Hi Jerry
Can you post a picture to see these strange artifacts !?
For the length in sec. depends on the brightness of the panel with which you do the Flat. But on the net you can find a formula for what FWC must be.
A saturated exposure at 50-75% of the possibilities of the CCD
Large Format / Flats with 383L

Looking for data on flats for the 383L.  What is typical exposure length for flats with this camera in LRGB?

I am getting some strange artifacts at exposures under 5 seconds and would like to know if this is typical for this camera.

I have just had exactly the same experience!
I can't recall why I upgraded the Atik software, but I couldnt connect using the  new native drivers (in Prism). I therefore gave the ASCOM drivers a go... However, very high background ADU (3,500 - 5000) ensued (in a spectroscopy session - its obvious here as most of the image is background).
I have rolled back to the 'legacy' software now. I am sticking with thsi as long as possible!

That's what I was thinking! So, I did a LRGB synthesis run in Nebulosity combining the above mono image with a 15 minute RGB stack taken this week with my Horizon OSC. It really brought out the fringe nebulosity when compared to the RGB alone. Had to be careful not to emphasize the mono channel too much as it would blow out the Trapazium core.
