I've been getting in a fair bit of practice doing NB processing of late, struggling to get decent, CHEAP data out of iTelescope while waiting for my new 10 inch scope components to be constructed (Mr Royce works VERY slowly and carefully!).
In the meantime, Andy innocently asked why i didn't use Hubble data for practice, it's free too. Well part of me still likes the perverse challenge of getting good data, 'personally', out of iTelescope. Believe me, it can be a big challenge, see my next post as an example, shocking noise with few subs.
So Andy's question got me thinking. I'd previously had great difficulty in finding decent, easy to navigate Hubble data. So some quick googling to update myself revealed THIS amazing site!

Be warned, the site doesn't work on mobile devices. And apologies if there have been other posts raving about this...
But on the PC, wow, what an easy to use system.
On the first page is a very informative instructional video:
Those with limited internet connections need to watch out, the superb data files from Hubble etc are massive, each sub being around 200-400mb. Oh what data!
Anyway, here's my first processing effort, details in the Flickr link:

Also attached is the image scale involved, ridiculously deep, and this is the Widefield cam!
Those with eagle-eyes (*cough*, Mike!) may notice strange noise artefacts, I did! If anyone knows if Hubble has a darks library and where it can be located, I'd love to know. It's a little bit of a pain to pop up and take a few in person...
Enjoy playing!
