M13 - Deep Reference Image from DSS POSS-II Data

[Noel Carboni]

For a long time I've wanted to see what's in the Digitized Sky Survey for M13... Ideally I wanted to create a very, very deep image that shows virtually all of the hundreds of thousands of stars in M13. I think I've accomplished that goal.

The DSS data, originally taken on photographic plates some decades ago, is very good as usual but for one small flaw: The core of this fairly bright object is completely overexposed to white. Not wanting to give up on the project, I added in my own (much shallower) high focal length M13 exposures, and voila: A super-deep image resolved (well, kind of) to the core.

This is a 1 degree square field from red and blue POSS-II plates, synthetic green channel courtesy my actions, plus core data from my own exposures. Click on the image to see a high resolution version (warning, large file).

Sure is a big file Noel, but well worth the wait downloading (thats me computer wallpaper sorted for the next few months:thumbsupmate: )
Amazing detail and you've done a great job mate, never seen a globular image that has so much detail in the core as well as the extremities:welldone:
Excellent stuff..........

Waaaa! Waaaa! Sob! Oh where is my broadband connection?

Noel, I will have to check this image out when I get back to 'civilisation' (and I use the term with some reservation!).

Another great image from you Noel. Makes my own feeble efforts pale into insignificance. But am slowly getting there. One small step and all that jazz

Getting the NexImage up and running has opened a door of opportunity all I need is some clear and unadulterated skies Which means going bush.

Eat your heart out Jim Only took me 12 seconds to open. :Chessy_Smile:

Fair go Dave, that's salt in the wound, a cruel twist of the knife, a kick in the cods, etc.! (My eyes are watering at the thought of it!)

Watch out if ever I'm in your patch - I'll be 'round to borrow your connection to plug in the laptop and then spend hours, no, days ignoring everyone and everything else in the vicinity! ;-)

No probs Jim.. We have spare sockets on the router. I will even lend you a tissue to dry your eyes... As they say if you can't take a joke you shouldnt live a 1000 k's north of Woop Woop :Chessy_Smile:
Have fun ....

I'm not exactly sure where Woop Woop is, but sometimes we get the feeling up here that our distance from the (un)real world is measured in time, so we set our watches back 20 years! ;-)
