While out observing last Saturday with Barry and Curt I had the Polarie with the Nikon D800 and a 50mm lens going for 60 x 1.5 minutes at iso1600 and f4. I'm reasonably pleased with the result, as it shows most of the interesting features in the region.
However, 60 x 74Mb raw files sure put a strain on the processors!
Thanks for looking, hi-res version at

Looks nice Andrew.

I shot some Ha of this region with a 50mm lens on my QSI on Saturday. Yet to be processed, but the Individual subs looked OK. I was amazed I could actually see definition in the horsehead with a 50mm lens!

Very deep. It looks like you picked up a lot of green airglow there.

Superb Andrew. You've got all the main candidates in one. Love it. :thumbsup:

Thanks David, I look forward to seeing that. I lost a fair bit of detail with denoising, but was similarly impressed with what a good 50mm could show.


Thanks Greg, I took a couple of wide fields at 14mm as well and there was plenty of it about. It was also doing damage to the contrast in the eyepiece.


Cheers - I was kind of hoping I could just crop them out of the final image to save mucking about with the bigger AP setup, but unfortunately not even the mighty Nikon is that good :-)

That is a very impressive wide filed. :thumbsup:
Yeah, you can see the 43mm sensor size.

If you have PixInsight, try to use SCNR-G(green), roughly 0.8, and I’d also use col-saturation to boost the pink-reds … ;)

Thanks Ian, I had tried the SNCR but not at 80%. I think 5 minute subs might deliver the best improvement though.

Great looking widefield Andrew.

The high resolution shows so many objects.
