Orion 70mm Multi-Use Finderscope
Build your own custom telescope aiming device with the modular Orion 70mm Multi-Use Finder Scope. This finder optical tube allows you to customize your own 70mm optical finder scope by adding optional eyepieces, diagonals, video cameras, and more to create a complete finder solution for your telescope.
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.
In order for the Orion 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 22x70 finder scope with powerful 22x magnification. Alternatively, you could use the Orion 20mm I.C.E. eyepiece to create a custom 14x70 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. By attaching a diagonal along with a StarShoot Deep Space Video Camera II, you can make your own 70mm video-finder! You can even use the 70mm Multi-Use Finder Scope as a compact, wide-field f/3.9 telescope or spotting scope by adding a combination of a standard 1.25" telescope eyepiece and a 1.25" prism or mirror diagonal. (All eyepieces, diagonals and astrophotography accessories sold separately.)
For astrophotographers, the Multi-Use Finder Scope's big 70mm aperture is especially beneficial when used along with a diagonal and the Orion StarShoot AutoGuider for 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 1.2 lbs. 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!

Product QuestionsI am looking for a replacement finder for my 8" Meade LX200 GPS. Was wondering how this would work. What is the length of this item and would I need to replace the mount?Question by: Laurel_Florida on Mar 5, 2017 5:01:00 AMThis finder would be a nice upgrade to the old 50mm finder your scope came with. You would need an OR-7215 SCT finder base from Orion and a 1.25" diagonal and eyepiece (all sold separately) to use this finderscope. The scope is ~8.25", but it will be closer to 10" long with the diagonal installed.Answer by: Chris Hendren (Admin) on Mar 15, 2017 4:14:00 PMQuestion by: gooseguerra on Nov 25, 2014 1:25:59 AMAccording to the manufacturer, in order for the Orion 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.
