At very cold temperatures, blocking filters may no longer work accurately central in the H-alpha wavelength, which means that the details on the sun become less visible. With this Heating-Module you can counteract this effect and observe the sun in the H-Alpha line optimally even at cold temperatures.
The Heating-Module is for use with blocking filters in 90° star-diagonal housing from Lunt Solar Systems. It cannot be used at blocking filters in straight extension tube.
