Last shot of this season

今シーズンのLastショット

It was the first comet photograph in my life that I managed to take 17 minutes for the first time in 22 days since June 4th.

I aimed for an exposure time of 1 hour or more, but spent 3 hours, and there were 11 decent frames for each of RGB.

In the ASTROBIN and FB astronomical groups, there are photos that show the tail with HYPERSTAR for a few minutes exposure time and F / 6.0 with an exposure of 1 hour or more, but as expected it is 17 minutes exposure with F / 8. Then it was impossible.

Now that we're in the perfect rainy season and thunder and squalls are starting to get busy every day, Seeds think this is the last shot.

(But if it happens to be sunny, I want to temporarily assemble HYPERSTAR and take a picture of the tail)

See you next season, starting around the end of October.

Thank you very much.

６月４日以来粘りに粘って２２日ぶりにやっとなんとか17分だけ撮影できたのが生まれて初めてのほうき星の写真だった。

１時間以上の露出時間を目指したが３時間費やして、まともなフレームはRGBそれぞれ11枚だった。

ASTROBINやFBの天文グループではHYPERSTARで数分の露出時間や、F/6.0で１時間以上の露出をかけてるものは尾が写っている写真もあるが、さすがにF/8で17分の露出では無理だった。

もう完璧な雨季に突入してしまい、連日雷とスコールが賑やかになり始めたので、今シーズはこれが最後のショットになると思う。

（でも偶然晴れればテンポラリーでHYPERSTARを組み立てて尾っぽも撮りたいな）

次は１０月の終わりころから始まる来シーズンにお会いしましょう。
