50mm Guide Scope Multi-Use CCD Imaging with Helical Focuser for Astronomy Camera Black
This solidly built 50mm Guide Scope will help guide you to capturing higher quality astrophotos. With its 50mm lens and smooth helical focuser, the versatile 50mm Multi-Use Guide Scope with Helical Focuser is an ideal addition to any astrophotographers collection of gear. What's more, you can use this handy scope as a deluxe, straight-through 50mm finder by inserting an optional 1.25" eyepiece (sold separately). A practical benefit of this is that prior to guiding, you can insert an eyepiece into the guide scope and easily align the guide scope with your main imaging telescope. Then remove the eyepiece and attach your autoguider camera.
For those nights when you don't plan to capture astrophoto exposures, this versatile Guide Scope can double as a straight-through finder scope with an optional 1.25" eyepiece installed. For example, inserting a 20 mm eyepiece creates a 9.5x50 finder scope, or you can insert one Illuminated Centering Eyepieces for use as a finder with illuminated crosshairs for easy aiming. (Eyepieces sold separately).
