Y Cyg nebula and lots more in a small part of the Sadr region

The Sadr Region is a diffuse emission nebula region surrounding Sadr (Gamma Cygni) located in the center of Cygnus’s cross. Sadr can’t be seen in this image but it’s very close out of the frame.

Pointing a telescope towards the Cygnus constellation will always reveal some beautiful things. I decided to shoot this part of the region because of all the interesting bright and dark nebulae.

The HaRGB result that I recently shot with the ASI294MC didn’t give me any pleasure, reason why I went back to it as soon as I replaced the ASI294MC with the QHY294M Pro and Baader filters.

To shoot this part of the sky, I used the following equipment:

Sky-Watcher Eq3 Pro mount
Sky-Watcher EQ6-R
F6.5 TS65 Quadruplet imaging telescope
QHY294M Pro
2″ Antlia Astronomy Filter 3nm Ha
Baader 36mm SHO filter set
Qhy5 LII-M guide camera
9×50 finder-guider

Software used:
Eqmod, SGP, Stellarium with StellariumScope, PHD2, SharpCap for polar alignment

Location: Back garden, Bushey, UK (Bortle 7)

Date: 30.05.2021 to 18.09.2021

ASI294MC Pro:
24x600sec Antlia 3nm Ha Gain 200 Offset 10
