10-16 Jupiter at21_55_24_AS_F2500_ap1080 R6-2

Jupiter's moon Io and its shadow were going to transit Jupiter on October 16th, 2022 night. The GRS (Great Red Spot) was also supposed to be close to the center of the image. We took this opportunity to capture several videos of Jupiter to get this unique image. The dark spot in the middle is Io's shadow, lagging behind the small moon itself (brighter blob to the right of shadow). At the time of this video, Io was supposed to be on the top left edge of GRS.

 

We captured this image on October 16, 2022 using our newly acquired ZWO-ASI 178MC color camera. Our gear included the Celestron HD800 (C8 Edge) telescope fitted with a 2xPowermate. The effective focal length was a 4064mm which allows us to focus on tiny objects (like planets in our skies). This allowed us to take a nice close-up of Jupiter.

 

We used the "Lucky Imaging" technique for our image. In Lucky Imaging of planets, a short video with high frame rates is used to "freeze" the individual images to minimize the blurring caused by turbulence in the air column above us. We captured a video of 5000 frames using SharpCap capture software.

 

The video mode used an exposure of 20 ms (milliseconds), a gain of 265 and at 52 fps shooting speed. We then stacked the best 2500 of the best frames in AutoStakkert3 and then did wavelet sharpening in Registax to get the final image. Enjoy!
