After midnight skies were clear and steady in Austin making a great opportunity for 2020 portraits of Jupiter and Saturn. I used the 3 1/2" Questar 1350/89 mm telescope with, 2x Dakin Barlow, ZWO Atmospheric Dispersion Corrector, and ZWO ASI224 planetary video camera.
Jupiter's opposition was just five days ago on July 19. This image was taken 620 million km away with the light from Jupiter taking 35 minutes to arrive at my telescope. Io is the moon to the left. Europa and its shadow are transiting Jupiter's northern hemisphere in this image taken on 2020-07-24 5:45 UT. The best 10% of 2751 frames were stacked in AutoStakkert! 3 with a 1.5x drizzle, deconvolved in Lynkeos, cleaned up in Topaz DeNoise, with final crop and exposure in Photoshop.
Saturn's opposition is just over a week away on August 2. Last night found it 1.35 billion km away. The photons I captured took an hour and fifteen minutes to arrive from Saturn. The best 10% of 3627 frames were stacked in AutoStakkert! 3 with a 1.5x drizzle, deconvolved in Lynkeos, cleaned up in Topaz DeNoise, with final crop and exposure in Photoshop.
Here is my setup taking data last night by my mailbox with Questar, ZWO video camera, and MacBook. It was such a pleasant night that I stacked the Saturn data right there by the mailbox. One car passed by. If not an astrophotographer, they are probably still trying to figure out what I was doing.
