Flats with 383L
« on: December 14, 2020, 02:11:47 am »
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.

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
