Askar 107PHQ Astronomical Telescope High Performance Long Focus Ratio Flat Field Astronomical Telescope

Askar 107PHQ Astronomical Telescope High Performance Long Focus Ratio Flat Field Astronomical Telescope

Description:
- As Askar's first long focal ratio, self leveling field camera lens, 107PHQ has its special mission. Both beginners and experienced enthusiasts can easily use it. Beginner enthusiasts no longer need to purchase additional flat field lens for photograph purposes, nor do they need to calculate the back intercept of the flat field lens or cumbersome connections to match the distance. They can directly connect to any imaging accessory, and after focusing, it is the best shooting state, which is easy to handle, giving you more time to invest in other photograph tasks.

- ASKAR 107PHQ is a truly versatile player. It is a telescope that is suitable for almost all purposes, which is precisely the purpose of its launch.

- 107PHQ adopts a quadruplet optical lens combination with a focal ratio of 7, with two of them being ED glass. Therefore, 107PHQ has excellent color difference control ability, which can effectively correct color difference issues even when visually magnified to 300 times.

- Due to its flat field design, 107PHQ has strong advantages in astronomical photography. It not only supports full-frame digital SLR 44mm image circle, but also has minimal deformation of surrounding stars. The RMS radius of the central star point in the field of view is only about 3 microns, and the stars are delicate, which can meet the strict requirements of experienced players for stars. The overall image field is very flat, and the surrounding dimming is also excellent.

- With a focal length of 749mm and powerful image field correction, when paired with a high-resolution camera for astronomical photography, the fine details of celestial bodies can also be easily captured.

- Using 107PHQ for visual observation is also an ideal choice, whether it is connecting with a 1.25 inch, 2-inch zenith lens, or various eyepieces, it can easily focus, and even observe planets at ultra-high magnification.

- All 107PHQ lenses are processed using high-quality CNC technology and spray coating, with unique green decorative parts that are eye-catching and aesthetically pleasing. The highly rigid 3.4inch large focusing device fully meets the needs of observation and photography. The focusing device has been optimized specifically for photography and can carry a load of up to 8 kilograms. The focusing stroke range is very large with a maximum of 95 millimeters.
