The evening of June 13th was very hazy,with high cirrus clouds.
But the wind direction was very favourable and the seeing was quite
good,better than usual. I took some UV recordings of Venus,which
belong to the best I have made sofar. Unfortunately,the cirrus reduced
contrast of the clouds. I postprocessed the UV images in PS and these
are the results. A colour combination was made using a visual filter for
red and green channels. The UV was used as a blue channel. I was unable
to record a NIR image because of the cirrus clouds.
months,when seeing conditions in the morning are usually far better.
