William Optics Pleiades 111/528 APO Septuplet Astrograph OTA

William Optics 111 AP 111/528 - Fast astrograph for perfect shots

The William Optics 111 AP 111/528 is a powerful apochromatic refractor designed specifically for astrophotography. With the quadruplet lens and FPL-53 glass, you get sharp, clear images. Full-frame sensors are fully utilized, making stars and nebulae look fantastic.

Photographing quickly and efficiently

Thanks to the very fast f/4.8 focal ratio, you can use short exposure times. That means less waiting time and less motion blur. Perfect for deep-sky photography, but also ideal for planets and the Moon.

Internal focusing system (WIFD)

The Internal Focus Design lets you focus accurately without external rotations. Even heavy, cooled cameras are no problem. Focusing is smooth and precise, with an integrated scale. Compatible with the ZWO EAF for automatic focusing.

Compact and travel-friendly

Despite the 111 mm aperture, the telescope remains surprisingly portable. You easily take it with you in the included transport bag. The practical handle and Vixen/GP prism protection make mounting and transport easy.

Complete and versatile

The Pleiades 111 comes with Bahtinov focus mask and adapters for DSLR and CCD cameras (M48 and M54). It supports Canon, Nikon, Sony, Pentax, Fuji and Micro Four Thirds with optional T-adapters. You get a high-quality astrograph that is ready to use immediately.
