Nikon1, I got the longest (50 feet) wire I could find. I will search further and see if I can get a much longer one. That should essentially get us to where we need to be. The only piece I don't have insight into is the material of the two buildlings that the signal will need to go through.

I've successfully used the 50 foot extension and the remote trigger through a few concrete walls at my office.

The 'remote trigger mod' I referred to is detailed here on the site:

<<To actually figure out the Correct settings, i would advise you to do at least two tests before shooting anything critical. >>

So, next up is to test these various settings in some sort of controlled way. I'm going to create a spreadsheet with different settings and test shoot the model rocket nozzles and see what I come up with.

There is no way to test shoot the actual items during a test as the are 'fire once' types of objects.

My hope was that I could send this camera to the facility with someone who is not familiar with photography but that is out of the question. I'm afraid I may have to travel to shoot these tests myself.

Thanks for the help. I'll post my test shots as soon as I get them.

Hi all.

First, thank you for the help on the forum already.

I would like some advice for my use case. I will be filming a rocket nozzle test and want to focus on the nozzle, not necessarily the 'flame' at the end of the nozzle. The nozzles will be between 12 and 36 inches long.

I have a Chronos 1.4
A few mods have been done to it so far:

1. The SSD mod.
2. The remote mod.

For the remote mod, I don't think the 80 meters is going to be enough, so I got a 3.5mm to RCA cable that is 50 feet long. I'm hoping that extra bit will allow the trigger to work where it's needed. (The camera will be ~200 feet away and the trigger will need to go through a few building walls as humans aren't allowed near the test stand.)

I plan on getting a few Estes model rocket nozzles to do some testing with.

I'd love some advice from those with experience on settings that might be good for me to start experimenting with. The gain seems a bit limited as I think negative gain might be necessary?

Any advice for either:
1. Remote trigger from long distance
2. Rocket brightness mitigation

Would be appreciated.

Thank you.

*Unfortunately I won't be able to share the images that I capture from the actual nozzle testing. Sorry!

This wireless trigger is not available.

Would this be a replacement for that?

You can use any normally open switch connected to the BNC connector on the camera as a remote trigger.

Ben Krasnow (Applied Science) and I have both successfully used the Pixel TW283 remote trigger. Any variant will work, you won't be using the included cable. You need a 3.5mm male to BNC male adapter to connect it to the camera, this is most easily done with a 3.5mm to RCA cable, followed by a RCA to BNC adapter.

This trigger has one bug, if you mash the shutter button quickly it will miss the press, you need to press the button slowly through its half-pressed state to fully pressed. Other than that it works well. This is a problem with the trigger itself, not the camera.

Thanks Mostafa. Formatted it, I'll capture some new footage tomorrow and test saving.

I printed the cage, got an ssd and the correct cable. When I go into the settings, the camera does not recognize the ssd. I'm not sure what I'm doing wrong here. Any suggestions? Brand new user....

I WAS able to get some footage of a match lighting, but couldn't save it!

Thanks.
