Product Description

Product Description

When it comes to telescopes, bigger is better, and you can do no better than the Apex 127 compact Mak-Cass. Its 127mm (5")-diameter optics collects 55% more light through its multi-coated, 5" meniscus lens than that of a 4" scope, putting it in the big leagues for astronomical observing and advanced nature study. But big doesn't mean bulky! Even with a focal length of 1540mm (f/12.1), the Maksutov-Cassegrain optical design reduces the tube length to just 15"! The Apex 127 couples to any sturdy equatorial mount or photo-style tripod. T-threads on the eyepiece adapter also allow attachment of a 35mm camera body (with T-ring sold separately). The classy Apex 127 comes standard with a 6x26 achromatic finder scope, a 45-deg correct-image prism diagonal, and fully padded case. One-year limited warranty.

This is an excellent catadioptric telescope with fine build quality and great optical performance.

The package is very light, easy to adjust the finder scope and simple to carry around and set up - fun for the whole family !

I've had a 3.5" refractor but this one is a fine improvement from it and provides great views and good clarity.

I have owned and reviewed all of Orion's Apex line of Maksutov-Cassegrain scopes: the 90mm, 102mm, and now the 127mm. All of them have similar virtues: solid, all-metal construction, great optics, smooth mechanical function with no focus shift that I've been able to detect, and very nice fit and finish. In short, they look, feel, and perform like top-of-the-line telescopes. I've used them in daytime and at night, photographed birds, mammals, distant landscapes, planets, and the Moon with them, and flown with them in my carry-on luggage.

The Apex 127 is a sizable scope. The tube is 14.5 inches long and weighs 8.6 lbs without the finder, diagonal, or eyepiece. Eight-point-six pounds might not sound like much, but cradling that much telescope in one hand while I tighten the bolt on the mount with the other hand is enough to give me the heebie-jeebies, and I always breathe easier once the scope is solidly on the mount. Speaking of mounts, I see that the Apex 127 is often sold together with the Paragon-Plus XHD tripod. Some people may find that works for them, but I am very skeptical of that pairing. The problem is that the weight of the scope will tend to overbalance it if is mounted from below. I have mine side-mounted on an Orion Versa-Go II, and even then it had some teething problems. I originally had it bottom-mounted using an L-bracket adapter, but it would get out of balance at high angles, so I took off the L-bracket and went for a straight side mount. Now it's perfectly balanced and works like a dream; I can go from horizon to zenith with no balance problems and without moving my head more than a few inches.

The plus side of the size is that 5 inches is a fair amount of light grasp, and for a "small" telescope the Apex 127 turns in impressive views of celestial objects.

I like this telescope. It's quite sturdy and compact. It's made well and using it my first night out was very simple. The supplied eyepiece gives a good resolution of Jupiter, you can see individual bands and moons with out difficulty. All in all, its a very fine little telescope. The EQ2 mount that you might consider getting in addition to this is not so great. I'd look for a different mount, but as far as the telescope goes it works fine.

This scope is a good one. I've had a 3.5" refractor but this one is a fine improvement from it and provides great views and good clarity. Have only used the supplied 25mm eyepiece but it works well for all around viewing. Am pleased with the scope and it is well made.

I recommend you to read the review from "black thumb".

As a beginner I would add:

Great beginner solution for Solar System observation: Moon, Sun, Jupiter, Mars, Saturn.

Great beginner solution for Solar System astrophotography.

Not an ideal solution for deep sky observation (you need to go bigger plus auto guider). But you can still photograph the big Messier objects with honest enough result.

Expectations? If you expect to see as detailed pictures as the Hubble telescope provides, either buy a Hubble telescope picture book or roam flicker or other photo sites where advanced photo amateurs publish their incredible (!) work.

For astrophotography you need a tracking mount.

Either you go with an expensive GoTo mount plus an auto guider or you go with an intermediate EQ mount plus a dual-axis motor drive. The former will allow you to perform several hours exposures, the latter up to 30/40 seconds exposures (direct light)(*) or several minutes (camera piggy-backing on the telescope). But then again you're a beginner, a full GoTo+auto guider would be like spending the $$$ for a V12 engine to install on your Bettle or Mini.

(*) For one frame image. It is much better to go with video (dedicated astro cam or DSLR in video mode) whose frame you then stack. This allows you to takes hundreds or thousands of frame for great results. So books recommendations below for more information.

All in all, an intermediate EQ mount plus a dual-axis motor drive is my recommended solution for beginners. It gives you the opportunity to learn the ropes, the constellations, how to hop from object to object. Starting directly with a GoTo makes you miss all these elementary skills.

I bought this primarily for terrestrial viewing. The eyepiece(25mm)included with scope was a bit too powerful for this purpose. I then orderd a 40mm and 32mm and they work great. Also ordered a 20mm eyepice and moon filter for moon/star viewing. Overall very pleased with product and Orion customer support.
