Sky-Watcher Evostar APO

The doublet design uses two lens elements, which makes the telescope lighter and faster to cool down than a triplet. While triplets offer slightly better color correction, the Evostar’s extra-low dispersion glass is highly effective at minimizing chromatic aberration, delivering sharp, high-contrast views that satisfy most serious observers.

It is a true hybrid. The 150mm aperture and f/8 focal ratio provide excellent light-gathering power for deep-sky visual work, while the high-transmission coatings and dual-speed focuser make it a capable instrument for planetary and lunar imaging.

Because the tube weighs 20.5 lbs, you will need a sturdy equatorial or alt-azimuth mount with a Vixen-style saddle. A mount with a payload capacity of at least 30 lbs is recommended to ensure stability, especially if you plan to attach a camera or other accessories.

Yes, the 10:1 reduction ratio on the dual-speed Crayford focuser is essential for fine-tuning focus. It allows you to make microscopic adjustments that are critical when viewing planets at high magnification or locking in focus for long-exposure photography.

While it is a substantial instrument, the doublet configuration keeps the weight manageable at 20.5 lbs. The included aluminum case makes transport safer, but you should still plan for a dedicated setup space rather than frequent travel.

The package includes the tube rings and a Vixen-style dovetail, which covers your mounting needs. However, you will still need to purchase eyepieces, a diagonal, and a finder scope separately to complete your visual setup.
