Well, this might be my last Saturn for this year. Imaged on the night of September 6, 2018 under good to excellent (according to CDS) seeing and average transparency. Two nights this week and two nights the previous week featured some of the best seeing I experienced all year. Conditions were a bit better tonight than last night. Scope collimation was the best I've had it all year with no tweaks needed from the previous night (although still not quite as good as it could be I'm sure).

Imaged with a C8 Evo, custom Siebert 2x barlow, ZWO ADC, Baader UV-IR Cut filter, and ZWO ASI224MC. Imaging train was configured to give me ~F/24 (slight adjustment from the previous night to give a slightly lower F/# which enabled me to attain better ADC settings). Image capture using Firecapture. Gain set at 325 and exposure was 30 ms to get a histogram at ~60%. Stacking in AutoStakkert3 (best 20% of ~10000 frames captured over ~300 seconds, 1.5x drizzled). Color balancing and Wavelet sharpening in Registax6. Derotated and combined three images in WinJUPOS.
