Yep, always in manual mode, there is no Wifi on it so thats fine, I've not tried the powersave features so will give that a go now I've got the external power supply for it

I'm starting to feel the same way... I've seen it work once though so I know it's possible unless that was a bug and it's since been removed haha.

It's very tempting to get the ASI Air or Stellarmate.. I plan to upgrade my nikon to the ASI16000MM in the future so it's good to know that there could be a way to get it to work on that if I buy the ASIAir earlier than the camera...

Thanks

Since I have a Mac and two USB ports I thought the AsiAir would be an inexpense test rather than put a more money into some other ‘cpu box’. For me it solved a lot of problems

Well I've asked in the ASIAir fb group and they have basically said it's not supported and not even offered to look into it so it doesn't fill me with confidence that if I bought it they would get it working for me... Gonna stick with Astroberry for now and keep trying to get it to work. I can trigger the shutter with a shell script but still cant get EKOS to do it for me

I've got a test script that activates the shutter with the following code...

Open shutter is echo -e "\xFF\x01\x01" > dev/ttyUSB0

close shutter is echo -e "\xFF\x01\x00" > dev/ttyUSB0

Is it possible to get EKOS to send this out to activate the shutter relay board...?

I wouldn’t take some FB or forum’s word for it based on my experiences here and the PhD2 forum. One can write Zwo directly at This email address is being protected from spambots.

To be clear, your saying PC command-line to camera works, but how to make Ekos issue commandline scripts? I don’t know about Ekos. I only have its guiding module working but w/o a camera working one can’t get more of Ekos to work, so no help on my end.

.... but doesn’t Nikon have a utulity? With my testing. I knew the camera was working cuz my Canon util and anoth guiding app worked. Besides command-line control do other apps on you PC control the camera?

Good plan, I'll drop them an email, thanks.

I am currently using an old PC laptop to control everything through APT Astrophotography Tool & PHD2. It works for the camera, mount & guide camera with no additional scripts.

I am trying to lighten the load by moving to a Raspberry pi running kstars/EKOS etc but this is the stumbling block...

So far I know I can control the shutter using a script so it works with this setup, it's just a case of getting EKOS/INDI to send the right 1's & 0's to the relay board to get it to work...

Well good luck w/ that Simon. This stuff can be very frustrating.

Who knows, maybe Zwo will have encouraging info; not sure what Astroberry costs....

Astroberry is free apart from having to buy your own Raspberry Pi. Its basically just an Ubuntu Mate OS with a few things pre installed like kstars EKOS etc that you can then connect to via VNC

curios to see if it will run your camera

I know it will... I managed to get it to work once, for one image, under testing in my house... Since then, nothing... Thats the really frustrating part about it! haha

I'll get there eventually though. At least I know the pi is able to control the USBrelay board properly now. It's now just a case of getting EKOS to do the same thing and I'll be golden and ready to build my all in one box for everything and add the homemade motorised focuser!

Hi guys,

I've been looking around here as I was running into the same kind of issue, then I'm posting my little bit of experience about it in case it could help someone in any way.

Basically I managed once (at first use) to get my D3300 capturing correctly without any extra shutter control device, but then when wanted to use it for real it was not working anymore (shutter not released / "failed to expose" issue).
I've then decided to go for a fresh install before to go for purchasing a kind of device mentioned here, and guess what...it's running properly at the moment (able to get any kind of capture, short and long exposure, FITS and native formats, etc.)

Setup
RPI2 Raspbian 9 / INDI 1.7.4 / indi-web
Laptop Ubuntu 16.04 / kstars-bleeding
Nikon D3300 / Standard Nikon DSLR Driver

No special costomization, just an install from scratch on both client and server, moving the reflex power mode from "medium" to "long", and putting it in Manual mode before wire.

Nothing really factual I assume...but a least it proves that it can work, and as also reported earlier, sounds like a damn bug somewhere.
