Notes: This was an imaging run that took three nights to complete with 6 hours per filter and 30 minute subs for a total of 18 hours imaging. I've never imaged that long on one object before but I think the effort was worth it. I used the Hubble Palatte with SII as Red, Ha as Green and OIII as blue.

Thanks Astrogalaxy.

I think the 18 hours of imaging paid off. I'm hooked on multiple night imaging now so I'll be out there a lot.

Hi Rick,

Multiple night imaging?
Does it mean going on different nights but taking the same object, then stack up the photos?

That's exactly what it means and the more images you take the better the overall result.
