DSO Planner app extensively supports data import and export operations using the dedicated DSO Planner text format. Any list with objects, notes, locations, telescopes, or eyepieces can be exported into the human readable text file, shared, using other applications, and imported back into DSO Planner either into the same module, or other module.

  • Export — Export current list data to a text file on SD card, using the DSO Planner text format.
  • Import — Import data from a text file in DSO Planner text format. When importing objects into the Observation List or Observation Notes list, you need to specify whether the source file is yours (exported by your own copy of the app) or someone else's (prepared manually or on other Android device with DSO Planner installed). That is crucial for most correct and optimal import of the data. When someone else's data is imported into the Observation List - there will be temporary objects created if the data does not contain reference to internal databases (if it does, permanent objects are made. This is the case when you import someone else observation list which contains only objects from internal catalogs). When your own file is imported permanent objects will be created, provided that the database objects being imported still refer to the existing objects (and weren't removed from the device).

Note: Understanding that feature, you can export a list of existing objects, then correct the text file in text editor, and finally, pretend that the list being imported us not yours, thus creating temporary objects which will be treated as self sufficient thus retaining any editions you've made intact. E.g. you can add a known current angular size of a comet that way and have it displayed on the star chart.

  • Paste — Paste objects from the Android clipboard. DSO Planner will try to interpret the text in the system's clipboard buffer as representation of object(s) data in DSO Planner text format, and if successful - insert them into the list or database.
  • Share — Standard Android OS media object Share option. The third party application (such as Gmail, Evernote, etc.) will receive a text bundle in DSO Planner text format to deal with. Note, that Android share function has a size limitation, thus you cannot share more than about 300 objects at once.

DSO Image

This module shows object images (Figure 15). There is an internal image database that has images for almost every NGC object (7840 images) from the famous NGCICproject.org website. Also you can add any number of new images for your own user database objects, by creating a custom database with multiple custom fields of "Image Path" type in it (See the typical Use Case description for more details on exactly that procedure).

DSO Image screen is commonly available from the Context Menu of any list of objects, such as the Observations Lists module, Object Selection module, and the View Database module. The Details screen will show the dedicated "Image" button if selected object has any images attached.


  • In case there are several images for an object available - you can switch between them by flicking the screen up and down.
  • Use pinch to zoom gesture to change the image scale.

Global Search

The Global Search module looks up for a specified string in the name of objects from all of the object databases available in DSO Planner, including the Observation Notes database (object name and notes text), and the Star Chart module layers (in the object names, but excluding the USNO UCAC4, due to its enormous volume). This function (Figure 16) could be invoked from any place by pressing Android OS "Find" button, if it is available on the device, or using the Main Menu of Object Selection, Observations Lists and Star Chart.


You can use the following string format to search for objects:

  • M1 — Messier
  • m 1 — any register, spaces
  • NGC1952 — NGC
  • ngc 1952 — any register, spaces
  • alpha and — bayer designation, constellation short name
  • alpha andromeda — bayer designation, constellation full name
  • alpheratz — star name
  • 21 and — flamsteed designation
  • 21 andromeda — the same as above
  • MCG+07-02-016 — M31 in different designation
  • CGCG535-017 — M31 other designation
  • tyc 1179-1775-1 — Tycho-2 layer stars
  • pgc1662164 — PGC layer galaxies
