Hi George,



I bought the Stellarvue 155mm rings and have had no problem withslippage. There is about 5mm of space left after I tighten therings down so, plenty of leeway.. If your rings are AP and theyare fully closed (no space) when you think they are tight, you maywant to try these or add some felt. The holes on top and bottom ofthe SV rings are the same as the ones on the new version AP ringsfor the 130 GTX and about half the price.

.George,



.Recently, I've been having a problem keeping my 155mmf7 from sliding down in the rings when it's pointed atthe zenith. I tighten the knobs as much as possiblewithout over torquing and causing the pin to break(that happened to my friend). Do you ever hear aboutthis and do I need to replace the felt or use thickerfelt? Does AP offer a re-felt job? ;-)



Thanks for your input!
