(Sorry for the cross post - Meant to send it here to begin with).



Happily, my name came up a little while ago for the 900GTO mount, and I am

finalizing my decision on the Pier and related accessories. I will be using

this mount primarily in my back yard on grass for CCD imaging, and in the

mountains at primitive dark sites.



My current list of accessories includes the ATS Pier, but I have never seen

one of these "up close." Is it well suited to primitive sites? Can it be

leveled easily? Does the AP Pier offer any advantages?



Also, I am unsure about how high I want to go. My thinking is either the 48"

or 54" would be the best choice in the long run (Despite my interest in

imaging, I will still be using it extensively for viewing with a wide range

of scopes). Is there any kind of general consensus on this? (BTW, I am

6'1").



Lastly, can anyone recommend a "Must Have" accessory for this mount?

(I understand the Keypad Protector is in this category... Any others?)



Here is what I am planning so far:

Counter Weight 10lb

Counter Weight 18lb

Polar Alignment Scope

Keypad Protector

Cream White 8" x 54" Pier

Adapter Plate

Trays for 8" Pier

Support Bars for Trays

2" Bubble Level



I appreciate any feedback.



Thanks,

Jay E. Potts

I'm 6' tall, and use an astro-chair w/my 48" piers (w/a Cassegrain

OTA on one and an AP 155 f/7 on the other). I would not want the

piers to be any taller. However, you might consider a taller pier if

you have a longer f.l. refractor.



AP's piers cost considerably less. The ATS has the advantage of not

having to schlep and assemble multiple parts.



Do you really need the polar alignment scope with the 900GTO?



The keypad protector is good and cheap insurance.

You don't need to purchase the keypad protector, the web site states

that it's included.



Keypad Protector (KEYPRO)

Optional accessory, purchase separately (now included with the

1200GTO and 900GTO)

Hmmm... Well I don't "neeeeed" it.



If it is pretty accurate, then it would be a bit quicker setup than having

to drift align every time. Or perhaps get me aligned close enough - So that

performing the drift align would be a bit quicker.



If it not very accurate, then I suppose I could eyeball it, and drift align

when needed.



How accurate is the polar alignment scope for the AP mounts?



Thanks,

Jay

When I drift align after using the polar scope, I

average approximately 1/4 turn on the alt-az knobs.

Sometimes I only have to adjust one direction. So i'd

say the polar scope is accurate, if correctly

adjusted.
