To display a Telrad™ Finder

Telrad Finder at a 10 degree field of view

 

A Telrad Finder is a unique Field of View Indicator because its field of view is not dependent upon a telescope optical system. However, TheSky6's FOVIs require that you define a telescope and eyepiece or detector to create a FOVI.  So, in order to define a Telrad™ FOVI, you must create a "dummy" FOVI (based on a telescope/eyepiece combination) and then modify its geometry.

 

  1. Click View | Field of View Indicators to display the Field of View Indicators dialog box.

  2. Click the Telescopes tab and then click Create.

  3. On the Create/Edit Telescope dialog box, enter "Telrad Telescope" in the description text box and then click OK.

  4. Click the Eyepieces tab and then click Create.

  5. On the Create/Edit Eyepiece dialog box, enter "Telrad Eyepiece" in the description text box and then click OK.

  6. Click the Create FOVIs tab.

  7. Click the My Eyepiece option and then select Telrad Eyepiece from the list.

  8. Select Telrad Telescope from the list and then click Add My FOVI.

  9. Click the My FOVIs tab.

  10. Select Telrad Telescope + Telrad Eyepiece from the list and then click Edit to display the Create/Edit Detector Geometry dialog box.

  11. Click Telrad from the Shape group. Change the Description to just Telrad and then click OK.

  12. Select the Telrad FOVI from the My FOVI list and then click the On option. Click Preview to automatically center the Telrad on the Virtual Sky.

  13. Click OK.

 

TheSky6, by default, zooms to a 12 arcminute field of view when the Preview button is clicked. The Telrad Finder is about 4 degrees across, so it's not entirely visible. Click Orientation | Zoom To | Finder 10° to see the entire Telrad Finder.

 

Click View | Status Bar, mark the Field Width and Visible option to display the current field width in the Status Bar.
