[AZ-Observing] Re: Finderscope

Stan,

Absolutely!!

Meade 80mm ED APO Triplet. $700 comes with enhanced 2"diagonal (scope and
diagonal are compression ring) and case.  Phenomenal views.  Many people
have looked through it and possibly can comment.  Bill Anderson, Ken Sikes,
Paul Knauth, Steve Coe come to mind.  The little scope with the Meade 14mm
UWA is an awesome thing to look through.  24mm and 35mm Panoptic views of
M42 and the Double Cluster are fascinating and beautiful. I bought it to
satisfy several needs, finder, wide field views, photography both
terrestrial and stellar and birding.

I made a ring setup for mine and the tube wall is thick enough to ride right
on the scope.

Here's an image shot with it, scroll down to the comet image:

More images of the scope and through it on this page:

I did away with the "foot type" mounting and made rings, poor picture of the
ring setup and a image of the horse head shot through it on this page:

If you happen to be down at Farnsworth Ranch for the AAMM then you can look
through it.  Reflections in the images are the camera adapter.

The finder scope that comes with the Meade 16" LX200R is a pain in the
neck because it is always going out of pointing alignment and every time
I start a  night I have to re-align it. I am thinking of replacing it
with a 3" refractor to serve as a finder, possibly guider, and for solar
observing, i.e., H-Alpha and all that.

Can anyone suggest a good refractor that would not cost thousands of
dollars and still give good images for solar stuff? For this a
chromatically  corrected objective is not necessary, from my understanding.

I always use a straight through finder because I use both eyes to center
an object. The Meade finder uses a 2" objective and so it doesn't seem
that going to a 3" would obstruct my one eye. I know this depends on how
widely separated a person's eyes are. I imagine David F. could easily
use a 4" refractor as a finder scope. (-:  Does anyone have any
experience using something as large as a 3" for a finder scope?

Finally, I want the pointing alignment to stay put and not continually
change as the Meade one does. Since refractor's are thin tubed (except a
certain model of the TMB refractor) I think I might have to machine two
thick aluminum sleeves, one for each end of the tube, and cement them to
the  tube. I could buy mounting rings, but I probably could machine
something more sturdy that would hold pointing alignment better. Does
anyone have any other suggestions?
Stan
