Worth attaching a cooling fan?


Recommended Posts

Hi,

Just ordered my new SW Explorer 150P! Can't wait for it to arrive (and the skies to clear), but was wondering of it is worth me making something so I can attach an old computer cooling fan on the back of it? Would this fan be alright, is it even worth doing on a 6" scope? I also read on another forum that leaving it on just enough to keep it turning can help with the image on planetary viewing, is this true?

Thanks!

Tom

No, when observing is best turned off for stable views. Prior to observing it will acceletate equilibration of the primary to ambient temparature. For a small 6" mirror not really worth the effort as that will cool relatively fast. Enjoy your new scope Tom !
