Re: Advice please: Standard verus Rotating Pier Adapter

Joe Zeglinski
 

Hi Tom,

Yes, I forgot about that error.

I was probably thinking about the TOTAL weight of the mount, if I were to
lift it fully RA + DEC assembled (minus weights and bar). That is almost the
same as my G11 mount (minus it's weights and bar).

Though that seems strange - the G11 looks so puny compared to the AP900 -
the AP900 is more massive looking, more load bearing surface, yet a lot of the
excess aluminum has been milled away.

The choice is between doing "one heavy lift" (as for the G11) from house
to yard pier, or make two trips and save your back. That, along with the
better load surface, and of course, extra 10 lbs of scope load capacity,
swayed me to upgrade. Naturally, there were many other AP performance and
quality reasons.

Not sure where you are getting 35 lbs from. The RA aixs which includes
what you call the "fork" is listed as 26.5 lbs. The 900 mount is very
easy to carry and setup.

Hi Kent,

Yes, I dislike using the term "fork", for this AP mount's part, but that
is what they call the "pair of vertical plates and bottom plate" that support
the Polar axle. I guess it really looks like and serves as a "fork for the
assembly", but not a "fork mount for a telescope". That really confuses
discussions about mounts, since we use the short form "fork" to imply "mount".

What do you think would be a better term to describe the base plate with
the two vertical side plates? Perhaps AP might accept using a different term
to describe their "base fork", from now on.

Alternatively, we could simply change the part's terminology to a "yoke" -
or will that now imply a form of "horse shoe" telescope mount?

How about replacing the AP "base fork" terminology with the word "BENDIX"
(if that is the correct spelling)?
If I recall correctly, there is a "fork-like" sliding part on the shaft of
every automobile's starter motor, that momentarily pushes the small starter
pinion into the main gear of the car's transmission, when you crank the
engine - so maybe we can suggest that AP change their confusing term, to an AP
mount's "Bendix".
Any auto mechanics out there that can correct me on this?

Other suggestions?

Joe

'with fork' ??? What fork?

German equatorial mounts don't have forks, unless you are referring to the

Re: Advice please: Standard verus Rotating Pier Adapter

Hi Kent,

The way I figured it - the G11 head, complete, is 39 lbs, and no fun
lifting into position.
The AP900 RA with fork is 35 lbs. Add the RPA (about 5 lbs), and we are back
into the G11 weight category, which I was eagerly trying to get away from. It
still is an even possibility, but hauling the RPA around attached to the RA
assembly, is a minus.

Joe



Joe:
Roland even suggests that one can leave the mount attached to the RPA and
remove them both as a unit. If the pier is permanent, you can just replace
'the
unit' into the pier and probably keep polar alignment.

Re: Keypad problem ?

Joe Zeglinski
 

Thanks Dominik,

Are there two PCB's inside - one is the keypad, and the other, the
processor and display? I think Marj may be wondering if you had a problem just
with the keypad PCB ( which is made by another supplier), or the processor
PCB, if there is more than one board inside.

The picture will put everyone's mind at rest - or maybe something to watch out
for, in future. Anyway, it will help all of us, with a potential problem
someday.

clear on your post), perhaps we have a very slight misunderstanding
in

I have never seen "silver" used in PCB contacts or traces on
circuit

the "silver" comes in to play. Unless, silver is being used somehow

Also, circuit traces, even if they are the "old solder
standard", are
almost always covered by a green layer of protective "conformal
coating", on
good quality circuit board products, which must be standard for
Astro Physics
products, surely.

So, I don't quite understand where your friend found
anything "silver". Is

that are "silver coloured", in referring to the "colour" of solder
(traces)?
Even so, I am surprised he could get to the solder trace without

Be that as it may, it would appear that there was a possible
bad spot in
the "wave soldering" of the board, leaving a short segment of the
original
"copper trace" on the etched PCB exposed, which obviously has
corroded over
the last 5 years, or more. This break in the trace caused a loss of
some
signal in the Keypad circuit, which your friend expertly cleaned
and
resoldered - he has a good eye to have spotted it. Now everything
is operating
normally.
If so, I wonder about the quality checks made by the original

Have I got this right?

Re: Advice please: Standard verus Rotating Pier Adapter

Joe Zeglinski
 

Thanks Jeff,

That reinforces my decision to stay with RPA's on both tripod and fixed pier.

