Objects: NGC 7000 (North America nebula), IC 5070 (Pelican Nebula)
Type: Emission nebulae
Constellation: Cygnus
Distance: 1,500 light years
Equipment: Atik 460/EFW 2, Samyang 135mm lens@ F2, Vixen GPDX mount, guiding with Lodestar X2/PHD
Date: July 15th. 2021
Subframes: 12 x 300s for Ha, SII and OIII each, no flats, no darks (hot pixel removal in Astroart).
Information about this object can be found in a previous blog entry here. Since I took that earlier image, the camera to lens spacing has been sorted out and the narrowband filters upgraded to reduce halos around stars. This has allowed me to acquire better quality data to support a colour image.
The above RGB image is from Ha/SII/OIII narrowband data (R=80:20 Ha/SII, G=70:30 SII/Ha, OIII=80/20 OIII/SII).
