Sky-Watcher Equinox 100 ED

The Sky-Watcher Equinox 100 ED 4 in f/9 refractor serves as my main telescope both for visual observation and astrophotography. The telescope comes with aluminum-lined wooden carrying case. It is supplied with two eyepieces: 25 mm and 5 mm. Supplied also is a 90-degree 2-inch diagonal mirror and an 8 by 50 finder scope.

The Optical Tube Assembly (OTA) features a 4-in f/9 extra-low dispersion (ED) apochromatic (APO) lens design. It has a 2-inch/1-inch dual-speed Crayford focuser with a thumbscrew underneath for locking the draw tube once focus is achieved.
