SXP2 mount with SD103S apochromatic refractor.
This telescope set has everything you need to observe the night sky.
It includes a telescope, a mount with automatic tracking, a tripod and eyepieces.
The SXP2 mount comes with the new STARBOOK TEN control technology and the PFL polar viewfinder, which allows you to configure the mount quickly and easily via reference stars.
The SD103S was optimized for photography and provides a sharp image all the way to the edges.
The telescope set also offers outstanding visual performance and produces sharp and high-contrast images without chromatic aberration.
It also produces impressive images of the moon's craters and Saturn's ring system.
The mount can be operated fully automatically and finds celestial objects automatically.

The SXP 2 mount in detail

Strong mount housing
Compared with previous models, the new SXP2 mount features larger bearings in order to increase the accuracy and load capacity.
The mounting housing is made from a stronger material than the previous SX mounts.
The equatorial head is clamped into a fork in order to increase the stability of the polar alignment wedge.
Precise tracking with P-PEC function
The SXP2 mount comes with the modern STARBOOK TEN control system. This includes a P-PEC function for precise tracking. PEC stands for ''Periodic Error Corrections'' and corrects errors in the mechanics which lead to periodic errors in the gear systems. The P-PEC function, which is based on the PEC function, is designed for the SXP2 equatorial mount. The P-PEC function saves the records of corrections, even after the power supply to the mount has been switched off. It is not necessary to re-enter the data each time, which enables a quicker setup and more precise tracking.
The belt drive system minimizes backlash and noise
Conventional motor-driven systems on equatorial mounts use gear wheels, which are driven by the motor.
However, this design generates backlash under the gear wheels, which can lead to inaccuracies.
To avoid these errors, the drive was converted to a belt drive system. This drastically reduces the backlash of the gear unit, as well as the noise generated by the drive system. It also ensures a quicker reaction when corrections are required.
16 bearings
The mechanical parts contain a total of 16 bearings.
The SXP2 mount uses a set of tapered roller bearings for the RA axis in order to provide additional stability for more precise tracking.
Stable polar alignment wedge
The SXP2 mount uses the same fork as the heavy AXJ mount. This new construction enables a quick and stable configuration of the latitude setting.
Simple and precise polar alignment via reference star
The 6x20 polar finder scope is pre-installed. This allows the user to configure the polar alignment (for both the northern and southern hemispheres). The polar finder scope has a variable illuminated reticle with an automatic power-off function. The brightness can be adjusted in 8 levels so that the user can configure the desired brightness.
The polar finder scope can be configured directly via three reference stars and can reach an accuracy of up to 3 arc minutes.
Variable mount head
The mount head has a diameter of 35 mm and features 8 threaded holes for M8 screws spaced at 45 degrees. An optional accessory tray can be attached to the mount head directly or in combination with an optional mounting wedge for dovetail plates. The threaded holes on the mounting head can also be used to mount rails from other manufacturers.
Modern STAR BOOK TEN controller with high-resolution colour display and built-in star chart
The STAR BOOK TEN controller is a modern control system with a high-resolution colour monitor.
The STAR BOOK TEN system contains more than 272,000 celestial objects, including 260,000 stars from the SAO catalogue, 109 Messier objects, 7840 NGC objects and 5380 IC objects, as well the soon, moon and planets. Objects can be accessed by name, and information such as images and data can be defined separately.
A combination of innovative, elegant design and user-friendly features
The improved design of the stable and rigid mount body, which features precise tracking with a P-PEC function and STAR BOOK TEN control system, offers a highly precise, easy to use mount that is guaranteed to please astrophotographers and observers.
Special motor mount for lighter counterweight
The heavy RA and DEC motor units are built into the bottom of the declination axis to ensure that the centre of gravity of the equatorial head is below the RA and DEC axis. This enables the declination body to function as a counterweight. Thanks to the flat mounting head, the mount can be balanced with a significantly lighter counterweight.
Retractable counterweight bar
The counterweight bar is made from solid stainless steel with a thickness of 20 mm, and enables the use of all counterweights from the SX and GP mount series. The counterweight bar is housed in the declination body.

The SD103S in detail
A new apochromatic refractor with high-performance Super ED glass (=SD).
The FPL53 glass reproduces an extremely clear and sharp image by eliminating residual chromatic aberration.
Another advantage of these SD refractors is their short length and lightweight design.
The SD glass is designed to focus all beams of violet, red, blue, yellow and green light exactly onto the same level.
The special lens material reduces chromatic aberration across all colours.
Together with the new optional SD Reducer HD Kit or SD Flattener HD, these refractors provide illumination with a 44 mm image circle for full-frame SLR cameras.

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.
