Hi all
This set of images is from the last session of good seeing and clear skies back on the 14th May local time. It's been horrible seeing and/or cloudy since then. Glad to have finally made my way through the backlog of processing.
This set of images covers 80 minutes of rotation and includes the GRS/LRS/3rd red spot, plus Callisto's shadow. Seeing was very good but transparency got worse as the session went along, thanks to mirrors dewing up. The last half of the avi's were captured at 15fps as a result.
I've got some avi's of 3 of the 4 jovian moons in the same FOV, and they'll be attached to a Jupiter image along with an animation in the next day or two.
I've been chatting with David Pretorius regarding my processing of Jupiter images from this year compared to last, and some comments from Gianluigi from the WinJUPOS team have made me re-evaluate the gamma curves reduction I was doing. On this new laptop i'm using, all images are very bright so a curves reduction makes sense and looks good. However after the feedback and discussions it appears that the images are too contrasty and lacking limb detail on most other monitors. So with this set of images, they appear much lighter to me - hopefully they'll be more pleasing for everyone else as well.
12" newt, DMK21AU04. 30fps for the first image (in poorer seeing), 15fps for the last two images (in very good seeing).
Thanks for looking.
