I'm loving this thread! I have a 150P-DS which is very similar to the 130. I've done a handful of images on an HEQ5 with PHD on a tripod, but I'm in the process of building my roll-off shed obsy with a AZ-EQ6 mount. I have a 500d that I will astro modify and I will see how far I can go with that from my suburban skies (probably about Bortle 5). Eventually, I will go to the dark side proper and get a CCD (hopefully a 8300 based set-up). But, for now, the game for me is to refine the process and understand how to push along that asymptotic curve to "perfection" i.e. that last 1%. Advice like the quoted above is priceless! I reckon I still have about 98% to go!
