Sorry for bad english - i'm from Russia... :-)
About problem: then i probe to allign 3 *.fits images with moon, i get error:
"Image moon1 is not 2 dimension"
But imcomb of this 3 images are working fine!
IRAF version is 2.13b
System: Gentoo LinuxOne more - this 3 images i have in the list: @list_moon
I created moon1.coords and insert into this file:
1272 1347
As i know, in this file must be placed coords of pixel wich be centerd ither images?
In the file shifts.txt i inserted shifts in the pixels for each images:
0 0
97 42
27 113Where i do wrong? Help me please!PS. IRAF - is a power! But i bad know this software...

But imcomb of this 3 images are working fine![/quote:75a1bc12ab]IMCOMBINE is able to work on non-2D images, however IMARITH cannot. You probably have either a 1-D or 3-D image (i.e. an image 100x100x1 is considered 3-D]. You can use the IMHEADER task to check the image, e.g.[code:1:75a1bc12ab]cl> imhead moon1.fits long+[/code:1:75a1bc12ab]If it's a 3-D image then something like[code:1:75a1bc12ab]cl> imarith moon1[*,*,1] + moon[*,*,1] newmoon[/code:1:75a1bc12ab]will use the image section [*,*,1] to extract the 2-D band from the image, or else do the same but IMCOPY the section to a new image.

Sorry... I posted mistake information!!! Here is what about i talked:

Here is my last result:
[code:1:28e66a4eea]
cl> imcomb @list_moon moons2323 offsets=moon.shift
Warning: IMCOMBINE: Error in offset list
Warning: Can't set output geometry
[/code:1:28e66a4eea]
moon.shift contain next:
[code:1:28e66a4eea]
0 0
49 63
1 113
[/code:1:28e66a4eea]Thirst lin contain 0 0 because it is shift of normal image. All other - containt shift by X and Y...
So, what i do wrong again?
I need result like after Registax working...
HELP ME!!! EPLAIN ME, PLZ!!!
This is my 3-d night in the IRAF... But no results!
