After a truly miserable 2 weeks of weather and jetstream we had a lovely calm,clear sky this morning. Seeing was the best for me so far this 'season'.

It was mostly cloudy today and condition was unstable.
Here's an interesting image,Io is over the GRS!! The SEB is dark.

なかなか風が収まらず、また流れる雲にも煩わされましたが、
明日から天気が崩れるとの予報だったので、めげずに撮ってみました。
1番目の画像には、大赤斑にちょうど重なっているイオが写っています。

この日はＧＲＳの正面をイオが通過しました。
薄雲に遮られながらも何とか捉えることが出来ました。
上階の庇による口径蝕を避けるためあえて小口径で狙いました。

Christophe Pellier (250mm Cassegrain)
Sorry for my long imaging silence these past months but I was without telescope. My usual 10" cassegrain always had weird optical problems on the secondary mirror that prevented it to perform as it should (wide turn-down edge,strong surface defects...). Last spring with a friend of mine who is highly skillful in telescope making,we decided to try a last chance "repairing",by modifying the optical design of the OTA from cassegrain to gregory.
The telescope of Gregory is an old,almost forgotten design (historically discovered even before the newton) that uses a parabolic primary (like the cassegrain),with an elliptic concave secondary,located after the focus plane,to the contrary of the cassegrain that uses an hyperbolic convex secondary located before prime focus.
As a result,the tube is longer than a cassegrain,but in return,the secondary is much more easier to figure... this was the main interest of the modification !
Now some 6 months later I'm happy to tell you that I own a successful 250 mm gregorian telescope. Each aberration visible with the cassegrain has been corrected (except the residual sphericity of course),and the star test is just very good,finally. You can see a photo of the instrument here (the added part is well visible ; the tube is now 110 cm long instead of 80 before) :

巻雲など、高層の雲を通してでしたが、シーイングは良かったです。残暑最後の置きみやげでしょうか。

Fair to good seeing and excellent transparency. Lots of interesting details across the northern hemisphere including some FFRs in the far north. Oval BA is weakly coloured. In methane the strange aspect to the SEB compared to its visible light appearance continues..

南から流れてきたせいで、ぶれた画像が多くなり残念です。

衛星のイオの本体と影の移動がわかります。イオ本体は南北が暗い。
