355mm (14") f/4.5 Parabolic GOTO Dobsonian

Combining the power of a large optical tube, the portability of the patented collapsible FlexTube design and SynScan computerised Go-To technology. The new Skyliner FlexTube Synscan Dobsonians finds over 42,900 celestial objects and automatically tracks them as they move across the sky.


The patented dual-encoder design allows you to manually move the telescope anytime and to anywhere you wish - with no need for realignment. Slewing to an object on the opposite side of the night sky no longer feels like watching a kettle boil. Simply push the tube close to the object and let the computer do the rest of the work.

14 inch Flex Dobsonian Goto
27 May 2019  | 

I am still newish to this astronomy I have had a 40 years plus away from it all together. started of with I will say middle range 6 inch reflector the sky watcher 150i. this gave me a new and fresh look into the hobby again. just bare in mind this kind of scope is not one I would start with as some body new to astronomy. I soon reallised I needed more light gathering power and to keep the F stop at F4 as near as. I had the aim of getting into deep space objects such as galaxies and clusters lastly nebula the faint left over remains of the gases etc that normaley we cannot see with the human eye this is were the OIII filters come in. so looking around and gathering Information realised I needed a bigger mirror. so I was looking at the 10 inch flex for starters but soon jumped up to the 350p flex am glad I took the plunge every were I point the scope to a object sure enough its there in the view finder. and as a starter I use 38mm pan view lens 2 inch even this wide a field on the 350p flex it shows up the Hercules cluster M13 wow as for away as it is in the eye piece I can see the little individual pin prick stars, were as on my 150i tube it was a blur whitish cloud when I managed to use the most power I had using the 10mm and the barlows x2 and x3 gave me between x320 to x420 I was looking at the inner ring of the cluster it was sharp and spaces between all the stars in the inner cluster. so this just proves its all about gathering enough light and the 350p sure does that. I then change the eye pieces to 25mm then 10mm even using my x2 and x3 barlow lenses it was a unreal breath taking site. you see the images what folk do with astronomy cams and dslr well they tend to over expose the clusters of stars when you see the same through the eye piece its a different view is for the better to the naked eye. and onto the ring nebula m57 in Lyra just increased the lens power from 10mm to adding the x2 barlow and the ring is there in the eye piece it was half filling the eye piece. and so on if you thinking what to get yes its a big outlay but worth it the nights go to fast bad enough i have to wait until 2300 for it to be dark enough to get out in my back yard to star align the 350p up and thats it were of. the only issue I found was because I cannot leave my scope outside I have to strip it down and take it back in the house for storage, so you have the x2 sides and x1 panel that fits between the x2 sides.this is not as bad as you think the worst of stripping it down is the rotating base its very heavy and a little awkward even with the x2 side panels off and the x1 between the 2 side panels off it leaves the base to handle on my own but I manage just take your time. but after that hard work its all worth it when you look through the stock eye pieces that come with the scope you will be taken away with the breathtaking views that will not dissepoint you its got the big punch and it will make your fellow astro friends envy you.

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.
