Hi all -

This image from last weekend - captured during good seeing but poor transparency. Jupiter has inched up to 32 degrees as it passes the meridian - hooray!

Taken with my 10" mak at f30 and DMK21BF04 b&w webcam with RGB filterwheel. Luminance is made from 250 frames each in red and green.

best wishes -
Alan

Hi Alan,

with the planet at only 32 degrees this is an astonishing result! But I had no doubt when I clicked on your post that I was going to see something of value grin regardless of the low altitude.

Ciao Alan

PS here we had a time regression! It is snowing even at low altitude and we returned to winter temperatures after a week of 30+ degrees Celsius! Amazing weather :C

Thanks for your comments!

Robert - I usually capture streams in IR, R, G and B - the total time can run between 4-5 minutes with filter changes with 66ms exposure. I prepare the luminance from R and G streams for several reasons but the rotation seen over this long a time period is a big one. A bigger aperture and faster fps rate would be a big advantage here.

Beautiful image! Wonder what that outfit
could do with 90 degree elevation....

Wow Alan thats a superb result! We're whining now about Jupiters low altitude, but doesnt it get even worse in the next couple years?
Time to go south I say wink

Another view showing R and IR components to RGB. Interesting to compare to Jim Phillip's images from June 1 - the bright disturbance just north of the GRS on the following side seems to have broken through the northern edge of the SEB during the past week.
