Subject: Finderscope in the way with highpower eyepiece

First I want to thank you for your great site. It has really help on
some issues I couldn't find the answers to in Meade's manuels. My
problems comes from the rightangle finder scope. When viewing with the
26mm eypiece it is not an issue, but as I move up in power, and the
eyepieces get shorter it does get in the way for a right handed viewer. 
Are there any quick and easy (low-tech) fixes for this problem that you
reccomend?
thanks in advance

Mike here: There are a couple of things: 1) Rotate the finderscope
eyepiece outward away from the eyepiece. I have mine set to about 45
degrees. 2) Don't insert the eyepiece all the into the tube. Actually,
there is a 3rd alternative: use a different finderscope.
 
 
Bruce here:
What I use is the Celestron camera T adapter #93625.  This came with a
Celestron 80mm WA spotting scope package.  It is about 1.5 inches high,
I use this as the extension tube for higher power eyepieces (7, 9,
12.5mm Orthos) and others. I am able to keep the finderscope straight up
this way.  One could use other eyepiece extension tubes like the Orion
#5123.  I have had no problems with this extra height and focusing on
objects.  The T adapter has a set screw also.
