Last night for the first time since buying my Nikkor 85mm F/1.8G months ago I had it under the stars. I have done a fair bit of testing with street lights and the like seeing what the coma is like at various F/Stops, it works remarkably well!
Taken with my Nikon D700 + Nikkor 85mm F/1.8G @ F/1.8 with 60s exposures. There is a slight mismatch along the RHS of the image that I decided not to crop because it does contain a fair bit of ISM. In fact, it is showing up reasonably well on the whole lower RHS of the image. I was pleasantly surprised to see it after I ran the DBE.
Took 35 minutes to Linear Clip stack all 122 exposures, longer than I expected! Might try a Windsorised Sigma Clip to see how that deals with the data yet. All in all, quite pleased. I thought that I'd missed the focus but I am getting a FWHM of 2.8 pixels which is about the best I've ever achieved with this camera, thought the F/1.8 imaging would have been more painful than it was.
