| Nachos (OP) User ID: 57537775 Australia05/01/2014 01:27 PM Report Abusive Post Report Copyright Violation | You'll need something more sensitive than a security camera to image stars. Ideally you need a camera capable of longer exposures than general commercial models. Quoting: Anonymous Coward 30217411 well i don't mean nasa quality, just something in HD that doesn't make the stars look like white blobs. just sharp clear dots i guess.

Thanks for that link. I doubt if it's anything even vaguely like a security camera, and probably a lot more expensive. Even for low quality (i.e. not NASA quality) you'll need long-ish exposures and/or a high-sensitivity CCD, otherwise you just won't see stars. Most commercial off-the-shelf cameras won't let you set long enough exposure times. |

| Anonymous Coward User ID: 57613953  Romania05/02/2014 07:16 AM Report Abusive Post Report Copyright Violation | I wish there was one, I was thinking about putting one on my roof with Infrared just to randomly look at the sky while im inside. But realistically you need an expensive apochromatic refractor with a HD cam hooked up to it to see anything clear outside the atmosphere. |

And wont know what it was where it was where it has been. Its like hooking up some binoculars at the disco rave  |
