Depending on your particular aiming needs, it’s easy to customize the 70mm Multi-Use Finder Scope so it will provide optimal aiming for your astronomy setup. Since the 70mm aperture lens is capable of gathering twice the amount of light compared to a 50mm finder scope, you’ll be able to aim your telescope with the help of brighter, more detailed views of starry skies. Six adjustable alignment thumbscrews on the Multi-Use Finder Scope’s mounting bracket make it easy to accurately align the finder with your telescope.

Add Prism and Eyepiece of your Choice

In order for the 70mm Multi-Use Finder Scope to reach focus, an 1.25″ mirror or prism diagonal is required along with an 1.25″ telescope eyepiece, illuminated reticle eyepiece, imaging camera, video camera, or autoguiding device. With approximately 10mm of focus travel and helical focus adjustment, you’ll be able to achieve sharp focus through the 70mm Multi-Use Finder Scope with most combinations of diagonal and eyepiece, or diagonal and imaging accessory. (All eyepieces, diagonals, and astrophotography accessories sold separately.)

For visual observers, you can attach either a 90° or 45° prism or mirror diagonal and an 1.25″ illuminated reticle eyepiece to create your own custom 70mm angled finder scope. If you use the Orion 12.5mm Illuminated Reticle Eyepiece with the f/3.9 Orion 70mm Multi-Use Finder Scope, it becomes a 22×70 finder scope with powerful 22x magnification. Alternatively, you could use the Orion 20mm Illuminated Centering Eyepiece to create a custom 14×70 finder scope for a wider, 14x magnification view. A mirror or prism diagonal is required along with an eyepiece in order for the 70mm Multi-Use Finder scope to achieve focus. (All eyepieces, diagonals and astrophotography accessories sold separately.)

A lightweight 70mm Guider

For astrophotographers, the Multi-Use Finder Scope’s big 70mm aperture makes it well suited to guided imaging sessions. Compared to smaller aperture guide scopes, the 70mm lens of the Multi-Use Finder significantly increases the amount of potential guide stars visible in a given area of night sky. This makes it easier to find, acquire, and utilize a guide star with the StarShoot AutoGuider in order to capture sharp, precisely guided astrophotos. A prism or mirror diagonal is required in order for the StarShoot AutoGuider to reach focus when used with the 70mm Multi-Use Finder Scope. (Diagonals and StarShoot AutoGuider sold separately.)

Weighing in at 550g without any diagonal or other required accessories installed, the lightweight Orion 70mm Multi-Use Finder Scope allows you to create your own unique aiming device and you can easily swap out optional accessories to alter the finder’s features. It’s like having multiple finder scopes in one!
