Hey Alex

Nice pics! I’m surprised you were able to capture as much as you have with the conditions. I had a quick peek at Jupiter earlier on and the image looked very soft and mushy; definitely one of those nights on which I would not even attempt any hi res imaging.

Generally, for Jupiter at your configuration, the limit is around 90 to 100 seconds before Jupiter’s very fast rotation becomes quite noticeable. Most certainly the wind hammering your ‘scope would induce detail-destroying vibrations and poor collimation would also contribute to a soft image.

Cheers

Dennis
