Hi,
I recently purchased a ASI-1600 Pro camera, filter-wheel and power supply. I am very happy with everything and have 2 improvement suggestions.
The power supply should have a longer cable (at least 2 meter) between the camera connecting jack-plug and the power supply. The jack-plug could also have a locking-nut to prevent accidental disconnection from the camera.
Often the extension tubes/adapters tighten up too much and should therefore have ridges on the tubes to allow better grip when trying to unscrew the tubes.
