bobs nobs/lx90 lnt

[josh (Luke)]

Hey all
Got my scope fixed, just thought id give a warning to those putting in bobs nobs in a six screw lx90. The instructions say to just make all coll screws slightly firm. Thats not enough, the lnt has very strong springs and if all coll screws are not very tight the mirror will pop away when you take out the first one and it is not easy to bring it back !
Just thought id let folks know
See ya

Yep I know what you mean Josh, I installed shorty collimation knobs from scopestuff which were noticeably shorter than the existing screws and had a bit of a battle. I don't know whether there are different (Bobs Knobs) models but the latest meade OTA's come with longer collimation screws and a different secondary holder than those of a couple of years ago. The shorty collimation knobs that I got from Scopestuff now come in 2 different models to suit both secondary designs.
