Wrap-around Secondary Mirror Heater for mirror on 1.25 inch stalk
Dew accumulation on the secondary mirror of Newtonian telescopes is a common issue, particularly for models with an open tube, such as “Collapsible Dobsonian” or “FlexTube” designs. While a long Dew Shields can offer partial protection, it often falls short during high-humidity nights. The most effective and reliable solution is the use of a Secondary Mirror Heater. This accessory, combined with a Dew Shields, provides comprehensive moisture control, ensuring prolonged and uninterrupted observation sessions.
Innovative and Efficient Heating Solution
The R-Sky Secondary Mirror Heater (S) is designed to wrap around the stalk to which the secondary mirror is attached, heating it and, by extension, the mirror itself. This indirect heating method is simple to install, does not require complex modifications, and is highly effective in preventing dew formation.
Suitable for a wide range of Newtonian telescopes, including models from Sky-Watcher, Celestron, Meade, Orion, and others, this heater is an indispensable tool for avid astronomers.
How It Works:
• Efficient Heat Transfer: The heater wraps around the secondary mirror’s stalk, heating the mirror holder mount. This mount then transfers the heat to the mirror, ensuring it remains free of dew.
• Minimal Heat Loss: Special production technology ensures that the maximum amount of heat is directed towards the mirror surface, minimizing losses to the atmosphere.
• Discreet Installation: The thin power wire can be neatly concealed within the secondary mirror mount, maintaining the telescope’s aesthetic and functionality.
Key Features:
• Wrap-around Secondary Mirror Heater (S) for mirrors on 1.25-inch stalks.
• Power Specifications: 12V DC supply, 2.4W power consumption, 0.23A current draw.
• Enhanced Performance: Directs maximum heat to the optics, ensuring effective dew prevention.
• Hand-assembled Quality: Each heater is meticulously assembled by hand, ensuring superior quality control.
• The Wrap-around Secondary Mirror Heater product line is suitable for most factory-made Newtonian telescopes from Sky-Watcher, Celestron, Meade, Orion, and others. Customers just need to select the heater of the appropriate size.
Optimal Performance with R-Sky Controllers:
Pairing this heater with an R-Sky controller allows precise adjustment of the heating power, preventing the optics from overheating and conserving battery power. This combination offers the best results for keeping your secondary mirror clear and your observations uninterrupted.
Invest in the R-Sky Secondary Mirror Heater (S) for a reliable, high-quality solution to dew prevention. Ensure your Newtonian telescope performs at its best, no matter the humidity.
