If you don't mix up with the two-speed focus in one wheel, your Harpia is not like it should be.
Thanks Ian, a very interesting read. I was saying yesterday that I need to look for a digiscoping adapter for my iPhone 5s. Zeiss do one for the Harpia but it's for the larger iPhones.
I do live in Flamborough so yes, I'm very lucky that I have some great birding right on my doorstep.
Send me a PM with your address and I'll send you my old Iphone 5s adapter but you'll have to get the dedicated collar from PhoneSkope for your Harpia eyepiece. (By the way if you want to see examples of my photos go on the gallery....on British Birds and I've posted plenty of shots there).
Did you usually used the 25-75x zoom ep on your ED82?...
Having used a Nikon ED 82mm Fieldscope for the last 10 years, my 'normal' way of focusing doesn't work with the dual speed focus arrangement of the Harpia and therefore it left me thinking that the focus at 70x zoom wasn't working correctly. This would explain the results of the star test which I did as I wasn't actually using the focus as I should have been. I've done a seawatch with the new scope tonight along with a friend who has many years of experience with optics and he has tried the Harpia himself. He can see the problem I have with focus hunting at full zoom and we both agreed that when you are panning at 70x zoom and trying to focus at the same time on a bird which is miles away. It's just too much to expect to be able to get a sharp image.
Did you usually used the 25-75x zoom ep on your ED82?
I use a 30x wide angle eyepiece 95% of the time. I have a 25/75 zoom but prefer the field of view and brightness from the 30x. When zooming in with the 25/75 the field of view shrinks and darkens quite a bit. Most of my birding was moorland stuff before moving to the coast and the extra field of view was very useful when scanning around for distant birds.
