[Leica] IMG: comet NEOWISE

[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.

I like these programs a lot - but if you don’t want to die of old age you need a SERIOUS graphics card. Each application pegged the processor in my card for about 30-45 seconds at a time.
