174mm-mini protective window ring very loose

mjmonson

Hello. I have had my 174mm-mini for several years, it it a great camera. When I use it in an OAG, the extension tube comes off. When I use it in a guidescope, the extension tube comes off. The problem I am having is the black ring, that the protective window is glued too, is very loose and keeps coming off, leaving the sensor exposed. I thought of dipping a small amount of threadlocker on it, but I am sure what chemicals will impact the adjacent senor.

Does anyone have some method to make that ring stick on the camera better? Thanks for the help-

Avoid using thread lockers as they may cause damage to the sensor or other parts inside the camera. Use a non-permanent glue such as silicone or liquid gasket to increase the stability of the black ring, but make sure it will not cause damage to the sensor.
Check the threads of the protective ring to make sure there is no damage, as thread wear may cause it to loosen. If the threads are damaged, you may need to replace the part.
