William Optics Adjustable Flat73A for Z73

The William Optics Adjustable Flat73A is a specialized field flattener designed to optimize the performance of the Z73 telescope for astrophotography. This accessory corrects field curvature, ensuring sharp, well-defined stars across the entire image frame.

Compatibility

---

The Flat73A is custom-made to work seamlessly with the William Optics Z73 telescope. It's designed to provide optimal performance with this specific optical system, ensuring the best possible results for astrophotography.

Adjustable Design

---

Features an adjustable mechanism that allows fine-tuning of the spacing between the flattener and the camera sensor. This 0-15mm adjustability ensures optimal performance with various camera models and configurations.

Construction

Built with high-quality materials and precision optics to maintain the excellent performance of the Z73 telescope. The robust construction ensures durability and stability, critical for long-exposure astrophotography.

Integrated Field rotator

The William Optics FLAT73A features an integrated rotator, enhancing the telescope's versatility and ease of use for astrophotography. This rotator allows for precise adjustments of the camera's orientation, enabling photographers to easily frame and compose their images without the need to reposition the entire setup. This is particularly useful when aligning the camera to capture specific features of celestial objects or to optimize the field of view. The integration of the rotator into the FLAT73A's design ensures a seamless and stable connection, reducing the likelihood of mechanical flexure and maintaining the optical alignment for sharp, clear astrophotographs.

Optical Performance:

The Flat73A effectively corrects field curvature inherent in the Z73 optical design. This correction results in significantly improved edge-to-edge sharpness and reduced abberations over a 43mm image circle, particularly noticeable when used in conjuction with large camera sensors.
