second scope - which one? Orion ShortTube 4.5 EQ or SkyQuest XT 4.5

Hello all,

My first scope was a Meade Polaris 114EQ-D purchased at Service
Merchandise a few years back. I want to know purchase a second scope
and even though I would really like to get a 6" Dob, the finances only
allow for the $199 models.
The choices are the Orion ShortTube 4.5 EQ or the Orion SkyQuest XT
4.5. WHich is the better one of these two choices? I like the EZ
Finder scope on the Shorttube but I know that is not a clear reason to
choose one or the other. Does anyone have experience with either of
these models or another brand that would be better to replace my
Meade.

The Meade Polaris gave me great views as a begineer and still are
impressive. If I get either one of these scope, will I have the same
scope that I have now (upgraded the eyepieces to Orion Explorer II's)
or will either one of these blow me away compared to the Meade
Polaris?

I'm just afraid of getting a different version of the same scope and I
know that the 6" dob would be a better scope than these, but yet
again, need to stay at $199.

Any recommendations or comments on these would be appreciated.
Again, any other company scopes that are better than what I have now
for the same price ($199) would be helpful.

Thanks,
Jim Fedina

You can have a 6", or even a 8", dob for $199 if you build it yourself, and
are creative/shop around for parts. Building isn't an option for everyone,
but if you have access to woodworking tools, are reasonably handy, and have
the time then you can build a better scope than you can buy.

Hi Jim,

Not being familiar with these particular scopes, I can't say
anything about their relative performance. What I can however see is
that, looking purely at the numbers, they're all pretty similar. I
wouldn't expect either of the two scopes you picked to give you a
significantly better view than what you have, at least not $200
worth, anyway.

As you mentioned, a 6" dob would be a good step up from your current
scope. If you can't stretch to the price of a new one, you might try
picking one up second hand, for example on Astromart
(http://www.astromart.com/). If you're handy, you may want to try
building your own although, from what I've heard, that doesn't
always turn out any cheaper in the end.

Cheers,

Steve

could you list some example suppliers? all the ones i've found are more
expensive than buying an assembled unit.

thanks.

Jim:

The short tube scopes such as the Orion ST 4.5 EQ you are considering have
significant optical limitations due to the built-in barlow/corrector that makes
the short tube possible. (Note: The 130ST does have a barlow/corrector.)

Anyway, heres the good news...

DBA Astronomy has 6 inch Hardin Optical Deep Space Hunter DOBs for $199.
Shipping is $40 anyway in the US which should be comparable to the Orion
Shipping.

In order to build inexpensively you must be creative and patient. If you
buy new, off-the-shelf parts then you will spend more than buying a whole
scope. Primary mirrors, secondary mirrors, and focusers are regularly found
on Astromart, at star party swap tables, from astro club friends, dealer's
used/surplus stock, etc. You can and will find these items if you have the
time and patience. Eveything else (e.g. plywood, teflon, formica, sonotube)
is widely available.

You can grind, polish and figure your own mirror. My 12 year old son has
made a wonderful 5" f/11.4. However, this takes a lot of time, patience and
determination, and not everyone has as much of these as he does.

There is nothing terribly wrong with the commercial Asian dobs, and there is
a lot to be said for these scopes. However, the mounts don't work as well
as good homemade ones, and many folks find themselves spending time and
money to improve them. Also, building your own scope means that you will
know it inside and out, which is necessary when it comes time to
collimate/clean/upgrade.

Actually in my experience the mounts work OK especially when new. After a
while, I have found things need some help. At some point some Ebony Star and
Teflon will straighten things out.

On a good night, just fooling around with barlows and double stars I have had
my 10 inch F5 up over 1000X. Not so easy but doable... Takes a half decent
mount to do that... and it was stock..

Also, building your own scope means that you will
know it inside and out, which is necessary when it comes time to
collimate/clean/upgrade.

I think one pretty much ends up knowing the scope inside and out whether its a
commercial scope or a home built.

These days its pretty hard to beat a commercial DOB price wise with a
homebuilt, its even pretty hard to beat a new scope with a used scope.

Go Here (below) there is a 6" F8 for $160
Meade Factory Outlet

"http://tinyurl.com/3w4uy"

On AstroMart 6" F5 go for about $100!
then u can spend another $50-$60 to build a fine Dob base.....

I just looked again at the Meade Outlet http://tinyurl.com/3w4uy

And saw they have 7 8" F6 tubes for $215 and remember that all Shipping chardes
