Maximize Your Observing or Astrophotography with the Right Accessories
Whether you’re dealing with dew, elongated stars, or want to adjust your setup, we’re here to help you get the most out of your gear.
The right accessory can simplify your equipment and minimize frustration by addressing common challenges faced by astrophotographers and visual observers.
For instance, electronic focusers can enhance your telescope’s functionality, while coma correctors tackle optical issues. Others can help streamline or automate your setup.
Discover our range of accessories, and how they can help you get the most out of your gear.
Telescope Accessories


Boost your telescope’s performance with a variety of useful accessories. From filters to finder scopes, we've got everything you need to make your telescope work even better! One quick upgrade to get more out of your telescope is installing an electronic focuser.
Electronic focusers allow you to achieve optimal focus without physically adjusting the telescope’s focusing knobs. The main advantage is the ability to fine-tune your focus with precision, crucial for capturing the sharpest images.
Want to see or photograph more of the night sky? Reducers can help. For instance, using a 0.7x reducer on a telescope with a 750mm focal length reduces its focal length to 525mm. Many reducers also correct for field curvature and coma, delivering sharp stars from edge to edge.
If you own a telescope with mirrors, a collimation device helps with aligning the optical elements of your telescope.
Mount Accessories


Boost the stability and performance of your telescope mount with our selection of mount accessories.
Equatorial wedges assist in aligning your telescope with the Earth's axis, enhancing tracking accuracy for long-exposure astrophotography. To minimize unwanted vibrations and disturbances during long exposures, try vibration suppression tools.
Whether you need saddles, adapters, hand controllers, or electronic components, we have everything to optimize your setup.
These accessories help secure your telescope and ensure smoother, more stable tracking.
Imaging Accessories


Whether you’re a beginner or experienced astrophotographer, having the right imaging accessories can make a world of difference to your photos. Take control of your astrophotography sessions each night with a multi-functional smart controller. Smart controllers have built-in polar alignment aids, image sequencing, and more!
Keep your optics dew-free with our range of dew prevention tools, including dew shields and heaters. From correctors and reducers to adapters, spacers, and power supplies, you’ll find what you need to take your astrophotography to the next level.
Visual Accessories


Explore our essential visual accessories, including finder scopes, dovetails, tube rings, and adapters, all designed to connect optical components like eyepieces to your telescope effortlessly. Want to enhance your stargazing experience? A Barlow lens can double or even triple your telescope's magnification, extending the focal length for a closer view! Diagonal mirrors and prisms ensure comfortable viewing by redirecting light to a more convenient angle.
More Accessories


In addition to telescopes, mounts, and essential visual accessories, Agena has a range of other tools and resources, including power supplies and cables, to keep your equipment running smoothly. Replacement parts to ensure your setup is always in top condition and cleaning supplies.
If you want to learn more about the universe, our range of books, maps, and guides offer invaluable insights into the night sky.
