DEW HEATER FOR GLUED SECONDARY MIRRORS QHY25 For a better RGB colour

For a better RGB colour balance

it is possible to obtain a greater optical correction while maintaining the instrument extremely compact

corrected field ideal for astrophotography

This adapter is extremely short

This increases the filters durability and resistance to scratching

DEW HEATER FOR GLUED SECONDARY MIRRORS QHY25 For a better RGB colourThis dew heater is designed to heat the back of the Newtonian's secondary mirror. Newtonian telescope have open tube and that can facilitate the condensation of dew on mirrors, especially the secondary. Once the mirrors are fogged up, the telescope is unusable and cannot be dried up easily with paper. A heater can prevent this problem. Warning: make sure that the spade connectors do not touch as they may short circuit. It is recommended to wrap each
