After over a month of looking at various telescopes and thinking hard so that I don't foul up the special event that is buying my first telescope, I've finally decided on the Skymax 127 on the AZ-GTI mount.

Just wanting to hear from others who have the 127 (preferably on the az gti mount) and what you think is good about the scope as well as eyepiece recommendations smile.gif

Just about all the 127mm Maks are the same.  I have the Orion version.  Mine rides on a NexStar 6/8se mount, very stable for it.

Focal length is 1500mm.  That makes a 10mm eyepiece produce a pretty high for the aperture 150x, so I wouldn't bother with eyepieces shorter than 10mm.  My "high power" EP for it is my 11mm ES82*.  Usually the 68* 24mm is in the diagonal.

Excellent choice.  I've enjoyed using mine. 30mm, 22mm and 16mm my most used eyepieces with it. I've looked through three of these tubes and they have all been good. Often lives in the back of the car.  The antidote to the size and weight of my C14.

You'll have a great time with this little powerhouse, it is a great little lunar and planetary scope, portability is super also.

Punches above its weight.  I had one and was impressed with the views and the portability.  Mostly a lunar and planetary specialty scope at that FL.  I would still have it if I didn't own the 6" Mak.  I don't see how anyone would be disappointed with it.

It's a great size.

Be sure to get a dewshield for it--it'll fog up easily otherwise.

A few notes:

S&T's test showed this is effectively a 121mm scope.

My own tests showed the focal length was 1540mm with the standard visual back and 1.25" star diagonal.

When I filed off the threaded portion of the visual back, it reduced to 1505mm.

For every 10mm extra rear length, the focal length increases by 35mm.

The quoted 1500mm focal length is a "rounded off" figure.

That made the f/ratio f/12.7 and I reduced it to f/12.4 by shortening the visual back.

From that you can see the main problem is getting a low enough magnification.

I recommend a 32mm Plössl as a low power(48x, exit pupil 2.5mm, true field 1.00°).

If you are like I was over the years I owned the scope, magnifications above 150x won't be used much.

That's a 10mm eyepiece.  You can use a couple in between the 10 and 32mm and a 2X Barlow for when seeing is fantastic.  I occasionally used mine at 323x and 

it did fine on some close double stars, so a Barlow will be useful.

The scope justifies the purchase of a better star diagonal than the stock one.

Use the pier that comes with the mount, sit down to observe, and lower the tripod as much as you can.  Every inch makes the scope more stable.

It isn't a triplet apo refractor, but it's small, easily transported, and not that expensive.

My 5 inch Mak is a lot of fun. The Sky Watcher go-to mount makes it very easy to find many interesting night sky objects. It's really a good all around student scope. Under a dark sky, the 5" aperture shows lunar and planetary detail quite well. Brighter deep sky objects can be breath taking. Better eyepieces improve the views considerably. I use a Explore Scientific ES 30/52 for my wide eyepiece. Either a Baader Mark IV or Celestron 8-24 zoom to examine detail. Good luck with a great choice! waytogo.gif

One thing I really like about this scope is all the positive feedback it gets :) I plan on upgrading the standard 10mm eyepiece to a 10mm plossl as well as getting a 32mm plossl for those larger targets like the beehive,the Pleiades and M42.

YOUR MILEAGE MAY VARY.

I have an update regarding my personal 127mm Mak.  I made a Mak to SCT adapter on my 3D printer and tried it with the 2" SCT diagonal I've been using on my C8.

I'm certain that vignetting is there but my eyes weren't offended by it, when using my current lowest and widest eyepiece, a 40mm 68* by Explore.  Also looked great with my 20 and 30mm 82* eyepieces.

With the 40mm, it fit the Pleiades, and it didn't seem like a waste of time.

It. Fit. The. Pleiades.  That's a BIG target for a Mak.

Suddenly, this telescope is infinitely more useful to me.  I paid for a metal version of the adapter immediately, will retire the plastic one when the metal arrives.

This is an especially interesting development, as I detect noticeable vignetting with my 82* 30mm in my 8" Dob.  Don't know what magic is going on with this Mak, but it can realistically be a go anywhere lightweight go-to scope for me now.
