ASTRO: NGC4631 pushed
This was taken from the same data as the color image. But when I pushed
it the colors went wild so converted it to black and white. Now instead of the whale galaxy I see the bottle nosed dolphin galaxy complete with tail flukes. Due to frost problems, mostly confined to the edges but spotty throughout the image, I had to cut off the very dim part of the data by subtracting a set amount from all pixels to get rid of the frost effects. I need to redo this when the temp is warmer so more of the faint tidal distortions can be seen. Still it shows a lot of distortion in both galaxies. 14" LX200R@f/10, L=8x5' binned 2x2, STL-11000M, Paramount ME Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

This is an amazing photo to me.

Thanks,
With a lot more exposure time I think that upper arm of the companion will arc over and back down to 4631 at the "bulb" part of the "porpoise's head". That was hinted at in the data but lost in the noise. I'd only exposed it for "normal" processing. Nothing but clouds since and now the moon is getting in the way but clouds are to continue for a while longer anyway.
