    Thanks for the insight! When you use that piece mentioned for Astrophotography I’m guessing you cannot visual observe at the same time? It replaces the eyepiece?

    EEA is live visual observing in that you look at a screen while the image of what you are looking at dynamically builds so brings further life to the smudge and may resolve shape and colour. But yes it is either eyepiece in the focuser or camera. I was only thinking about if you find your bortle sky hard work on DSO what else might extend your hobby

    Also, for noise reduction from heat on a long exposure, my camera will automatically take a second exposure of equal length as the sensor is cooling down to map out the heat distribution and use that mapping to reduce noise from heat for that specific capture.  I can not turn this function off.  So effectively if an exposure is 5 minutes, it will take 10 minutes to actually process.  (I am an extremely patient man by the way.)

    it might be an idea to test your camera now on a static tripod. Face east or west keeping altitude reasonably low take a single shot with your widest lens on a dark clear night.

    Taking your widest lenses 600/28 gives roughly 21 seconds before startrails.

    Take an image

    Turn off in camera noise suppression if you can

    Take another shot

    Compare images to see what impact in camera noise suppression has on the stars, you may find some have disappeared, this may be acceptable for you.
