Eyepieces

The subject: Spotting Scope Eyepieces

For digiscoping, what would be generally preferred, a 30X or a 20x60zoom.

Which would take clearer photos? Would the distance from the subject the issue?

If 50 yards was the normal, farthest distance, which eyepiece but the most suitable?

What is your preferred eyepiece for everyday use?

Regards

Hi

For digiscoping, a fixed power eyepiece with a wide field of view translates into less vignetting because the lens of such an eyepiece is typically larger than the lens of a zoom eyepiece and fixed power eyepieces typically have more eye relief than zoom eyepieces - more eye relief allows for more latitude in positioning the camera over the eyepiece. However, I would recommend less magnification than even 30x, say a 20x or 25x for most of your digiscoping. When you kick in the optical zoom of the camera with a 20x eyepiece, you have plenty of magnification for most shots and you can always crop as needed in your software. The point, here, is that you stand a better chance of getting a sharp pic at a lower magnification (for several reasons), but as long as you have a sharp pic, you have something to edit. A fuzzy pic is a deleted pic.

That said, I have used a good zoom eyepiece (a cheap zoom eyepiece is worthless of digiscoping) when I had no time to change eyepieces, but even a good zoom will typically produce more vignetting and very rarely will you be able to use more than 30x or 40x, anyway.

As for other uses, a zoom is still my favorite, especially for birding or hunting where you often don't have time to change eyepieces before your subject disappears. For more casual uses where time is not so critical, a set of fixed power eyepieces are great and are typically more comfortable to use.

I head out in the field with both types of eyepieces.
