Thanks for the advice, I guess deep down I know what you are saying makes perfect sense. Cooled will always be better for LE Astro, being in Perth summer nights are 20+ so no joy there and it rains in winter, nice. I think the advice is sound, rather wait and get a cooled camera later. I totally get the fact that you can setup a library of calibration frames at specific temps etc. Will make the whole process that much easier! And sensor size to boot.
