[Leica] IMG: comet NEOWISE

[hlritter at bex.net (Howard L Ritter Jr)]

Nice, Adam.

Here?s my recent attempt. I took dozens of images at each of several FLs, 
and I?m going to try stacking them to improve the S/N ratio and reduce the 
color noise that comes from taking exposures of several seconds at ISOs in 
the thousands. Nikon D810A, Nikkor 80-400 zoom.
