Flats on a Budget in Sharpcap 3.1 Pro "Revised"

A simple explanation and procedure to make flats in order to remove dust motes and vignette using Sharpcap 3.1 and a USB drafting tracing board. REMEMBER to shoot different speeds of exposure to get your flats just right. If your Flats are turning out RED/Blue/purple but not green,after you calibrate your light in Pixinsight, the cause is your LCD/light panel/drafting board, it took me a long time to track down that problem, it appears those LCD panels are not true natural light sources hence the strange color side effects, at this point you could do Dawn , morning daylight flats which will give you the nice dark Green that you expect from RGGB OSC , CMOS chips. https://rcfmitch.wixsite.com/altair-s...
