Review ASKAR 65mm F/6.4 Quintuplet Flat field Astrograph

The AskAR 65PHQ is a high-performance 65mm f/6.4 Quintuplet Flat-Field Astrograph designed specifically for astrophotography enthusiasts seeking exceptional image quality and versatility. This telescope boasts a six-element Quintuplet design, which consists of five high-quality glass elements to provide excellent image sharpness, contrast, and color correction.

The f/6.4 focal ratio offers a balanced combination of light grasp and image scale, making it suitable for a wide range of astronomical targets. The telescope is optimized for use with full-frame and cropped-sensor DSLR cameras, enabling capturing high-resolution images with excellent detail and clarity.

The AskAR 65PHQ comes with a 650mm focal length and a 2.4-degree field of view, providing a generous imaging area for capturing large deep-sky objects and star clusters. Its parabolic primary mirror ensures accurate focus and minimizes coma and field curvature, while the secondary mirror features a low-scatter coat to reduce internal reflections and improve contrast.

The telescope's flat-field design is an essential feature for astrophotography, as it minimizes vignetting and ensures a uniform illumination across the entire imaging sensor. This results in evenly exposed images with consistent color and detail from edge to edge.

The AskAR 65PHQ features a robust and well-engineered construction, with a tube length of 520mm and a total weight of approximately 13.2 lbs (6 kg). It is made from high-quality aluminum and coated with a durable anodized finish to withstand the rigors of regular use and outdoor conditions.

The AskAR 65PHQ also includes a Vixen-style dovetail mounting plate for easy attachment to various mounts and tripods, making it a versatile and adaptable choice for astrophotography enthusiasts. This telescope is an excellent investment for those seeking exceptional image quality, versatility, and a wide field of view for their astronomical imaging projects.

If you are an astrophotographer looking for a high-quality, flat-field telescope for capturing detailed images of the night sky, the Askar 65PQ is an excellent investment. However, it may not be the best choice for those on a budget or those who prioritize a wider field of view over flat-field performance. Carefully consider your observing goals, budget, and equipment requirements before making a decision.

Details:

The scope is in excellent condition and has only seen light use. The optics are clear. I'm asking $525 for the scope and rings. I had the rings made so that could easily mount a Losmandy plate on to for computer.

There are three minor kicks to the finish on OTA, all shown in photos. It is approximately one year old, and I am the original buyer. For sale is my Askar 65PHQ, with custom rings by Roux Astro. They are surface blemishes only.
