Loosing red signal processing in IRIS-any suggestions?

[seeker372011 (Narayan)]

this is really weird. I am currently experiencing a problem I have not encountered before, and wonder if any one else has encountered or if there is something wrong with what I may be doing.

I have three 10 minutes subs and the individual RAW images when opened in photoshop shows plenty(well, reasonable) red signal

when I pre-processed, registered and stacked the frames in IRIS and took it to photoshop, I found I had less (!) red than in the individual subs. More overall detail as you would expect, much less red

I tried kappa sigma stacking with same result

I then took an individual frame-did not subtract a dark frame or divide with a flat field-converted to a CFA file in IRIS and then exported it to photoshop-and sure enough I had lost red signal.!??

can any one suggest what I may be doing wrong?

BTW is anyone aware of an IRIS yahoo group or something similar?

thanks in advance for any suggestions

Oh guru, sorry I can't help you but there is a yahoo group. http://groups.yahoo.com/group/Iris_software/ Your guru Jim Solomon frequents the place and Terry Lovejoy as well.
