Eyepiece Kit Advice

[pvaz]

I need advice on my EP kit.

I decided to drop the barlow cause I always notice a slight loss of brightness and detail. Not much but enough to make me want to buy a full set of 6/7 Eps and drop the barlow indefinitely.

I have the DSO kit pretty much done with the following:

Agena SWA 32mm, 20mm and 15mm.

I may add the 26mm and even a 10mm ones since I'm happy with them, they are cheap and I read some good reviews on them. They look exactly the same as Orion Q70 series.

That said, I still need advice on my planetary kit. I'm thinking about getting 2 or 3 EPs. A 6mm, a 4mm and maybe a 9mm.

I found a review that rates the University Optics Orthos above some high end (€) EPs when it comes to planetary observation.

Anyone haves UO Orthos and what's your opinion? Have you ever compared them to other planetary EPs on sharpness and detail? (I know the FOV is very tight.)
