Re: AP1100 park position question



I live in western Colorado and have had the PierTech adjustable pier (which, AFAIK, is a Linak) for 6 years without any issues...and I bought it used from someone who lived in Silverton (I live in the colorado banana belt by comparison).  Temperature range here is frequently -5C to +25 and has been, on occasion, -15 to +30 over the course of a year.  That said, I have never operated it close to those extremes (my limit, not the equipment!) 8-).  Storage range is -20 to +70C, which I would equate to just sitting in the observatory without movement.

Also it will go through its full 50cm range of motion in 25s (2 cm/s); so the 19 minute pause after one minute is never a factor.  I do not try to fine-tune.  I have the operational height marked on the inner column.

If I was going to change anything, I would pay the additional $1000US over the PT2 and buy the dual pier (PierTech PT3) to ensure stability.
