Description

I have so much to learn in processing. Once I think I have something down, another problem comes up. Isn't that the best though, when you are constantly challenged?

I recently acquired a Fra500 to serve a few purposes: 
1. Go wider as my only scope before this was an Edge 11 and not make every large nebula a mosiac
2. Have a more portable setup for dark sites
3. Using above to be a bit easier than constantly guiding 2000mm

First light is this photo, though I did take a quick break to point it at Rosette and capture a measly 72 minutes on it (though it is quite an impressive result for such short time)

Anyhow, I think I gathered enough for now, though I certainly want to try and reprocess this, or gather more data. I shoot in B5 skies, so while not impossible to get IFN, it was a challenge. I used many reference pictures to make sure I wasn't inventing data, so I think I did ok, but we can always use more integration time. The issue I had was trying to keep the galaxies nice while highlighting the IFN. I think with more practice (and data) I can do even better:

L 128x2180s Gain 100
R 62x180s Gain 100
G 62x180s Gain 100
B 59x 180s Gain 100
Ha 37x300s Gain 100
