Description

The Squid Nebula is an extremely faint object thought to be around 2,300 light years away in the constellation of Cepheus and was discovered relatively recently (2011) by a French amateur astrophotographer named Nicolas Outters. It is catalogued as Outters 4, or Ou 4. It was initially thought that the Squid might be a planetary nebula, but this is no longer considered to be the case. The nature of the object is, at this time, unknown, although the ‘bipolar outflow’ is centred around the star cluster containing HR 8119 (Corradi et al, Astronomy and Astrophysics 570 - 2014).

The Squid is surrounded by the much brighter Flying Bat nebula (Sharpless 129) – a large emission nebula.

This is a 4 panel mosaic which was photographed between 21 August and 16 October 2020 using a rig in Spain that is privately owned and remotely operated by Barry Wilson and me. Back in 2017, I attempted the Squid using my widefield dual rig. I was able to accumulate a reasonable amount of OIII signal in 2017 and I decided to incorporate that into the new data.
