Some will say there's a lot of noise,others that Ganymede is all artifact and I'll say I was happy.
In the midst of clouds and extreme turbulence,I can't complain. The only thing I wanted is a good night of seeing!
Purist processing without making separate Ganymede. All together at once so as not to be too much trouble

28日に比較すると風が強めで、シーイングと透明度が少し低下していました。
撮影中も低下傾向で23時過ぎには木星像がユラユラと揺らいでいました。
木星面に大きな変化はなさそうです

良く晴れましたが、気流は今一歩でした。
北側の白斑が目立ちますね

南半球の白斑群がある経度です。ＢＡの前の白斑は、相変わらず縁が不明瞭です。
カラーでは、ＥＺが赤みが有って、ＳＥＢｎと離れているように見えますが、Ｒ画像ではＳＥＢｎとＥＺの模様がつながっているように見えます

一昨日と同じBAから後方の領域で特筆すべきことはありません。
シーイングは中程度で、細かいところはあまり見えませんでした

低気圧の縁を回る風が低層から10m/sを超えて強く、雲も流れて安定しない天気でした

最近の札幌はまともに撮影できる日がほとんどなく、
久々に晴れましたが、気流の状態は悪いです。

An extended session with conditions continuing to improve. The GRS was in transit.
Not sure if it is my processing,but the GRS appears quite pale in colour and the region nf is very turbulent.
The recent STB outbreak region was well placed. The best seeing conditions that I have had in quite a while.
There appears to be an extension off the leading edge of the GRS - almost like a reverse flake,
but no indication in CH4

Imaged Jupiter August 30th in reasonable seeing,the longer wavelengths provided the best of the data.
I note a prominent red oval on the edge of the NPR,many very small dark spots are resolved within the NPR particularly in the 685nm IR data.
Two thin red linear barge like features are resolved in the NNTeZ between the CM and P limb.
Three barges are seen in the NEB. Oval BA is well resolved as is WS6,A5,A4 along with DS7 (Clydes spot).

This was mainly a test under poor seeing of the Chroma Technology CH4 filter,
which looks to be as perfect of their UV (so-called "Bessel U") filter.
A comparison with my good old Idas CH4 filter shows an equal luminosity of the image...
but with a noticeable higher contrast. This is due to the "square" transmission of the Chroma filter,
while the IDAS presents lower transmission before,and after,the CH4 absorption band.
On such a narrow band,
the design of the transmission of a given filter is critical and will lead to noticeable differences on the performances.
