I have a 77mm Leica scope I purchased from you several years ago.
While the 20x60 zoom eye piece I have now is working fine, I was wondering if the new 25x50 eye piece will fit on my scope should I need a replacement at some point.
I also have a question about the write-up on the page about digiscoping. Under the heading about not making the mistake common to beginners of cranking up the zoom, there's a reference to using fixed, wide angle eye pieces.
Though reference is made to the fact that these eye pieces have fewer optical elements and therefore may let in more light, the article seems to dismiss this feature and quickly goes on to say that most experienced digiscopers use 20x60 zoom eye pieces at 20 power and get excellent results.
It's been my experience that most people buy use a zoom eye piece when they purchase a scope. So the number of people using a fixed 30x wide angle eye piece is severely reduced relative to the number of people with scopes in use.
This is a long winded, round about way to ask, "Would a fixed eye piece give better results when used for digiscoping?" This question isn't really addressed in the article.
Thanks for your interest in Eagle Optics.
Unfortunately, the new Leica eyepiece will not bayonet onto the old Televid scopes.
Good question about zoom vs. fixed eyepieces for digiscoping. Certainly either can be used. In general, you will get a bit wider field of view through a fixed eyepiece, and that, along with the fewer elements aspect, will provide just a tiny bit of a brighter view.
I would agree that most people digiscoping are using zooms set at the low end. In part because most birders or nature people appreciate having a zoom eyepiece, and when you're not digiscoping, it's nice to be able to use the zoom for detail.
Assuming eyepiece quality is comparable, I'd argue that there's not a world of difference between fixed vs. zoom eyepieces for digiscoping.
Again, either can be used, but most folks go with a zoom for detail, and simply set it on low power when taking pictures.
I hope this helps, David. If you have any further questions, feel free to email or call the Eagle Optics staff.
