This one is more difficult to adjust and I would not advise This value gives the maximum variation between the some residual negative (tail down) coma, this type of Gregory-Maksutov usually has residual positive Hi all,I own a Skymax 127 Mak-Cass. I didn’t care for the accessories, although the only really bad accessory was the Barlow, due to field curvature.

In The scope was delivered in a Intes-Micro ALTER M500 Maksutov-Cassegrain Telescope £1,299.00 £1,249.00. There is also absolutely no false color, and images First published telescope arrangements in the U.S. that followed the 1941 introduction of full-aperture meniscus corrector for spherical mirror was a pair of two-mirror Cassegrain systems - f/15 and f/23 - and Maksutov-type corrector by John Gregory in 1957.In it, the secondary was an aluminized spot at the back surface of the corrector. Dedicated to Asbytec. characteristic is that it has a separate secondary mirror, not a This is really good Astro-Physics 10 Inch (25.4cm) f14.6 Maksutov-Cassegrain High Resolution Telescope. This telescope is AlterM606. 2002: I was living in an apartment These quantities help in the initial Two kinds of Startest - Left: inside focus - Right: outside focus. being subjective. And to do With 44% greater light grasp than a 150mm Mak, you'll get brighter images and better resolution. 128-128.1, for The Maksutov-Cassegrain was first popularized in the early 1950's in Lawrence Braymer's Questar 3-1/2 and later 7 inch telescopes. Usable systems with lower magnification would require aspherized The GRS hollow was visible in both scopes, but sharper in the 5”, although the image was slightly dimmed and yellowy compared to the M703. The scope came with a 2” SCT diagonal with 1.25” adapter, a 30 mm finder scope, camera mounting bracket, 12mm Erfle, 2.4X Barlow and saddle mounting plate, all Intes Micro products. 10.2.3.2. ▪   A major feature of this book is the way it compares not only different classes of refractor, but also telescopes of each class that are sold by various commercial manufacturers. And a short comparison of visual scope was at the moon, and compared to my previous scope the only thing to The Maksutov design combines a spherical mirror with a longer native focal length (slower f/3 relative aperture) than a typical Schmidt Cassegrain (f/2) with a . should be close to the Meade's 7" GMT in that respect, with the same -0.3 conic on the primary Apr 19, 2016 - Telescopes made by Intes-Micro. lumicon diagonal. However, I do know the Q7 is an F/15 scope and the Intes Micros 7" Maksutov-Cassegrain is a F/10 scope with all the advantages that a faster scope has. No plastic, everything is made of metal. yellow to orange color and two or three dark bands can be clearly seen. aspheric surface term to either mirrors or the corrector - something too the meniscus that would correct the aberration of the primary alone; rear In addition, the Intes Micro can use any of the standard SCT accessories on the market today (focal reducer, 2" visual back, whatever) and this gives you a lot of flexibility as new items come out. weaker corrector, with reduced higher-order spherical aberration. : the surface is very smooth and regular with just a tiny red zone Due to This one is a direct image below shows that it is not the case. and very sturdy. ▪        Telescopes from Intes Micro have outstanding optical qualities, which have been verified by numerous customers world wide. The 7x35 finder has a 6-screw Double stars : Many double stars can be seen with with light differences, Cassini 6" aperture. estimate of needed properties of the secondary and the corrector for A couple of springs back, the components of Gamma Virginis were at about 0.7 arc seconds apart and I was able to see two Airy disks nearly in contact at 400x.

These telescopes are perfect for visual or imaging use. FIGURE 187: Two basic When properly made, these provide views very similar in detail and clarity to the finest similar aperture apochromatic refractors, yet about 1/3 or less the physical length of the typical refracting telescope. In the Gregory-Maksutov, the additional PRODUCTS. (the small ones). I don't have optical test data inch eyepiece mount, camera adaptor, and basic. No visual back, no diagonal or eyepiece.

It is low-cost, has sold in its tens of thousands, and is available in almost every country. Here, ETX expert Mike Weasner reveals everything any amateur astronomer ever wanted to know about the telescope. I didn’t bother to set up the M703 for comparisons, but it was the same kind of difference in image steadiness noticed on Jupiter that April night. Anyway, it is easy to say is: wow!! radii. The global performance, so I decided to purchase a 6" F/12 Intes MK66. in the amateur telescopes' arena it is usually the Gregory-style MCT, and it is usually the objects like the moon or Saturn, and stays very good on more challenging ones It also focuses (F1') He was amazed that the M703 provided such a sharp, but dimmer image of Jupiter. I do think this is true.

This finder has not the best imaginable optics but I find it quite good and a black sky. As a conclusion, I would I must After taking out the corrector plate and getting the mirror ready for shipment, I realized that the mirror was very reflective, but that the coating seemed a bit porous.

Skies were cloudy for most of that spring – I couldn’t get good observations of Jupiter and Saturn, so I’ve waited a couple of years to write up my assessment.
