ngc 2841 - old data, new process

[wimvb]

I recently saw an image of flocculent galaxy ngc 2841 on astrobin, and remembered that I had imaged that galaxy four years earlier. At that time I used the ASI174MM-Cool as my main imaging camera. Large pixels can go deep, and the small sensor helps with framing. With much better processing tools at my disposal, I determined to create a new version. Especially NXT allowed me to go much, much deeper this time.

This time I was able to show the very weak halo that surrounds the galaxy. This is signal which my earlier process only hinted at.

Here's the old versioin, with capture details

This is the new version

Not just more outer signal: it has interesting structure.
