Comet 2017 T2 Panstarrs

This is the result of  12 x 60s subs in each of luminance, red, green and blue light. There was a 10 sec pause between each image to give more time for the comet to move (requirement for the processing technique). According to the method I was following, the total data time should be under an hour because comets are such dynamic objects

I was trying to follow Bernard Hubl's method but in the end had to use Deep Sky Stacker and its 'comets and stars' function. 

For Luminance  I produced an image of the comet only.

For R, G and B I produced an image of the comet plus stars. The channels were combined in PS

I stretched both the L and the RGB images in PS and then combined them. 

 The trouble I found with this is that stretching to show  the faint tail with the limited data meant I also developed the streaks left by the stars. My knowledge of PS is not up to removing  broad faint streaks but leaving the tail.

Anyway, for better or worse:
