Hi all,

Here's another from my stay over at Zane's observatory.

Read and view here.

Warning: file is approximately 1.25 MB in size.

As always, comments and critique welcome.

as always, the presentation is superb and I love the nebula!

with some of the brighter stars, they seem to have dark lanes at opposite ends to each other - what would cause those? almost like negative diffraction spikes.

I really like looking at this!

lovely image H, but could you enlighten me as to the split halo's of the brighter stars? did you have something on/in the optical train to make that?

Wow a very nice image once again H!
I've always liked this nebula.

Another fine image, H.

What bright star is causing the massive flare in the lower bottom right?

Thats a great image Humayun, fantastic colours.

I really enjoyed that one.

Impresive image Humayan.

Nicely taken and composed.

Ken · #11 10-12-2006, 11:16 AM

Very nice image Humayan, this must be a very faint object I have looked for it visually a few times and seen nothing. Clear skies Ken

David,

Cheers, mate.

I have absolutely no idea what's caused them. I'll have to speak to Zane and see if I can find an answer. It didn't happen in any of the other images that I took with the exact same configuration.

Thanks!

Regards,
Humayun

David,

Thanks.

As mentioned to davidpretorius, I have no idea what's caused them, as they didn't appear in any of the other images taken with the same set up.

My only guess is that it could be caused by the reflection from Rigel in the bottom right of the screen? I don't know how, but, that's my only guess.

Humayun

Mike,

Thanks, again.

I'm not entirely over the Moon with this image due to the reflection from Rigel, but, there's always next time.

Humayun

Eric,

I haven't got my camera modified just yet. The equipment I used was Zane Hammond's (astroboy) at Magellan Observatory.

I may end up modifying my camera myself as Dave Burren seems to be very busy.

As for difference, there's a massive difference! It's worth it.

Humayun

Andrew,

Thanks, mate.

It's an interesting object. I think there's some theories which say that it's a part of Bernard's Loop, whilst others say it's a supernova remnant. In either case, it makes you wonder what happened up there to cause it.

Humayun

Mike,

Thanks!

The reflection is from Rigel. I thought that perhaps some kind of gradient removal would remove it, but, I had too much difficulty, so just left it in. I know it detracts from the image; I'll have to redo it some time.
