Re: [APML] A Fresh Lens Recommendation Thread
Yes he has...I love that guy<g>
But those ccd pics impress me much...no developing, no extreme amount of
time sitting at the eyepiece freezing my butt off while my lids water and
freeze...that to me is an awesome thing :)
I just got back from taking a look at astromart though and an ST8E is not
cheap<$3100 used> plus all the other unknown things of ccd I dont know
about....ill wait for awhile till they come down to a few hundred bucks when
im old.
Its just all to expensive right now.
Im gettin more lazy as the days go bye.
