Oh ? Maybe I can help there. For model building a good signal to noise ratio can be easily reached with strong binning, like 3x or 4x. And downscaling the image as well, I've tried up to 6x downscale and found 4x donwscale works well for my setups (F/12 and an F/5.4 systems). With this exposures of about 4 seconds suffice.
This confuses me. Do you think something got removed from MW4 or from Ekos ?
