The nearest pic I could find was here:

Thanks, Allan. CTA 1 isn't in Vela but that's a great APOD image.

Colours are excellent well blended.
Was it difficult to pull the OIII data out?

Thanks, Michael. The Oiii wasn't any dimmer than the Ha. There wasn't much of either!

It's such a pity that so many SNR's are either too small to see detail, too faint to see anything, or so close that they hugely overflow the field of view and have low surface brightness. Here, with lots of hours, you've done a splendid job.

Thanks very much, M&T! Our FOV was just big enough to catch most of the interesting stuff so that was a happy coincidence.

How embarrassing - I didn't know your target so I put
CTA1 supernova remnant in to Google images & the one I saw was the 11th picture down.

cheers

You have to look pretty hard to find an image of CTA 1

That is a cool looking view Rick. The addition of the planetary in the field adds a lot of extra interest. Nice work again.
