1.Este binóculo inclui alguns acessórios, nomeadamente tripé? 2. Dispõem de algum binóculo com capacidade de ampliação superior a 25? Obrigado. Amadeu Montrond Pires Monteiro
O tripé é um acessório separado. Seria necessário um tripé de cabeça de vídeo com uma capacidade de carga mínima de 6 kg. Não há binóculos acima de 25x, eles devem ser telescópios terrestres, mas todos têm visão monocular, exceto a Swarovski BTX
