You can't turn it all the way off on the 4040, but you can manually dial it down to Low.
It appears to be one of a dozen prototype cameras that were built in September 2011. I don't know the history of it, but we do have test data...
Make sure the camera is showing up in the Device Manager. Error 27 indicates that it can't open the system driver.
Production boards have been built, and we're working on finishing up the firmware.
Totally agree with Colin - just use our back focus calculator spreadsheet. It's accurate to within camera tolerances (there can be some very...
Yes, and we sell adapters for that purpose. https://diffractionlimited.com/product/filter-insert-36mm-1-25/
You can try changing the fan speed. If the vibration drops then you are indeed hitting a resonance. Also you could try a sleeve bearing fan...
I would use High Gain StackPro. This provides good dynamic range and low noise. You could also use High Gain if you don't require large...
Use a minimum exposure time of 0.015 seconds.
There's no reason I can think of that a 0.015 second exposure would work, and a 0.014 second exposure would not. That's pretty weird....
Should be fine. Very typical configuration.
Your camera may need service. Let us know if you need RMA instructions. One thing to check first - if you've swapped adapters on the front at...
Beautiful! Keep 'em coming!
I tried subtracting the two images... the dim one makes a pretty good dark frame for the bright one. This suggests that the camera took the...
I'm not really seeing an increase in noise on one frame compared to the other, doing a simple dark frame subtraction. Images can often look...
I can't use images processed by PixInsight; it does weird scaling to them. I wanted a raw dark frame. Also, I recommend reshooting your darks...
Changing the weight distribution of the instrument can affect the polar alignment due to flexure, especially if your mount is at (or beyond) its...
I'm thinking maybe the camera's logic failed to synchronize properly with the image sensor data stream upon startup. Very weird... we've not seen...
