Leo Trio / Leo Triplet / M66 Group

L = 7h00m with AT6RC + TRF-2008, STT-8300M and Mach1GTO (oakland, ca)
RGB = 2h35m with FSQ-106ED, QSI 683wsg and Paramount ME (sierra remote observatories)

RGB was completely uncalibrated, so i'm sure i can do better on this. the L is slightly cropped for framing, since i messed that up.

L data from SRO exists for this project but i thought i'd start by merging data from my home setup plus our shared remote setup at SRO. the 1100mm FL of the AT6RC+reducer matches the target a little better than the tak, but clearly due to the dark sky at SRO a much better LRGB result can be had, albeit with a little less resolution (2app vs. 1app)
