I have an 8" F6 Newtonian on a dobsonian base, with 32mm TeleVue, 10mm and 7mm Pentax XW eyepieces. Let me add in that I am >60, and just 18 months into this obsession.
The main reasons for choosing these eyepieces are quality of image, field of view, and eye relief. I considered field of view quite important, to reduce the amount of nudging required to keep an object in view, and eye relief important for comfort and ease of use. I do not like a narrow field of view.
The TeleVue does not match the Pentaxes with edge of field of view 'sea gulls' being quite obvious. It is a very good eyepiece for getting onto a target and gives acceptable wide field views, and is great value for the price. The future will see a similar focal length, wider field of view, high quality replacement.
Pentaxes are absolutely delightful. To my eyes they are just magic, and it is pretty cool to actually be able to 'look around' in the eyepiece to take in the full view. As I move to higher magnification work, introduction of a high quality barlow or another Pentax will be the go.........!
My brief experience has shown that high end eyepieces are absolutely worth having, but there is the cost issue! It is also worth understanding that one tends to grow into observing, and with the experience gained, good decisions can be made about equipment; and with improving equipment, more discovery and subsequent enjoyment results.
