Quality of these EP & Filters?

I was looking at the February issue of Astronomy today and I saw an ad for Astronomics. They are selling Burgess optical Eyepieces (6, 12, 17 and 20mm) that are claimed to have 60 to 67 degree FOV for just $49. What is the quality of these eyepieces?

Also Adorama had a Celestron Oxy III filter for $65 which is a bit cheaper in price that most others I have seen for sale (most are around $99). Has anyone used/reviewed the celestron Oxy III filters?

I have Burgess 32mm 2" and a 6mm TMB form Burgess and for the money I think they are fine when people look in the 32mm they say WOW what type is that a TV ... now I don't think I would go that far But as I said for the money.... an OIII for 65.00 ill have to check that out.

Hi Alfred,
I have independently discovered a broad rule of thumb that many have discovered before me, and that is this: you get what you pay for. There are no really good, really cheap eyepieces out there that provide wide fields of view, long eyerelief, and sharp performance. That doesn't mean that the bargain eyepieces don't have their place, they do! IF your scope is not very demanding of the eyepiece (read: slow focal ratio), or IF you're not bothered overly by less than great edge performance, then these eyepieces may well have a place in your case. If you're using a fast focal ratio scope, and are bothered by less than great edge performance, then kick up the dough, you're ready to go, with the expensive premium eyepiece.
I've also been discovering the same thing concerning filters. The more expensive ones do seem to perform better than the less expensive ones, but whether your eye will be satisfied with the less expensive model, only YOU can tell. Ya just have to buy and try in most cases. That's what makes astronomy something of a journey, and not just a destination, it takes time to find all these things out for yourself!
