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 200 Ritchey-Chretien Optical Tube
With low thermal expansion quartz primary and secondary mirrors featuring 96% reflectivity coatings, iOptron Photron™ Ritchey-Chretien designed telescopes are the optimal instrument for color as well as monochrome imaging. Results generated from RC telescopes are void of coma, spherical aberration, and chromatic aberration. In order to improve contrast, the Photron RC8's steel optical tube contains 10 knife-edge baffles that diminish the effect of stray light. Any unneeded back focus is eliminated by three included extension rings for a "flex-free" solid extension. The Photron 200 also comes with a linear-bearing dual-speed Crayford focuser and two dovetail plates that enable mount and accessory attachment while providing additional strength.

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.

iOptron 8x50 Finder Scope with Bracket
The iOptron 8x50 straight-thru finder matches your 8" RC and will help you find and center objects. It comes with a finder bracket.

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 15mm Super Wide Angle 1.25" Eyepiece
This 15 mm Super Wide Angle eyepiece will produce 108X magnification when used in the iOptron RC8. If you also pick up a 2X Barlow, you’d be able to double the magnification of the 15 mm to 216X, great for the planets on steady nights.

Apertura 40mm Plossl Eyepiece - 1.25"
We are offering this 40 mm eyepiece to allow your telescope to achieve low magnifications. The 40 mm produces 40X when used with the iOptron 8” RC, but if you also pick up a 2X Barlow lens, it will double the magnification of the 40 mm eyepiece to 80X. The 2X Barlow could then be used with any other eyepiece you acquire!

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.

iOptron Electric Focuser for Ritchey-Chretien OTA
This electric focuser is made for iOptron Ritchey-Chretien telescopes that are mounted on an iOptron computerized mount. It controls the 8” Photron RC dual-speed focuser when operated via the mount’s hand controller. Features includes a stepper motor, 3-speed control, zero backlash, and ASCOM compliance.
