Hi Mike,

Got a technical question for you. When you do your LRGB combine do you normalise the RGB or the LRGB first?

I have been finding using CCDstack and Baader and to a lesser degree the Astronomik filters that unless I do a normalise I can get weird colours.

With the Baader it is more pronounced and I have lost some images due to weird colour combines. Today I was processing the Vela SNR and I kept getting weird electric blue colours until I normalised not only RGB but the full LRGB then the colours were fine.

Its enough to make me go back to Astrodon filters and risk the reflections problem.

Greg.
