Description

A challenging target:
  • very small
  • very high dynamic range (core vs. outer shell)
  • very seeing dependent

I shot <3h for RGB with the intention to get all my structure from my luminance data. I shot my RGB frames the night before L and seeing was dramatically better when shooting RGB.
So much so that I decided against using L altogether. This not a problem since the core is so high SNR with RGB filters anyway.

Two nights and the majority of integration time I dedicated to Hα to reveal the outer shell of the Ring.
I'm still suprised how much light the Esprit 120 gathers at f/7.
