RE: [atm_free] Re: should I build a telescope?
Thanks for the reply! Since I posted my question I have decided that I WILL build a scope. Once I started fantasizing about building my own, the thought of buying something off the shelf just seemed boring! I’ll end up spending more, but I know I will understand the equipment much better and it will really be my own. Who knows, maybe I can even make a better scope than I could buy from Orion et al.
I’m looking at the standard dobsonian plans from the San Fransisco Sidewalk Astronomers, though I want to compare them to other plans that may be out there. (Any suggestions?)
Also, does anyone know how primary mirrors from Coulter Optical (http://www.e-scopes.cc/) or Anttlers (http://www.geckooptical.com/anttlers_optics/telescope_acc_atm.html) compare to the quality of the off-the-shelf Chinese scopes? I’m trying to decide if I would be satisfied with one of these less expensive mirrors or if I should wait until I can afford more of a premium mirror. I’ve also had the thought that maybe I should just go with a 12 inch mirror, but I don’t want to get carried away by aperture fever!

Hi Jim -
you can put together a scope that's about the same quality as
one of the imports with a kit. I think e-scopes (you can
google it) has a kit for 10 inch. You'd have to buy a tube
(aluminum or sonotube), build a tube box, rocker box, ground
board, etc. After finishing the wood, cutting and drilling, you'd
probably spend anywhere between 700-1200 total depending
on what you have around the house, what you can get for
cheap (have any relatives with shops and access to wood?),
and what kind of 'look' you want.
Also, there are some individuals on A-mart who are selling
unfinished wood dob kits for a reasonable amount.
I've built a couple of dobs and after all was said and done,
I probably spent THREE times as much as a standard Orion or Meade
of the same size.
Is it worth it? When I'm sitting in my office thinking of the
costs and looking at the price of a 16 inch Lightbridge,
I wonder. But when I'm at a dark site, examining the faint
spiral arms of M101, or catching glimpse of a festoon
in Jupiter's belt, yeah, it's worth it.

is they really go into the thought of the telescope. Not just, how
big and how much it will cost, etc, but
how big are you willing to go and still use it OFTEN? where will you
put it, how will you move it around, do you like ladders or no, do
you want to have a grab and go, or something with more aperature, who
will be using the scope, and where, will you need to fit it in a car,
if its too big you wont use it so you have to do some soul searching
on how big you want to go there, etc.
