View Full Version here: : Emu in the Sky
18-06-2012, 02:54 PM
Just an initial rough process of the Emu taken early this morning in Leyburn. Lots more work needed - I thought I'd make it a PixInsight learning project one day.
I'm loving what the cold weather does for stock DSLR noise reduction - almost everything was covered in frost by the time I called it a night.
Emu in the Sky - larger version (http://itee.uq.edu.au/~davel/MilkyWayWideWeb.jpg)
1x 900 sec, f/8, ISO 1600 taken with a Canon 5DmkII + 14 mm f/2.8L II piggybacked on an EQ6 Pro + GSO RC8 + Orion mini guider.
(Big thanks to Ray and Steve for macguyver-ing me a piggybacking solution in the field yesterday!)

Nice capture Dave. Glad to see you got some data after Saturday night's dismal weather.
Hope to see you again at Leyburn next month.

Thanks guys! (Three Davids in a row?!)
It's amazing how much atmospheric refraction there is on the corners. Even with autoguiding and very good polar alignment, I can see the left/right edge stars elongate with successive shots (but the centre stacks perfectly).
Hope to catch you at Leyburn again soon.

Nice image Dave,well done!,unfortunately Saturday night has been the worst seeing over the last week.We were up till 2 am gathering and testing gear when we could.
Have you cropped this image?I did an image like this once using a 10-22 mm EF-S lens on my 50 D (at 10 mm)and from memory it appeared a wider angle view than your,doing the math-my focal length would re longer(16 mm on a crop) than your 14 mm on your 5 D 2.

Thanks Chris & Lester. We were totally clouded-out in Leyburn on that Saturday, so I guess you were lucky!
Chris - It's a full frame image... I don't remember cropping much/any of it. You made me curious so I dug it up... is this (http://www.iceinspace.com.au/forum/showthread.php?p=750215) the image you're referring to?
The fields of view for both lenses are quite similar - 10-22 has a 107 degree diagonal field of view vs the 14 mm's 114 degrees. I see that your image didn't include Crux, whereas mine is cropped at Lamb Cent Neb... but yours includes slightly more of the Milky Way on the other side.
