Off-Axis Guider - Tracking the stars the easy way
An off-axis guider provides an easy way of guiding the telescope for taking your astronomy photos. You do not need to mount a large and heavy guide scope, as this is easier - especially if your telescope cannot withstand much additional loading.
The off-axis guider is extremely compact and relatively lightweight. It is therefore also well suited for your photography using smaller telescopes / mounts.
An off-axis guider works really simply
The off-axis guider is easily slotted into your 2" focuser and clamped in place. It has a T2 thread on the camera side - standard for the easy adaptation of your camera. To take photos with a DSLR camera, you only need a matching T-ring - and that's everything.
When the light passes through the off-axis guider, a small amount is deflected via a small lateral prism. An additional 1.25" opening now lets you use your reticule eyepiece or an auto guider. You can then get started immediately after you have found a suitable guide star in the field of view.
Long exposures - Pin-sharp astronomy photos
You have probably seen many beautiful astronomy photos - magnificent galaxies with imposing spiral arms, red-glowing hydrogen nebulae, globular clusters whose countless stars look like they are embedded in velvet. All those photos were taken using long exposures - photos you can take using an off-axis guider.
You can now control the tracking precisely and achieve deep sky images with perfect pin-sharp stars.
Scops OAG is a motorised Off Axis Guider. Specialized for remote operation, allows you to adjust guide camera focus with great precision. Easy to be operated via ASCOM focus drivers or standalone software is going to make your life easier to guide your EQ-mount.
One cable operation
Scops OAG does not require an external controller. Its body includes all electronics and only one USB cable is plugged and provides power and control to the OAG.
Stepper Motor ensures focus precision
A stepper motor ensures absolute position of the focus point.
Profile each filter that might have a different focus position and just click the filter in the supplied software to precisely set the OAG to the stored position.
Large mirror
A large 10×10 mm fully multicoated & anti-reflection mirror offers full illumination to the guiding camera. Stars are round and bright across all the OAG ‘s field.
Adjustable prism height
The prism height can be adjusted to allow better illumination of the field of view of the guiding camera. If your imaging /main camera sensor is large the prism can be moved (with a set screw) upwards to disallow blockage of sensor’s optical path.
