Deep Sky Browser [iPhone]

"FOR AN INCREDIBLE ON-THE-GO REFERENCE DSS BROWSER (now Deep Sky Browser) IS THE BEST.
This app gives you access to the Digital Sky Survey with more than 45,000 celestial objects only a click away… This is a great app for planning a night of observing." - Raymond Shubinski, Astronomy, August 2011.

Deep Sky Browser is a tool that allows browsing Digitized Sky Survey (DSS) images of various celestial objects. Deep Sky Browser also shows additional information for the selected object based on the observer's location.

Now it also functions as Digital Setting Circles. Just connect it to Astro Devices' Nexus or one of supported encoder interface boxes, do a two star alignment and Deep Sky Browser will show where to move the telescope to locate the selected object. Or use it with Nexus and ServoCAT for full GOTO functionality.

Deep Sky Browser is an invaluable tool for observations planning and identifying objects at the eyepiece.

The images are loaded from a DSS server and cached automatically. The built-in database of Deep Sky Browser contains in excess of 51,000 objects from popular catalogues: Abell Planetaries, ARP, Caldwell, Collinder, ESO, Herschel, Hickson Compact Groups, Messier, Index Catalogue, King, LBN, Minkowski, Markarian, NGC, Sharpless, Stock, Trumpler and UGC.

Object lists can be adjusted to only show objects that have magnitude brighter than the specified magnitude. Image field size can also be adjusted.

Deep Sky Browser also displays the current position of the selected object in the sky that is updated in real time. Additional information is also displayed for the selected object:
- Rise time
- Set time
- Transit time
- Today's visibility graph
- Yearly visibility graph
- Page number for Uranometria 2000, 2nd edition
- SIMBAD id
- surface brightness

Proper 'night mode' can be activated during the night observing.
*Please note that an Internet connection is required to download DSS images.
