Jupiter with Io in transit - 2 Oct 2022


Recommended Posts

I had my 2nd session with my new ASI462 camera on the C14 last night. The seeing was better than last week, but still very in/out, with focus changing minute by minute, making it difficult to determine best focus. Io and it's shadow were in transit, so I opted for a series of 2 minute SER videos, which I de-rotated in WinJupos before grading in AS3!, with further derotation and stacking of the TIFFs in WinJupos. Sharpening was done using wavelets in Registax6.

The stacked image had a large blur where Io and it's shadow were in transit, so I pasted them back into the stacked and sharpened image from a single SER that represented the correct timestamp of the de-rotated image. Final colour saturation and levels adjustments were applied in Affinity Photo.

Io itself is somewhat lost due to poor contrast aginst Jupiter's bright cloud surface.

 

Thanks for looking, comments and feedback welcome.
