I was wondering what everyone is using to view the planets with there Z's, I seen a tmb 6mm with 15-20 eye relief thought that was a good choice,, maybe something stronger like a 4 or 5 mm

For my eyes, anything much beyond 200x magnification tends to blur details. With a focal length of 1500 mm, a 5 mm would put you at 300x (telescope focal length / eyepiece focal length = magnification).

Over time, I've downsized to two 2" eyepieces and a 2" barlow. I have the original 30 mm eyepiece the telescope came with, a 16 mm Konig eyepiece that I absolutely love from Gary Russel at Russel Optics, and the Zhumell 2x 2" barlow. With an effective 8mm eyepiece, I get 187.5x magnification, which has proven to be more than enough for me in a 2 inch eyepiece.

I have a Celestron XCel 1.25 inch 5 mm eyepiece, but it doesn't provide planetary or lunar views that are as good as my barlowed two inch 16 mm Konig from Russel Optics.

I have to agree, that much beyond the 166X that you get with the stock 9mm eyepiece, I just don't see too much. I recently picked up the Zhumell 2" barlow, and I love it. I wish I had ordered it with the scope like I had originally thought. I hardly ever use the 9mm any more. I get 100X with the stock 10mm barlowed and that gives beautiful views. After reading the post from sdtopensied, I am now looking at a 2" Konig eyepiece from Russell in something like 13mm, then I will probably be set. Thanks for the tip.
