Yes, there are others. What you want to avoid are the specific models, such as the Nagler 12mm, Type 4 that have a reputation for kidney bean and blackening out at the edge of the field when used in daylight. These are poor choices for daylight work. Remember, Naglers, were designed from the getgo to be astronomy eyepieces, not daytime eyepieces. Some work, some don't, as daytime eyepieces. Right now I do use a 22 mm Nagler for a lot of my digiscoping and daylight work and love it. It would duplicate, though, what you already have with your 24 mm Panoptic. I have used the Radians for day work, though they tend to be a little fussy about eye placement for day work to suit me. You might try some of the shorter focal length Panoptics, assuming they have enough eye relief to suit you. I have also used the Pentax
XWs for day work and highly recommend them all. Great eyepieces, as well.
zooms will work in your scope. I don't rate them on a par with the fixed power Televue eyepieces
, but they aren't bad and will work for most of your daytime needs, though I stay with fixed powers for digiscoping. My first choice, though, in a zoom would probably be the Pentax zoom 70509
. It ranks right up there, in my book, with premium spotting scope
zoom eyepieces. Unfortunately, it is priced like one, too.
