- Built to Perform: Precision machining, retractable dew shield, and 360° rotator streamline every imaging session
Askar SQA130: Advanced Quintuplet Astrograph for Brilliant Deep-Sky Imaging!
Introducing the Askar 130mm Quintuplet - bringing big-time imaging power in a sleek design! Featuring a Petzal-structure with two pieces of SD (super-low dispersion) glass elements, this delivers crisp stars across your entire sensor. With a fast 624mm focal length and f/4.8 focal ratio, this astrograph is built to soak up faint galaxies and nebulae with ease, all while supporting a spacious 55mm image circle for today’s large sensors. Just attach your camera and start imaging! Add optional handy accessories like the 20mm extension tube or carrying handle, and you’ve got a powerhouse that’s as enjoyable to use as it is to shoot with.
Askar SQA130 Highlights
All-In-One Imaging Powerhouse
Beyond the SQA130s exceptional optics, it comes ready for serious astrophotography with a 360° camera rotator, retractable dew shield, and included M68-M54-M48 step-adapters for easy connection to various cameras. From full-frame imaging to wide-field deep-sky captures, this astrograph delivers precision, convenience, and versatility in a single package.
Edge-to-Edge Clarity
The Quintuplet air-spaced lens design, including two pieces of SD glass, minimizes chromatic aberration and color-accurate stars. While the Petzval configuration inherently flattens the imaging plane, ensuring sharp stars from center to edge without the need for an additional field flattener. The simplified back focus requirements make the 130 compatible with astronomy and DSLR cameras with appropriate adapters.
Secure and Flexible Mounting Options
The SQA130 comes with sturdy tube rings mounted on a solid 300mm Losmandy dovetail plate, ensuring secure, vibration-free support for your telescope. For added versatility, it accommodates optional accessories like a heightening section, letting you fine-tune the vertical position for optimal balance and framing. The top of the rings also provides a convenient mounting point for an additional handle, making transportation quick and easy.
Thoughtful Features for Astrophotographers
Make astrophotography effortless from setup to imaging! The SQA130 features a sturdy 300mm losmandy-style dovetail plate ensureing quick and secure mounting, while the M48, M54 and M68 adapters make attaching cameras, reducers, and filters simple. The retractable dew shield protects the optics from condensation without adding bulk, and the telescope’s built-in field flattening guarantees sharp stars across the frame with no extra flatteners or spacing calculations. Combined with its generous back-focus range (46mm to 70mm) and compatibility with optional accessories like extension tubes and carrying handles, the SQA130 streamlines every imaging session, letting photographers focus on capturing the night sky rather than wrestling with gear!
Optical Performance Made Simple
The SQA130 is designed to deliver extremely sharp and evenly illuminated images across multiple camera sensors. Its spot diagram performance shows that stars stay incredibly tight and round, less than 2 microns in the center meaning minimal star distortion. The relative illumination results highlight that the lens keeps the frame bright from corner-to-corner, maintaining over 85-95% brightness depending on sensor size, reduceing darkened edges. Finally, the MTF chart demonstrates the lens’s ability to maintain both high detail and strong contrast acrossthe entire 55mm image circle, confirming its excellent sharpness and control of optical aberrations! Altogether, these diagrams confirm clearer stars, even exposures, and overall higher-quality images with less post-processing needed!
Robust Dual-Speed Focuser
Featuring a 3.2-inch dual-speed rack-and-pinion provides both coarse and fine adjustments for precise focusing and smooth stable movements! Its CNC-machined barrel is finished with anti-reflective matte paint to minimize stray light, while a generous focusing travel is 30 mm focus travel accommodates a wide range of cameras and imaging setups. The engraved scale tops off this carefully crafted focuser by allowing you a reliable way to return to the exact focus positions, making this focuser ideal for astrophotography and detailed celestial observation.
