Stiched job The Ghost and Iris

[peter shah]

Finally got around to processing this mosaic, ive had quite a bit of trouble balancing the colour and getting a smooth join between the two...im pleased with the way this has turned out

Thanks for looking

peter

[robbie c]

Well I cant see the join! very nice Peter

[Tom OD]

Looks good Peter, I can't see any join in there. Do you have a bigger version?

Tom.

[peter shah]

Yep here is a higher res version astropix.co.uk

[foundaplanet]

That's a real nice one to look at

Peter thats a brilliant mosaic, Iris is one of my favourite nebs and it looks awesome like this! I can see a satellite trail or some line near the Ghost? Would it be possible to get rid of it? Even so, this is a really great image and the high res version is fantastic

The bigger version is very very nice! Great job!

[Fenriz]

Fantastic mosaic Peter, just how many star are in there?

[peter shah]

Many thanks everyone, the higher res version is still only at 50% it took a while to get the balance right im glad i stuck with it

Jamie i did notice the sat trail, and i will sort it, there were two others in the shot which have now gone just missed that one

Hi

Very nice peter must get you to try pixinsight would have stiched it in a few seconds

A wonderful mosaic of a fascinating area of the sky, Peter.

Incredible Peter - Simply incredible... (as usual!). I noted your exposure times (5 hours 15 mins of Luminance 17x530s in Blue, 14x600s in Red and 14x420s in Green) - Can I ask how you decided how many exposures of what length to use (and what length the luminance was?). I'm guessing a G2V calibration might be involved somewhere(?)

Yep these exposure ratios gives me an aprox G2V star callibration so thats where the exposure sub lengths comes from.

As for deciding how much is enough, with this shot i tended to give it a quick process as the frames as came in to see where the noise levels were, then moved on to getting the RGB, I was pretty short on the Iris really and could of done with at least another hour to clean it up a bit. The weather and condtions also play a big part on when i stop.

Harry stitching it in a few seconds sounds like heaven, it took a lot of work, one of the problems was the exposure difference between the two frames making me push it more and giving a slighty noisy right hand frame.

Cracking mosaic Peter....that would look great printed up at full size, framed, and put up on a wall

Cheers

Stunning image peter, just love the full (50% resolution) shot. I never realised the iris and the ghost was such near neighbours.

Peter, you should be pleased, that's amazing! Nice to see the context of the Ghost nebula. I agree you should get it hung on a wall, looks great at higher res

[Quatermass]

Wow I would be dancing in the streets If I could do something like this amazing job.

[ollypenrice]

Nothing beats putting images in context. Stunning, Peter. I must admit to gormlessly spending 21 hours on the Ghost without realizing how it really forms part of the Iris dust complex. Embarrassing! You have set me on the path to wisdom.

[peter shah]

I know what you mean Olly, Ive also been guilty until my GOTO packed up it made me look very close at where i was pointing the scope. With GOTO its like your're wearing blinders.

Excellent image Peter. Detail is great. Trevor
