You need the nightly (beta) release: stellarmate.com/support.html?view=kb&kbartid=5

So I've just switched to the nightly build but when I run gphoto2 -v afterwards it is saying I am on version 2.5.9

Am I looking at the wrong thing here or have I screwed something up...?

I've tried taking an exposure but still no joy., it keeps switching the port to ttyUSB0 rather than ttyUSB1 (although that changes each time.

Thanks

did this go anywhere as i have the same kit and same issue!

Not that I'm aware of but I haven't tried for a while as life got in the way and there haven't been many clear nights recently.

Still no progress with this?

I've just done a full upgrade again and I'm still getting the same problem. When I set the shutter device to /dev/ttyUSB1 as soon as I connect it changes to USB0 and then won't control the shutter release relay.

I'm on the nightly build but it still shows gphoto2 as version 2.5.9

I need this too as I want to press my modded D5100 back into service. Thx.

I have built a driver that enables me to use my Sony A57 (no remote/usb) in combination with a FTDI bulb cable and a FlashAir WiFi card. This driver is very easily modified for your camera. Actually, since the D5100 and A57 have the same sensor, I think you just need to delete the FlashAir components.

This driver lets me auto focus and frame on a DSLR with no usb tether capabilities. It is still a work in progress, but you are welcome to try it

If you wait a week, I will make it more generic, with FlashAir being optional.

Just wanted to say my D5100 w/relay works just fine using gphoto. This is with Astroberry, if it matters.

Great! Thanks for this! I'll give it another go this week. I'm on a D5000 rather than the D5100 but it shouldn't be too different... I'm using Kstars rather than gphoto but it is the gphoto Nikon ccd driver that kstars uses. I'm using the KM tronic relay for the shutter release though so hopefully your driver will work

Thanks again. I'll report back once I've tested it

Hello! Please tell me how to install this driver?

I am using Nikon D5100, with a homemade shutter control cable based on the ch-340 chip. Long shutter speeds work, lifewiev does not work. If you use a usb connection, everything works, aging is not more than 30 seconds. What could be the reason?

It's still in early development, and very specific to my setup (I have hardcoded folder names); I have yet to test it under fire. I can see it is useful to many people so I will keep working on it over the next few weeks. I recommend you wait a week or two. If you really want to crash EKOS, try this:

indiserver -v -p 8000 indi_sony_a57

Then in EKOS set it to remote: localhost port: 8000

I will put specific instructions in GutHub soon.
