The mother of all starlight scopes! TVS-4A Upgraded to ABC tube assembly, which uses 3 40mm GEN1 tubes cascaded, for similar light amplification to GEN2, without the 'pixeling' of the microchannel plate tubes. Depot-rebuilt condition, with transit case, tripod, and battery adaptor for use with 4ea 'AA' cells. Great scope for astronomy, or surveillance around your evil lair :)
