Equipment Database

The program supports two user databases of optical instruments: telescope database and eyepiece database. This data is used for [node15.html#object_vis visibility] calculation and for depicting [node5.html#sky_chart_ep_fov eyepieces field of view] on the Star Chart.

Select necessary telescope before [node3.html#dso_selection filtering] objects based on their [node15.html#object_vis visibility] in either [node10.html#common_conditions Select Conditions] or [node6.html#astro_eq Settings].

[node5.html#sky_chart Star Chart] draws field of view for each selected eyepiece of the selected telescope; [node7.html#details_screen Details Screen] shows object visibility for them.

The list shows names and brief description of your telescopes, on the right side there are checkboxes to indicate which telescope is currently active (Figure [#fig:telescope_list_screen 11]). Press on checkbox to make a new selection.

Add new telescope button helps you add a new telescope to your telescope list.

Context menu

  • Edit. Edit telescope parameters
    • Name. Telescope name
    • Aperture (mm). Telescope aperture in mm
    • Focal length (mm). Telescope focal length
    • Pass through (%). The amount of light passing through the telescope. 70% is a usual benchmark for reflectors
    • Short text note. Brief comment if required
  • Assign Eyepieces. Assigned eyepieces are used for Star Chart eyepiece ring drawing and visibility calculations. An eyepiece may be assigned to several telescopes
  • Remove. Remove telescope from the list

The list shows names and brief description of your eyepieces (Figure [#fig:eyepiece_list_screen 12]). Add new eyepiece button adds new eyepiece to your eyepiece list. When adding a new eyepiece you could either enter your own eyepiece parameters or select an eyepiece from the database with more than 500 popular eyepieces data.
