    Orion Thin Off-Axis Guider (TOAG)

    Add autoguiding accuracy to any astrophotography setup with the affordable Orion Thin Off-Axis Guider. This versatile accessory lets you image and guide through a single telescope without the need for a separate guide scope!

    Its thin, 10.5mm profile makes the Orion Thin Off-Axis Guider a unique and versatile offering to today's astrophotographers. It's ideal for use with Newtonian reflector telescopes which have limited "back focus" travel. Until now, astrophotographers who used Newtonian reflector telescopes had to use a separate guide scope to add autoguiding accuracy to their images. With the convenient Thin Off-Axis Guider, you can guide and capture astrophotos using one telescope - no guide scope required! Using the Thin Off-Axis Guider for Astrophotography will help you save time and reduce the weight and bulk of your imaging system while eliminating pesky tracking errors.

    Designed for use with the Orion StarShoot AutoGuider (sold separately) and similar small-chip autoguiding devices, the Orion Thin Off-Axis Guider features lateral adjustment capability which can effectively double the prism's width for increased versatility.

    This handy astrophotography accessory comes with a host of useful adapters including a C-mount to T-threads adapter, Canon DSLR bayonet adapter, Camera T-adapter, ultra-thin M48 male to T-adapter female adapter, 3mm Coma-Corrector spacer, 18mm spacer, and a 2" nosepiece. Thanks to these included adapters, the Orion Thin Off-Axis Guider for Astrophotography will work with many imaging systems right out of the box.

    Whether you use a Newtonian astrograph, Schmidt-Cassegrain, or other telescope for your astrophotographic pursuits, get the Orion Thin Off-Axis Guider for Astrophotography and start enjoying increased accuracy in your photos of the cosmos!

    Questions & Answers

    Ask a Question
    • hi there will this work on a refractor telescope ???

      This will work as long as you have enough back focus to fit it and all of your camera adapters into the light path. It will work with most flatteners and will not work with most focal reducers. If the refractor was designed by the manufacturer for imaging

    • What adapters are needed to use the TOAG in the optical train with a Celestron SCT 6.3 focal reducer?

      If using a Canon DSLR, the only needed adapter is the CE-93633-A as the TOAG comes with a female M42 T2 to male M48 adapter and a Canon EOS bayonet adapter. If using a CCD camera, you also need a spacer from the TOAG to the camera so that the camera'

    • I'm using the atik 314l+ for imaging and Meade DSI for guiding. Will I need to purchase any additional adapters for the DSI?

      The DSI will thread directly to the OAG guide camera stage, but you will need to use additional T thread spacers between the OAG and the main camera, and the length will change based on whether you are using a filter wheel or not. If you do not already h

    • I am using Skywatcher Refractor Espirt 100ED, field flattener came with the scope and a canon dslr.. do I need any extra adapters to use this TOAG?

      Unfortunately, there is not enough back focus to use the Orion TOAG between the Esprit 100 flattener and a DSLR. For a Canon DSLR, you are better off using the TS-TSOAG9EOS, which has an M48 thread on the scope side (fits the Esprit 100 flattener), and a

    • Do you have a helical focuser that can me attached to the prism shaft? Not the Baader one because it rotates the camera as you focus from what I've read. The helical focuser would make it easy to focus a system that is typically hard to focus. Thanks.

      Unfortunately, no. The Baader one will work, but it does rotate the camera. The best solution may be to look at a Borg helical focuser and machine an adapter to the TOAG - but that setup would cost more than the OAG and so may not be feasible.

    • Hello, Does TOAG fit directly M48x0.75 flattener connection? How deep is M48x0.75 thread on TOAG? (my flattener have a 5mm male M48x0.75 thread). Thanks!

      Yes, it does. The depth of the thread is 6mm deep. Thank you, Sean 760-400-0235

    • Hi Can I use the Lacerta M-GEN II camera with this TOAG.. ? Do I need any adapters ? Thanks

      This camera should thread directly onto the OAG with no additional spacing required. If you need further assistance please call or email us and we will be happy to help.
