I'm sending questions about the mount to the list, in the assumption

that other people will be interested in the answers too.



I'm very happy to have been 'notified' that I can place an order for

this mount, but have questions re the optional 'precision encoder

system' and the setup for an 'astrographic pier'.



Here we go:

1. Can you tell us more about the precision encoder system? Is it

optical linear encoder 'tape' wrapped around the RA axle tube, or

mounted on a ring about the axle, is it a 'can' inside the axis (in

which case, does it interfere with cable pass-thru)? Feel free to

elaborate ;-) I'm very interested in this option, but would like to

know a bit more about it.

2. Is the precision encoder system an additional feature, with all

other PEC hardware and features still present and used, or does it

replace them?

3. Related question: does the driving software (I'll be driving the

mount almost exclusively from a computer, not the keypad) have to

select it, or is it always 'engaged'? Does external software even know

it is present, or does the encoder system only talk to servo-feedback

hardware within the mount itself?

4. Does the precision encoder system improve pointing, or just

tracking? (I know there are other variables affecting pointing too,

e.g. refraction and flex of the OTA.)

5. If there should ever be a problem with the precision encoder

system, does the mount fail gracefully back to a 3600GTO without that

option, or ... ?

6. I'm pleased the 3600 has been tested in conditions even colder than

a Canadian prairie winter ;-) Was there some version of the precision

encoder hardware in the mount in Antarctica?



Changing gears now:

7. What does an astrographic pier look like?! (I've searched the list

archive, and see this question was asked but cannot find a reply.) I'm

assuming what is meant is something like an inverted hockeystick, or a

slanted tube coming out of the ground, so that the upper portion of the

pier is not vertical but points at the pole, thereby allowing the OTA

clearance to rotate around it. How then does the mount attach to this,

since the max elevation angle for the polar axis of the mount is 70

degrees? Maybe my slanted tube should point 20 degrees away from the

pole at its upper end, or does one leave off the lower 'fork' portion

of the mount? That's nasty as my pier then has to handle all the

adjustments.



Thanks in advance, kind regards,



Gary Billings

At the moment, I don't have anything that requires that big a mount.



But then, I guess I could mount both my AP160 and AP Traveler on it and also

a beautifully machined chair so I could ride with them. :))

i have both a left and right pocket and that is my point: he takes from one and puts into the other and claims he gave me something....

I guess I should feel blessed if I get even 50% of what was in my left pocket back when it goes into my right pocket.... usually there's a bit of "loss" in that round trip through washington.

Well one of the good things about living in the USA is that you can

send the gov't more than you owe in taxes if you want and if that

doesn't make you happy you can elect people that will take it out of

your and your neighbor's pocket and you can feel good about both.

It definitely depends on what you get for your money. We (Canada) complain

about our tax burden and are sometimes mocked for it but when you subtract

out universal healthcare (flaws and all) we are a very competitive

environnment. Key is to hold your legislators' feet to the fire and insist

on value for your tax dollar.

You don't have a war to pay for. So in that way your legislators were luckier

Yes, it's a privilege to live in a nation so rich in freedom so valiantly protected.



It's just a shame we must be timid as to the abuses of our government. Scaled or fixed

taxes are essential to this protection and our on-going global marching.



I don't mind paying taxes; I just hate to see them so blatantly wasted. We've become a

nation of indulgence and entitlement.



Imagine if our great political system weren't so political; what deeds we could accomplish.



My two cents.



El Capitan is proving to be a very impressive mount indeed. Congrats Roland! Can't wait

to see one at the 2008 AIC (www.aicccd.com/) in San Jose? I'm not sure if this will

fit in the overhead.



I'll check with Delta.....

Ladislav,



As for silly, why has this site suddenly morphed into a political

discussion blog? AP's fine products no longer interesting?

#22799 Aug 30, 2008

Ladislav,



You will find many former G11 users on this site who have upgraded to AP mounts.

And I will guaranty that all of them are more than happy with their AP mounts.

For many years I imaged with film cameras and my G11. But, when I switched

to a CCD camera I fought for a long time trying to get it to guide with the precision

that a CCD camera requires for sharp pictures. I was always tweaking something.

There is not just an incremental improvement with an AP mount, there are orders

of magnitude improvement.



When you are ready to upgrade you will never be sorry by choosing an AP mount.



Richard

It surely looks that way. I just bought a new Jeep, bit more essential than

a mount. I understand that from time to time used AP mounts are available on

Astromart. I should start monitoring them.







There is a lot of 'tweaking' on G11, currently the rage is $500 replacement

for the RA worm assembly. Keeps one quite busy.







Thanks for confirmation of my 'strong suspicions'.







Best, LN

Richard,



As a former user of a Losmandy G11 (10+ yrs), I can attest to your comments below. In

one case (G11), the mount works against you and one must always look for workarounds

and patches. In the other case (AP), the mount works for you and makes each session

nothing but productive and a real joy.



I accomplished more in one week with my AP1200 than I did in a decade with my G11.



Anthony.

Everything OK now. I am waiting for e-mail confirming my Astromart

membership - their website recovered from a busy week overnight and my

credit card was accepted.







Do I have enough money for this wonderful stuff? Does not look that way

right now. But eating very little and drinking even less may get me going.



Thanks for additional info.

If I remember correctly, Herb York of Astromart-Anacortes, won't accept

anyone with an email address he feels is possibly problematic. I think this

usually

meant 'free' email accounts like 'Hotmail'.

Don't know if this is still the case.
