Stacking - [OMG] What has happened here? ...... HELP!!!!

[swag72]

I have attached 2 images from the same data run as I have come to a end of my knowledge and I hope that someone can shed some light on this.

Imaging with an Atik 314L+ at 0 degrees using Baader LRGB filters.

The first image shows 4 combined and uncalibrated stack of the LRGB data (uncalibrated to ensure that the issue isn't calibration files) - I have corners missing on the green and luminance data. When I look at each individual sub, the corners are all there, but for some reason this is happening. I am stacking in Maxim, as I always do, using an SD combine and an automatic correlation alignment.

Can anyone suggest what is happening here?

The second image is a stretched (butchered!!) uncalibrated and stacked blue filter sub. As you can see, I have some kind of odd rectangle in the sub. Don't know if this is a related issue - the sizes are different.

Can anyone help with any of this? I just don't understand what is going on.

Just a quick thought Sara, could you try stacking the subs in DSS and see if the problem is replicated with that package?

Might help pinpoint the software or the subs perhaps?

Looks like it was an issue in Maxim picking the wrong alignment choice. My correlation standard didn't seem to work so well this time for some reason.

Catastrophe averted!!!

All's well that ends well
