The mirror Cooling Fans System significantly reduces the amount of time spent waiting for reach the thermal equilibrium of the optics in the telescope. Observations can be started after 15-30 minutes (depending on the size of the mirror and temperature difference). Recommended especially for medium and large telescopes. The system additionally prevents the accumulation of a layer of warm air above the mirror, which has a positive effect on the contrast of the images.

Features:

• supply voltage: 12V – 8 AA batteries (to acquire separately)
• quiet fans (max 28dBA) operate without vibrations
• 4x faster cooling of the mirror
• simple assembly without the use of tools
• 3 large fans with a total efficiency of over 200m³ /h
• smooth, lossless fan speed regulation
• durable construction with a comfortable grip

The Cooling Fans fits the T300, T350 and T400 telescopes with the central hole M8. For the T500 and T600 telescope the fans are mounted directly to the mirror frame due to the lack of a central hole.
