DSO Planner Plus (Astronomy)

DSO Planner Plus is an astronomy observation planning tool with excellent star charting capabilities made by active and experienced amateur observers with a passion for visual observations. It has large integrated deep sky objects databases and star catalogs, and provides an opportunity to create any number of user own object databases. The application excels at creating observation plans on the fly, has powerful note taking capabilities, PushTo and GoTo support and night (red) mode.

Consider Pro Edition if you need more stars/PGC objects.

Before installation please make sure that you have at least 540MB of free space on your internal SD card to download application databases! (Note: due to Google Play rules this data cannot be moved to your external SD card - you must have 540MB free on your internal SD card!)

Famous Steve Gottlieb Notes attached to NGCIC objects

Custom catalogs. Unlimited capability to create fully searchable own catalogs

Cross-match names database. Search objects by less common names

DSS imagery support. Download DSS images of any sky portion into offline cache and overlay it on the star chart

Offline images. Integrated set of images of most NgcIc objects, opportunity to add own images when creating custom catalogs

Nebula contours. Contours of famous nebulae

Night mode. Fully red screen with red keyboard and menus

PushTo for dobsonian mounts with setting circles. Level your dobsonian mount and perform one star alignment. The app will automatically recalculate az/alt numbers to easily hunt the object

GoTo for Meade and Celestron controllers with bluetooth dongle

Unique visibility tool. Only objects that are visible with selected equipment in the current sky conditions could be shown on the Star Chart (for objects from NGCIC/SAC/PGC catalogs)

Planning tool. Filter any objects database by observer location, sky condition, astronomical equipment, time range of observation and object features (type, dimension, magnitude, minimal altitude, visibility and other fields of own custom catalogs). Remove duplicate objects when searching in intersecting databases. Create up to 4 observation lists. Track observed and remaining to be observed objects

Import tool. Import observation lists in Sky Safari and Sky Tools format. Use pre-compiled Night Sky Observer Guide observation lists.

Note taking. Take text and/or audio notes

Observing places. GPS, manual coordinates, custom lists. Database with 24 000 cities worldwide

Equipment. Keep track of all your telescopes and eyepieces. Use them for object visibility calculation and star charting. Use 500 popular eyepieces database

Twilight calculator. Calculation of the full darkness for a current night and for a month ahead.
