The LX200 Series 16" ACF™ Telescope features a 16" aperture, 4064mm focal length, and f/10 focal ratio with Dual-Fork Mounting. Equipped with Ultra High Transmission Coatings (UHTC™) and a resolving power of 0.285 arc-seconds for the improvement of brighter star clusters, more fine detail in nebulae, and greater surface features on planets. Includes a Series 4000 26mm Super Plössl eyepiece (156x), viewfinder (8x50 optical with crosshair), 1.25” Diagonal Mirror, and Super Giant Field Tripod. OTA Dimensions: 17.5” ø x 33” L. Assembled Telescope Weight: 225 lbs. Tripod Weight: 88 lbs. Tripod Dimensions: 30” to 44”” variable.

The LX200 features AutoStar® II computer system with 145,000 object-library, multiple guided tours, High Precision Pointing capability with sub arc-minute pointing accuracy, and Meade SmartDrive with Permanent Periodic Error Correction.

Precise and quick star alignment is done near effortlessly with Meade's level north technology alignment system incorporating a 16-channel GPS receiver. Drive base of the telescope has multiple input/output ports including an RS-232 PC interface and jacks for a CCD Autoguider (user-supplied) and illuminated reticle.

Mechanically loaded as well, all LX200 models feature a primary mirror locking mechanism, which effectively prevents movement of the primary mirror during long-exposure astrophotography or observing. Turn the lock knob located just above the telescopes main focus knob and the progressive-tension primary lock completely cancels any residual image shift due to mirror movement during visual, photographic, or imaging applications.

All LX200 ACF™ models feature the DC-servo driven, super heavy-duty dual-fork mount - the strongest and most rigid mount in its class. Fast slew speeds are from 1 to 8-degrees per second, and can be user selected at 0.1-degree per second increments, while fine slewing and photographic guiding speeds can be adjusted from .01x to 1x sidereal in one one-hundredth increments. Mount and electronics are internally powered by 8 C-cell. The mount also has mechanical locks and slow motion manual controls in both axis if no power is available.

Meade’s LX200 is the most widely used, research-grade telescope system. And now, you can have one too.

Zygo Interferometer Testing For ED Refractor Telescopes!

We are extremely pleased to announce our Zygo Interferometer is now installed and ready for use! Our experienced staff can test refractor lenses up to 120mm aperture and provide a comprehensive 2 page report showing the optical quality and Strehl ratio, plus much more information. We are using the very latest Zygo MX software to provide a more detailed report compared to other standard reports.

 

The interferometer is essentially a measuring instrument. Within the interferometer is a calibrated laser that is pointed through the optical test surface, then onto a high quality reference sphere, then back through the test subject then to an internal camera which gives us the measurement on the screen. From this, we can adjust the position of the test optic and the reference sphere to obtain a perfectly calibrated system. The more central the laser to the test optic and then on return, the better and more accurate reading and measurement we can take. This takes a lot of adjustment to get the best results from the optical surface. Once the measurement has been taken, we are provided with a series of results that show the optical quality of the surface plus other information. Continue reading for an explanation of the individual values and you can also see a test report that was done on one of our RVO Horizon 60 OTAs. 

We are offering certain telescopes with a Zygo test at an extra cost. Mainly ED doublets and triplets. All available telescopes with a Zygo test report are listed here. Just select Zygo Test Report from the drop down box at the top of the listing and we will test the optics in house and provide a full 2 page report with your scope. This will show you the optical quality of your telescope optics. We can also offer this service on your refractor telescope. Please get in touch for more details about this. 

At Rother Valley Optics, one thing we pride ourselves on is customer service and quality of our equipment. When we test your telescope, we will ensure that it is of the highest quality otherwise, we will reject the scope under our strict quality control and test another model for your peace of mind. One of the main values to look at when testing a refractor is the Strehl ratio. The higher this number, the higher quality lens you have. At Rother Valley Optics, we will guarantee the highest possible Strehl ratio for your telescope.  We will aim to provide 0.95 Strehl or higher on Takahashi, RVO Horizon, William Optics and many more! Generally, the higher the Strehl ratio, the lower the Astigmatism and Coma meaning a better image quality from your instrument. 

Other measurements such as the PV and RMS are important too. With these measurements, the lower the number the better as it shows less curvature on the lens. The flatter an optical lens, the better it will perform. The PV rating (Peak To Valley) is a measurement from the highest point (Peak) to the lowest point (Valley). From this we get the RMS (Root, Mean, Square). This is a similar figure to the PV and measured exactly the same way. The RMS is basically an average height difference from the PV so again, the lower the better. As you can see form the example below, we measured an RMS of just 0.027 wave which is a very good value.

We also measure the Power with our systems which is essentially the error from the reference sphere to the test optic. The reference sphere we use on our system is a very high quality sphere so the closer to zero the Power, the less error between the 2 elements thus ensuring a higher quality optical surface. 

You will also see some more values such as Astigmatism and Coma. Again, these are measured by the interferometer when we take measurements of the optical surface after adjustment. These are values which ideally would be at 0 but as our test optics are all curved lenses, there will always be astigmatism and coma present. The lower the number, the less of these aberations you will effectively see but with most refractors, you can buy field flatteners which will compensate for the coma anyway. The astigmatisms value is explaining the error between the symmetrical curvature of the lens. Basically, no lens will be perfectly symmetrical, the lower the astigmatism, the more symmetrical the lens surface is. 

Once the Zygo test report has been completed, the optical alignment is thoroughly tested and tuned to ensure they are spot on before they leave us. 

All available telescopes are on the website at the link below and ones we've tested already that are available straight away are also listed.

Here is an example of the test what we provide. This was a test on one of our Horizon 60 ED OTA's.
