Product Information

Since telescopes require regular adjustment, you’ll want a chair that’s adjustable as well. An astro chair with little to no adjustment capability is about as useful as a fixed telescope! Adjustable chairs are also often collapsible, which is an essential feature if you plan on frequently changing locations. 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 The chair itself is made from steel and is quite sturdy and durable, making it suitable for extended outside use. The chair folds down for easy portability, and it’s an incredibly lightweight design. It supports weights up to 264 lbs, and the wooden legs come with protective foot covers.

If you’re looking for portability at a fair price point, we recommend you look into the Alera Plus IL Folding Stool. It’s an astronomy observation chair that’s easy to fit almost anywhere and easy to set up thanks to its straightforward design.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”.

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. The only difficulty is getting into and out of the seat when it is on the lowest two rungs. Otherwise, it's a tremendous chair.

Any thoughts on quality or suitability of these Catsperch chairs? Any thoughts on a strategy to deal with the wide range of eyepiece heights I'm getting with this scope? Weight limit: up to 250 lb (220 lb is manufacturer recommended limit) 2. Starbound Astronomy Viewing Chair For telescope observing, you will need a good adjustable chair so that you can change the height of your seat, enabling you to adapt to whatever position your telescope happens to be pointed. So, now that you’ve learned of the importance of astronomy observing chairs when it comes to comfortably watching the stars in all of their wonders, you are now ready to take matters into your own hands and use the newly received knowledge in helping you decide which one is the right for you. It mentions a weight limit of 220 lbs, but some users report it being able to hold up to 250 lbs (not recommended though). This chair is a simplistic design, but it works precisely as it’s intended.

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. The unique design doesn’t also make it look different, but it also functions differently. The seat itself is removable, and its position can be changed by inserting the seat into the predefined notches set at different heights. There are 6 of these positions, ranging from a height of 9 inches to 30.7 inches. While using a chair for astronomy isn’t the most labor-intensive, you’ll want something made with durable and resistant materials.You’ll need a chair that doesn’t start falling apart after a few uses outdoors and is resistant to rust or corrosion. It’s lightweight and foldable, though the description is a tad misleading, as it doesn’t fold completely flat (about an extra 4-inch profile when folded).
