NGC7822 - Cederblad 214

NGC 7822 is a young star forming complex in the constellation of Cepheus The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 3000 light years distant, with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45000 K and a luminosity ~100000 times that of the Sun. The star is one of the primary sources illuminating the nebula and shaping the complex's famed pillar of creation -type formations.

In capturing the 2 pane mosaic of NGC7822, I found a small area of nebulosity. Checking the original subs I could see that it wasn't a processing artefact. Further investigation has shown this to be Abell 1 - a small and faint Planetary nebula.

​This coloured version is an interesting mix of data. The main detail has been taken from a 2 pane Ha mosaic with the ODK10. The colour used has been a 2 pane mosaic of SII data taken with a Takahashi FSQ85.

This is an earlier image I took of the same target, but with different equipment. You can see that there is a slightly different field of view with this combination and the target appears bigger in the frame.
