Jupiter June 20
While waiting frostily for the early morning approach of Titan to Saturn I took some midnight captures of Jupiter. Seeing was not predicted to be very good but a few images came out okay with a bit of detail round the GRS. In case anyone desires more details of the capture than are on the image I have added the capture text file.
Have not yet looked at the Saturn captures but are not very optimistic on those as seeing appeared to deteriorate by 1am on the 21st and the fog came in around 2am and before Titan was close enough for a really good view.
Just to add a bit of variety, I have included an infra red image from the early evening of 19th June in which seeing was even less steady. The filter was a ProPlanet 742 IR filter. Ganymede was just departing Jupiter and so I was hoping to catch a view of it. I had hoped the result of the filter might be less seeing effected but as you can see it does not seem to be much benefit on a 6 inch scope for Jupiter. That might be because only around 5000 frames were captured over the same period 20,000 or so would normally be obtained. If I had bought an filter at around 640nm it just might have been a better fit for this scope.
