A study of nonsensibilized astrophotoplates NT-1 used for photography of celestial objects with long exposures, based on emulsions with the quasi-T-crystals of silver halogenides is made. The photographic plates should be hypersensibilized with hydrogen before observations. They have a fine graininness and a high resolving power. Since 1991, they have been used at Pulkovo for long-exposure photography of various celestial objects with the Normal Astrograph (Pluto, the Pleiades, the Coma cluster and radio sources) and were compared with ORWO plates. |
