This will look better once the internet at large supports HDR color profiles

Amateur astrophotographer
Elephants Trunk and Flying Bat nebulae
Image 1 includes some Hydrogen Alpha data. Image 2 is more traditional LRGB.
For the curious, here is the exact same raw data without the AI based star correction and deconvolution. The algorithms are trained exclusively on Astronomy images to understand and correct ideal PSFs and not “invent” detail that isn’t present in the data itself. You can really see here in this comparison how much of a difference tight and controlled stars make in a good astro-photograph
My last post was an #astrophotography image where I framed the Heart and Soul #nebula together with the Double-Cluster. The purpose of that shot was primarily to collect new data to correct the star field for a poor imaging session I had previously where the #Comet C/2017 T2 PanSTARRS was passing through this frame. It was windy and very cold & I missed focus and had ugly stars.
Now thanks to modern #AI tools that can correct for these aberrations, this old data stands on its own all by itself.
Older dataset, but I’ve been playing around recently with new ways to combine broadband and narrowband data to make nice astro photos. The newer AI star removal tools that are available really make processing stars and diffuse structures independently a breeze!
Kinda weird framing, but I wanted to get both the Heart and Soul nebulae and the beautiful Double Cluster into one shot. RGB supplemented with narrowband data (Hα and OIII).
Probably one of my favorite #astrophotography shots I’ve done. I collected this data during the Almost Heaven Star Party in 2019. Clouds rolled in about half way through the night, and I didn’t get to take any Blue subs. I couldn’t finish from home because my own skies are so light polluted. So I had an idea - I had plenty of L, R and G subs: if I subtract R and G from the L (and compensate for exposure time), wouldn’t that result be pretty close to B?
I think so! Lagoon nebula in LRG and sB
And here is that same dataset in “Hubble Palette” - Sulfur data to R, Hydrogen data to G, and Oxygen data to B
