Whether you use a DSLR or a cooled dedicated astronomy camera, the Sky-Watcher Esprit 100ED is a high-quality, compact, and capable telescope ideal for deep-sky astrophotography and a superb instrument for visual use as well.
The Explore Scientific ED80 Essentials Triplet is a poor choice for most astrophotography work compared to competing telescopes, and the scope’s triplet optical design has little correlation with high quality.
The Sky-Watcher Evostar 80ED (formerly the ProED 80) is an excellent visual and astrophotography telescope, though not the fastest f/ratio or widest field option out there.
The William Optics ZenithStar 73 III is an ideal telescope for wide-field deep-sky astrophotographers, regardless of whether you’re a beginner or an experienced imager.
The William Optics ZenithStar 81 is a great telescope for beginner astrophotographers and provides excellent value for the money, though it’s a little more demanding than smaller aperture instruments and slower in focal ratio.
The William Optics ZenithStar 61 is a great starter telescope for deep-sky astrophotography and offers good value for the price.
Vaonis’ Stellina is arguably the iPhone – or iMac – of astrophotography telescopes.
