Very nice! Last night was stormy here in NY, so was only the 2nd night in the past week or so that the Moon was not visible here.

With effective 1400 mm on FX, I estimate that the Moon's diameter should fill about half the frame height. Thus with a D600 you should be getting about 25% higher pixel/arcsec, in addition to the much larger telescope aperture (~2X), than I am able to achieve with 600 mm on a V1. How is the detail in the full size photo?

How much benefit do you get from stacking? I have been trying to stack several images to help compensate for relatively poor viewing conditions (lots of haze, moisture and thin clouds) here recently. So far I have found diminishing returns after stacking beyond about 3-5 shots. However, don't have much experience with stacking. What software are you using to stack your shots?

Gerry

This image is not cropped.

I use Registax. I'm still on 5.1 because I haven't figured out 6.0 yet.

Hello Ken,

There are nights where She is the only neighbour I would
like around. Like last night…

Next time, I'll remember where yours is…
really a beautiful neighbour you made there!

Have a good time!

Nice job, Ken!

Did the stacking improve things over the sharpest of the 17 images? Which stacking app?

Yes. Registax 5.1: I haven't mastered Registax 6.0.
