Previously, I captured 5hrs of Ha, SII, OIII data on the wizard nebula. I had an autoguiding error in the middle of the night and did not capture the planned Oiii data. We had a clear evening to capture more data. Rather than simply finish the plan on Oiii at gain 139 using 180 second exposures, I ran a test of several different gain and exposure durations.
I will post my camera settings comparison separately, but for now, I combined all the Oiii data here to complete the Wizard Nebula in the SHO pallet.
