| The TeleVue #13TRA adapter lets you connect a 35mm or digital SLR camera to a TeleVue imaging system refractor using an optional standard camera T-ring. It mates with the other optional (but necessary) imaging system accessories listed below. The #13TRA allows 35mm and digital imaging with following TeleVue IS (Imaging System) scopes: the TV-102iis, the NP-101is, and the NP-127is.
Due to the restricted size of the inner diameter of a T-ring, this adapter is recommended for use with digital SLR cameras having an APS size (30.2mm x 16.7mm) or smaller imaging chip.
In addition to this #13TRA and an appropriate camera and optional T-ring, imaging will require one of three combinations of some of the following accessories (which combination is used depends on the type of photo application – see the system chart feature image below):
the #1360 Large Field Corrector or the #1362 0.8x reducer,
a #13T025 0.25” spacer,
a #13T037 0.375” spacer,
a #13T050 0.5” spacer,
a #13T100 1.0” spacer,
plus the imaging system adapter supplied with the TeleVue telescope.
The system chart feature image below shows the required order in which the #13TRA and the other optional accessories should be assembled for proper operation for 35mm imaging and two different types of digital SLR (APS-size chip) imaging. |
