Processing Comet and Stars using APP Starnet++ and photoshop

This blogpost is about how to get both the comet as the background stars processed sharp.

A video I used is the one from LuckyBudd : see this link 

What's needed, or at least, what I used :

    - AstroPixelProcessor (APP)

    - Starnet ++

    - Photoshop

1) APP

    a) Stack images of the comet using registration mode "Comet/one star" (Picture 1)

    b) Redo integration with "MAD" setting (Picture 2)

    c) Redo stacking using registration mode "normal" and restart integration (Picture 3)

2) Starnet++

    a) Remove stars using Starnet++ of Picture 3 (Picture 4)

3) Photoshop

    a) Load Picture 3 and Picture 4 and "layer" them together

    b) Use "Image", "Use Image" and substracted (Picture 5)

    c) Load Picture 2 and layer Picture 5

    d) Use "Layer", "Layer Style" and linear blending (Picture 6)

Edit Picture 6 as a end result.
