Meade LS-8ACF overview

  • 1Description

Ushering in a new era for amateur astronomers, the Meade LS-8ACF LightSwitch 8" f/10 Catadioptric GoTo Telescope aligns itself with virtually zero input from the user. The LightSwitch system first obtains the current day/time/location using an onboard GPS module, next the integrated CCD camera takes a series of pictures of the night sky overhead, then it references the relative positions of the objects in those pictures to the AutoStar III database to properly and accurately align itself—all in about 5 minutes. During long-exposure astrophotography, the LightSwitch system acts as an autoguider to monitor the tracking accuracy and correct any errors in real time.

Optically, Meade utilizes their Advanced Coma-Free (ACF) catadioptric light path to reduce color fringing and off-axis comas to enable it to clearly resolve dim deep-sky objects and easily split binary stars with tack-sharp clarity. Complementing the ACF system is their Ultra-High Transmission Coatings (UHTC) system, which improves light transmission through the entire light path across the whole visible spectrum. A combination of high-transmittance lens coatings and highly reflective mirror coatings boost image brightness, while minimizing internal and external light loss and diffraction.

An aluminum single-arm alt-az fork mount carries the optical tube assembly (OTA) and runs on eight user-supplied C-cell batteries for off-the-grid observation sessions, and supporting the entire system is an adjustable-height stainless steel tripod. To get you out and observing immediately, Meade includes a relatively low-power eyepiece, a 90° star diagonal, and a red-dot finderscope. Complementing the large 8" aperture, the diagonal and visual backs are made for 2" eyepieces, accessories, and imaging gear. For observation, 2" eyepieces tend to have longer eye reliefs and wider fields of view, making it more comfortable during long observation sessions. For imaging, the larger back ensures exiting light completely covers larger camera sensors to avoid vignetting.

Ideal for making detailed lunar and planetary observations with the capability of reaching far beyond our solar system or as a powerful astroimaging rig, this user-friendly, completely automatic, fully GoTo-equipped observational platform will reveal the wonders of the universe to new and experienced amateur astronomers alike.

    Meade LS-8ACF reviews

    LS-8ACF LightSwitch 8" f/10 Catadioptric GoTo Telescope is rated 4.0 out of 5 by 15.
    Rated 5 out of 5 by from You need an open sky and your car at som The Meade LS-8 ACF lightswitch telescope performs exactly as advertised. Turn it on and once it thinks a while, it finds the guide stars and works like a charm. However, as mentioned in the manual, the scope needs to see the guide stars, The further apart they are in the sky, the better the accuracy (think about it). But if you set up too close to your car, it does impair the GPS. I don't know if you need a full 50 feet, but it works. You don't need to know the constellations. Note that since it's not an equatorial mount or use a wedge, it's not suitable for long-exposure astrophotography,

    Rated 5 out of 5 by from Easy to use telescope For a beginner, this is a no brainer. This telescope uses its LightSwitch tech to position itself automatically. It eases you into telescopes rather than requiring you to know too much. One thing I do want to point will want to buy a higher powered eye piece which lets you zoom in better. The standard eyepiece is good but I will be buying at least one more for now. Also, you WILL NEED some kind of filter to view the moon. It's way to bright to look at without a filter. So, plan ahead and get the filter (I'm looking into one myself).

    Rated 4 out of 5 by from Good, but with exceptions Overall this is a great telescope for a beginner, provided you are willing to spend a bit of money. The descriptive audio and the self alignment all make this a very user friendly product. On the other hand, if you already know your way around the stars, then the Meade LX-90 series has a more solid mount and a nicer viewfinder scope (and still has the auto alignment.) For people debating between ACF and SC, the ACF is well worth it for photographers and people looking for a relatively undistorted image at the edge of your view.

    Rated 4 out of 5 by from Loving it I really like this telescope. Easy to setup and it self aligns even in my brightly lit neighborhood. I had an ETX-125 before I got the LS-8ACF and the two scopes are really night and day. No more trying to align stars (the LS-8 does it automatically) and it really does pull in a lot more light than the ETX-125, especially in a bright neighborhood like mine. Don't bother using the telescope with C-cell batteries. This thing eats batteries. Get the car power cord or if you are using it near your house, a 100ft power cord and a 12v wall wart. Also, ignore the problem reviews pre-2011. With firmware 1.6a, all the bugs and problems that people were having seem to have been fixed. If you are beginner, the built in commentary is pretty good. It is great for showing friends and family, who are not familiar with astronomy, what they are looking at through the eyepiece. Best of all, you can always turn it off, if it is not your thing. The LS-8 is lighter than a Celestron CPC800, but that lightness comes at a cost. When focusing, there is a long settler time. I have heard that the electronic focuser solves this problem. I can bearly lift a CPC800 and tripod combination, but the Meade LS-8 is a lot lighter. I do not have a problem lifting the LS-8 and tripod combination. The upside, is that I am more likely to take the LS-8 outside to actually use it. Don't get me wrong, the LS-8 is a lot heavier than an ETX-125, but not as heavy as a CPC800. For me, it strikes a really nice balance between telescope size and weight.

    Rated 5 out of 5 by from Great telescope! So easy to use - switch it on and leave it to align for five minutes and it's ready to go. The Autostar computer is easy to use to find what you want to look at and there is a commentary that beginners will find useful (but that you can thankfully switch off!). All in all very user-friendly. It does eat batteries, so I need to get an alternative power source and the moon is way too bright - I should have ordered a filter along with the scope. And I know this is supposed to be a lightweight scope - but it's right at the limit of what I can carry (17 kg) and I won't be carrying it far!

    Rated 5 out of 5 by from Awesome Wow, I was a bit nervous spending the amount of money on something I may only ue every now and then but the first time I saw Saturn all my fears were gone. I have used it every night and day since I got it and my six year old follows me out the door every time I go to set it up. My only fear now is what to do if they make a better one. Just one thing I had to slow down the max slew rate as it had trouble slowing down for some objects. But once done it was fine.

    Rated 5 out of 5 by from Amazing Scope w/ No hassle Flip the switch and it does it all. It levels itself, finds where it is and then will tell you everything in the sky worth looking at. Take pictures with the on board camera and many more pluses!!!

    Rated 5 out of 5 by from Fantastic buy! This is the 4th telescope I have owned. This scope has all of the features you possibly want which makes it a great scope for the amateur to enthusiast! Simple to use. Works great out of the box. I highly recommend this telescope.
