Clear image for stable tracking<\/strong><\/h3>\n\n\n\n

The 50 mm lens captures a lot of light. Stars jump out and your guide camera finds a suitable target faster. Thus, your tracking remains constant and your shots stay sharp, even at long exposures.<\/p>\n\n\n\n

Smooth focusing<\/strong><\/h3>\n\n\n\n

The helical focus lets you focus quickly and precisely. Rotate until the star is perfectly in focus. This keeps your guiding reliable and you don't have to waste time.<\/p>\n\n\n\n

Extra long dew cap<\/strong><\/h3>\n\n\n\n

The long dew hood prevents the lens from fogging up. You can continue even on humid nights. This keeps your image clear and consistent.<\/p>\n\n\n\n

Secure attachment with Rotolock<\/strong><\/h3>\n\n\n\n

The Rotolock clamp keeps everything firmly fixed and centered. You can rely on stable images during observation or photography.<\/p>\n\n\n\n
