Large aperture, direct results
The Skywatcher N 305/1500 offers a 12-inch parabolic mirror that captures 44% more light than a 10-inch model. This allows you to see brighter stars and deeper nebulae. Even faint objects from the NGC catalog come within reach. The f/4.9 optics allow you to observe bright details of planets and the Moon.
Flexible and easy to transport
Thanks to the patented FlexTube system, you slide the telescope in or out. The construction is light and compact, but remains sturdy. Within seconds, the tube is operational and collimated. Ideal for traveling or moving to a dark observation spot.
Precise focusing with Crayford focuser
The 2″ Crayford focuser moves smoothly and keeps eyepieces and cameras stable. The T2 connector makes it easy to connect DSLR cameras. Focusing is precise, keeping stars pointed and details razor-sharp.
Complete and ready to use immediately
The telescope comes with a rocker box, reinforcing support pillars, 25 mm and 10 mm eyepieces, 2″ Crayford focuser with 1.25″ adapter, T2 connector and a 9×50 viewfinder. The central marking on the main mirror makes collimation easy.
