1. D 14 DARK image which be calibrated by BIAS Field D B gt 3 Capture FLAT Image FLAT image can be used to rectify the problem of the center light but the edge dark which caused by the vignette of optical system It also can be corrected the problem due to some small dust on the CCD sensor glass surface Flat field calibration method is this you need uniform luminous lightbox The lightbox will be placed in front of the telescope You would set the appropriate exposure time then continuous shoot 10 50 frame flat field images Save and overlay these images to form a FLAT Master image save the image To obtain an accurate flat field calibration Please note the following matters You have to take immediately flat field images before the shooting or after finishing shooting Like do this in order to avoid dismantling the device dust on CCD surface and vibration of CCD cause the change of location The scope of exposure 1s better for 30 of the maximum dynamic range which means you have gotten 20000 30000 pixel of flat field image Images of BIAS Master DARK Master and FLAT Master will be calibration data as image post processing of the captured images Guiding by using IMG1S for astronomic photography IMGIS contains a guiding spot it can be used as a guiding CCD with ASCOM IMGIS uses 1 1 bin and normal download speed default 1 Guiding by using IMGIS in MaxIm DL 1 Download the newest ASCOM software in http ascom sta2.

5. caused by dust on the surface of the CCD Image calibration is a critical step for serious astronomical photography In order to obtain accurate calibration information you need to use the IMGIS temperature controller CCD should be set in fixed temperature state And temperature should remain the same when shooting The Calibration Principle of CCD Image Calibrated image L B D B F B L D F B 13 There L is the actual shooting image D represents the Dark Frame images B represents BIAS image and F means the FLAT image l Capture BIAS Image BIAS image means exposure time of images is Zero You need avoiding any light to enter into CCD Sensor when you shoot image So you have to cover the lens cap of camera Set Exposure Time to 0 and then use the low speed to shoot many 10 50 sheets BIAS image Save and overlap them Use the function of average overlapping do not match with position to get one BIAS Master image Save this image Partial Cropped BIAS Image B 2 Capture DARK Image DARK Image means the image which of the exposure time is the same as the time it took officially You have to avoid any light enter into CCD sensor Therefore you have to cover the lens lid The exposure time should be set the same with shooting time and then use the low speed and mode 1 1 to shoot about 10 50 sheets BIAS image Save and overlay these images to form a Dark Master image Save the image Partial Cropped DARK Image
