So, I was saving up for my next ideal eyepiece, the Orion Stratus 13mm, due to my fantastic experiences with the 21mm model. But, I caved and found a University Optics 6mm Ortho on www.astromart.com. I tried the eyepiece against some double stars (Eta Cassieopia and Rigel) and it performed nicely, with slightly better contrast than the view offered by my Meade Series 4000 6.4mm Plossl.
