Celestron TrailSeeker Fluid Pan Tripod

The perfect tripod should be stable yet lightweight and easy to operate, requiring minimal knob twisting and lever flipping. The Celestron TrailSeeker was designed to be your perfect tripod. It is lightweight (3.94 lb.) and compact, yet it can hold up to almost 9 pounds of equipment.

The aluminum legs of the TrailSeeker Tripod are fully adjustable, not just in length, but in their angle as well. With the center column fully extended, the maximum height achieved is 70.5 inches (58 inches with the column down). Each leg is made up of four sections that can be shortened or lengthened with the flip of a simple lever lock. This makes it easy to make the tripod a little taller or a little shorter as your terrain or needs change.

Each leg can also be set to three different angles. If the place you need to set up your tripod is not perfectly flat, the ability to adjust the angle of one or more legs makes all the difference.

The center column of the TrailSeeker tripod does more than just go up and down. The bottom end of the column holds a retractable balance hook. This simple device can make all the difference in the stability of your tripod, especially on windy days. Just hang something heavy from the hook like a backpack and you’ll be amazed at the difference. When the hook is not needed, it retracts up into the center column to stay neatly out of the way.

Two of the legs come with padded wraps, providing protection for your shoulder when carrying and making it a little more comfortable to make adjustments during cold weather. The legs also feature rubber feet to keep them from sliding on slick or wet surfaces.

The Celestron TrailSeeker Tripod is topped with a two-way fluid pan head. The single handle makes it easy to move the head around, and one oversized knob adjusts the tension and locks the head in place. A quick release plate with standard 1/4-20 thread mount makes it easy to attach a spotting scope, binocular, camera, or small telescope to the tripod. The plate snaps into place when inserted into the pan head.

Other features include bubble levels, located on the top of the tripod as well as on the side of the pan head, and a tripod carry case. The case is the perfect place to store your tripod when not in use, and makes it easy to transport via the shoulder strap.

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.
