After an actual test using my Hero 4 Black, I retract my comment above. Not only is this possible, it doesn't look half bad! I ran for two hours just out in the parking lot here in town - it's not even very dark here, and I was able to see stars moving in the resulting time-lapse! If you went someplace nice and dark, I think it might actually look pretty ...

The GoPro Hero 4 has a maximum ISO of 800 and a longest shutter of 30 seconds. These are the settings you'll want to use to get the most visible image in low light. They are available with Protune turned on. ISO 800 is supposed to be the default, but make sure it is set to 800. If those settings don't help, you can try and adjust the Exposure Value ...

I'm not intimately familiar with the go-pro. I took a quick glance a the contents page and noticed there's an option for multiple exposures. To accomplish that you'll need something with which to track stars. Generally that requires an expensive equatorial mount tripod for astronomy telescopes There is a cheaper way. Use your favorite search engine and ...

In DPReview's tests (see the "Continuous mode" section), they were able to get a shooting rate of 2.5 JPEGs per second (or 1.4 RAWs per second) even in "buffer full" mode, which is the rate achievable for essentially indefinite shooting. Or put another way, you should be able to shoot a frame every 0.4s for ever - at least until your card fills up anyway. Do ...

The maximum frame-rate is quoted for the internal buffer, so you wont get enough frames for much of a time-lapse. However, if you intend to produce a video, you can shoot for much longer by lowering the resolution. 8 and 4 MP are more than is needed for full 1080p HD and therefore will give you lattitude when producing a time-lapse for anything other than an ...

The six frame limit of the buffer is for RAW files, but 22 frames for JPEG. That shouldn't be a problem is you're shooting 1 fps in JPEG, but 5 fps could be a different story.

I've been having good luck with Sequence (for Mac): https://itunes.apple.com/us/app/sequence/id572525913?mt=12 I've so far only used its more basic capabilities.

As a warning to anyone thinking of buying a USB battery pack, don't -- my NEX goes into USB mode when I plug in a USB cable, even if it's a charge-only cable. Which means that it doesn't let you take photos -- the entire UI is replaced by a "USB" indicator. I tried changing the USB mode from mass storage to MTP to auto, to no avail.

What would be easier to do accurately is to have a system that combines a timing function with a system that gives an index signal at the start of a revolution and then series of pulses indicating rotational increments. This is easy to do in a number of ways. Use of an Arduino or similar could see the core part implemented for under $10*. Once you have the ...

What you want to do should actually be possible. First of all, you'll want to download the Canon SDK (Software Development Kit) from http://www.usa.canon.com/cusa/consumer/standard_display/sdk_homepage. Since you appear to be in Europe, your page is http://www.didp.canon-europa.com/ (found from the Canon USA page linked above). It indicates the SDK is ...

As of October 2014, Olympus has announced full USB tethering support for their OM-D E-M1 micro four thirds camera. Olympus Capture, the application that is announced, offers full control of the camera's functions. Panasonic's DMC-GH4 (also a micro four thirds) is supported by a far simpler USB tethering application.
