Description
This was a collaboration with Tom Carrico at ARGO. Tom took 5 hours of H-a with a 180 mm telephote lens on a ST2000XM camera with a 6 nm Astrodon H-a filter. I took the SII and OIII images with Astrodon filters in an STL11000XM and Takahashi FSQ106N refractor. The plate scales are about the same. OIII = Blue. H-a = Green. SII = Red.
