It looks like Chuck has gotten a few of us to now to want and go after the Jellyfish Nebula. Way to inspire us Chuck! :)

Tuesday night was the first clear night in about 2 weeks here in SoCal after that huge rain storm that drenched the area. So I went out to Joshua Tree to get to some darker skies, it's about 2.5 hours from here.

I spent about 5 hours capturing this first, my priority was the Comet 2022 E3 ZTF, but it didn't rise until around 1am, so I filled that time in with capturing the Jellyfish nebula. This is my first time capturing it.

The image here is exactly as my OSC (Color) astro camera caught it. I didn't do any changes to the coloring to get it into the Hubble Palette, that is commonly used when shooting with a Mono camera.

This is also the first time that I have captured 10 minute subs with my astrogear. Usually I am in the 2 to 3 minute range, though I did do a 5 minute subs a few weeks ago. This one is fainter so I wanted the longer subs. The more I use my astro gear the more comfortable I am getting with the longer exposures. When shooting 10 minute subs, everything has to be perfect with the setup, the balancing the Polar Alignment, the guiding, all has to be right on the money. It felt good to be able to capture the 10 minute subs, and every one of them was sharp.

Nice shot Jim, I like the natural colors. The reason I do the Narrow band imaging is because I don't go to dark sites any more and I have too much light pollution.

Hey Chuck, thanks so much! I like how yours really pulls out that blue, the OIII I think?

Mono is the best way to get the best signals. And it seems like the best guys all use Mono. I think Mono is still the gold standard, so your way of doing it is tried and true. :) I just wanted an easy step up from my DSLR so I went with the OSC camera.

I appreciate that Mike. I think the colors have snuck up on me in this one. I am going to need to dial these back just a little bit I think.
