This is a narrowband bi-colour image based on test data from a new obsy being commissioned in New Mexico.
Approx 4 hours of Ha and 9 hours of Oiii captured with a Tak FSQ-106ED and QSI683.
The result is heavily magenta, but you'd expect that when mixing Ha and Oiii
The Crescent Nebula, NGC 6888, is pretty obvious. It is a large gaseous shell created by the Wolf-Rayet star HD 192163. In the middle of the image towards the bottom is a much fainter planetary, PN G75.5+1.7, aka the Soap Bubble nebula.
