Hi Rod,

Like the post - here are my thoughts

1. There is no cure and no group that will reduce your obsession, only a lot of fellow addicts to egg you on.
2. Telrads are wonderful. My beloved used to laugh at me mounting my dob to line it up. I like to use one in conjunction with right angle finder as Robert mentioned - sometimes a magnified field is useful and a telrad doesn't have this, but a telrad or rigel quickfind is the most useful pointing aid
3. I bought one of bintel's observing chairs - a fantastic device which is useful for a variety of purposes - I use mine when shaving our dogs, servicing my bike and a whole lot of other jobs. Mind you, with basic carpentry skills, it wouldn't be hard to make one.
4. I found that the fan modifications outlined by Scott Tannehill at http://www.iceinspace.com.au/63-400-0-0-1-0.html greatly reduced dew formation with my former GSO dob on both mirrors. Might be worth trying, but if your scope is a truss dob, a shroud might suffice. I found with scott's project that I only really needed to put a baffle in the tube to deflect air over the mirror and a gusset on the back of the tube to ensure the existing fan didn't just bounce the iar off the back of the primary. The fan didn't need any work. Total cost was about $25

I'm glad to hear that you're having so much fun!
