If desired, the 6SE can also be controlled over WiFi with the Celestron SkyPortal app or SkySafari Pro using the aftermarket Celestron SkyPortal WiFi adapter, emulating the Astro Fi and NexStar Evolution telescopes. Apart from the need for external power, a WiFi-equipped 6SE will work more or less identically to the Evolution at a much lower price, as the 6SE’s mount is already plenty stable and well-designed for the task of holding the C6 XLT optical tube. What can you see with the Celestron NexStar 6SE? I found a beginning astrophotography YouTube video by Trevor Jones that had some solid tips and the 2 biggest contributors to my progress was getting a 60MM refractor (Zenithstar 61) and pairing it with a good equatorial mount. I selected the Skywatcher HEQ5 Pro because it had enough capacity to handle my 6SE. The Celestron NexStar 6SE telescope features a Schmidt-Cassegrain optical system, which has a 1500mm focal length coupled with a f/10 focal ratio. Boasting Celestron's StarBright XLT optical coating, you're guaranteed to get beautifully clear visuals, making observing celestial objects an absolute joy. 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.

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. I was amazed by how bright and sharp this all appeared and this is all despite being in a City and a heavily polluted sky. NexStar+ Database 40,000 objects, 200 user defined programmable objects. Enhanced information on over 200 objectsIn the 1970s, Celestrons Schmidt-Cassegrain telescopes brought the hobby of astronomy to the masses and established Celestron as the worlds premier telescope maker. Our founder, Tom Johnson, invented Celestrons proprietary method of producing Schmidt corrector plates for superior views and maximum portability. Johnson believed in creating high-quality optical instruments at an affordable price, and inspired a generation of amateur astronomers. Alignment Procedures SkyAlign, 1-Star Align, 2-Star Align, Auto 2-Star Align, Solar System Align, EQ North / EQ South Alignment (EQ align requires an equatorial wedge)

Here's how it went for me. Maybe there are some lessons there for you to learn and avoid the mistakes I've made. Though pricey, the Celestron NexStar 6SE is well worth the money. It is one of the best telescopes for amateur astronomers looking to take their hobby to the next level. Where to buy? With a computerized scope, each time you start a new observation, you need to enter your current local time, the date, and your location.

The other issues that were less commonly reported had to do with software glitches or firmware problems. So this would cause the controller and the mount not to communicate properly, leading to frustrating situations where nothing worked quite right. The reason for this is simply a byproduct of having such a technology-heavy piece of equipment. Along with the motorized Alt-Az mount is also a field tripod with 1.75” legs. This is easily sturdy enough to hold the weight of the mount and optical tube without much influence from the wind or other vibrations. Collimation is hard for a first scope, as I described above, I modified the OTA so I un-collimated a bit in the process, I bought a laser collimation device, with some improvement, but never got good collimation until I knew about tri-bahtinov masks. Buy one ASAP.

The Celestron NexStar 6SE is an excellent telescope for observing virtually anything in the night sky. Once you’ve leveled it, aligned it, focused it, and got to know its GoTo system the Celestron NexStar 6SE delivers hit after hit. The red dot finderscope is an excellent addition because if you ever want to use this telescope manually without the assistance of the computerized stuff, the finder scope is going to be a valuable tool. It is tough to line this telescope up without the aid of something like the red dot finderscope. The traditional way of finding and identifying objects in the sky is with a printed hand-held star chart. 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. My train of thought was to use the 6SE OTA and build from there, and well it was logical after buying a mount. The AVX is cheaply made as well, the circuit is bad welded and components inside are bad assembled, I have opened the mount several times to make it better or make it work, now these days is working like a champ after many bad nights, wasted the best nights of the year struggling with it.

At 1500mm focal length, the 6SE also tends to have a much wider field of view than its larger siblings, and is therefore more flexible and comfortable for viewing. Generally, Schmidt-Cassegrains are best suited for planetary viewing, but this relatively mid-range focal length allows for wider views of large deep sky objects.
