ive recently attempted a startrails pic and when ive come to process all the images in lightroom and then startrails.exe ive noticed that i have suffered from hot pixels, i had 120 frames all shot at 30" expesure at f5.6 iso 200 on a cold night so i thought i had no worrys about my sensor over heating.....now im assuming they were hot pixels, they were tiny white dots all appearing in the same place in every shot and are only noticable in the night sky/startrail pictures.....now my question is....does this mean the end of my sensor?? or could it just need a good clean??
i would post a picture up for you all to see but i was that annoyed i deleted them all in disgussed as i had spent nearly 2 hours on acold windy cliff top freezing my nads off for no end result except for a potentially dodgy sensor......
now ive just taken a shot indoors with the setting of 1/2000, f32 & iso 100 and uploaded it to my pc and there are no white spots, could this mean that my sensor wasnt warmed up enough for the startrails pictures??
thanks in advance for your advice
