Was thinking:
1. Dso workhorse: Ethos 13mm. Approx 100x. Shud be nearly 2mm exit pupil, huge fov and clear.
2. Dso medium power. Not sure maybe a Meade, tele vue or nagler 6-10mm aiming for 120-200x.
3. Very wide field view - 2" ep, prob a panoptic or explore scientific. 24-30mm aiming for 50xish. Will get a uhc neb filter too.
4. Planets was going to use my Barlow initially, maybe a Pentax xv if cheap....don't think it's a good one do good ones make much of a diff?
Prob going to be super expensive but a 100degree view for the ethos sounds ridiculous!!!
Have I got eyepiece fever for a beginner?? :/ thoughts on the variety of eps??

Yes, I recommend eyepieces that yield 50x, 100x, 150x, 200x and 250x.
That encompasses about 99% of what you'll want to view and if you need higher powers, a 2X barlow will do.
50x--large star clusters, large nebulae, nice star fields
100x--best acuity, workhorse eyepiece for most objects except planets and planetary nebulae and larger galaxies
150x--high power where seeing is unlikely to interfere. Good for small objects like planets, planetary nebulae, small globular clusters and small galaxies
200x--double stars, planets, Moon, small bright planetary nebulae
250x--double stars, planets, Moon, small bright planetary nebulae when seeing is really good.
So that's focal lengths of 24mm+/-2mm, 12mm+/-2mm, 8mm+/-1mm, 6mm +/-0.5mm, and 4.8mm+/-0.25mm
If you have a 2" focuser, then:
24x82° 2"
All the rest 1.25" with apparent fields from 60° (budget) to 100° (no budget).
If you don't have a 2" focuser, then the low power eyepiece becomes a 24mm 68° eyepiece.
I won't recommend brands, because I'm sure you'll get a lot of specific recommendations.
