Description

My process of the interacting galaxies including NGC 4308 using HST legacy data with raw subs. RGB combined using stacks from the following WFC3 filters:  814 nm (mapped to Red), 550 nm (mapped to Green) and 435 nm (mapped to Blue) filters, respectively. Data at 656 nm was added as luminosity in the red channel to show the Ha signal of the nebulous regions in the galaxies. This HLA data was reasonably well calibrated, much fewer hot pixels than usual.
