Rivers of Gas

My fascination with the Vela Supernova Remnant continues.
It took me a while to locate this part of the nova. It shows up best in O111. But it is nearly invisible in less than about a minute exposure so a lot of trial and error to locate the interesting parts of the nova.

What an amazing amount of debris left over when a large star blows up. Huge amount of stuff. Just shows you how highly condensed stars must be.

TEC180FL, FLI PL16803, Tak NJP mount.
Astrodon 5nm O111S11HaO111 140 130 130 Ha was 1x1 binned and O111 and S11 were 1x1. I think its better to do 2x2 even on the Ha
and I did that on the last night imaging the Nova.

Another really top image Greg

maybe a mosaic of the whole area could be on the cards ???

Electric dreams of neural networks.

Exquisite. Just the right focal length.

Wow, I had to go back and look at it a second and a third time. What a depth of field you have given it Greg. I can almost touch the foreground veil. Beautiful shot.

[Bassnut (Fred)]

Thats really cool Greg, detailed and smooth .

Red (SII?) seems to have left some star artifacts. As an alternative view, ive clipped the background to isolate the cloud structure, sorry about the low res.

What can one say?
Well I'll say it...........awesome.

Here is your lovely picture on my HA widefield Greg. I think you have a tad more resolution. Never mind the quality feel the width!

I like it.

[spearo (Frank)]

Wow!

That would have to be one of the most amazing parts of the sky thanks greg for taking us there.

[Craig_L]

Amazing!

[AG Hybrid (Adrian)]

brilliant!

[jase (Jason)]

Punchy details Greg. A not often seen sight of this vast complex. Thanks for sharing. Well done.

[leon]

Excellent work Greg, very punchy sort of stuff, and a joy to look at well done.

Love it! This area has so much potential but gets overlooked by alot of imagers!

Thanks Trevor. I'd like to do a mosaic once I have my home observatory up as it would take a few weeks probably. FSQ106 with its reducer and the 16803 would be the choice or perhaps even AP140 with its reducer would be even better.

Thanks for that. That is the idea the image evokes for sure.

Its the O111 that has all the detail. It seems a lot of these objects are best in O111 - like Thors Helmet.

Thanks Fred. I'm actually redoing it using median combine rather than sum combine which leaves too much rubbish in the shot. These sensitive chips come at a cost of lots of little cosmic rays that you don't see in STL11 cameras. So median combine is my only choice for now unless there is some other way of cleaning them up. There is very little difference between median combine and sum but on this one I thought I saw a slight improvement in detail from sum over median but the cost is the artifacts which takes a lot of healing tool.

Red (SII?) seems to have left some star artifacts. As an alternative view, ive clipped the background to isolate the cloud structure, sorry about the low res.

I fixed that now. Got rid of the red. Not sure where that comes from. I suppose S11 must see some stars that Ha and O111 don't?

Thanks David, I appreciate.

WOW!! That is beautiful Greg, thankyou .... and now my wallpaper

[multiweb (Marc)]

Beautiful part of the sky indeed. I can see why it's one of your favourites. Top shot.

Thanks Humuyan. It does evoke those sorts of image.

Its the O111 that has all the fine detail. Ha has some but O111 is the bulk. S11 is quite detailed as well which surprised me as it is usually the most bland.

Thanks Fred. I fixed those red stars. Not sure what causes that - S11 lets some stars through the other 2 don't? Anyway a bit of colour range tool fixed it.

I'm in the process of redoing it from the ground up to use median combine as these newer sensitive chips really pick up cosmic rays and sum combine lets these little squiggly lines through and median combine filters them out. The slight extra detail of the sum combine (not always any difference though) isn't worth the rubbish it leaves behind.

Thank you very much David.

That's amazing how you do that Bert. I see I lucked out in that that was the exact area I wanted to image as it looked like it had the most detail in it for O111 and Ha areas. I was hit or miss though as I wasn't sure where I was in the field. I guess the hour I spent trying to find it was worth it. 1 minute exposures just to frame it. I wish the Sky V6.0 had Vela in it - its a hell of an omission.

I think its one of the best areas of both the northern and southern skies.

Its quite a dramatic part of the sky. The vastness of the explosion is mind boggling. Lets hope one of these stars doesn't blow up near earth.

I wonder if there is dangerous amounts of energy left in these shock waves or is it all dissipated by now?

Thanks Gary. Its not well documented in software and it is virtually invisible to anything less than about a minute exposure so its a tad hidden.

It sure is my favourite. Rob Gendlers image is a reference image for me. He has done the best job of it. FSQ106N and STL11 on a Paramount ME in Bringelly is what he used and the sky 6 and the mosaic tool I imagine for software planning and execution of the mosaic.

Outstanding work Greg
