Svbony

• USB interface; plug into a USB power adapter; a portable charger; the USB cable makes lens warmer ideal for indoor and outdoor use;
• Temperature range; working temperature adjustment range from 25 degrees to 70 degrees to suit different weather environments;
• Fastener design; with handy fasteners; it can wrap around your lens or scope with security and is easy to adjust;
• Different length; liminate dew; fog; and condensation with our specially crafted lens warmer during cold weather photography;
• Designed with PWM Function, which can provide more accurate, energy-saving, efficient heating control, thus enhancing the performance and reliability of telescope equipments.

Note: This dew heater is suitable for SV503 70ED, SV48P, MK105, SV503 80ED, SV503 102 ED, SV550 80 APO

• Large prism design provides a wider field of view and ensures greater tracking accuracy.
• Adjustable prism height for precise alignment with different cameras and telescopes.
• Dual helical focuser enables fast and stable focusing, preventing star blurring due to inaccurate tracking.
• CNC-milled housing offers high robustness, withstands temperature fluctuations and deformation in outdoor use.
• Compatible with APS-C and smaller sensors.
• Supports M54, M48 and M42 threads for broad compatibility and quick setup.

• This dovetail mounting plate provides a platform for attaching the telescope optics tube to an equatorial mount. It is compatible with finderscopes, finderscope anchors, and equatorial mounts;
• Dovetail plates are made from extruded anodized aluminum, full metal aluminum alloy is used to ensure lightweight yet ultra-strong support;
• Dual dovetails nodal slide vertical rail along the length makes the mount equipment right where you need it;
• 1/4 standard thread adds threaded holes to connect other accessories, quickly switch from tripod to other usage scenarios;
• Installation method: The tube ring (sold separately) is bolted to the dovetail plate, and then installed into the dovetail groove on the equatorial head (sold separately).

• 2-in-1 design, can use offilter1.25" & 2" specifications on the market
• With strong the ability of double strong magnetic adsorption, it is more convenient and much easier to install or pull out the filter.
• Twelve M2.5 female threads are evenly distributed at the telescope end, supporting OAG fastening connections
• Advanced CNC integrated molding processing, quality assurance
• Lock screw on the side of it. The locking function is helpful on adjusting the tension to eliminate the gap, which is a double insurance for users.
• The filter drawer comes with the M42-M48 adapter To resolve the thread compatibility issue.

The Svbony SV193 combines two essential functions for ambitious astrophotographers: focal length reduction and field flattening. With a reduction factor of 0.8, it shortens the effective focal length of the SV503 80mm f/7 from 560 mm to approximately 448 mm, enabling a wider field of view and shorter exposure times—ideal for deep-sky imaging.

Technical Features

• Optical design: 3 elements in 3 groups, fully multi-coated for high light transmission and minimized reflections
• Connection: 2″ barrel with M54x0.75 thread for cameras; compatible with full-frame sensors
• Filter thread: Standard 2″ thread for integrating light pollution filters
• Housing: Hard-anodized aluminum, lightweight and durable
• Field flattening: Corrects spherical aberration and edge distortion for sharp star images across the entire field
