Yes, I think that is the what I need. I found one by Maude, very similar but cheaper. I will look into getting one when I return from this trip.
Meanwhile, clearly the easiest ,cheapest way is your digital photography and software to work out pixel distances. I’ve never done this, so any advice on how/software etc would be welcome.
Many thanks to you and Bill for all your advice. I will keep you posted on any progress, or otherwise!
P.S. Have you done lunars with camera, lens and pixel count to measure LDs?
If so, what results? Any details of how it is done etc.
The micro guide eye piece might be what you are looking for or something like it that fits your telescope. There is a calibration process. See PDF. I saw one for $135 US.
