ASKAR SQA130 f/4.8 APO QUINTUPLET is not in stock but it can be backordered.

The Askar SQA130 is an apochromatic quintuplet flat-field astrograph that offers high performance thanks to its air-spaced SD lens design. With a 55mm image circle support, a central star point RMS radius of less than 2 µm, and a full-field illumination of over 95% at 44 mm image circle, it ensures superb image quality. MTF data reveals excellent performance, with a super-fine star point of less than 2.4 µm at 55 mm.

Thanks to its Petzval design, you don't need to worry about reaching a precise backfocus distance. As long as you're in focus, you're good to go. Recommended sensor distance to the rear adapters is between 46 - 78mm.

The SQA106 comes with M68, M54 and M48 camera-side adapters for easy connection to typical imaging trains. A durable water resistant resin case with EVA foam interior keeps the telescope safe and has plenty of space for additional accessories.
