City lights Pleiades with the RedCat

When the clouds are away, Galileo's children will play. This is my first try at the Pleiades with the WO RedCat 250/51mm telescope, I haven't had luck capturing the nebulosity in the Pleiades with small equipment under Austin's light dome, this is my first success. I'm looking forward trying this under a dark sky. The blue cast is from the Austin Bortle 6 light dome and a sky glow filter.

William Optics RedCat petzval APO refractor on a Vixen Polarie mount, and the full frame Sony a7 iii. 118 minutes total exposure in 30 second frames at an ISO of only 640. Stacked in Nebulosity with exposure stretch and final crop in Photoshop.

!00% crops from a single frame

The following !00% scale crops from a sample 6000x4000 pixel full frame image are unprocessed other than the conversion from RAW to JPEG formatting, exposure boost, and cropping:
