I agree that the number depends on the scope. I have a set per scope, plus some "jollies"..
- 16" f4: 30 APM (jolly), 24 Pan, 12.5 Docter, 8 Delos, 6 Delos, VIP barlow typically set to 1.82x and used with Delos
- 4" Tak: 30 APM, Zeiss zoom (these two use 2" barrel and are used on
DSOs); 9 Nagler, 5 ortho, 3.4-2
HR (planets and double stars)
- TV-60: 24 Pan, 9 Nagler, 3.4
HR, 2.4
HR (jolly)
- 12" f6: 30 APM, Zeiss zoom +/- VIP barlow
I am considering to replace the 5 ortho with a 5 Nagler. Although the ortho works very well, it is too short ergonomically. I need to be careful not to hit my face with the corner of my 2" diagonal.. With my 1.25" TV everbrite diagonal, it is even worse, because my nose hits the diagonal screw, which is installed to the right, and I observe with my left eye.
For these reasons, I've been pondering about a 5mm Delite too. Although this would work well, I don't particularly fancy its super tall appearance, compared to the Nagler and the HRs.. In addition, the larger
AFOV of the 5mm Nagler means that this eyepiece could also be used as a jolly with the 16" f4. It would also fit in the TV-60 bag if I want a "
DSO-only" set (24P, 9N, 5N) with that telescope. On the other hand, the quality of the Delites is reported to match the Delos and this eyepiece would mainly used with the Tak.. :Think: :Think:
You see, this is an example of why people have a lot of eyepieces....! Rumination over rumination about what the best is for your equipment! :flame:
