Pros & Cons:

Image viewer of stars and deep space objects. Excellent index of stars and deep space objects. Bookmarks.
No solar system objects.

Our Review: (aka WikiSky) is an online viewer utilizing your browser. The images here are in color and come from several sources, e.g. DSS2 all Sky Survey, IRAS Infrared Sky Survey, and user uploaded photos.

The index also found every star and deep space object in my test sample. Oddly it also indexed the location of the planets but no images were available.

The website allows one to upload an image for display in the catalog. Some of the views have many layers of images each opaque to the ones beneath. Left clicking on an area with one or more images opens a popup window where you can select the desired image for viewing. When zoomed out a bit the layered images look a bit odd.

The service requires an Internet connection and browser. was reviewed by on
