Look, we get it. Stating that we’re the “best” can seem a bit like a catch. However, with a combined astronomy experience of over 115 years (117 to be exact), our team of telescope and astrophotography experts, a.k.a. "Gear Experts", knows astronomy and how to service our customers.
We know how to narrow down the products that best fit YOUR needs, rather than push something simply because it’s easy. Once we’ve done that, we ensure you understand WHY we’re recommending the product by teaching you the concepts behind the product and in the process, we demystify all the terminology. Leaving you with confidence knowing you are making the right decision and one that is perfect for you and your goals of viewing the night sky!
Our knowledge is only surpassed by our passion for this wonderful hobby we all love so much. We truly believe our team is a cut above the rest and we look forward working with you!
NON-COMMISSIONED PRODUCT ADVISORS
Our team of product advisors know what it’s like to buy astronomy equipment for the first time. There are so many types of telescopes and accessories that the process can be overwhelming enough without having to worry about pushy salespeople trying to make a big commission.
That’s why our unbiased, non-commissioned product advisors’ only incentive is to recommend a product that they truly believe is the right choice to help you meet your goals, and at a price point that also meets your budget. There’s never any pressure to buy, and you can rest assured that your recommendation is personalized for you rather than motivated by financial gain. We look forward to helping you start your astronomy journey!
Celestron NexStar 90SLT Computerized Telescope
Designed to be an affordable entry-level to mid-level computerized GoTo telescope, the NexStar SLT refractors, reflectors, and Maks are available in the most popular sizes and are loaded with valuable design features. With preassembled, adjustable stainless steel tripods, and quick release fork arms and tubes, NexStar SLT telescopes can be set up in a matter of minutes with no tools required!

Most NexStar SLTs can also be used as a land-based spotting telescope.
Intelligent Design:
Powered by 8 AA (user supplied) batteries or an optional AC adapter (#18778) these NexStar GoTos love to travel. The internal battery compartment provides power to the high precision servo motors for rigid low-vibration performance while eliminating cord wrap issues associated with external battery packs. With the NexStars ergonomically designed hand control, the user is free to remove the hand control from its holder for remote use or leave it cradled for hands-free operation. With a touch of a button you can select the object catalog, change the slew speed, view fascinating information about an object, or simply know if a desired object is visible in the sky.

Astrozap Flexi-Shield Flexible Dew Shield for Cele...
Dew can quickly ruin a night of imaging, but there are ways to keep it at bay on all but the wettest of nights. Wrap this flexible dew shield snuggly around the end of your 90 SLT tube assembly to delay the formation of dew on your telescope's corrector plate. A dew shield also prevents stray light from bouncing off your optics and reducing contrast.

Celestron 40" Telescope Soft Case
Store and transport your Celestron SLT telescope in this soft case with room enough to hold the whole enchilada…telescope OTA, mount & tripod! There are separate areas for each large component, and small accessories can be stored in the external zippered pocket or bonus padded accessory bag! A great investment to keep your telescope dust and ding-free for years to come.

Celestron Car DC Battery Adapter
Power the NexStar SLT off of your car’s battery or a portable power pack with this DC power cable that ends in a Cigarette Lighter Adapter.

Celestron PowerTank Lithium LT
Use this Lithium power supply to power your NexStar SLT mount! This portable device has a USB port to also charge your smartphone or tablet and is perfect for emergency power as well. FAA approved for your carry-on!

Apertura 1.25" Moon Filter
You won't believe how bright the moon is through a telescope! A Moon Filter will dim the light, just like sunglasses do, so you can see more details on the lunar surface. The moon filter threads onto the barrel of all included eyepieces and any other astronomy accessory you buy later that has a 1.25” barrel.

Apertura 2x 1.25" Barlow
A 2X Barlow is one of the most popular telescope accessories available because it doubles the magnification of any 1.25” eyepiece you use with it! This telescope comes with a 25 mm and 9 mm eyepiece, for 50X and 139X magnification, respectively. Double those numbers by adding a Barlow to the mix, and for every eyepiece you buy thereafter, you ‘ll have two magnification options instead of one!

Apertura 15mm Super Wide Angle 1.25" Eyepiece
The Celestron SLT comes with a 25 mm & 9 mm eyepiece that yield 50X and 139X magnification, respectively. If you add this 15 mm eyepiece to your collection, it will magnify by 83X. Add a basic 2X Barlow to the mix and you’ll achieve 278X with the 9 mm eyepiece, 100X with the 25 mm, and 166X with this 15 mm.

Apertura Universal 2 AMP AC Adapter
Your Celestron SLT can run on 8 user-supplied AA household batteries, but you can also plug it into an AC wall outlet with this inexpensive AC adapter. Save your batteries for times when you're observing in remote locations.
