While you're here, how about checking out the
Astronomy Book
List ? |
Hi,
I am looking for an reticule eye piece that has the ability to measure
angles and distance, plus be used for alignment. Meade has one, the 12mm
MA Astrometric. I have a 9mm MA and do not particularly like the quality,
it seems to be quite a bit away from the 26mm Plossl that came with the
scope. Of course the 9mm MA did come with a rather cheap Meade starter
scope.
Are there recommendations for other brands? If you have the Meade
Astrometric, how does the quality compare to a Plossl? How much eye relief?
What is the field of view ? I am not sure which to ask for the apparent or
actual? The 26mm I think has a 52 degree field of view, I also think it is
"apparent" and if actual depends on the scopes focal length?
One other thing is it just me or do others prefer using a eye piece with a
larger FOV (26mm) and a barlow instead of trying to look through the little
dot of a glass provided by the smaller field of view (9mm) eye piece?
Thanks in advance,
Rick in Tucson
