Default HELP!

Not an expert by any means, but I think the scope you're referring to is the
Meade ETX-125. I got mine (don't even ask how!) about a month ago. When I
ordered it (none in stock), I was told it could take up to 6 weeks to get one. I
got it in 7 days.

Anyway, so far, so good. I've only been using it with the supplied 26mm eyepiece
but I received the Meade special offer eyepieces this afternoon so tonight I'll
be giving the scope a real workout. I live in a very light-polluted area so my
only two targets of interest so far have been the moon and mars. The view of the
full moon was breathtaking! Mars is also fantastic (get a #23A red filter).

The scope is easily portable and sets up quickly. I'm totally pleased with it.

BlankHi, all you experts out there,

I am new to astronomy and I am thinking of buying a telescope. There is one
portable telescope that someone recommended me. It's a Meade
Maksutov-Cassegrain 127mm F 15 (1900mm). Can anyone advise whether this is a
good scope for beginners? Can I take reasonably good photos with it?

Thanks a million!

Cheers,

F15 is a narrow view instrument and Meade is a poor company. You'd do better
with a Celestron and more aperature.

I was also told by an experienced astronomer that, given the large
obstruction (approx 39%), it becomes, in effect, a 3.5" rather than a 5"
reflector. That being the case, how much would it affect the quality of the
images?

I believe that the central obstruction will decrease the
light-gathering capacity of the scope, but not its maximum
resolution. So, in principle, the view might be only as *bright* as a
that through an unobstructed 3.9" aperture (the figure of 3.5" would
correspond to a 50% obstruction, not 39%, and remember that
Newtonians aren't completely unobstructed, either!) but its
*sharpness* would remain comparable to that from any other 5" design.


The obstruction does reduce the light gathering ability and also the
contrast of the image. In effect the reduction in contrast *may*
provide some reduction in maximum resolution, but I doubt most would
noticeit.
