Francis,
The 200 mm prime lens is the largest that I can hand hold steady.

I'm in awe! And extremely jealous! Great moment, great pictures, fantastic lunar longitude! All this within a week of your fantastic 3 body fix! Whow! Thats a couple of bucket list items for me too, yet to be ticked off. ( terrible weather, 2 weeks thick cloud here. Anyway not our turn for the Venus occultation in Europe.
Question please.
1) did you use a 200mm prime lens? If so, is that essential? I only have a zoom at present and Santa refuses to add anything else to his slaigh.
2) I read somewhere, I think Letcher,that you should avoid Venus and Mars for lunars because of complex parallax problems? Presumably not so and Frank's calculator seems to have done ok?
Keep up the fantastic work.
Best wishes
Francis
