That’s quite interesting. So 7.3e is clearly not insignificant at 60 seconds. Thanks for sharing that experience.
As for blending in the Ha, I am currently imaging NGC 55 without a filter (OSC) and plan to do an
Ha boost with the red channel of the L-Extreme. I’ve never tried this before, but looking at the quality of your image makes me think it’s well worth that extra effort.
Another great point about this image is how sharp the closer edge of the galaxy is in contrast to the other end. I’m not sure if this was done intentionally or not but it creates a powerful 3D effect!
