Prawn widefield

[Atmos (Colin)]

This is a crop from my larger mosaic I’m working on, I think this is about 16 panels.
It has the FOV of a full frame DSLR and a 170mm lens.

Higher res version

I’m estimating of about 4 hours of 300s exposures at ISO400 with my D810 and Sky Rover 130mm.

Wow! The hires is gorgeous! Sub zero cool.
Just realised the dark tower is really nice in RGB.

Go Colin!

Excellent work. I am loving these widefields. Mosaics are hard work. I need to master the mosaic grid tool in Sky X as I tend to spend too much time working out where the next panel needs to be!

Thanks Marc
The Dark Tower is more recognisable in not quite so wide fields and in Ha. I didn’t even notice it until you pointed it out

TSX mosaic grid tool is AMAZING! I’ve used it for my last handful of mosaics and it’s done the job flawlessly. It took me a little while but I managed to figure out how to get the output file from TSX into a language that SGP can understand. I can setup 40 panels to be imaged in a matter of minutes now and SGP loads them as a target list.

Why is the skt so dark when all this is up there! Lovely.
One question from someone just starting to try mosaics for the first time. Why set a mosaic up in something else to export to SGP when the latter can do it?

That’s because our eyes are tiny and the sky is huge

SGP mosaic wizard is good for smaller areas but I’ve found it cannot handle areas larger than 10-15 degrees.
Take this 15-18 panel mosaic, it isn’t a lot of panels but it takes up a 60° FOV. I had to create this in TSX as SGP simply couldn’t handle it.

That's fabulous work Colin.

I love this part of the sky.

Nice work Colin - I particularly like it in high res

Nice work, Colin! The low res on IIS doesn't do it justice, higher res on Astrobin looks much better.

[topheart]

Just awesome!!
Well done!!
Cheers,

Thanks Lee, it looks better closer to native resolution but that’s a pretty dang big image

Nice one ColinAnother epic image. Using this as a finder chart for some interesting stuff you have shown up
Many thanks

[Ryderscope (Rodney)]

Beautiful work Colin.

[strongmanmike (Michael)]

Lovely field that Col, vibrant colour and a nice mix of textures too, top job

Trish: Wow! The Prawn leaps out. The colours are perfect; beautiful nuances. Long live Nikon. Love the composition.

Mike: What prawn?

Trish: Put your anti-colour-blind glasses on, you idiot.

Mike: Wow! Look at the Prawn!

(Bought a pair of $600 anti-colourblind glasses from the US. They were useless, made it worse if anything. Bought a $12 pair from spotlight. Fantastic!)

[Benjamin (Ben)]

Gosh. A beautiful image at all scales. Love all that wonderful colour and complexity.

That’s one of the things I love about large mosaics David, they can be used as a reference. It has some complex distortions that I haven’t tried removing yet so it isn’t astrometrically correct but I’ll be fixing that in the long term.

The FOV is even too wide for your FSQ!

Thanks Mike and Trish Trish is of course correct, long live Nikon!
I kinda understand what you mean Mike, I bought a pair of sun glasses a few years ago that we’re supposed to do a better job of reducing glare without being polarised and I thought it could be good to use at work. What I found is that it made some green hues almost invisible, the same green colour as some weeds in fact making these glasses less than optimal for my job as a gardener haha

Thanks Benjamin, there is just something about large mosaics that cannot be captured in shorter focal length shots.

What a wonderful field....excellent work Col
