The Snowglobe Nebula (スノードーム星雲)  NGC6781

Test shot of C11 prime focus 280mm,F/10,f/2800mm.

I was planning to buy RASA11 last year, but I got C11+Hyperstar last year because I had to wait for a year in Thailand.
Therefore, the secondary mirror of C11 was never exposed to light during the past year.
During this period of the rainy season, even if you can see the stars, they are usually covered with clouds within 30 minutes to an hour.
Therefore, I think the Faster Telescope, which can handle even 30 minutes, is the best weapon at this time.
However, the planetary nebulae are scattered around this time of year, and I still want to shoot with a long focus, but I don't have the physical strength to replace it with the RC10.
So I tried C11's Prime Focus, which can be used just by changing the balance.
I wanted to shoot for 2 hours, but the clouds came out in 1 hour as planned.
More than 50% from the center has COMA, but it has nothing to do with taking planetary nebulae.

よって、30分でもなんとかなるFaster Telescopeがこの時期は最高の武器と思っている。
とういうことで、バランスだけ変えれば使えるC11のPrime Focusを試してみた。
