GSO Telescope N 305/1500 OTA (47050)

GSO Newtonian telescopes are renowned for their excellent optical quality and robust construction, making them ideal for both visual observation and astrophotography. Their sturdy mechanics are designed to support even heavy cameras, ensuring stability and precision during imaging. The larger 10" and 12" models have been eagerly awaited, as they provide exceptional views of the Moon, planets like Mars, Jupiter, and Saturn, as well as deep-sky objects such as nebulae and galaxies. These telescopes are fully optimized for astrophotography, offering a versatile solution for advanced users.

Advantages at a Glance:

• High-quality optics: Diffraction-limited parabolic primary mirror for sharp and detailed images.

• Durable construction: Solid metal supports for both the primary and secondary mirrors, with adjustable alignment.

• Enhanced contrast: Slim spider vanes on the secondary mirror to minimize obstruction.

• Advanced focuser: 2" Crayford focuser with 1:10 micro-reduction for precise focusing, even with heavy equipment.

• Generous focal plane: Suitable for both visual observation and photographic use.

• Efficient cooling: Primary mirror ventilation accelerates temperature stabilization.

• Powerful finder scope: Multi-coated 8x50 finder with a quick connector for easy object location.

The 2” Crayford Focuser with Micro-Reduction:
The focuser is a critical component of any telescope, ensuring accurate focusing and the ability to support heavy accessories. This telescope features a high-precision Crayford focuser with ball bearings and a 1:10 micro-reduction mechanism. It allows smooth adjustments even when handling loads over 3kg. With a positioning accuracy of less than 0.08mm, this focuser ensures precise focusing, making it suitable for high-resolution sensors in astrophotography.

Applications:
This telescope is perfect for observing the Moon, planets, nebulae, and galaxies while being fully suitable for astrophotography. It is not recommended for nature observation or solar viewing without appropriate filters.

Recommended Users:
This telescope is designed for advanced astronomers and observatories due to its size, weight, and capabilities. It is not recommended for beginners but provides exceptional performance for experienced users seeking detailed views and high-quality imaging results.
