Popular Post AstronomyUkraine Posted September 10, 2021 Popular Post Share Posted September 10, 2021 This is an SHO combination of the very faint planetary nebula called SH2-188. It also goes by the name of the Shrimp Nebula, the Firefox Nebula or the Dolphin Nebula. It lies in the constellation of Cassiopeia around 700 light years away. This was a tricky object to process, first it's quite small in my setup, and is located in quite a dense star field. The object is almost circular with a shell like structure extending beyond the main nebula, it is just visible in the image. The image has been quite heavily cropped to show the structure in the nebula more clearly. Integration time.10 hours on each NB filter. Processed in PI, with final crop in Photoshop. 10 Quote Link to comment Share on other sites More sharing options...

It's one nebula that does resemble it's name. I can also see why it has been called the Firefox nebula, although I suspect that is a recent name given to it.

TerryMcK Posted September 10, 2021 Share Posted September 10, 2021 Yes definite shrimp like in shape. 1 Quote Link to comment Share on other sites More sharing options...
Astrobdlbug Posted September 10, 2021 Share Posted September 10, 2021 A very delicate looking object and 30hrs of integration time - thats a lot of hours... On the processing I like that you have left it green and the red diffuse nebula in the outer shell. Nicely processed What does it actually look like in context of the full FOV you captured ?

Padraic M Posted September 10, 2021 Share Posted September 10, 2021 Very nice indeed! Stellarium has it as 10' x 3' so very small. I'd love to get a crack at it. Quote Link to comment Share on other sites More sharing options...

Bryan Thanks Bryan. I did a dynamic combination on this one after stretching the SHO stacks, instead of stretching after combining. The result was more red than a normal SHO combination. This is the full FOV, save for cropping some rubbish on the edges. My FOV is 74.17 x 56.08 arc mins, so you can see it's quite small. 3 Quote Link to comment Share on other sites More sharing options...
paul Posted September 15, 2021 Share Posted September 15, 2021 A fascinating object and a great result! It's really tempting me to switch back to the Newt and have a go myself 🙂 but I need to spend time with my 70mm and more wide field stuff.

Thanks Paul I want to use my 80ED to capture some of the bigger targets, but I don't want to strip my current setup down, I still have numerous targets for my 120 to capture.

My Esprit 120 was a bit pushed with this one, it's extremely small, but the long integration time seems to have brought out enough detail. 1 Quote Link to comment Share on other sites More sharing options...
