Description

Imaged Jupiter on the night of June 3/4, 2019. Main objectives of this observing session were to collimate the scope and watch Io exiting from Jupiter's shadow (GRS was not visible from my location this evening). Seeing was generally poor during Io's exit from Jupiter's shadow.

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/20. Image capture using Firecapture with gain set at 300 and exposure at 8 ms. Stacking in AutoStakkert3 (best 25% of ~20,000 frames captured over 180 seconds.). Color balancing and Wavelet sharpening in Registax6. De-rotated and somewhat poorly aligned images using WinJUPOS. Animated GIF created using Gifmaker.me online tool combining 4 frames (1 before shadow exit and 3 after, each taken about 5 minutes apart).
