薄雲の切れ目からの撮影でした。

Seeing was good but resolution in violet is limited by the low altitude,though cloud structure is clearly visible.

最大離角なので、ちょうど半月状のはずですが、UVでは、もっと欠けた感じに見えます。カラーやＲ７０の画像では、ほぼ半月状でしょうか。

紫外撮影初挑戦です。吸収のためバーローもＡＤＣも使用断念せざるを得ませんでした。
目下のところＦ１０の直焦点が限界という感じです。せめてＦ２０は欲しいところですが。

Amateurs of astronomy usually use the special U-Venus filter to image the high atmosphere of Venus. But,it is possible to get best details using CaK-line filter and showing then the famous V drawn by the venusian clouds. Please,find this image taken yesterday 30 minutes before the sunset,from Bondoufle in France with my 100 mm refractor. It's a exceptional observation

Venus at Greatest Elongation on June 4,2023. Also took a visible image for the Schroter study.
[Gregory T.Shanos : Sarasota,Florida,USA]
We had good seeing here on the 4th June and I made another series of Venus drawings. Two dusky cloud bands could be made out:
Bright Limb Band: Visible and complete
Terminator: geometrically regular
Cusp Caps: Both very bright,the northern cusp cap may have been brighter.
Cusp Collars: Both seen- equal and more prominent than in the previous observation.
