Mission Overview �Two tasks Capture photos for dark current Take CCD video ▪ Possible time lapse

Mission Overview �Dark Current How a camera works Part 1: ▪ Each pixel works like a bucket collecting light ▪ Makes a count based on energy ▪ The more light energy, the more counts ▪ A black picture should have no pixel count ▪ But this isn’t true, dark current adds energy -> ups pixel count ▪ Dark current is based on thermal energy ▪ As long as camera is heated, there is dark current

Mission Overview �Dark Current Continued A hot camera will produce a washed out picture:

Mission Overview �Dark Current Continued Can reduce dark current by cooling camera Measure dark current by taking black picture ▪ Measurement used to subtract dark current from telescope pictures

Mission Overview �Dark Current Continued If we can just subtract it, why waste power, weight, and energy to cool it down? ▪ Two parts to dark current ▪ Average—can be subtracted ▪ Random—cannot be subtracted �Can still have a washed out picture ▪ Can accidentally subtract out faint stars

Mission Overview �Video Capture How a camera works Part 2: ▪ The Bayer Filter

Mission Overview �Video Capture Continued Bayer Filter isolates red, green, and blue pixels Computer determines a true color from average Twice as many green due to eye sensitivity Make the computer work backwards
