LXD75 SN6- some EPs can't reach focus?Posted By mark suhovecky |
Hey Folks-
I just took delivery of a Meade LXD75 SN6 telescope yesterday. While the astronomer's curse (rain) has kept me from doing any real obeserving with it yet, I've noticed that I can't achieve focus with some of my eyepieces, all Televue: specifically, a 20mm & 40mm Plossl, and a 4.8mm Nagler. My Televue 8-24mm zoom works fine, another 40mm works fine (Scopetronix), as do the rest of the eyepieces in my stable. I've got the focuser racked all the way out, and I'd bet another quarter inch would do it. I dimly recall being told once that Teelvue EPs are parfocal within a series. Very frustrating. Comments or advice are welcome.
Thanks,
Mark
