Vela SNR mosaic

This is the latest image out of Clayton Observatories. Over the last couple of years I have been collecting data on the Vela SNR. At present I have collected enough data for a two panel mosaic. This mosaic contains 82 hours of data so far.

The actual field is extremely large, so much so I doubt I will ever get the entire field imaged at this resolution, but it is good fun to try. The field so far sits across the centre of the SNR and to one side. I invite you to swim around and discover the bubbles and knots of gas.

click here for larger resolution image.

Very nice Paul! As long as you can get a panel done per year you'll get there eventually

It looks wonderful. There are some very fine details in the gas tendrils.

Absolutely spectacular Paul. Fine detail and vast expanse all in one image. A beautiful image too: the colour and level of contrast are perfect.

Very impressive Paul! A beautiful vista for sure and well worth the effort!

But why so dark? Admittedly, I'm looking at it in a fairly bright room right now, but after a short play in PS it really pops!

Yeah good point Marcus. It was a little clipped so I think I have addressed this now. It looks more vibrant than before too. Thanks for pointing that out.

Much better!

BTW, my tweak was stars only mask->invert mask->moderate curves->75% blend.

Again, a great image!

Paul

you have certainly sacrificed FOV for resolution here with this camera/scope combination. So I am not surprised it will take you a very long time to complete the mosaic. What is the resolution of this system?

Regardless, some great detail and I was going to comment on the clipping but you appear to have fixed that.

Good job.

Martin

wow.. 80 hours on two frames. i think you're right.. there aren't going to be too many more panels on this one

what's the aspect ratio of the individual frames? even with two frames side-by-side the aspect ratio looks quite wide, especially accounting for some overlap between the two.

great result. very nice to pan around and the sharpness/resolution looks great at 50% view.

Phil

This system has a resolution of 2.10" per pixel.

This is cropped in an odd way Phil. I had some rotation from the previous panel and so I had to crop out several hundred pixels vertically. Hence why the aspect ratio looks wrong. My wife thinks it will looks good as a block mounted wall hanging. I might have to have an experiment to see if that works.
