Re: [APML] Astronomical Image Enhancement Trial

["Bert Katzung" <katzung1@attbi.com>]

Hi Dave:
Subtle but very significant improvements! The detail in M8 and the star
definition are both considerably better. I don't know how much more
improvement you can produce, but it looks mighty good right now. Have you
tried any CCD images? I have tons of poor ones that could use considerable
improvement! Let me know if you would like some and what image size is best
for your modem speed. Or I can send a CD with lots on it.
PS: How's that Mojave observatory coming?
