I am using CCD Stack. In Edit->Transform->Resize->SpecifyScale

Choose Mitchel as interpolation Method and tick preserve flux.

I only do this becuase my images with current camera are undersampled. Once my STF-8300 arrives with much smaller pixels I doubt I will have to do this.

Very interesting Chris.

What program are you using when doing this?

I haven't heard of the Mitchel algorithim before. Is this in the program or is it a plug in of some sort?
