I think that finally everything is now ok with my SHG :
Ha
Cak
and first shot in He...
...and in Hb!
For the treatment, I found a really easy way to remove the lines : GIMP. I found an option to remove the trail. It works pretty fine here too (except in Hb...)!

Re: SHG shots : Ha, Cak & He
Why are the bands are not purely vertical or horizontal? I need to rotate the image 91.X degrees rather than 90 degrees.

Re: SHG shots : Ha, Cak & He
The tilt is not from the merging program, but from the orientation of the slit.
You may tilt vertical direction rather than horizontal direction, which can leave a chance to remove the bands by others

Re: SHG shots : Ha, Cak & He
previously I was using vertical orientation with same issue...
I don't say that the problem is coming from your (great) soft but most probably it's a common issue with SHG 'cuase is not the first time I saw similar issue on other website....
In fact it's maybe (even most probably) because my mount is not perfectly align on the north...Don't you think?

Re: SHG shots : Ha, Cak & He
As I said in my last reply, the tilt problem should be from the orientation of the slit. The slit has to be perfectly aligned to Earth North-South direction, or else it will introduce some tilt.
