Deep Sky Browser

(formerly DSS Browser)


Deep Sky Browser is an iPhone/iPod touch/iPad application allowing browsing Digitised Sky Survey images of various celestial objects.

The images are retrieved from a DSS server and cached automatically so you do not need to download them again. The built-in database of Deep Sky Browser contains in excess of 45,000 objects from popular catalogues: Abell Planetaries, Collinder, HCG, Herschel, King, Minkowski, Markarian, Sharpless, Stock, Trumpler.



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

The image size can be customised to show different sky field sizes:
- Actual object size
- 5' x 5'
- 10' x 10'
- 30' x 30'
- 60' x 60'

You can select images from different Digitised Sky Surveys: DSS, DSS1 Red, DSS1 Blue, DSS2 Red, DSS2 Infrared.
Deep Sky Browser can run in 'Night mode':
