United StatesDSO Planner 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 provides an opportunity to create any number of user own object databases. DSO Planner boasts the largest star catalog among all Android astronomy applications (USNO UCAC4, 113 mn stars). The application excels at creating observation plans on the fly, has powerful note taking capabilities, PushTo and GoTo support and night (red) mode.
Before installation please make sure that you have at least 2 GB 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 2 GB free on your internal SD card!)
+ Star catalogs. USNO UCAC4 (full star coverage to 16m, 113 mn stars), Tycho-2 (2.5 mn stars), Yale bright star catalog (9 000 stars)
+ Deep sky catalogs. NgcIc (12 000 objects including Messier, Caldwell and Herschel 400 objects), SAC (Saguaro Astronomy Club database, 10 000 objects), UGC (13 000 objects), Lynds dark and bright nebula (3 000 objects), Barnard dark nebula (350 objects), SH2 (300 objects), PK (1 500 planetary nebula), Abell cluster of galaxies (2 700 objects), Hickson Compact Group (100 objects), PGC (1 600 000 galaxies)
+ Double Star catalog. Brightest Double Stars (2 300 stars), Washington Double Star Catalog (120 000 stars), double stars from Yale catalog. Info Panel with PA and separation for each component.
+ Comet support. Orbital elements of around 700 observable comets could be automatically updated via internet
+ Minor planet support. Database of 10 000 brightest minor planets
+ 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
+ Object contours. Ellipse in real dimension and orientation
+ 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. Easily track observed and remaining to be observed objects with note taking tool
+ 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.
+ 2 visual themes (bright and dark)
+ Powerful share/export/import capabilities (of databases, observation lists, notes)
I have tried several planetarium style apps but nothing so far that comes close to DSO Planner Pro. It comes with a learning curve but the time spent is very well worthwhile. I can now work at the eyepiece of my scopes with a plan of the nights observation and use the app to get a clear representation of the sky. Also many inbuilt databases and the ability to add your own plus ability to display the sky with only those objects that you can see with your equipment. works with setting circles.
For visual observers using manual mounts, DSO planner deservers a serious look. What it lacks in eye candy and animations it makes up for in thoughtful features. Like a star map that doesn't move when set your phone down to adjust your scope. Like a visibility score that can help you target objects appropriate for skies and equipment. Like the telrad display that can be calibrated to an alt azimuth mount. It's true that you need to RTFM to get the most out of it.
Magnitude limit appears to be working. The app looks mostly driven by field of view. Although the search function Is improved over previous versions. I also like the extensive data basses and access it provides so I remain a fan for the most part. One of the better rated apps that can get the job done.
Great! Really appreciate your job! Best planner, with simple "for human" interface, and lots of catalogs. Hope in future WiFi connection, for Synscan on my DOB will be available;) Thank you very much!

This is more a question than review. after purchase I still get the 'Sorry this function is only available in paid editions.' How do I fix this? One thing I dont like is the notes function. When selecting a Messier object it lists them with their NGC designation. Needs to list both.
Minor fixes and improvements.
