Trust Losmandy for exceptional robustness and high build quality. Losmandy equatorial mounts are best-in-class. They are designed for the astronomer who demands unyielding performance from his equipment.

The Losmandy GM8 is great for small-to-medium sized instruments, for visual observation and astro-imaging.

Note on price: Due to the weight and sizes of the various shipping boxes, these mounts are expensive to ship from California. Please allow an additional $155.00 USD (plus applicable tax) on top of the price listed above. We will add this charge to your order when we process your payment.

Note on power supply: If you are powering from the AC mains, we recommend Losmandy's 15 volt power supply. This will ensure reliably sufficient current that a 12 volt supply may not quite provide.
