The Lower's Nebula (Lower's星雲)SH2-261
Since Redcat51 has been working hard, I decided to wake up C6+Hyperstar, who has been sleeping for 10 months, and ask him to do his best.
Playerone's Uranus-C IMX585, which I originally purchased for HSTC6. This is the first meeting with HST6.
I wanted to get used to it, so I took a picture of the Lower's Nebula.
It's like the blue doesn't come out. I thought it was going to be trashed, but I wanted to finish this nebula somehow, so I added another 2 hours of Signal on the second day. A little blue came out, but it's not perfect.
Is it incompatible with the 5nm Duo filter? , Is the IMX585 + HSTC6 incompatible (IMX585 and HST11 are fine)? Let's investigate the cause through future shooting.
However, I aimed at the troublesome Target when I woke up.
