Adjusting ST-80 lens cell

I can't remember where, but there was a thread somewhere on this topic, I think. I picked up a little ST-80 for grab'n'go. The optics are very satisfactory, except for planets. I recall reading that these are often shipped from China with the objective tightened down for travel, and that loosening the cell improves the performance. I'm afraid that if I loosen the cell the objective will fall out. Maybe silly, but I don't want to wreck the scope. Does anyone here remember the thread, or have advice concerning adjusting the objective cell? Thanks in advance for any help you can offer!

Hi Larry
To loosen up the lens cell, pull the lens shade from the scope and with the scope pointed up, grab the retaning ring and unscrew it about a half a turn so that the lens is loose in the cell. Just barely retighten the retaining ring untill it just touches the lens. Tap the tube against the side of your hand and recheck the retaining ring. Don't worry about the lens falling out. you would have to unscrew the retaining ring compleatly to get the lens out. There is an execellant group on Yahoo called 80F5. I sugest you join and check out the file section. Download the tune-up file and read it. as it contains a lot of useful information for this scope. I have one of these and think they are great!
