Flocking the DOB

Well, I just got finished installing black felt inside the secondary of my 15" DOB. It looks great and was a real pain to put in too. :^)
I am hoping that I will get a little more contrast from installing it. I covered the entire inside of the secondary. It took about 3 hours to do it, maybe it will be worth the effort. I sure hope so, but at least it looks very cool!
I also discovered that you can do a nice job of aligning the focuser by inserting the laser in the focuser and turning the secondary over to face the ceiling. Then when your turn on the holographic laser the pattern is displayed on the ceiling! You can see exactly where the diag is in the pattern and then you can adjust the focuser to an extremely fine degree. The hologram can be adjusted by focusing until the tics on the pattern are just the same on all 4 sides. I got the thing adjusted perfectly this way. It has to be within .001 of an inch now. Nice easy way to do a quick check the collimation of the focuser as well. Quick and simple.

"I also discovered that you can do a nice job of aligning the focuser by inserting the laser in the focuser and turning the secondary over to face the ceiling. "

Would you explain what you mean by "turning the 2ndary over to face ceiling"?

I've got 2 of my small Dobs nice and tight with a Helix hologram laser collimator. But, I'm having fits trying to get the blasted 2ndary just right on a 6" f5. On the others, I just stuck the laser into the focuser and pointed the primary up to the ceiling and tweaked it. The secondaries on those were already centered. But, on the fast 6, the secondary is noticeably out of kilter with regards to both the focuser and the primary.

Everytime I loosen the screws and stick my fingers down there to adjust it, it seems like it gets a tad worse. It also seems like it moves as I tighten the lockdown screws. Any help appreciated. I'm actually wondering if I got a deal on this scope because the previous owner had trouble getting good collimation. It was so far out when I picked it up, that I'm not surprised the guy didn't like it. I've got it close, but it's not close enough for my eyes. I know it can be done, but it seems pretty touchy. I imagine it's just a matter of continuing to tweak it in increments, but if you've got a better way, I'm definitely in need of suggestions.

Also, if you've got any specific tips on flocking, I'd appreciate those as well. I'm definitely going to flock two of these. What do you do about all the screws that poke inside? I blacked them with a marker, but do you have to cut the f paper to fit around them, or just poke them thru?
Flocking the 4.5 doesn't look like it's going to be easy. I need somebody with kid-sized hands.

Thanks,

Floyd ; I take it your not a fan of offsetting the secondary. Your thoughts -----
