What is the focal length of the Explore Scientific ED 100mm Refractor?

The standard Explore Scientific ED 100mm refractor has a focal length of 900mm, giving it an f/9 focal ratio. This longer focal ratio helps minimize optical aberrations, making it excellent for high-magnification viewing of planets and the moon.

Does the Explore Scientific ED 100mm come with a diagonal and eyepieces?

No, this telescope is sold as an 'optical tube assembly' (OTA), meaning it does not come with a star diagonal, eyepieces, or a mount. You will need to purchase a sturdy equatorial or alt-azimuth mount and accessories separately to use the telescope.

Is the Explore Scientific ED 100mm suitable for deep-sky astrophotography?

Yes, thanks to its Extra-low Dispersion (ED) glass, it provides excellent color correction, making it a solid, affordable choice for deep-sky astrophotography. However, because it is a relatively long focal length refractor, it requires a robust mount and a field flattener for optimal imaging.

What size finderscope fits on the Explore Scientific ED 100mm?

The telescope comes equipped with a Vixen-style dovetail shoe mounted on the tube rings. This standard design will accommodate most generic finderscopes with a Vixen-style foot, such as an 8x50 right-angle finder.
