Eyepiece filters enhance contrast, reduce glare, and improve the visibility of celestial objects by selectively filtering wavelengths.

A diagonal is a mirror or prism that bends the light path, allowing for comfortable viewing angles, especially when the telescope is pointed upwards.

A focal reducer decreases the focal length of a telescope, providing a wider field of view and shorter exposure times for astrophotography.

A solar filter blocks the majority of the Sun’s light, allowing safe observation of sunspots, solar eclipses, and transits without damaging the eyes or equipment.

A dew shield prevents the formation of dew on the telescope lens or mirror by insulating the telescope and reducing temperature gradients.

A motor drive compensates for the Earth’s rotation by moving the telescope at a steady rate to keep an object centered in the eyepiece.

A Barlow lens multiplies the focal length of a telescope, effectively increasing the magnification of the eyepiece used.

A finderscope is a small auxiliary telescope mounted on the main telescope that helps in pointing the main telescope to the objects.

Vibration suppression pads are placed under telescope tripods to dampen vibrations from the ground, providing a more stable view.

Counterweights balance the weight of the telescope and accessories to ensure smooth and stable movement of the mount.

A power supply unit provides consistent electrical power to telescope accessories such as motor drives, computers, and cameras.
