Discovery 10" f4.5 PDHQ Weight

So I want a 10" for my first scope after 1 yr with binocs, and I've heard nothing but great things about Discovery optics (which is my priority along with weight). But with the weight of the 10" f/6 PDHQ, I'm just too worried it will not get enough use as my observing sessions are usually 1-2 hrs and spur of the moment (I'm spoiled by the ease of binoculars I guess).

Then I learned that Discovery often ships the 10" PDHQ in f/4.5 upon request, but the salesperson I spoke to could not give me a weight. Are there any owners of the f/4.5 that can tell me the weight of their scope? Also, any comments on the performance with respect to the faster ratio (is coma an issue, do you use a paracorr, etc.) would be greatly appreciated. Thanks for the help!

Hi Tim,

I have 10" F/4.5 PDHQ. Everything is exactly the same as the f/6 version except the tube is 49" long vs 64". I have not weighed it, but guess you would save maybe 10 lb in the sonotube difference. I've been considering boring some 2"-3" diameter holes in the altitude bearings to reduce weight, since those hunkers are 12"+ in diameter double thickness solid particleboard. Otherwise I am very pleased with the scope.
