The Vixen Co-60E Cometron is a 60mm achromatic refractor telescope that offers impressive performance for observing various celestial objects. This telescope's Optical Tube Assembly (OTA) is designed with a high-quality, fully multi-coated lens system, which minimizes light loss and enhances the clarity and brightness of the images. The lens has a focal length of 900mm, providing a focal ratio of f/15.1 and a relatively long effective focal length of 1516mm, making it an excellent choice for viewing faint objects such as comets, planets, and double stars.
The telescope's 2.4-inch (60mm) aperture gathers a substantial amount of light, allowing for more detailed observations compared to smaller refractor telescopes. The lightweight and compact design of the OTA makes it an ideal choice for observers who prefer portable equipment. It features a 1.25-inch (32mm) diagonal mirror that converts the image orientation to a more comfortable view for the user.
The Vixen Co-60E Cometron's rugged and durable construction includes a black anodized aluminum tube, making it both weather-resistant and aesthetically pleasing. The telescope comes with a 25mm eyepiece, which provides a magnification of 36x and a wide field of view, allowing for easy location and tracking of objects. The telescope also includes a 10mm eyepiece, offering a higher magnification of 90x for more detailed views.
The Vixen Co-60E Cometron comes with a Vixen Dovetail mounting bar, allowing easy attachment to various mounts and tripods. The telescope's focus is adjusted with a smooth, reliable, and precise 1.25-inch Crayford-style focuser. Additionally, the telescope includes a finderscope mount and a finderscope bracket, making it easy to locate and center celestial objects for observation.
Overall, the Vixen Co-60E Cometron 2.4 f/15.1 achromatic refractor telescope is an excellent option for observers who are looking for a portable, yet high-performance telescope for viewing a wide range of celestial objects. Its fully multi-coated lens system, long focal length, and 60mm aperture provide clear, bright, and detailed images, making it an ideal choice for those who are serious about their astronomical pursuits.
The Vixen Co-60E Cometron 2.4 f/15.1 achromatic refractor telescope OTA (Optical Tube Assembly) is a popular choice among amateur astronomers due to its compact size, good optical quality, and affordable price. Here are some pros and cons of buying this telescope:
Pros:1. Compact and Portable: With a length of only 38.5 cm (15.2 inches) and a weight of just 1.8 kg (3.97 lbs), this telescope is highly portable and easy to transport.
2. Good Optical Quality: The telescope features a high-quality 60 mm (2.4 inches) objective lens made of ED (Extra-low Dispersion) glass, which provides excellent image quality with high contrast and low chromatic aberration.
3. Wide Field of View: The telescope's f/15.1 focal ratio and 60 mm objective lens provide a wide field of view, making it an excellent choice for observing large areas of the night sky such as star clusters, nebulae, and galaxies.
4. Easy to Use: The telescope comes with a 90-degree star diagonal and a 20 mm eyepiece, which makes it easy to set up and start observing right away.
5. Affordable: The Vixen Co-60E Cometron is an affordable telescope, making it a great choice for beginners or those on a budget.
Cons:1. Limited Magnification: The 20 mm eyepiece provides a relatively low magnification of 30x, which may not be sufficient for observing finer details of planets, galaxies, or other deep-sky objects.
2. Longer Exposure Times: The telescope's long focal length and relatively low magnification require longer exposure times for deep-sky imaging, which may result in more image noise and lower image quality.
3. Limited Accessories: The telescope does not come with a finderscope, which may make it more difficult to accurately locate objects in the night sky.
Conclusion:The Vixen Co-60E Cometron 2.4 f/15.1 achromatic refractor telescope OTA is an excellent choice for those who are looking for a portable, easy-to-use, and affordable telescope with good optical quality for observing wide areas of the night sky. However, its limited magnification and longer exposure times may not be suitable for those who are interested in observing finer details of planets, galaxies, or other deep-sky objects.
Recommendation:If you are a beginner or an experienced astronomer looking for a portable and affordable telescope for observing wide areas of the night sky, the Vixen Co-60E Cometron 2.4 f/15.1 achromatic refractor telescope OTA is an excellent choice. However, if you are interested in observing finer details of planets, galaxies, or other deep-sky objects, you may want to consider investing in a telescope with a higher magnification and shorter focal length. Additionally, it is recommended to purchase a finderscope to make it easier to accurately locate objects in the night sky.
This nice achromatic refractor was originally mounted on the superior Vixen Polaris equatorial mount which I am selling in a separate listing. I will carefully package the telescope so you can enjoy classic view as soon it arrives. Up for your consideration is a nice vintage Cometron C0-60E marketed by Palestrina and made Vixen in Japan the 1980 's. Get a piece of Vintage Japanese optical history as these don't pop up often.
