Homunculus nebula

[kosborn (Kevin)]

This is a detail view of the Homunculus Nebula surrounding the star η Carinae. The detail image is a cropped and drizzled image taken with 120 subframes of 5 seconds each through a Ha filter. It overlies an image of the Carina Nebula I took earlier this year. At 1270mm focal length there is only a hint of bi-lobed structure of the nebula that can be seen at longer focal lengths. Twice the focal length would have been much better! A bigger image is available on Astrobin.

Beautiful field. Details and colours are outstanding. One for the poolroom.

Kevin,
Great effort there trying to expose the Bi lobe behind Eta
Well done !!
I saw the Bi lobe last year behind Eta for the first time on a moonless night down south , using my 12” Goto dob and Televue 21mm ethos eye piece. It appeared as a faint holographic sphere behind the Star. You have to apply averted vision to see it , quite amazing.
I had to look twice to prove I wasn’t seeing things

Cheers
Martin

Wow!! Nice shot mate. Really sharp! Might even be some more of the lobes revealed with shorter subs perhaps.
Your shot has reminded me that I started working on a long fl image of the bipolar lobes earlier this year but haven’t yet gone through all the data so thanks for the reminder!

Thanks guys. At 5 seconds per sub it didn't take a lot of effort although processing was surprisingly difficult given the high dynamic range. I look forward to seeing what you put together with your data Dave.

I'm a little ashamed to say that I've never put an eyepiece into either of my scopes. There has only ever been a camera hanging off the back. I'm planning some trips to dark sites soon so maybe I should give visual a try!

Lovely image Kevin, not overly done, and very natural looking.
