Have landed a 6mm supermono (1st run) eyepiece on AstroMart just now. Ordered a 12mm for the just announced next run that Markus of APM Telescopes announced on AstroMart a few days ago but I don't expect that one for a while. Having the 6mm by GSSP is important to me. Now to find an 8mm ... someday. 6mm gets me 1.6mm exit pupil and 8 would be a nice complement at 2.16mm (for no paracorr in 18" f/3.7). I realize the 2nd run and beyond have the better baffle but frankly one must jump on what one can find and the 1st run are reported as quite nice as well. I'll upgrade if my outstanding request to APM ever happens for that 6mm (and 8mm).
