Relief about the Moon at 2X...
6

For some time I was feeling dismayed about the combination of SD1M + 50-500 DG OS + Σ2X converter. I could not get it to focus at infinity any more!!! It would work on other lenses, but not this one. I blamed eyesight for not being able to see fine focus, etc... - Sure, AF is much easier to use! So I gave up using it altogether for over a year, as it does not allow Autofocus anyway, But in the past few days I accidentally/just/somehow remembered to switch OFF the AF. Of course, it then worked - sharp focus at infinity!

As a bit of a celebration (and conveniently forgetting that I had forgotten about the AF switch for so long) I tried it on the Moon yesterday afternoon. (This had been my bane for a year or so!). In these few days, clouds permitting, I will give the planets a go.

Moon (with no attempt at noise reduction)...
