About Celestron Maksutov-Cassegrain Telescopes


Celestron's Maksutov-Cassegrain telescopes are similar to Schmidt-Cassegrain models in regards to ease, durability, versatility, and minimal maintenance, but trade smaller fields of view for better resolution in planetary observation.


The Maksutov-Cassegrain is similar to the Schmidt-Cassegrain with essentially the same advantages and disadvantages. It uses a thick meniscus correcting lens with a strong curvature and a secondary mirror that is usually an aluminized spot on the corrector. The Maksutov secondary mirror is typically smaller than the Schmidt's which gives it slightly better resolution for planetary observing.


Advantages of Maksutov-Cassegrain Compared to Schmidt-Cassegrain

 

  • Smaller secondary obstruction results in a slight increase in planetary detail and contrast
  • Less expensive to manufacture
  • Longer focal lengths resulting in higher magnifications for planetary viewing


Disdvantages of Maksutov-Cassegrain Compared to Schmidt-Cassegrain

 

  • Slightly heavier because of the thick meniscus correcting lens
  • Increased time to reach thermal stability in larger apertures over 90 mm
  • Longer focal lengths resulting in smaller field of view

    Well I had a Celestron 90mm Mak-Cass and really liked it but wanted alittle more aperture. I was looking at Orions 127 Apex but when I seen I could basically get the same thing but with also a goto mount I was all in. This scope has really impressed me for the size of it. Mak-Cass scopes are known to be great planetary and solar system scopes and this one is no different. not only has it given great solar system views but also it does very well on DSO given its size. The scope is quick to set up and is very light. The only thing I can really complain about it the lighter weight tripod. When you focus the scope it takes a few seconds before it stops shaking and the image is stable. But for the price of the goto mount it is to be expected. But this scope would make a nice spotting scope, travel scope, or just an all around general use scope. If your looking for nice entry level goto mount/scope this is one to consider for sure.

    Overall, the optical tube assembly (OTA) is a nice performer. The single arm Alt/Az "goto" mount shakes during focusing and therefore takes a little bit of time to dampen out. Focusing is an exercise in patience. I will be using my 127 primarily on a sturdier equatorial mount.

    Tightening the OTA to the Alt/Az arm is also an exercise in patience. Whomever designed this feature failed in my opinion. There is very little clearance to manipulate your fingers and get a good grip on the tightening knob. Low marks here. I may make a modification to mine to enable tightening with a socket wrench.

    The goto function was fairly easy to perform since I'm already pretty familiar with Orion and Meade goto scopes.

    First night out(first light) I got to see a shadow transit by IO on Jupiter, and a nearly full moon (I observed along the remaining terminator for some great shadows) My selection of eyepeices I already have means I didn't put the Celestron eyepieces to use except just once during first light - I popped the 9mm in to see how some moon craters looked...typical for a stock eyepiece. Seeing wasn't the greatest anyway.

    I also viewed the sun a couple of times after affixing an Orion 5.81" glass solar filter to the front of the scope. Pretty nice.

    Overall I give it three stars because I like the OTA. I would recommend the OTA to a friend...The mount leaves a lot to be desired. Since this is my first single-arm Alt/Az mount I'm glad I have experience with other more sturdy mounts so I'm not put off by the experience of the wobblies during focusing.

      Comments about Celestron NexStar 127 SLT Computerized Telescope:

      I've owned this telescope for about 6 months now & I am very satisfied with the overall performance.
      This telescope offers great plantary views such as Jupiter & the four moons and many of the Messiers such as Andromeda Galaxy & Orion Nebula.
      The computerized hand control functions take some time to learn but once I did, I was able to use the telescope quite well.
      The fork mount release to take the tube off for travel is very easy & the motors are fairly quiet and steady.
      There are penty of settings in the hand control to calibrate the GoTo motor, change settings depending on what I wish to view, tracking speeds, the ability to save location settings and many other settings that will make your Mak work the way you want.
      I did notice that the motors seem to run slightly sluggish on fully charged batteries so I try to use my A/C wall adapter at all times.
      The included 25mm & 9mm eyepieces are okay but I've upgraded to the Celestron Omni series eyepieces and the views are crisp & clear.
      I did connect to my computer & downloaded updates & firmware for the hand control software & Alt-Azi motor updates, making the telescope perform much better.
      The tripod can be a bit shaky when windy but calms down very fast.
      I would suggest that when setup outside with windy conditions, place some type of counterweight on the accessory tray as a stiff wind could easily tip the telescope over. I use a 10 pound coated mini barbell even when the wind is calm and the telescope seems much more studier as well.
      I've also used this telescope for daytime landscape views, very impressed with looking across the Bay or Lake St. Clair.
      I also purchased the Celestron NexImage 5 camera which performs great with this telescope.
      I've been able to capture videos then stack the frames in PIPP & Registax 6 for awesome images of Jupiter, superb closeups of the Moon and daytime wildlife.
      I am very satisfied with the Celestron 127 SLT & look forward to buying more accessories to enhance my views & the performance.

        Comments about Celestron NexStar 127 SLT Computerized Telescope:

        Very satisfied with this purchase. A good all around scope. portable enough to take along or just set up in the back yard. The AC adapter is a must for the latter. Get ready for hours of enjoyment with this scope. Setup is easy & the alignment options cater to just about anyone. focusing is a little jumpy & takes a few seconds to level out. acclimation time is about normal for a Mak/Cass. Tracking is spot on IF you follow the instructions for the type of aligment you choose, the planets are easily viewable as are some of the larger nebulas along with pulsars Comets & larger asteroids. satellite tracking is pretty easy too once you get famiiliar with the controls & slew speeds. Delivery was prompt even for ordering on a holiday weekend. No complaints about this scope. It's a big universe & this scope allows you to explore it & not spend the Earth doing it.

          Comments about Celestron NexStar 127 SLT Computerized Telescope:

          First off I was expecting slightly more magnification .then realized that this tube has a f12 focal ratio. Kind of odd for a mak Cass. But with the faster focal ratio than expected it gives a wider field of view than other maks I have seen. The plus side to this is it makes a far better dso scope than originally anticipated. I was able to get the entire double cluster in my field of view. images are sharp and crisp. The mount is quite shaky but easy to get use to. my only real gripe is that the words on the hand controller jumble up and it makes it hard to read .I don't know if this is a common thing or not but it can be annoying. other than.the controller and the shake this is a great scope for the price.
