Description

Imaged Saturn and Mars on the night of July 10, 2018. The seeing was very good ~ 4/5. One of my better Mars images. The global dust storm is pretty much obscuring most surface features, but the south polar cap and northern polar hood are somewhat visible and some surface features are just glimpsed. Based on some reading on the cloudynights solar system imaging forum, I tried imaging with and without the IR-cut filter (some folks saw better detail through the dust storm without the IR filter). My results were similar with a slightly better result without the filter which I am posting here.

Imaged with a C8 Evo, custom Siebert 2x barlow, ZWO ADC, NO filter, and ZWO ASI224MC. Adjusted the imaging train to give me ~F/25 (by playing around with the adapter the custom barlow is connected to, using a slightly longer one here). Image capture using Firecapture. Stacking in AutoStakkert3. Deconvolved in Fitswork4. Color balancing and Wavelet sharpening in Registax6. Lastly, derotated and combined 3 frames in WinJupos10.9 to generate the final image. Each of the individual images is a stack of the best 25% of ~15,000 frames captured over 240 seconds.
