Askar 15028HNT-AL Professional Astronomical Telescope F2.8 150mm Aperture Newtonian Reflector for Deep Space
Description:
- 15028HNT-AL is a hyperbolic primary lens Newtonian reflector with a diameter of 150mm and a focal ratio of ultra short F2.8.
- The 15028HNT-AL supports full frame shooting with a 44mm imaging circle and delicate star point performance.
- The focusing device of 15028HNT-AL is equipped with two built-in refractive corrector, one of which is made of ED glass, which enhances the ability to control color difference.
- The 15028HNT-AL further enhances the stability of the main lens optical axis in terms of mechanical structure design. Three sets of push-pull adjustment screws are designed at the bottom of the main lens barrel to adjust the angle of the main mirror.
- The 15028HNT-AL has improved the structure of the secondary lens bracket, making it more stable. The secondary lens bracket is manufactured using an integrated CNC manufacturing process, without misalignment, ensuring a beautiful and perfect cross shaped star during astronomical photography.
- There is a finderscope base on the side of the barrel, which can be used to install a finderscope or other required astronomical accessories.
- The focusing device of 15028HNT-AL is a large dual speed gear rack focusing device, which ensures a focusing stroke of 2cm as much as possible within the structural limitations and supports the replacement of electric focusing. The structure of the focusing device is very stable with a load capacity of 3kg. The back intercept also adopts the standard 55mm (calculated from the M48 threaded end face), making it easy for enthusiasts to get started.
- The dovetail board is of the standard Losmandy type, with a length of 200mm and a handle length of 200mm.
- 15028HNT-AL is made of all metal material, with aluminum lens barrel and CNC machined mechanical connection components.
Package Included:
- 1 x Telescope
- Businesses may need to employ various types of legal pages on their websites or mobile apps. Some, like Privacy Policies, are required by law, while others, such as a Terms and Conditions agreement (T&C), are not.
