The Explore Scientific 10×60 Finder and Guider Scope (item 0620180) works two ways: as a 10×60 illuminated-crosshair finder, and, with the eyepiece unit removed, as a 250 mm focal-length guide scope for autoguiding.
The removable eyepiece unit has an adjustable red-illuminated crosshair with 0.85° scale markings, which you can focus separately from the main image. Explore Scientific specifies a 6.0° field of view and fully multi-coated (FMC) lens surfaces. With optional 1.25-inch eyepieces of about 5–26 mm focal length, magnifications of about 9× to 50× are possible, so the scope can also serve as a small travel telescope.
Remove the eyepiece unit and attach a guide camera through the 1.25-inch push-fit, held by a brass clamping ring and three screws, or the T2 (M42 × 0.75) thread. The focal plane lies approximately 22 mm behind the T2 thread. A precise helical focuser with a laser-engraved 0–28 mm scale lets you return to the same focus position each night. Explore Scientific specifies a maximum camera weight of 550 g.
The all-aluminium finder bracket has six large knurled adjustment screws with plastic tips. It fits Explore Scientific and Bresser Messier finder shoes, and a matching finder shoe is supplied. The shoe attaches to the tube with four M5 screws, and its holes are spaced 31.7 mm on both axes.
