Ken, congrats on making an excellent choice. The HEQ5-Pro is clearly that extra step up from a CG5/LXD75 and is certainly worth the extra dollars. My LXD75 is fine for visual, and it might even do me good if I have stab at entry-level astrophotography, but I can feel it in my bones that I have outgrown the limitations of the mount quite quickly. So I am contemplating the Vixen Sphinx or HEQ myself (StarBook looks really sexy, ahhh another gadget...). It's funny how I've become a lot more critical only this year before I commit to buying any astro equipment ie. doing lots of research and opinion seeking from all of you guys ( I love it....!) Cheers, Fox.
