Best way of adding primary fan to Skywatcher flextube?

[mbaddah]

What's the best and methodology of attaching a fan to a 10" skywatcher flextube for cooling the primary mirror? Seems like there are so many opinions out there!

Greatly appreciate the help thanks.

Moh,
I suggest that you ask Trevor (MAS) he attached a fan to his Skywatcher 12".
Does your scope have holes in the rear cell where the fan would be mounted? If yes, you can use screws or small cable ties to hold the fan to the cell.:)

I just checked the bottom of the tube and there are four holes indeed! Sweet I should just look for same fan size? Will this introduce vibrations and if so is there a way to minimise it?

Thanks John. Will ask Trevor as well.

An 80mm Muffin Fan will do the job. I have the fan (on my 12" LB) on all night without any vibration problems.:)
