Archery scope and accessories

An optical sighting assembly comprising:

• an optical scope body comprising a sighting bore;
• and
• an accessory comprising a light source and configured to detachably attach to the optical scope body due at least in part to a magnetic force between the optical scope body and the accessory;
• a lens attached to the optical scope body;
• and
• a fluorescent aiming point attached to the lens,
• wherein the light source is positioned in the accessory such that when the accessory is attached to the optical scope body, the light source is configured to illuminate the aiming point through a non-solid medium, and
• wherein the light source is configured to receive an electrical current from the energy source.

An optical sighting assembly comprising:

• an optical scope body comprising a sighting bore;
• and
• an accessory comprising a lens cartridge and configured to detachably attach to the optical scope body due at least in part to a magnetic force between the optical scope body and the accessory;
• wherein the lens cartridge comprises a keyed surface and a lens receptacle,
• wherein the keyed surface is configured to mate with the optical scope body in a predetermined orientation, and
• wherein the lens receptacle is configured to receive a lens.

An optical sighting assembly comprising:

• an optical scope body comprising a sighting bore;
• and
• an accessory comprising an alignment ring and configured to detachably attach to the optical scope body due at least in part to a magnetic force between the optical scope body and the accessory;
• wherein the alignment ring comprises magnetic extensions, and
• wherein the magnetic extensions are configured to extend within the sighting bore of the optical scope body and provide at least a portion of the magnetic force between the optical scope body and the accessory.

An optical sighting assembly comprising:

• an optical scope body comprising a sighting bore;
• and
• a lens cartridge configured to be detachably installed in the sighting bore at a predetermined rotational orientation;
• wherein the lens cartridge is sized to retain a first lens,
• wherein the lens cartridge is replaceable by a replacement lens cartridge configured to mate with the sighting bore,
• wherein the replacement lens cartridge is sized to retain a second lens, and
• wherein the lens cartridge is sized to be incompatible with the second lens and the replacement lens cartridge is sized to be incompatible with the first lens.

An optical sighting assembly comprising:

• an optical scope body comprising a sighting bore;
• a lens cartridge configured to be detachably installed in the sighting bore at a predetermined rotational orientation;
• a lens retained within the lens cartridge;
• a fluorescent aiming point attached to the lens;
• a light source attached to the optical scope body and positioned to illuminate the aiming point through a non-solid medium when the lens cartridge is installed in the sighting bore;
• and
• an energy source attached to the optical scope body and configured to provide an electrical current to the light source.

An optical sighting assembly comprising:

• an optical scope body comprising a sighting bore;
• a lens cartridge configured to be detachably installed in the sighting bore at a predetermined rotational orientation;
• and
• a light pack comprising an energy source and an LED,
• wherein the light pack is magnetically attachable to the optical scope body,
• wherein the light source is positioned to illuminate the sighting bore of the scope body when the light pack is attached to the optical scope body, and
• wherein the energy source is configured to provide an electrical current to the light source.
