WR134, NGC6883 and Sh2-101 in HOO

Wide field image in constellation Cygnus.

WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus,
surrounded by a faint bubble nebula (the blue circular nebula up left from the center of the image) blown by the intense radiation and fast wind from the star.
It is five times the radius of the sun, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun.

W63 (Westerhout 63) supernova remnant, (SNR G 082.2+05.3)

Westerhout 63

W63 (SNR G082.2+05.3) er en svak supernovarest i stjernebildet Svanen som lyser for det meste i Oiii.
Vi ser den i bildet som en blå eggformet ring. Den befinner seg ca 5000 lysår vekke og har en utstrekning på ca 150 lysår.
Forøvrig er det som mange steder ellers i dette stjernebilde mye H-alfa signal.
Helt i høyre bildekant rett ut for de to sterkeste stjernene kan vi skimte StDr 139 (Skarpen Nebula). Den ble oppdaget i 2021 i et bilde tatt av Ola Skarpen.
