I do not know what scope doyou have but, again, think about it before you buy it. I use the chair when my DOB is at 45-60 deg. I'd only need the full height of the chair when looking straight up BUT, There are plenty of chairs on the market now that are specifically designed for extended stargazing. But which one’s are the best? Does getting an observing chair really matter? Or can you just use a regular chair? We’ll answer all of these questions and more in this guide covering everything you need to know about astro observation chairs! We Recommend

The Starbound Viewing Chair has the most comfortable seat on this list, but this seat comes close (even though it looks thin). The bottom of the chair has a footrest for its higher ranges, allowing you to maintain your correct posture even at its top height of 34”. b) my scope gets in the way so I'd have to lean forward too much when observing "high up". So it became uncomfortable and hence it's easier for meto observe just standing on my feet (when the scope is pointing up)It has a splayed design on both ends of the feet, making it extremely stable for a variety of environments. The chair’s also entirely foldable and portable with a 4” profile, though, at 22 lbs, it is a bit heavy to lug around.

While the material is durable and capable of withstanding most weather situations, the cushioning itself is fairly thin and not the most comfortable. Durable materials are another crucial aspect, as you’ll want something that doesn’t fall apart after a few uses, and can withstand extended periods in cold or warm temperatures. Overall, it’s worth it to get yourself a comfortable chair made or observers. Astro chair needs to be easily adjustable

When it comes to designing and building your own binoscope or binocular telescope, you generally start with several ideas in mind before you actually settle on one. Sometimes it takes a while to really decide which idea or design you want to go with. It becomes almost confusing sometimes when you look at recent astronomy magazine or book on telescope making and see so many excellent examples of homemade telescopes, Dobsonian or otherwise. Trying to decide which design, type, or style of telescope or binoscope you want to build really comes down to the amount of resources you have available plus the amount of spare time you can afford to spend building it. Resources as I like to call it can have two or three meanings: one is how much money are you able to invest in building it and the tools you have available that will be needed to build it with, and last but not least, how much desire and enthusiasm do you have to start and actually finish your telescope building project. All of these are important resources and you have to weigh each with an equal amount of importance before you start your telescope building project. Once you start your telescope or binoscope building project, you don’t want to stop its progress because of something you hadn’t planned for earlier. Once you have decided on a particular binoscope or binocular telescope design, then comes the fun part, getting started on it. Keywords Another advantage of that chair design is that it can be turned around and used as a stool with railings for shorter people, with the seat in the lowest positions. The easiest way to spot a truly ergonomic chair is how it looks. Some ergonomic chairs look like modified office chairs, but the most posture-efficient chairs often look a little odd, with extra padding in specific locations for additional support or other interesting design choices. Your observing chair needs to be comfortable Ergonomic” is basically just a fancy way of saying efficient. Ergonomic chairs focus on the natural position of your spine, enforcing proper posture and, ultimately, comfort. They also allow you to sit much longer without needing to get up and move around.

While it is a little on the heavier side thanks to its solid metal construction, it still folds to a very compact size. Thanks to its vinyl seat, you can be sure that it will be fairly comfortable to sit on and easy to clean due to its slippery texture. 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. The Omegon Astro is yet another excellent astronomy observation chair and thus it has deserved the second best place in our article. It offers a very good seat adjustment range going from 11.8 to 34.25 inches and using most telescopes out there comfortably won’t be an issue.

To prepare the chair for storage or transport, you just have to remove the seat and fold its two main parts together. The only thing that you should be aware of is the weight capacity. Since we couldn’t receive an official rating from the manufacturer, we can’t recommend this particular chair if you have a few extra pounds on you. Adjustable chairs should be easily mobile and compact with a flat or near-flat profile, so it’s easy to lug around. They need a broad range of motion, so you can remain seated at a variety of heights. 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.
