grade aluminum dovetail mounting base designed for large astronomical telescope equatorial mounts — lightweight, rigid, and easy to use. Key benefits Strength without bulk: Machined from grade aluminum alloy, the clamp weighs 431 g while delivering reliable structural support for heavy optical tubes. Stable, vibrationresistant hold: The reinforced dualbolt fixing system locks your dovetail securely in place to minimize vibration and preserve precise alignment during long observing or imaging sessions. Fast, flexible setup: Side screw holes plus a dovetail groove allow quick assembly and disassembly and accommodate common accessory attachments, so you can change configurations in the field. Built for compatibility: Engineered dimensions of approximately 88 × 88 × 28 mm and a redsilver finish make this base specifically suited to large astronomical telescope equatorial mounts. What it does for you Keeps your telescope steady during extended observation and longexposure astrophotography by reducing movement at the mount connection point. Speeds setup and teardown so you spend more time observing and less time fiddling with hardware. Provides a durable, corrosionresistant mounting surface that balances portability with strength. Technical details Material: grade aluminum alloy Weight: 431 g Fixing: Reinforced dualbolt system Features: Dovetail groove, multiple side screw holes Dimensions: Approximately 88 × 88 × 28 mm Finish: Redsilver Intended use: Designed to fit large astronomical telescope equatorial mounts Use scenarios Field stargazing: Attach your optical tube to an equatorial mount quickly at a darksite session; the lightweight base keeps your setup portable without sacrificing stability. Astrophotography: Maintain accurate alignment during long exposures; the dualbolt clamp reduces microvibration that can blur fine details. Club or classroom mounts: Easy to swap optical tubes and accessories between sessions while keeping a dependable, repeatable mounting interface.
