Preprossing error
Hi, An error occurs with the 4'th image, when I am trying to stack. What can I try to let AA7 succeed? Any parameters that I can tweak?

Re: creating Hubble palette
I tried both the above methods, but I wasn't pleased with the result. Then I "stumbled" over a thread on stargazers lounge, can't re-find it, unfortunately, where someone mentioned, that in the case of H-alpha and O-III, one needs to create a "synthetic" green channel, by multiplying H-alpha with O-...

Re: creating Hubble palette
I found this Youtube video:

The trick is to use the Ha and OIII images as follows in Trichomy:
Red: Ha
Green: OIII
Blue: Ha

Scripting functions for stacking?
I have a set of over 500 fits, that I need to stack in groups of 10's.
stack1 = stack(i1, i2, ...i10)
stack2 = stack(i11, i12, ...i20)
.
.
.
Doing this manually, quickly becomes boring.
Is it possible to automate this in AA7? I san not find any suitable scripting functions.

How to specify FIT format?
The AA7 help says: If just one pixel has a value outside the range 0 to 65535 ADU or it is expressed as a floating point value, Astroart will save the file as a 32 bit FITS (integer or floating point). How do I switch between making AA7 save as 32-bit float and 32-bit integer? One of the sub systems...

Re: Connection to aladin website fails on AA7 SP1
Works fine on my setup; AA7 SP1.
Just right-clicked the Atlas, selected "Aladin web site" and got to this page:
