But not how Celestron ever made it! I assembled a G5 telescope with a half dozen improvements:
1 - The original mount only serves to keep the telescope off the ground. Wobbles if you look at it, damping time measured in minutes. I upgraded to a Orion SVD. Big improvement! (Orion sells them for $240)
2 - Celestron wants you to hold the OTA in 2 hands and then use another hand to screw it into 1/4-20 threaded bolts! I added dovetail adapter from Ken's rings-and-things and a longer Celestron dovetail bar. Now you can actually assemble the scope in the dark without fear of dropping it. (Hardware alone cost over $90, then there was the custom machining)
3 - The original 8X20 finder is a joke - and a bad joke at that. I upgraded to a 8X30. (A $35 value)
4 - The cheap prism diagonal was junk. I upgraded to a Celestron/Vixen mirror diagonal. (Another $35 value)
5 - Contrary to popular myth, you do have to collimate a SCT. Not as often as a Newt, but you do. I added Bob's Nobs to make this very safe and easy. ($17 from Bob)
6 - I found one of the old, hard dew/glare shields. Much better than the new flexible ones IMHO. (No idea of the value, I spent about $25)
Plus, there is the standard 25mm Plossl eyepiece. Finally, the optics are quite good. The planetary views are as good as with my TV85 and I've found most of the Messier objects with this scope.
Even if you start with the spotting scope and build this system, it will cost you around $1050. I’m asking $650 OBO plus S&H from San Francisco.
Wife says that I have too many scopes. Personally, I don't see how that's possible, but I did agree to try and sell this one. Thanks.
