    I absolutely love my Orion ST80 F/5 which I think is similar to your scope. I have it set up on a good camera tripod. The lenses that came with it are decent but if you look at my signature you'll see I have better lenses and that's what I use on it. I use it a lot in winter because of the ease in getting it out and setting it up. I mostly use my Baader 24mm 68° EP in it as I prefer the low power wide views it provides. Once in a while I'll pop in the ES 11mm 82° EP

    Hello fireball61,

    I have an 82mm fast spotting scope, and on the bright galaxies and nebulae it performs best at the magnification of 40x; in your case, this would be an EP f=10mm. The best choice at the middle budget levels is either the Baader classic ortho (f=10mm),or a comparable high-end Plössl (unfortunately the expensive Tele Vue). These EPs transmit a maximum of light and offer the highest contrast.
    Regarding the planets and the Moon, you can go to the magnifications 80x up to 100x with the LE Long Perng eyepieces, which are due to the ED lens elements well corrected against the aberrations, and which offer a very comfortable 20mm eye relief.

    Best,

    JG
