Description This product can be used for:1. Observe the starry sky. For example, observing craters on the moon, observing planets, observing rings on Saturn, observing Jupiter, and so on2. It can be used for beginners or beginners in astronomical photography to capture celestial bodies such as the moon and planets. Moreover, because this product uses a two inch interface, it can be used on full frame cameras. Of course, as an astronomical photography, it is not as good as a professional ED APO. However, as a beginner in photography, the price is less than 1/4 of the APO, and the cost-effectiveness is relatively high (photography requires the corresponding camera adapter to be selected)3. This product can be used as a guide scope and has a standard Vixen dovetail plate, which can connect most astronomical telescopes and tripods4. This product can also be used to observe the ground (additional positive zenith mirror is required), using it as a shooting scopeProduct features:1. Pure optical glass objective, using full multi-layer broadband green film to maximize the transmission of light. Full coating means that all surfaces of all lenses are coated, while low-quality telescopes only have one outer surface coated2. Adopting an air dual separation achromatic design. Compared to traditional glued lenses, the performance is superior and the image is clearer. Of course, there is still a significant difference between apo and apochromatic aberration (APO), as the price of APO is usually quite expensive, at least four times that of this product. Therefore, the cost-effectiveness of this product is still very high.3. Equipped with a standard Vixen dovetail groove connection plate, it can easily connect other telescopes and tripods4. Equipped with all metal clamps and handles, convenient for carrying and transportation5. Sampling a two inch focusing socket, while traditional astronomical telescopes typically use a 1.25 inch focusing socket, which can only connect 1.25 inch eyepieces and half frame cameras. Our product uses a two inch interface and is equipped with a two inch to 1.25 inch interface, making it easy to connect 1.25 inch and two inch eyepieces, whether it is a half frame or full frame camera, All can be connected (corresponding camera T ring needs to be selected separately)6. A very suitable focal ratio design, as well as a relatively light weight and compact size, is very convenient to carry7. Equipped with objective lens cover and eyepiece cover to prevent dust from enteringExplanation:This product is only an OTA (Only tube assembly) and does not include eyepieces, zenith mirrors, tripods, camera rings (these require optional accessories, which are common to most astronomical observers and can also be used on other astronomical telescopes)Descriptions:
