Shooting the video stars - Moon and Jupiter

The sky looked promising in the early evening. It's been a while since I shot any planetary video, but true to form when I headed out later, thin clouds were starting to form. I decided to trust my luck, before Tropical Storm Barry has a chance to throw more clouds my way. Seeing was average and transparency was poor. I forgot where Firewire hides white balance controls. In the end I'm glad that I persisted.

Europa on the left with Io and its shadow transiting Jupiter’s disk. Questar 1359/89mm, Darin 2x Barlow, and ZWO ASI1224MC video camera. Best 5% of 9449 images. Video captured in Firecapture, 1.5x drizzle stacking in AutoStakkert 3, deconvolution in Lynkeos, and final crop, exposure, and white balance in Photoshop. Taken on 2019-07-12 05:01 UT.

Plato and the northern highlands on the Moon. The craterlets visible on Plato's floor range from 2.4 km (1.5 miles) to 2.7 km (1.7 m). The smallest is 1.11 arc sec in size. The Rayleigh Criterion resolution for an 89 mm aperture is 1.53 arc sec so this is 25% better than the Rayleigh resolution! This my first time imaging the craterlets with this setup. I'm looking forward to what I can do with good seeing conditions. Questar 1350/89mm telescope with a 2x Dakin Barlow and ZWO ASI1224MC video camera. Captured in Firecapture, best 25% of 5779 images stacked in AutoStakkert 3, deconvolved in Lynkeos, with final crop and exposure adjustments in Photoshop. Taken 2019-07-12 05:11 UT from Austin, Texas.
