Meade 90mm StarNavigator Refractor DS2090AT-TC

This is my first ever astronomy gear review of my first telescope: the Meade 90mm StarNavigator Refractor (DS2090AT-TC). It has a 90mm aperture objective, 800mm focal length giving it a focal ratio of F/8.8. It is computer-guided which is perfect for beginners.


I think this is a great telescope for a beginner such as myself. It got me hooked into astronomy that now I want to learn more about it.


The mount could be very flimsy. When you’re adjusting for focus, it takes about 5 to 10 seconds for the vibrations to stop. Sometimes the GOTO capability isn’t quite accurate. The focuser is made of plastic that it might not be able to handle the weight of heavier accessories.


I like its simple design and build quality. I like how light it is to transport and how the tray does not need to be disassembled to fold the legs. I like the GOTO capability when it works. It allows a beginner like myself to spend more time observing than looking for objects.

My First Telescope: Meade 90mm Goto Refractor

Meade 90mm Goto Telescope

I bought my first telescope today off Kijiji. It was a Meade 90mm Goto Refractor. I’ve always been a fan of astronomy and I watched a lot of astronomy documentaries, but I had no clue where to begin with telescopes. So I scoured the web for telescope basics, how to choose a telescope, and a few telescope reviews. I concluded that my first telescope would be a refractor, and my original budget was $100 for a used scope. So I went a little over my budget and paid $130 for this one, and it was brand new. Not bad.

The telescope had a 90mm aperture and a dew shield. It came with 5 Meade “MA” eyepieces ranging in focal lengths from 24 mm to 6 mm. The tripod came with a built-in tray that conveniently folded along with the legs without it having to be disassembled first. The computer had a control keypad that connected via a telephone coil.

Setup was simple enough that it only took me 30 mins to set it up. The red dot finder was also easy to setup. As with any new telescope gear, it is a well known fact that there will be clouds on the first night of your purchase. However, tonight, I got lucky.

I set it up in my backyard and went through the initial 2-star alignment. It was supposed to orient itself to the nearest bright star. My problem was that I didn’t know what the names of the stars were. So I was lost. At the end of the setup procedure, I followed the tour, but each object was not in the field of view. And whenever something was in it, I didn’t know if it was the correct object. The only recognizable object would have been Saturn, but it was too low that the houses next door were blocking the view.

I just ended up manually slewing the scope using the controller. I was amazed at how may more stars I could see. I even saw a double star, and a couple of satellites passing through the field of view. Overall, the feeling was good. Somehow, something got triggered inside me to continue along this path of amateur astronomy. More to come.
