Comet C/2017 K2 PANSTARRS (彗星 C/2017 K2) C/2017 K2

Last shot of this season

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.
