This kit consists of a control unit and set of drives: direct drive for RA axis and complete set for replacing a standard drive of the DEC axis with a «worm» drive.

In SimpleDream EQ2 there are modes of operation for both the Northern and Southern Hemisphere.

SimpleDreamEQ2 mount control system designed to automate an equatorial mounts of SkyWatcher EQ2, ORION EQ2 and their analogs. SimpleDreamEQ2 compatible with Meade Polaris mounts. It can be used in a «stand-alone mode» or «control mode» (from PC or mobile device).

SimpleDreamEQ2 «Micro GoTo» feature allow to find a space objects automatically, quickly and accurately and follow them with different speeds. With the «Guide» feature you can create astro photos with large exposures. Built-in WiFi access point allow wireless control of the mount from planetary software that works on Windows, Android or iOS.

SimpleDreamEQ2 speed modes:

tracking speeds – «star», «lunar» and «solar»
adjusting/guidance speeds – x10, x30, x60 from solar speed
guiding correction speeds – x0.5, x0.75, x1.0 from stellar speed
guidance speed in «Micro GoTo» mode – x60 from stellar speed
In «Micro GoTo» mode mount control system can work with any astronomy software (Windows OS) that supports ASCOM platform: Stellarium, Cartes de Ciel, StarCalc and others. ASCOM platform and Meade Generic LX200 telescope driver should be installed on the PC first. For the Android and iOS in «Micro GoTo» mode SimpleDreamEQ2 works with SkySafari, OrionStarSeek, and other software. Meade Classic LX200 telescope should be selected.

In «Guide» mode mount control system can work with astrophotography software: MaximDL, Guidemaster, HDGuiding and others. ASCOM platform and GuideDream driver should be installed on the PC first. ST-4 port of the mount control system should be connected to GuideDream and the unit itself (not included in this kit) should be connected to PC with USB cable.

Variety of platforms, drivers and applications with what SimpleDreamEQ2 can work creates a user comfortable conditions depending on the tasks assigned. For example, for astronomy photography laptop or PC is used to search, target and guide the object during exposure. Such options has mostly the Windows software. But for visual astronomy application it will be more comfotrable to control the mount with smartphone or tablet.

For reliable and long-term engine operation, clamping of worm screws to gears must have a slight backlash. In the absence of this backlash, the worm screws will be strongly pressed against the gears which can lead to missing the steps and even engine failure!
After installing the drive on the declination axis, the standard brake screw of this axis must be in the released state during the operation of the mount. Otherwise, the declination axis drive motor may be damaged.

Before turning on please revise User Guide attentively!

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.
