90 Minutes of Jupiter's Rotation (and Great Red Spot)

This shows 90 minutes of Jupiter's rotation on January 21, 2025. To create this, I captured a sequence of over forty 90-second videos over a 90 minute period with an 8" telescope, at an estimated 4400mm focal length. I processed each video to create a starting frame, used wavelet sharpening, and then combined them via "derotation" into a joint model, which could then generate an interpolated (and clearer) image of Jupiter at 1 minute intervals for final sharpening and color balancing to bring out the gas bands and Great Red Spot.
