Adjusting understanding of TargetTemp in SC (it seems to be degrees C) - With gain of 0, brightness of 0, target temp at -10C - Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms - Checked CCD-TEMP field of final frame between each set, only proceeded when reported at between -10C and -7C - Lul SharpCap reports real-time temperature and target at bottom of GUI - With gain of 0, brightness of 0, target temp at 0C - Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms - With gain of 1, brightness of 0, target temp at -10C - Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms - With gain of 1, brightness of 0, target temp at 0C - Opened box a bit bc cooler was struggling to keep temperature - Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms - With gain of 5, brightness of 0, target temp at 0C - Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms - With gain of 10, brightness of 0, target temp at 0C - Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms - With gain of 50, brightness of 0, target temp at 0C - Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms - With gain of 100, brightness of 0, target temp at 0C - Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms - With gain of 150, brightness of 0, target temp at 0C - Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms - This took SO LONG. I need to figure out to use the sequencer in sharpCap. I saw that I could likely use the Deep Sky planner, but it only let tenths of a second stand for exposure times. This makes sense for DSO sequencing. There may be a way to get around it. ALSO I may not need this ridiculously short exposure time to suss-out the GAIN and BIAS levels. - Ran the sequencer for the ASI 432 with gain levels 0 and 25, but only the following exposure times - 0.1,0.5,1,2,3,4,5,7.5,10,15,20 - Saved this as calibrationTestSequence in SharpCap Folder in Z Drive. - Synced Data to normal gDrive folder - LEFT ASI2600 AND ASI432 in control room - These will obv need to be reattached. =====ToDo===== =====Notes===== =====Weather===== N/A =====Data===== {{tag>[mag]}}
