Re: [APML] Creating H-Alpha Color Composites

[Jason Ware <jtw@galaxyphoto.com>]

Robert, I finally got around to reading this. I have been
using this technique for a while on my Scmidt camera images.
Here is an example....

I used HA data at 50/50 to the red followed
by HA as luminance at around 40%

The only problem I have is that the Tech Pan images
have bloated bright stars due to halation that I
don't have on the color images. I guess this is not
a problem with CCD.
