Orion XT8 Classic vs XT8 Intelliscope

Hello all,
This is my first post to the group as I am new to the hobby - although
I have had a lifelong interest in Astronomy and Cosmology. I am
considering my first scope and have settled on the Orion XT8 - or, at
least an 8" Dobsonian (I've don't a LOT of reading here and elsewhere,
and the postings here have been invaluable).
My question is this: is there any reason to pay the extra money to get
the Intelliscope over the Classic assuming that I am not interested in
using the positioning electronics that the XT8-IS accept. Even without
the goto module, the IS is $120 than the Classic. If that $120 is
buying me higher quality, important features, etc., then I'll consider
it. But if the only meaningful difference is the electronics, then I
see no reason not to get the XT8-C intead. I am intersted in learning
the sky and it seems to me that the best way to do that is with a map
and manuala approach.
Am I missing something?
Thanks
Ken Sargent
A friend or ours has the XT8 without electronics, and he is very happy with
it and I have enjoyed the views as well. We have relatively dark skies
(pushing mag. 6) and so have no problem seeing enough stars to find
anything. I wouldn't pay anything for the electronics, as I don't want them
and they would detract from my/our style of observing, where finding the
object is at least as important as observing it. I helped my friend rebuild
the bearings with teflon and Ebony Star, and I think we both think that a 2"
focuser would be an improvement for low-power widefield viewing with 2"
nebula filters. The primary mirror is good, but not great.
I would like to recommend building a basic dob with a great mirror.
Building a dob is a basic woodworking project, easily doable with hand
tools. A decent homemade dob will ergonomically out-perform an XT8, and a
top-quality mirror will provide better views. You will not save any money,
and in fact you can spend quite a bit more if you buy top-notch parts
(focuser, secondary, spider, primary) - better parts than those found on an
XT8. However, you will understand your scope inside and out, and you will
never have to ask how to collimate it, or be frustrated by some lack in its
performance, etc.
