Spot lights on Corona Ausralis minus the noise

[strongmanmike]

Thanks for all the nice comments regarding the first versions guys but tonight I changed my mind and although it wasn't too bad the noise was in fact slightly bothersome in the first versions after all :whistle:

No substitute for having lots of data in the first place (as Jase said 30min Lum is just not enough) but just shows what modern image processing techniques can achieve if you are pressed for time :thumbsup:

Full frame image (1.2meg)

Close up crop of the best bits (600K) - ie narrow field Fred! he he he

If you are on dial-up try this smaller full frame version:

Hope these look more pleasing?

I like this version much better!!!
Very nice Mike!
I love the detail showing in the whispy reflection neb!!

Nice rehash Mike. Certainly an improvement. I still think you should try a mosaic of the area with the Starfire sometime. Would look sensation at that FL as the field is not too narrow.

Very nice indeed.
How long do you do each subexposure with the proline?
Thanks.

Nice work! ;)

P.S. Thanks for the dial-up version I apprciate it.

Thanks Arthur, itisa beautiful area of teh sky that's for sure so it's easy to make a nice vista out of it really.



Thanks Gary I hsould have removed the noise the first tme but I processed at night when the noise is less obvious



A Mosaic..? When I have an observatory and I'm permanently setup I may just do that! :thumbsup:



Hi Scott, my subs these days are 10min mostly. I will ue longer exposures once I feel I am out of the testing phase. Using the same exposure length just helps with callibration as I can use all the same callibration frames each time...lazy :D



Yep I'm on dial up too and sometimes I just can't be bothered to wait for an image to download if someone posts it too large and I usually say to myself I'll come back to that and often never do :( . I think 500K - 1meg is sufficiently large for most images to still show enough detail and not be so big that dial up folk don't give up :)

Hey Mike,
I liked the effect on the first post with the optic distortion on those 2 opposing stars which seemingly shed light upon the object... that was very interesting.
Personal taste, I didn't think it was overly noisy.

I like this crop version too.
Definitely shows what can be done when hard pressed for imaging time.
I think the scope and the camera have a large part in helping to achieve such results in a short period of time.

Nicely done!

All the best
Rich
