Astrophotography Accessories

• USB-operated cooling fan for StarSense Explorer 10” and 12" Dobsonian and other Dobs and reflectors with a compatible fan mount
• Speeds up the cooling of the primary mirror to the ambient air temperature resulting in crisper, better-focused views in less time
• Mounts directly to the rear cell of the StarSense Explorer 10” and 12" Dobsonian telescope
• Integrated storage clip to secure the USB cable when not in use

• Enhance imaging of nebulae with your 8” Rowe-Ackermann Schmidt Astrograph (RASA) by blocking light pollution, improving image contrast, and darkening the sky background.
• This filter transmits only the key Hα-Hβ-OIII wavelengths from emission nebulae, providing high contrast that makes them “pop.”
• This filter selectively blocks wavelengths of light from sources of light polluted skies and natural sky glow.
• Unlike similar filters with narrower bandpasses, this filter was engineered specifically to work with RASA’s fast F/2 optics.
• Fits into the 8” RASA’s integrated filter mount, maintaining peak optical performance.
• Optically flat surfaces free of defects, constructed of Schott glass with anti-reflection coatings.

• Compatible With E-3 Type Remote Control Terminal
• Electronic Shutter Release Cable
• Connect Your DSLR Camera to Sky-Watcher Computerised Mount
• 5 Years Australian Manufacturer Warranty
