SKY AT NIGHT MAGAZINE REVIEW of the Olivon MC-105
Oivon is a popular brand specialising in optical instruments that you may have come across if you've done any bird-watching. However, its increasingly finding that some of its products are also being pointed at the night sky, and so its latest offering is the MC-105 Maksutov-Cassegrain telescope tube. It comes with a 45º erecting prism (1.25-inch fit) and a 7x21straight-through finder, but no eyepieces. A good 26mm eyepiece would be perfect for getting the most out of this telescope, in order to look at the planets and the Moon. Maksutovs like this one are noted for being compact and portable instruments, because their long focal length is folded into a short tube. The long focal length gives good views of detail on the planets and the Moon, as well as deep-sky objects like double and multiple stars.
However, it also means that faint deep-sky objects such as galaxies and some nebulae dont fare quite as well. To aid our review, we used an Olivon photographic tripod, which allowed us to evaluate how useful the telescope was for a quick hit of the night sky. We also fixed the scope to an equatorial mount so that we could track the sky and get longer views of our test objects. Find and seek Our first impression of the finder was confirmed when we looked through it: its small size was adequate for relatively bright objects such as the Moon, the planets and the brightest naked eye stars, but very few of the deep-sky objects we picked for our test were visible in it. The finder was also a bit too close to the upper eyepiece holder, meaning it got in the way slightly when looking through the eyepiece.
The 26mm and 10mm eyepieces supplied for the test gave magnifications of 52.5x and 136.5x. We used the 26mm to gauge the quality of the field of view, pointing the scope at the stars Regulus and Arcturus. The telescope performed well and was very good across almost the entire field of view, with just the last few per cent near the edges showing some minor distortion.
To test the scopes fine resolution we viewed the close double and multiple stars Algieba, Castor and Epsilon Lyra, also known as the Double-Double. Even with the 26mm eyepiece we could see that Algieba was a double star, and using the 10mm eyepiece the golden-coloured stars were clearly separated. Castor is a closer pair and was split using the 10mm eyepiece, while the Double-Double was split into its four components using the 10mm eyepiece a fine sight indeed.
Saturn, though small, was excellent using the 26mm eyepiece, with a crisp disc and sharp edges to the main ring system. We glimpsed the southern belt on the planet and we could clearly see two of its moons, Titan and Rhea. At least two other moons, Tethys and Dione, were just on the edge of visibility. Switching to the 10mm eyepiece, Saturn remained a great sight and the gap in the rings known as the Cassini Division was more evident. Viewing the mountains on the Moon, it was great to see the vivid shadows they cast. We also enjoyed looking at detail in some of the larger nearby craters.
The telescope is clearly capable when dealing with such bright objects and really brings them to life. On the other hand, the long focal length of the telescope is a slight drawback when we turned it to deep space. It was quite easy to see the brighter Messier and NGC objects, but fainter galaxies and nebulae struggled. M27, the Dumbbell Nebula, and M57, the Ring Nebula, were both good at low and high magnifications. But fainter objects such as NGC 6207, a twelfth-magnitude galaxy near M13, suffered a bit. Overall the MC-105 is ideal if you love looking at the planets, but it still has enough power to reveal some of the wonders of deep space.
The supplied 7x21 straight-through finder works reasonably well and it doesnt add significantly to the weight of the tube. Despite its small size, the view was clear and showed just enough stars to point the way to most of our target objects.
The Olivon MC-105 comes with a standard tripod bush to allow it to be attached to most makes of photographic tripod for everyday use. It is also possible to attach
a dovetail bar (not supplied) so that it can be used on an astronomical mount.
A Change Of Scene
The scopes flip mirror is a handy feature. It gives you the standard astronomical view (back to front and upside down) through the top eyepiece holder and,
with the erecting prism, a right-way-up view at the rear of the telescope for pursuits such as bird-watching. However, using both eyepiece holders is useful for astronomy too, because it allows you to switch between magnifications, albeit with a slight shift in the focus. We removed the 45º erecting prism from the rear
of the scope, replacing it with the 26mm eyepiece, and stuck the 10mm eyepiece in the top slot. However, we found that this feature didn't work quite so well when the scope was mounted on an ordinary tripod. The large focal length gives quite high magnifications, so it was easy to nudge an object out of the field of view. That said, we had no such trouble when we mounted the tube on an astronomical mount to track the sky and hold it firmly in place. It was enjoyable to be able to swap between magnifications, allowing us to compare low and high power views with relative ease. Its a useful feature built into this scope.
