Helix HOO RGB

An interesting comparison is the Helix with an hour each of Ha and Oiii with
35 min of RGB added and Helix HOO HOO . Very close to the half moon.

A lot more of the fine inner structure with HOO only and a lot more of the red nebulosity with added RGB. More Ha Oiii would be good when the moon buggers off. The galaxies were a complete disaster in HO under the moon.

A great change to get closer at 1000mm and little faster at f5 for these small objects.
