When I used 'bilinear' in the Align tab instead of 'bicubic resample' for all stacking from Deinterlace of an image … the final four M82 images seemed to look a little smoother in the 'background' around M82 . Canon 6D 667secISO4000 OrionSkyGlow 2in. filter 4800mmFL ...Deinterlace each CR2. image at Bin1 and 'Auto-Correlation bilinear Sum' then all four 12bit 0-4095 processed CR2.s 'bilinear Manual 2 star - SigmaClip SigmaFactor 0.5 Linear Normalization:50% . This JPG is the result but I brightened M82 and Un-SharpMask and Dilation and Saturation and there wasn't ever any 'background' smoothing to any of the images used ... the FITS is un-processed and seems to look smooth in the 'background' so I think all 'bilinear' and Linear options have a smoother image than the 'Bicubic resample' image of M82 .
