California Nebula. SH2-220.
Fourth time imaging the California Nebula. Really an easy target from my location. It’s a dense, bright nebula and rises within my limited line of site. I need to cut down more trees!
This time I used the Optolong L-eXtreme Dual-band filter. Been using that primarily this year. But I have to say my detail from 2021.11.23 is pretty nice. I used the Radian Triad filter then and captured at 300s exposure time. Probably the usage of both helped capture that extra detail then. I still like the results of my latest but I will probably next time use the Radian Triad.
Below is something new I will try keep up with. I’ve been live streaming on Twitch of me processing my images. As for YouTube, I plan on taking the recording from the feed and post a sped up version. Below is the result. Hope you enjoy!
