How does one do very long exposures on the K200D, for astrophotography ?
I'm talking 10 minutes+ here.
The manual says it will stay open as long as you hold the shutter release, but that doesn't seem practical at all when you need to do it for that long, not to mention the camera shake.
I have the remote control also, but same issue - the manual says that in bulb mode, you have to hold the remote control button for the whole time of the exposure. That seems somewhat impractical too.
Also, I tried it with my made-in-china remote control clone from ebay, and it doesn't hold the exposure even if I hold the button. I suspect it doesn't keep sending the IR signal. This may be a problem of the clone.
Lastly, the manual also talks about cable release switch . Is there any way to do a long exposure that way without having to keep pressing a switch for a very long period of time ?
Ideally I would want to be able to use the remote - once to tell it when to start exposure, and again to tell it when to stop. Seems that could be implemented easily in firmware ... But it's not the way it's done right now.
I think I *could* teach my big sony RM-AV2500 universal remote control the IR code on the hard "volume" key, which would cause it to repeat the code when the key is held. And then use a brick or something on that hard key to hold it. But we are talking about a pretty big remote, about the same size as the camera. Not something practical.
