A telescope optical tube is the body of your telescope.  The Optical Tube Assembly is often shortened to the phrase "OTA".  While most telescope packages offer fully equipped OTAs, there are many circumstances where the optical tube might be all you have.  Perhaps you built your own telescope, bought one in pieces, or you're working on restoring a telescope, or you're just starting from ground up on building your own custom telescope assembly.  No matter what your needs are, OPT has developed this category to help you find the accessories to complete it with ease.  Let's look at what we have to offer.

 

 

Under the Finderscopes and Accessories category, you can find what you're looking for.  Here is where you can learn about the different styles of telescope focusers and what would work best for you and your OTA.  Once you're ready, you're going to be looking for eyepiece holders or visual backs.  We have styles to suit your every need so that you can adapt any visual accessory or camera.  When it comes time to connect, look no further than dovetails, plates, rings, and accessories.  If it can be mounted to the OTA or if the OTA can be mounted to something else, we have what you need to make it happen.  To help balance everything out, OPT also stocks tube weights.  Evening out the distribution of weight makes systems work easier and promotes less wear and tear on gears.  Now let's look through that OTA.

Under the category Binocular Viewers and Accessories, you'll find the equipment to explore the cosmos with both eyes.  We offer the best in binoviewers and the accessories to make them work, plus we explain how they work and what they work best with.  Under the category Diagonals and Accessories, you'll find more information on how a star diagonal works and what type might be right for you and your needs.  When it comes to filters and accessories, nobody does it like OPT.  Look under the category Filters and Accessories where you can learn more about each filter type and their applications.  If you have a Schmidt-Cassegrain OTA, you might want to consider an SCT Cooler.  Made for a variety of models, these systems are made for ventilating the inside of SCTs, Maks, and other catadioptric telescopes so that they may be brought quickly to ambient temperature.  This allows image-ruining tube currents and heat pillars to be minimized in 10-20 minutes instead of the usual 45 minutes to 2 hours.  By evening out the greater temperature difference between the place your telescope is stored and the outside evening air, the more quality viewing time you can reclaim.  

Perhaps imaging is what you have in mind for your OTA.  If the thought of focal reducers, flatteners, and extenders has you confused, you won't be for long.  This category tells you all about the products we have to offer and what they're used for.  If you're interested in doing astronomy photography, then you might want to check out Guidescopes and Accessories. Mounted on your OTA, this equipment helps keep you lined up.  Maybe your needs include guiders, rotators, and accessories.  At OPT, you'll find autoguiders, reverse cables, field rotators, off-axis guiders, radial guiders, mounts, camera rotators, and more.  

Once you're set to go, you're going to be interested in protecting your prize OTA.  No matter what size or model you have, we carry telescope cases to protect your investment.  From model specific to dimension specific, OPT has you covered.  We offer every dew solution imaginable and we've assembled everything you need to stay high and dry, including finderscopes, eyepieces, corrector plates, shields, and more.  When you need help with maintenance, we're here for you.  Telescope cleaning and collimation is an essential part of every OTA.  Here at OPT, we carry the supplies to make the job easier.  Of course, there are always a few Miscellaneous OTA Accessories that don't quite fit specific categories.  Here you'll find touch-up paint, mounting blocks, adapters, mounting plates, flop stoppers, balancing aids, and more.
