Sharpless 132

[Hughsie]

I started this project back in September 2021, capturing the H-alpha channel, but then bad weather (or should I say standard weather) kicked in. By the time the next clear night had come along I had decided to work on the Cave Nebula and so Sharpless 132 got parked.

Just over a year later a couple of clear nights at the start of this month popped up and so I decided to revisit Sharpless 132 and finish the project with Oiii and Sii. I always keep my imaging data, just the master lights and master calibration files, as well as the SGP profiles so I can match the original camera orientation should, like in this case, I want to revisit a target and add more date.

With 17 hours of integration time I managed to squeeze this image out of PixInsight.

Sharpless 132 is home to GP Cep, a Wolf-Rayet star which is lighting up this dim emission nebula. As the human eye like to pick out patterns, this region is also known as the Lion Nebula and originating from its ‘head’ is a blue Oiii stream of gas which is thought to be a ring of gas being blown out by the stellar wind coming off GP Cep.

 

 

All the best,

 

John

Thank you Simmo, much appreciated as it took a long time and several attempts to produce the colours I wanted.
