Discovery 15" PDHQ Info

if you own one or have used a discovery 15" pdhq solid tube dob, please give me all the information that you can about the ups & downs of this particular scope. im about to buy one & would really like your input. id like to know about the action is it smooth? is the 2" focuser a good one?, are the optics outstanding or a dud? anything will help.
thanks david

The 15" PDHQ is an excellent scope, the 2" focuser is made by JMI and is really smooth, the optics are really good. The down sides are the weight of the tube (about 100 lbs), and the eyepieces supplied with the scope are not the best in the world. Also the mirror mount is not the strongest, I had to use silcone glue on the back and sides of my mirror in order to insure it wouldn't fall out of the mount when the telescope is near horizontal (I learned the hard way and I now have a minor scratch on my mirror)
