I don't manage to get as much sky time as I'd like, so this image is my first time messing with narrowband, and my second time out shooting stuff. I aimed to get some data to play with through all of my filters, but I messed up the sequencing and my LRGB ended up being LRRR
But the NB worked out fine, I think. Many improvements to be made.
I don't really know what I'm doing, but, holy heck, I think I'm falling in love with narrowband!
I was figuring out how to do stuff for a lot of the night, but I managed to capture the following image in the wee small hours.
It's not perfect. There's something about the stars I'm not happy with, but this is kind of the limits of my abilities at the moment. I'd welcome any suggestions as to where I can go from here. Also, any suggestions as to what I can do with the Lum and Red channel data I collected while I'm waiting for another opportunity to get out there.
