As you may have noticed I have taken to sitting on hill tops in the dark taking photographs of the stars. So far so good, however one of the classic images is 'star trails' where a (very) long exposure is made, preferably including Polaris, the North Star.

I have a remote, the Nikon ML-3. However it has no provision to make 'bulb' exposures, I checked out the D300s User Manual before I went out, believing I had a way of making long exposures in 'bulb' without a remote, by latching the shutter release, I had misunderstood the manual. The wording is somewhat ambiguous and I read it too quickly. Net result, no images tonight, except numerous of the interior of my car, while I was trying to actuate the latching 'bulb' exposure. I now realise it doesn't latch.

I have checked out the Nikon website and found theres various options:

I somehow suspect what I need will be very expensive, so I went looking for alternatives...

http://www.ebay.co.uk/itm/DC0-YP-870-Wireless-Shutter-Timer-Remote-for-Nikon-D810-D800-D700-D300-10-Pin-/161721652457?hash=item25a75c94e9:g:xi0AAOSwl8NVa8qS

I am a bit torn, in the interests of reliability and simplicity I would like hard wired ten pin remote which latches the 'bulb' shutter, on or off (latching so I don't need to hold the button in for hours).

On the other hand, it could be useful to have wireless (not IR because it can be more fickle) radio control, but it must be able to make latched 'bulb' exposures, or better yet, self-time much longer exposures up to say, 8 hours?

Given the eBay item I have given the link for is Chinese, the description is somewhat cryptic, I am far from sure this remote will do what I want.

Can anybody suggest an inexpensive way to achieve what I need please, using a soldering iron and Dremel if need be. If I knew the pinouts I could possibly make up a bit of wire with a switch to simply switch the shutter on or off. JK?

I do have an old ten pin radio control remote which I took apart a long time ago to try to make a sensor switch to activate the camera by a beam but not sure where it is right now. I don't remember it having a latching release for 'bulb' though.
