    Default polar guiding and and off axis guiding



    I'm a beginner and new here, I'm am purchasing an ioptron sky guider Pro with I-polar polar guider and I am thinking of also OAG Off Axis Guiding through my main scope for astro photography wits a separate camera. Is that dual redundant ? In other words will I only use one or the other when guiding or are they used in conjunction. I plan to do some landscapes with star and guiding but I also plan to do some deep space nebular imagery as well. For now both using a dslr or mirrorless camera with various standard camera lenses however I also plan on using Stellarvue 70mm telescope for the nebular imagery. If the procedure for guiding only uses one or the other methods I can landscape guide with the ipolar and deep space guide with the ZWO 290 mini camera but is this necessary? I'm trying to get the setup in my mind. Is the OAG too much being I have the I-polar or are both independently useful tools? Also do they use the same software.

    The iPolar appears to be a polar alignment aid. You would use it once, when setting up the mount. It would not be used during a photo session.

    The OAG is for a different purpose. The guide camera connected to it will make adjustments to a mount's tracking while the photo session continues.

    Given that you are just starting out, I would recommend not getting the OAG right away. It is just one more device to attend to. Instead, learn to set up your mount, polar aligne it (with the iPolar, if you so choose) and take pictures first, before adding complexity to your rig.
