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!

- Valuable tool
I bought this TOAG from OPTCorp, and have so far been quite pleased with it. The one thing that I will comment on is Orion's quality control. The package comes with a small Allen wrench to adjust the depth of the offset for the guide camera. The wrench they packaged with the unit was English and the size of the screws was metric. This made for a sloppy fit in the screw and an inability to tighten the set screws. It was easy enough to find a .5 Allen wrench but there really should be no excuse for sending the wrong tools with the unit. Other than this, I am very pleased with the TOAG, it is easy to use and setup, relatively, and an invaluable addition to my astroimaging arsenal.

Product QuestionsQuestion by: Spiezzy on May 13, 2014 10:57:38 PMThis 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 and has a 2' or larger focuser, it should be usable.Answer by: Chris (Admin) on May 14, 2014 1:28:31 PMDo 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.Question by: Mike Rogers on Jan 29, 2017 4:51:00 AMHello,
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!I'm using the atik 314l+ for imaging and Meade DSI for guiding. Will I need to purchase any additional adapters for the DSI?Question by: stouffer6244 on Dec 14, 2015 6:14:00 PMThe 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 have a USB relay box or something similar, you will also need an autoguider cable from Atik to connect from the 314L+ body to the mount's autoguider port (you will need to tell your guiding software to look for the guide commands from the main imaging camera relays rather than the guide camera relays.)Answer by: Chris Hendren (Admin) on Dec 15, 2015 6:19:00 PMI 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?Question by: Ali Al hawas on Sep 6, 2016 2:12:00 AMUnfortunately, 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 total length of 11mm to the bayonet (same as a Canon Wide-T ring). With the TOAG, you have the 10mm of the TOAG plus another 11mm for the T ring, and now your field is not flat when you add the Canon DSLR as you are too far from the flattener.Answer by: Chris Hendren on Sep 6, 2016 3:40:00 PMWhat adapters are needed to use the TOAG in the optical train with a Celestron SCT 6.3 focal reducer?Question by: Rudy on Aug 14, 2014 2:32:38 AMIf 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's CCD sensor is ~44mm from the male M42 T2 thread.Answer by: Chris (Admin) on Aug 15, 2014 11:48:43 AM
