR on a star tracker.  The upward orientation is a bit unusual in comet image. However, I did it this way to display the dusty tail of the NEOIWISE comet.
