Introducing Askar's SQA70 Telescope: A Compact High-Performance Astronomical Tool

Askar Unveils the SQA70 Telescope

Askar, a promising name in astronomical tools, is set to release its latest product, the SQA70 Telescope. Starting on April 18, 2025, customers can place advance orders for this innovative telescope, featuring a 70mm aperture and compact design, alongside optional accessories like a specialized handle and a 20mm spacer.

Key Features of the SQA70 Telescope

The SQA70 is designed with a high-performance Petzval optical system, consisting of five elements in five groups, two of which are ED (Extra-Low Dispersion) lenses, ensuring superior image quality. With an aperture of 70mm and a focal length of 336mm, the telescope is capable of delivering excellent images of celestial bodies when paired with various full-frame cameras, providing an image circle of 44mm. This ensures ample versatility for astrophotography enthusiasts.

One of the standout characteristics of the SQA70 is its impressive F4.8 aperture ratio. This relatively bright specification allows astrophotographers to capture high-quality images with minimal noise, even during shorter exposures. The telescope boasts over 90% illumination in the image circle, providing a consistent and uniform quality across the field of view, making post-processing much smoother.

Flexible Connectivity Options

The SQA70 has a back focus range of 37mm to 68mm, accommodating various camera systems and accessories with ease. Its adaptable optical design allows seamless integration of filters and other gear without altering the light path. Included with the telescope are adapters of different diameters: M42x0.75mm, M48x0.75mm, and M54x0.75mm, which ensure compatibility with a range of equipment.

Designed for Astrophotography Enthusiasts

This telescope is engineered keeping the needs of astronomy lovers in mind. It features a finder bracket that can hold two accessories simultaneously, allowing users to attach both a guide scope and finder. Additionally, the 34mm wide dovetail bar enables convenient mounting options across various setups, making it flexible for different astrophotography configurations.

Crafted with precision in a CNC facility, the sturdy build of the 100mm long tube band provides resistance against twisting and bending while maintaining a lightweight profile. Moreover, its retractable dew shield enhances portability, allowing for a compact design when not in use.

The SQA70's focuser is compatible with many third-party electric focusers, and it features a dual-speed mechanism for enhanced accuracy during focusing. Furthermore, the eyepiece section incorporates a 360-degree rotation device for precise alignment of the view, essential for capturing celestial images. Along with a semi-hard case for convenient transport and storage, the SQA70 is a comprehensive package for any astrophotographer.

Rigorous Quality Assurance

As part of its commitment to quality, Sightron Japan conducts thorough inspections of the SQA70 in its dedicated facility in Niigata. Every product is checked for both appearance and optical alignment, ensuring that only those meeting their strict standards reach the consumer.
