This is a beautiful image. I think the composition is fantastic. There is whimsical dreamy quality. Imaging Luddite so cannot comment on the technicals
I use the 3" 0.8 reducer from my TS115 on the 72, reducing it to f/4.8 and 340mm which is fairly wide, but I'd like to go wider and get more differentiation from the 115's FOV.
The image above is the full APSc chip with no cropping.
The Redcat 51 looks interesting but too expensive once you nudge over $1000 and add the import fees.
Thanks Chris, it's the most naturally colourful region that I can think of. A touch wider field would be nice, especially to capture the more intense reds above Sigma Scorpii.
