 As well as... They may not have the last word in various attributes normally considered important for general photography but are not critical for broad astro stuff, not telescope mounted.

They are fast and cheap with no frills. For occasional astro whole sky (as opposed to narrow field telescope mounted) photography they are ideal.

BUT being cheap it seems the sample quality can be iffy, good samples are said to be excellent but there are a variety of optical issues I have read about like out of focus at one side or not reaching infinity... Important for Astro stuff!!! :sssshh:
