Cave Nebula in HaOIIILRGB

Shot with my Canon 300mm f/2.8 (stopped down to f/4), ASI1600MM-C riding on a IEQ45 Pro. 27 hours of integration. This is one of the fainter targets I've imaged. It took way more exposure time than I had anticipated to get a decent OIII signal. At any rate, I'm pleased with the final image. I may revisit this target next year under dark skies and add more luminance data to it.

Congrats that came out great, and a lot of effort as well.

Thanks, Robert

Good job, looks like there's a bit of noise reduction artifacting in the top left and especially around the smaller stars in general. Hard to tell at low res though. High signal areas look great.

that an awesome shot I'm always amazed what a little camera can pick up nice job

The photo is absolutely amazing, thanks for sharing!
