Are you shipping LRGB filters to vendors for the QHY9 ?
If so can you provide information about them.

Cold conditions for QHY9
« Reply #1 on: October 10, 2009, 08:51:26 AM »
After some more searching I found a previous thread for information about these filters.

Next question is has anyone used the QHY9 and filter wheel combo in extreme cold temperatures.
Heading into the winter brings sub zero temps and it would be helpful to know if the materials used for these components can handle the cold.

Thanks in advance
