Home made CAT Cooler

[nathkrul]

Hi guys, thought I would show you my home made B&Q Cat cooler.

Cost was about £16 including glue, I used 21.5mm pipe and 2 reducers, couldn't find a square end for the fan so made do with the one in the photo.

I haven't glued the pipe into the other end incase I get an 11" cat later.

I used a piece of filter floss for the filter, I ran it for about 30 mins then checked for particles in the OTA floating about, there was none.

Presumiably this is to blow air in/out of the OTA via the eyepiece holder? Is it designed to blow air IN and allow it to find its own way out? or draw air OUT allowing it to find its own way in? or does it not matter?

Just curious as I am thinking of getting a Mak/Cas as my next upgrade.

Hi Bizbilder, it blows clean filtered air in, directed to the rear of the tube, warm air escapes through the eyepiece.
