Is there a telescoping extension for the OSMO or OSMO 2?
and is there a way to use this extension along with providing external power to the OSMO?

Any tips to point me along a path to find a way?

The application here is generally for recording from a moving vehicle (off road) with the passenger using the camera on an extension out the window to record all around the vehicle.  Its bumpy so a gimble is necessary.  We are not happy with the GoPro solution we have been using especially battery life.

Any tips are appreciated.

Thank you!

Hello there. Good day and thank you for sharing these information with us. Since this is a 3rd party accessory for the DJI gimbal I hope that you will get the best recommendation from our fellow DJI members who have tried using the said accessory on there DJI gimbal. Just a reminder that DJI does not recommend you to your 3rd party accessories on your DJI products. These 3rd party accessories might affect the said DJI gimbal when in use and there is a possibility that these 3rd party accessories will be able work. However, since it's not optimized and tested by DJI we cannot guaranteed the stability of the said 3rd party accessory if it will work all the time with no issues and might damage and void the warranty of the said DJI product as well. Thank you.
