I've used this beast as a temporary backyard observatory while building my permanent one, and it has withstood all weather conditions in my area. Ultra spacious and easy to set up. Out in the open, at our dark site, it has provided protection during the night from strong winds and during the day as well with the roof canopy. I would highly recommend this kit !

The Octans tent is very spacious with room for two large mounts and telescopes along with a computer desk. It is made of a thicker material than a standard tent and has a built-in floor with no holes or places for bugs or water to get in.
The content is very easy to set up and all of it folds down into a 4 foot long bag that comes with it.
I highly recommend this for astronomical uses when you can’t build a permanent observatory

I have been in the market for a portable observatory for almost 2 years, at the local astronomy clubs I got to see some of the ones purchased and the quality was just not present. This product leaves all the others in its wake, seriously a different level of product and I am impressed, it got to 41c today and was amazed how well the silver reflects the heat. Well done team and congratulations on being a world leader from Australia in both quality and price point.

The Phoenix observatory came in three boxes. First box contained the tent, the second box contained the mat, and the third box contained the light/wind shield. I am very impressed with the excellent engineering that went into the design and the manufacturing of the tent. The tent material is thick and made of high-quality that should stand up to use for years. The tent mat is very thick and durable. The light/wind shield is well thought out, easy to use, and does effectively block neighbors outdoor flood lights. All the components are very well made. The color-coded aluminum poles and fabric are of good quality, the screw tent pegs are a great idea and much easier than using stakes and a hammer, and the quick connect “s” carabiner connectors make it easy to connect the tent to the ground mat. The individual nicely made zipper bags, to store each of the individual components separately, is a great idea. The instructional video on how to set up the tent is very informative and really helped in setting up the observatory tent. My 5-inch refractor telescope with equatorial mount, on a field tripod, fits nicely in the tent with room to walk around the telescope and tripod. Since the tent has been set up, it has been subjected to 40 miles per hour wind gusts and was not affected in any way. I am very pleased with my purchase of the Phoenix Observatory tent, it is well made and very sturdy, and I enjoy using it. I would recommend it to anyone who wants a portable observatory.

Have a Question? We Have Answers
How long does it take to set up the portable observatory?
The observatory can be set up in about 20 minutes by a single person, depending on conditions and experience.
What is the difference between the Octans and the Phoenix?
The Octans is our largest portable observatory, while the Phoenix offers a slightly more compact option. For detailed dimensions and specifications please visit the appropriate product page.
Can I fit the observatory in a standard car?
Absolutely. When packed down, the observatory fits into a compact bag that easily fits in most small car trunks.
Is the ground mat necessary, and what are its benefits?
While not required, the Heavy Duty Ground Mat offers added protection from rough terrain and moisture, helping extend the life of your Starpoint observatory.
How can I secure the observatory on windy nights?
The observatory comes with glow-in-the-dark screw pegs and durable guy ropes with tensioners for easy and secure setup, even in windy conditions.
Is the Observatory waterproof?
While our observatory isn't fully waterproof, the walls are made from a tough, resilient fabric that’s highly water-resistant. Crafted from polyester fibres coated with polyurethane (PU), this material offers strong protection against rain and moisture in typical conditions. Designed as a portable observatory, not a permanent structure, they provide durable defence for outdoor use when you need it most.
Are replacement parts available?
Yes, replacement parts for poles, pegs, and guy ropes are available for purchase through our observatory parts page
Why Others Love Us
For years. I was looking at astronomy tents and dyi semi or permanent solutions for my observing. We all know the problems with wind , rain , lights and the sun not just for the telescope but for the gear too.
Enter the octans.
This thing is a beast , a high quality build to last piece of gear.
Along with a Nikon HW 12.5 and my Glater colimattion tools this is
the best buy i’ve ever made for my hobby and prise wise only a bit
north of the Nikon ( at least for Europe ).
Excellent customer support from both Starpoint and Widescreen in
UK.
Glad the Octans has made your list of best buys, we hope that you get many years of enjoyment, and clear skies!
The Octans lives up to its claims. I've found it to cancel both 20 mph winds and neighborhood lights - making observing much more productive. It's very well built too, featuring high quality materials and craftsmanship.
Got this as a temporary shed and it works perfectly for my needs
