geoflewis Posted October 3, 2022 Share Posted October 3, 2022 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. 1 Quote Link to comment Share on other sites More sharing options...
geoflewis Posted October 5, 2022 Author Share Posted October 5, 2022 I processed some earlier data from this session, which shows Io just making contact with Jupiter at the start of its transit. Here is an annotated presentation of both images. Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted October 6, 2022 Share Posted October 6, 2022 Great images Geof. Jupiter really does turn quickly as you can see the features having moved such a long way in a relatively short time. Quote Link to comment Share on other sites More sharing options...
