Finally no upcomming clouds in this session,one with exellent circumstances of seeing with a slight hazy sky.
I was able to do a very rare observation, namely, a moderate bright star came so close to Uranus that it was
captured together with the Uranian disk in one HR-(secundairy focus)image.Usually images of stars in a field with
Uranus are taken,in primary focus.The nice round speck of the airy-disk represent the good seeing I think.(especially
for 30 degr. altitude).This image is taken through the red610 filter.
The animation is interesting,as it shows the movement of the Uranus disk from the star in exactly 2 hours and 25 minutes.
For someone who started with planetary photographie on classic film, as I did also, capturing this kind of things was
fully impossible in that time.
Best regards,
