Premium 2" epPosted By Randy Roy |
Tom,
I have the 16" Starmaster and use the Paracorr for an effective F4.9. The 26 Nagler is the best eyepiece I've used in the scope (balancing best eye relief for the largest FOV for my eyes for my scope's focal ratio). The 31 is magnificent, but from a dark site I frequent, I was able to view the Horsehead recently with the 26mm Nagler, but not the 31mm Nagler. I believe the difference was primarily the more favorable exit pupil of the 26mm with my scope as well as the increase contrast due to the slightly shorter focal length. BTW, I was able to see it with the 22 Nagler, 24 Panoptic and 17 Nagler. I sold the 31mm and kept the rest. Had my scope been an F6 or greater instead, I have no doubt the 31mm would be a killer ep.
It sure would be great if you could do some comparisons before committing funds.
