Orion Rising

I had the opportunity to image Orion last week early in the morning.
Conditions weren't ideal with wind and high cloud spoiling most of my frames and the moon was at last quarter.

Picking out the best from around 30 frames, I ended up with only 5 usable ones and ambient temp was relatively mild so the frames were quite noisy.

Details:

Canon 20Da, 50mm @ f/3.5, ISO 800, 5 x 90 sec exp (ICNR), EM200 mount.

You can view a larger (1.2 MB) image here (Press F11 for Full Screen view): http://tinyurl.com/287kq2

I was hoping for a better result using all the frames but it just wasn't possible.

Thanks for looking, C&C welcome.

Thanks guys.

Yes I was surprised that at 50mm FL you can pick out the objects in Orion.
Here's a crop image of the main area with the labeled objects.

You've even got M78 in there.

Is that the 50 f/1.8 or the 1.4 RB?

A very pleasing wide field vista Andrew. Well done. Shame about the gradient sloping towards the lower right of the frame. I think this is what is holding back the intricate details of Barnard's loop. Also check your histograms, the data is black clipped in the blue channel hence there aren't many vibrantly blue stars present which is common in this region. When I stretched this channel, I noted the gradient wasn't as prominent.

Thanks Jase, I think the gradient was caused by the stray light from the last quarter moon as these were taken around the time the moon was rising.

Also thanks for pointing out the histogram, that one snuck by me on the last few steps of processing since I usually keep an eye on it.
I had a quick look and did adjust the clipping and there was a marked improvement (attached).

Cheers for that.

I think you can be proud of your captures Andrew.
Can you imagine what more frames will do as well as a really dark night.
A very good wide field.

Glad you like it Ric, Alex and Eric.

Alex it was heartbreaking to only use the five usable RAWs out of the 30 taken in total.
The high cloud was just enough to ruin most of the shots and as you say I could only imagine what more frames would have yielded.

Still I consider myself lucky that I got what I got out of the session and it's all fun anyway.

Cheers.
