When I started testing my point-and-shot camera doing afocal photography, I added an Orion SteadyPix Deluxe Camera Mount. However, when I pointed the LightBridge at a telephone pole in the distance for testing, the LightBridge tube was too top heavy.
I did some research and one common solution was to add some magnets. Though it wasn’t as easy to purchase some magnets that also had some weight, I eventually found enough and they acted as a counter-balance. It was nice in the end to have a number of smaller magnets because I could remove them if needed. I also got some felt to prevent any scratching.
