THE INDUSTRY'S BEST TELESCOPE AND ASTROPHOTOGRAPHY EXPERTS
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!
iOptron Photron 150 Ritchey-Chretien Optical Tube
iOptron Photron™ telescopes feature a Ritchey-Chretien optical design that boasts primary and secondary mirrors with low thermal expansion quartz and 96% reflective coatings. The primary mirror is fixed to prevent the image shift encountered with other telescope designs. This Photron RC6 comes with 2" dual-speed Crayford focuser and three focuser extension rings to allow "flex-free" solid extension as a way to eat up any unnecessary back focus. Equipped with an internal multiple knife-edge baffle system, the Photron RC6's steel optical tube enhances contrast by reducing stray light, improving the instrument for use both visually and photographically. A Vixen-style dovetail plate is included with the RC6 model.

iOptron 8x50 Finder Scope with Bracket
This iOptron 8x50 finder matches the 6" RC OTA and comes with a finder bracket. When aligned with the main telescope, this finder will help you find and center objects.

Celestron Padded Soft Case for 9.25" SCT/EdgeHD or...
While this case was created for another scope, it’s 25” length makes it a good choice for the 19” long iOptron RC6 OTA. The zippered heavy-duty soft case will protect your scope during storage or transport. A zipped pouch can store smaller accessories.

Astrozap Flexible Dew Shield with Notches for 6" A...
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 RC tube assembly to delay the formation of dew on your telescope optics.

Apertura 2" Twist Lock Carbon Dielectric Mirror Di...
If you'd like to use this telescope for visual astronomy, you will need a diagonal. This upgraded 2” model slides into the back once the adapter included with the scope is attached and accepts both 2” and 1.25” barreled accessories. Buying a 2” diagonal instead of the standard 1.25” allows you to buy either size eyepiece or Barlow. Some of the best low power eyepieces have 2” barrels, so why not get a diagonal that can accept both?

Apertura Super Wide Angle 10 mm 70° 1.25" ...
This 10 mm Super Wide Angle eyepiece will produce 137X magnification when used in the iOptron RC6. If you also pick up a 2X Barlow, you’d be able to double the magnification of the 10 mm to 274X, for max magnification on nights of good seeing.

Apertura 2x ED Barlow Lens - 2"
A 2X Barlow is one of the most popular telescope accessories available because it doubles the magnification of any eyepiece! Since this is a 2” 2X Barlow with a 1.25” adapter, it will work great with both 1.25” and 2” eyepieces, but does need a 2” diagonal or focuser to accommodate its larger 2” insert barrel. Grow your magnification choices quickly by adding a good 2X Barlow to your accessory case.

Apertura Super Wide Angle 15 mm 70° 1.25" ...
This 15 mm Super Wide Angle eyepiece will produce 91X magnification when used in the iOptron RC6. If you also pick up a 2X Barlow, you’d be able to double the magnification of the 15 mm to 182X, great for the planets on steady nights.

Apertura Plossl 40 mm 45° 1.25" Eyepiece
We are offering this 40 mm eyepiece to allow your telescope to achieve low magnifications. The 40 mm produces 34X when used with the iOptron 6” RC, but if you also pick up a 2X Barlow lens, it will double the magnification of the 40 mm eyepiece to 68X. The 2X Barlow could then be used with any other eyepiece you acquire!
