Cat Cooler by AstroDude_1983

I designed this for my Nexstar 11 GPS wich has a 2" click lock.
Can be used on smaller SCT's, just make shure you shorten the tube if needed.
Not so happy with the fan though, i expected more airflow.
If anyone has a beter suggestion, i'd love to hear it.
Edit: this may seem obvious, but just wanted to add this remark : this cooler only works on non-EdgeHD ota’s because of the corrective elements in EHD optics.
