I wanted to start a new topic about the Nikon D3400 entry level DSLR. I know there are many users of this camera, likely unmodified, that are getting into the hobby of astrophotography. I have found that this DSLR body is difficult to use for astrophotography and I think this is a good place for Nikon D3400 users to share their thoughts and ideas on the camera. I am unable to find an existing topic covering it so I am starting my own. This camera is a bit of an oddball in that it is not wifi compatible and does not have a utility or 3.5mm jack connection. It only has micro USB and a 'mini' HDMI port. The micro USB does not support any intervelometer device that I can find which makes this camera difficult to use as an astrophotography camera. You are ultimately constrained to 30 second sub-exposures and using a wireless IR shutter release remote which requires the user to stand next to the camera and monitor it at all times to make sure its taking pictures correctly. I am proposing using its IR capabilities to use an existing app and "IR blaster" to control the shutter. (For android users this is easy, there is an app readily available to do this. Check out this video.
However for iPhone users like me its not so easy. I found this app and I used this 3.5mm jack IR blaster that I was able to use to control my camera with over IR, only it is much slower than I would have wanted. For instance, the app allows you to enter a start time delay (time to elapse before the camera starts to take photos) and a time delay (time in between shutter releases) and a count (number of shutter releases.) When set to the 'time' setting, this will tell the camera to take x amount of exposures by adjusting the time delay setting, but the time in between exposures equals the same x amount of time. For instance: 1:00 sub exposure time = 1:00 in between sub exposures. This is the best solution I have come up with without spending the time to write a script to run an arduino or raspberry pi with an IR transmitter mimicking the nikon IR signal to control my rig. Anyone else have the same issue? This a general discussion of the Nikon D3400 in general as well so anything about the camera is welcome too.
Thank you all!
