Hi James,

You’re welcome. On the baa-comet forum Nick Haigh outlined the workflow in DSS for comet stacking. This is also what I use.

To minimise saturating the coma yet bring out details in the tail you use the Luminance tab. Use your mouse to draw a box around its head and part of the tail, then gradually tweak the pairs of sliders for Darkness, Midtone and Highlight, each time clicking Apply to see the change – or Reset.

This is finicky work – it’s almost a Dark Art – subtle changes in the values can make a big difference to the image.

I’ve taken some screen shots of my steps in DSS, so I’ll retry comet stacking (stationary stars+comet option) and send you them (offline) in a PDF, either later today or tomorrow.

Cheers,

Alex.
