I took the new (second-hand) lens out into the garden to try to capture a closer shot of the moon than my very old 75-300mm lens used to allow. I stacked three of the clearest shots in Z stacker. I’m not sure how effective that was, as the stacked final only looks marginally clearer than the original sharpest image. I have compared it with an old shot of the moon I took in September with my old 75-300mm lens.
I’m looking forward to taking more images of the moon, on clearer night than this (it was a bit hazy).
The original images (below) was f/9, 1/100, ISO 100, at 400mm on a semi-cloudy night.
