Description

Surprisingly it stayed clear all night last night so I got almost 14 hours from my dual Esprit rig on this enigmatic planetary nebula. There was a full moon of course but I still took the chance of collecting some RGB with the Esprit 100 and ASI071. I only expected that I at best could use it for star colour but the data turned out to be virtually without gradients. It probably helped that the scope was pointing away from the moon. I also decided to go for rather short subs so I ended up waiting for my computer to stack 263 x 90s of RGB data. On the Esprit 150 the ASI 1600MM was collecting 2 hours of Ha (Baader 3.5 nm) and 5 hours of Oiii, (Baader 8.5 nm) yielding another 200 or so subs. I also shot some 10s and 30s subs to save the very bright core of this nebula - the actual eye.
