Sorry to bore you all but very accurate tracking also helps to get the signal to noise of even the dimmest of stars above the inherent background noise.
In the past these dim stars were so blurred by lack of accurate focus and inadequate tracking that they looked like noise. So I eliminated them by processing them as a black background.
If you did not notice I did take some images with the 100ED and the TAL200k just to see what was real and what was noise.
Oh and another thing the original JPG from the 73MB TIFF is a 15MB JPG.
