Here was another quick grab with the DSO setup once the moon came up on the morning of 17-MAR-2017. The seeing was quite excellent and allowed me to 3x drizzle stack the data. Considering I shot this video at f/7 on an 8" SCT, I was able to capture the long string of moons but still dig out quite a bit of detail on Jupiter itself. At the original capture resolution, Jupiter was less than 80 pixels across and each moon was just 2-3 pixels! This image is the best 600/2000 frames in RGB. The data was drizzle stacked then derotated in WinJupos. It ended up being a slight composite because I had to realign each moon's RGB data due to the movement in between captures.

Yes, its odd to see SGP as software used for planetary capture. But... I did this whole capture from the comfort of my office. I used SGP to plate solve and center the planet, then Firecapture to do the dirty work. The benefits of a large chip for planetary work keep stacking up. I don't know how I could go back to something with less real estate.

The moons, from left to right are Castillo, Ganymede, Io, and Europa. Ganymede's shadow is positioned just along the limb and the Great Red Spot is on the opposite limb just rotating out of view.
