That's a fine result.

Very nice, Greg!

[gregbradley]

Thanks Larry. It was nice to take a different approach to imaging for a change.



Thanks Narayan. DSLR widefield imaging is quite involving with the night sky so I like that about it as well.

Noice Greg :thumbsup: looks a tad washed out on my screen (now adjusted (http://www.pbase.com/strongmanmike2002/image/55347254) :P) but lovely stars across the frame :thumbsup:

Yes - looks a bit bleached but a great shot.

[David Fitz-Henr]

Yes, quite nice Greg - amazing what can be done with a DSLR and relatively short exposure time :thumbsup: Perhaps a mosaic next ...

[multiweb]

Anther great shot Greg. Nice framing. :thumbsup:

[DJT]

Agree with Marc et all, great framing and a lovely image. :thumbsup:

[RickS]

Lovely wide view, Greg. Another triumph for the D800E :thumbsup:

[gregbradley]

Yes agreed. I was thinking about it before I read this and just posted a higher contrast version. More exposure time of course always is a good thing. To some degree this is just experimentation with the DSLR. If I get a nice image I can concentrate just on that and set up the intervalometer and go to bed! Unfortunately this is a 4 in the morning scene.



A mosaic - hmm not a bad idea, I like mosaics.



Cheers Marc. Doing an allnighter with a DSLR was different to my normal imaging routine but I didn't take my astro gear to my dark site due to cloudy weather forecast and then I had 2 glorious clear nights!



Thanks for that!



Its an absolutely amazing camera. I thinking about getting a D600 as a 2nd time lapse machine due to limited time available to get the time lapses up. I'll see how the Sony Nex 6 works out first.

Greg.

Very nice! You don't seem to suffer from airglow... is that due to the short exposures or great skies?

[jjjnettie]

It's an amazing region of the sky. :)

[gregbradley]

Cheers JJJ. It sure is.



I don't know Dave. I associate airglow with widefield images usually. I have noticed occassionally with deep sky shots there would be a bit of green and I wondered where it came from. It varies.
The skies at my dark site usually are very good though.

[Ross G]

Great looking widefield photo Greg.

The D800E is proving itself an outstanding astro camera.

Very nice shot Greg.

[mbaddah]

Wonderful image! What focal length was this imaged at?

[gregbradley]

Cheers Bob. Thanks for your compliments.



Thank you for you compliment.



Thanks Ross!
It is an amazing camera. It has relatively reasonable Ha response as well. Not as good as a modded camera but better than I expected.



This was 70mm using the wonderful Nikon 24-70 F2.8 ED lens which is one of their pro lenses. I use it a lot. It has superior coatings and gives a fantastic rendering to images. Its almost as good as a prime.
What I am also now discovering is it has really low chromatic aberrations compared to other lenses. There are 3 main Nikon pro lenses often regarded as the holy trinity - the 14-24mm F2.8, the 24-70 F2.8 and the 70-200mm F2.8ED. Canon has excellent equivalents except for the 14-24 at this stage although I read that they were developing one which is exciting for Canon owners. There are adapters that let you use Nikon lenses on Canon cameras so its no problem that way. I have one. Its made by Novoflex. A bit expensive but very well made.
