M57 The Ring Nebula Close-up with C-11_QHY5III462C

M57 The Ring Nebula in Lyra – An Extreme Close-up C-11 & QHY462C Camera.
I was originally Setup and ready to image Jupiter with a 2x Barlow, but was waiting for Jupiter to clear my Neighbors trees in the East,
so I decided to swing over to the ring nebula to try an extreme close-up with this QHY’s uncooled planetary camera just to kill time.
It actually turned out okay for being an uncooled Cmos planetary video camera..and even showed some nice details in the ring too.

The Ring Nebula is a dying star blowing off its outer atmosphere. Through most telescopes it appears rather small, 1 arc-min, but it is very bright, 8.8 mag., and with a little magnification you can visually see what looks like a smoke ring or a Cheerio floating in space.

Messier 57 or M57 is a planetary nebula in the northern constellation of Lyra. It is located at 2,283 light years from Earth.
The Planetary Nebula’s diameter is about 1 light year(5.8 trillion miles). Such a nebula is formed when a star, during the last
stages of its evolution before becoming a white dwarf, expels a vast luminous envelope of ionized gas into the surrounding interstellar space. The 15.2 Magnitude star at the center of the Nebula is the White Dwarf.

Captured, 63 x 10 sec. exp., Fire-Capture FITS files, 30 dark frames, no flats needed since the FOV is so narrow and evenly lit near center.10 minutes & 30 seconds total integration time, before the clouds rolled in.

Scope: C-11, F10, Mount: Bisque MYT, Camera: QHY5III462C, Binned 1×1, Gain: 330, 2x Barlow, (F20 FL: 5600mm) FOV: 3.5′ x 2.5′ Res: 0.12″ Captured from my backyard observatory in Dayton, Ohio USA on 07-27-2021 @ 03:11 U.T.
