What looks like dead pixels on Epic MX

[Ryan W White]

Hello all,

I have recently purchased an Epic-MX. Last night I was shooting the full moon and decided to try out 1fps. I also slowed the
shutter to 1 sec. Looking at the image after it seems like there is a wide array of dead pixels when the camera is left wide open like this for long exposures.
all of these small dots of various color stay in place as the camera is moved. What is strange is they don't show up when shooting
at a standard shutter and frame rate. Does anyone have any ideas as to why this may be showing up?

I would venture to say it a product of not enough light. You could try black shading at that fps and see if it helps. The fact they don't move around is a little troublesome though. You should pull the lens, put the port cap on and see if they appear in the same positions with no light at normal frame rates/shutters. At the very least, that can help identify the issue locations as it can be hard to find them all with an image up.
