Seben have lots of good inexpensive stuff. The 17mm Superwide Angle eyepiece I got for $34 was pretty good, not quite as good as my old Meade 18mm Superwide, but a fraction of what I originally paid for the Meade. Also, Seben's Flat Field eyepieces seem to be the same as everybody else's who sell them, but they are cheaper from Seben.
If you eventually want to hunt faint stuff like galaxies, it's best to get a nice wide angle or ultra wideangle eyepiece that gives a 2mm exit pupil. If your telescope is f/6, then that equates to a 12mm eyepiece.

Thank you renato for the reply.
I'm not wearing glass
btw.
So is it okay to use 4mm to view details on planetary? If I use barlow with my 10mm ep, that means I will get magnification around 5mm right? That is quite close to the 4mm.
Btw, I normally use my scope to view faint stuff too. So, does it means that wide angle ep will give me a better view?
Urmm..my focal ratio is f/5.9. Is it a good thing? I don't understand much about focal ratio stuff..sorry
PS: What size should I use for a perfect viewing of clusters?
