I received my 12.5" Discovery TD a week ago today. I've noticed a fair amount of mirror shift when moving from a horizontal position to, say, the zenith or...
Marc, ... stick it to the cell. I Have a 12.5 PDHQ I got in Dec. and seeing that~~~ {had to take the mirror out cause it had to come forward 1/2" to come to...
Marc I had the same experience with my 10"f6 and 17.5"f5 scopes. Both times I tightened the plastic set screw that pushes on the side of the mirror and it...
I'm remounting my 8" DHQ on an EQ mount w/ Parallax rotating tube rings. This rings need to be slid onto the tube from the end, so I have to remove at least...

Steve and Louis, thanks for the recommendations; I'll first try tightening the plastic set screw and then move on to the silicone solution if that doesn't...

Hello Don, Thanks for the post. So, if I have what you're saying straight. You're saying that in order to use my current DCS's with a tracking platform, I will...
Bill, When you say 'center the platform', do you mean having the platform at the mid-point of the total amount of travel? That's not the starting point that I...
Hello Don, Got it!! That makes alot more sense to me..... The reason I was saying mid-point is because that is typically where the leveling of the scope would...
