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!
SkyWatcher 8” Quattro Imaging Newtonian
The SkyWatcher Quattro 8 is a fast f/4 Newtonian with extra features that make it a really nice OTA for imaging as well as visual observation.
This 8” SkyWatcher Quattro f4 Imaging Newtonian has an 800 mm focal length. The parabolic mirrors are ground from borosilicate glass and fully multi-coated for bright, sharp images.
Besides the optics, the focuser is one of the most important components of the telescope system, and that is especially true when imaging. The SkyWatcher Quattro 8” comes with a 2” dual speed 10:1 linear power focuser. 10:1 dual speed focus allows you to make larger adjustments to focus in the normal manner, and then use the fine focus knob for smaller tweaks that are so critical to producing a sharp final image.
The SkyWatcher Quattro f4 Imaging Newtonian comes with a straight-through 8 x 50 finder and bracket as well as a tube ring set with a Vixen-style dovetail bar for mounting on a wide variety of equatorial mounts. The Quattro Coma Corrector is available optionally. It will correct for coma around the outer edges of the mirror that are typical of fast Newtonians. This correction is desirable when you want to shoot to the edges of the field for some deep-sky imaging work.
