Meade ETX90 Observer with Carrying Case

The ETX90 Observer with Carrying Case by Meade:

Meade's ETX90, 90 mm (3.54-Inch) aperture Maksutov-Cassegrain Telescope is the latest in a long line of Meade Telescopes of the highest quality that have provided novice astronomers with quality, value, and performance for generations. Each model in that series has brought new enhancements and improvements, and this continuation of that legacy is a prime example of that continued quality and efficiency.

Starting your astronomy journey with the ETX90 is an excellent choice. Take advantage of the 90 mm (3.54-inches) of aperture to enjoy close-up views of the solar system and celestial objects anytime, anywhere. Packing your ETX90 Observer and tripod at a moment's notice is a breeze with the carrying case and durable tripod bag. The ETX90 Observer is a sophisticated, heavily automated and highly portable telescope setup that is ideal for a novice or anyone else on the move frequently who wants to engage in visual astronomy. The OTA is removable from the setup, and the setup as a whole includes exceptional features like AudioStar, GoTo technology, and large 30,000 object database. It's a perfect scope to accompany you during camping, hiking, and outdoor activities! Exploring and night-sky stargazing is made fun, easy and educational. With the ETX90, you'll see planets, stars, galaxies, and nebulae at the push of a button!

The Maksutov-Cassegrain optical design of the ETX90 naturally lends itself to pinpoint star images and extraordinary contrast, making it a great deep sky performer and ideal for detailed lunar and planetary observation at high magnifications. meanwhile, Meade's UHTC optical coatings grant maximum light transmission, ensuring the brightest images and the highest contrast. It has a flip mirror included to let light focus to the rear of the telescope (instead of the mirror reflecting the light 90-degrees to the eyepiece), allowing attachment of a camera on the back of the scope (adapters not included). The ETX90 Observer comes with a bubble Level/Compass to make sure your tripod and mount are level. Furthermore, the ETX90 includes a portable but extremely stable full-size steel tripod, and comes with an equatorial tilt plate, allowing for polar alignment which is critical for long exposure astrophotography. It also includes a hard carry case for the mount/optical tube and accessories, and a tripod bag for the tripod.

Spider webs??

The blue carrying case was full of what seemed to be tiny spider webs. Not a huge deal but we were weirded out by it. Other than that we are mostly content with the telescope, although, as newbies we were ready to be stunned by the images and that didn’t really happen. I know at this price point I shouldn’t really expect to be wow’d. The automatic finder is awesome though.

Smooth Transaction Ultra fast shipping.

Just getting back into astronomy after a few years. Good scope, tracks good with proper alignment. Everything arrived in great condition. OPT is #1 in my book. Thanks again.

Meade ETX90 Observer, lightweight and portable

I bought the ETX90 Observer so I would have a scope that was easy to handle. This year I'm 76 and my existing mount and scopes are just too heavy — I wanted something manageable and I saw the sale price on the ETX90 and thought why not? My older gear I had to take outside one heavy piece at a time and it took me an hour or so to get it all assembled and aligned and running. The ETX90 I can carry it out all assembled, almost ready to observe. Two minutes later, after aligning the mount I'm observing, less than five minutes from wanting to observe to observing — it's great! And the VERY nice Meade ETX90 Maksutov has exquisite optics, Venus at 150x is gorgeous, a very nice sharp crescent. M42 is also a treat, the trapezium easily seen as a collection of pinpoint stars. I truly hated to not give The Meade ETX90 Observer 5 stars, it really deserves 5 stars, but for the red dot finder. I could not align it with the OTA, it simply would not adjust far enough in one direction. The RDF was the worst component of the entire system. I put in an order for a new RDF (I do like them) and a few days later I installed and had it aligned a few minutes later and that night it saw first light and I was happily observing. But even with the RDF problem I would still buy the Meade ETX90 Observer again, the system is just too good to let a little thing like the cheap RDF squelch the deal! Very highly recommended!

Excellent Service

I am very satisfied with my recent purchase of a Meade ETX-90. OPT was fast on the delivery and everything arrived as described. I was especially happy with the payment plan that was offered through OPT. It allowed me to purchase a higher quality telescope. In fact, that's a main reason I choose OPT.
