IC 5146 and B168 with Nikon D810a

[Jerry_Lodriguss (Jerry Lodriguss)]

This image of IC 5146, the Cocoon Nebula and Barnard 168 was shot with the Nikon D810a astrophotographic DSLR camera on loan from Nikon for a review of the camera that was just published in the February 2016 issue of Sky & Telescope magazine.

This is a stack of 32 five-minute exposures for a total exposure time of about 2.66 hours taken from my magnitude 20.80 observing site in southern New Jersey. It was shot with a 5-inch refractor working at f/4.7 at about 611 mm of focal length.

The Nikon NEF raw files were calibrated with darks, bias and flat-field frames then aligned and stacked in Images Plus Images Plus v6.5 beta. The stack was further processed in Photoshop CC 2015.

It is very nice image and I love this PN also the dark nebulae. For my, I was just disapointed because I don't get the all dark nebulae but I had very good result with my DSLR Nikon D610 unmodded : http://www.astrobin.com/full/188737/I/

Now, I'm waiting to see your next image with this camera

Thanks guys for taking a look.

Franck, IC 5146 is not a planetary nebula, it is an emission - reflection - dark nebulae complex. I have more information about the object on my web page here if you are interested:
