This is my first attempt at processing a mosaic image.
It is a 6 panel mosaic, each panel 4700 x 4700 pixels.
After final cropping the full size image is 11333 x 7430 pixels.
Data was aquired from Hubble Legacy Archive
(72x509 10.2hrs).

Full Size Image - Click image, then in upper right corner under "View" select "Full Screen"

Really nice. Having tried some of the Hubble data I can appreciate the time you probably put into this.

Thanks for sharing,

Dan

Beautiful. That's one of my favorite Hubble images. Thanks for posting. What is the original size of your mosaic?

Thanks guys for looking and the compliments!

There are 6 panels 4700x4700 pixels, 259MB each. The original mosaic (FITS) before cropping was 1.2GB. After processing and cropping it is 11333x7430 pixels (987MB). The full size JPEG conversion is 40MB.

Pretty seamless work I'd say! I didn't read all the way to see it was Hubble, I was thinking I want that OTA!

Thank you! And yes wouldn't it be nice if we could all reach out like that?

I read the title and thought what type of scope do you mosaic the Sombrero. Hubble... Of course.

Great process!

That's spectacular - well done.

I agree - try for an APOD.

Thanks guys, I uploaded it to APOD submissions. I don't have high hopes though. Sombrero has been APOD a few times before. Not to mention my submissions haven't been able to beat a Quilt so far! HaHa! :grin:

Very funny - how did a quilt get there?

Seriously - it's hard to know what to do with our hobby -
I have more than $10,000 worth of equipment but I have to
drive a long way to get dark skies & my results still
can't compete with other's who have
$50 grand or 150 grand of equipment so why
not use data from a mult-billion dollar system?

More people should use Hubble data.

cheers
Allan

Merci Alexandre. Je fais de mon traitement sur un ordinateur portable avec la luminosité tourné un peu. Pendant le traitement final j'ai essayé d'obtenir la luminosité / contraste aussi haut que possible sans lui donner un look blanchi. C'est le meilleur que je pouvais faire. Peut-être que la luminosité de votre moniteur est un peu faible ou la mienne peut-être trop lumineux. Merci encore pour la recherche.

That is a great image of M104! You can easily see the other side.

Interesting process approach, can see some fantastic detail even on the backside.

With my 314L+ in for repairs, I might hit up the HLA. If I can remember how to find data sets, been a while since I looked.
