Same scenerio with DSO imaging no doubt.

I have to agree with this finding. I find the CF tube struggles to cool down if there is a temperature drop. My metal Meade 8" sometimes wipes the floor with the C11 with planets on a cool night as it reaches ambient much quicker. But for long exposure photos the CF holds focus very well.