Actually, I had also considered having a machinist (horizontally &
vertically) "notch out" the pier mounting holes in two of my Flat Surface
Adapter (FSA), - one on the post, the other on the tripod - and leave a
"single RPA" attached to the fork, along with partially screwed in, (6) thumb
screws, so I could easily drop and twist the fork/RPA into either "slotted
FSA", just like a Losmandy G11 does into it's pier adapter. Then I figured it
is "almost" as easy as fiddling with those four screw in knobs on the fork (if
I don't lose one on the ground/snow). Besides, the RPA is pretty heavy, and
that would just about be a deal breaker for carrying weight, which was one of
the major factors, when I decided to upgrade from my two week old G11.

Appreciate this,

Joe

I've used both the SPA and RPA.

SPA on a 900 and RPA on a 1200.

I had my concerns/lack-of-belief with the RPA, but now I see the RPA is a
big jump over the SPA.
It is such a "subtle" difference that is THE BIG difference.

I suspect the RPA _requires_ the heavy duty az adjuster. But I suspect it
will work with the old style az adjuster, but not practically.
So, this would be the "only" reason to go with the SPA... but then the az
adjuster can be upgraded.

The only minor problem w/ the SPA is simply that if you ever need to move
the mount in AZ, you need to loosen all those bolts and retighten them.
The RPA is "no fuss". And it is SOLID due to the beefy AZ adjuster.

With the RPA, the AZ adjuster keeps it "set" in AZ.

With the SPA, the mount bolts keep it "set" in AZ, and the AZ adjusters just
"help keep it set".

Even with a fixed pier, I suspect there may be a need from time-to-time to
touch up the alignment.
(I'm not a fixed pier person, but where I live a) the ground moves every few
years (san francisco - living near a fault), and b) the ground is like clay
and moves with the change of seasons.)

Hi,

I would appreciate some advice about using the SPA versus RPA. I recently
purchased the RPA with my new AP900, since it looked like a better, wiser,
choice. Now I am considering a second pier adapter, for an alternative
permanent fixed pier.

I see how my RPA works , but I wonder, what are the difficulties with
using the Standard pier adapter, which made the RPA a more desirable,
somewhat
more expensive, option? I intend on transferring the AP900 between a field
tripod, and the permanent post in the yard, so the small inconvenience of
simply "loosening" the four hold down knobs for the Standard adapter fine
adjustment, may not justify the price difference, for me. There must be some

other aspect, or convenience, of using the RPA, I may have missed.

Much appreciated,

So where the problem was ? According to my neighbour the plastic
keypad which is inside is very sensitive to corrosion (he
manyfactures electronics for agiculture machines and uses this kind
of products). The paths are made from silver. Accourding to him it is
a rather common problem esspecialy that I bought my mount second hand

It may be the case that after some time you may have the same problem
as mine. My keypad has been successfuly repaired with no cost from my
side. As you said - Home repair is better than recycling. I wanted to
take some pictures of my neighbour work but he said that this was our
know how and we should keep it secret. :-)))

Anyway I remember the case with my FLI filter wheel USB interface.
Unfortunately I used 12V power supply form SBIG STV (different
polarization) and the chip responsible for controlling the stepper
motor exploded - quite a loud noise (one simple diode used in the
design would sort out the issue I think). The response for FLI
customer support was that it could not be repaired and I can get a
new one for US$199. Fortunately thanks to "home repair" (exchange of
a standard chip) it could come back to life and the cost for me was
US$2 (two dollars). :-)))

Trzymaj sie Jozefie.

Best regards,
Dominik

Czesc Dominik,
Jak sie masz?

Just as a side note on most "elastomer keypads" (like those on
your TV
remote) in general.
I don't know if this is the same type as inside the AP keypad,
though.

I have found that the rubber membrane on a "typical electronics
product
keypad" leaches out some kind of oil as the years go by, probably
more if the
push buttons are used very often, like "TV channel surfing". I
suspect this is
the embedded "rubber mould, release agent", that remains behind in
the rubber
during manufacture, and slowly comes to the surface. Surprisingly,
the oil
film on the PCB, seemed about 1/16 inch thick! Quite a puddle, not
just a
film. There is no way that the carbon bump under the rubber button
could make
electrical contact with the etched copper pattern under it, through
that much
oil. I have now repaired my old Jerrold TV remote keypad about 3
times, and a
few others for relatives, simply by taking the case apart, and
washing both
the rubber sheet and the matching contacts on the circuit board. I
just poured
the Palmolive soap on the PCB, dunked the circuit board in the
sink, and
gently scrubbed off the oil in the mild sudsy dish washing soap
(NOT dish
washer detergent). On one unit, I tried, (unsuccessfully), just
spraying the
PCB with Windex, Isopropyl alcohol, or similar degreaser, but this
scum
requires a bit of rubbing with a good soap to make the contacts
work longer.
The keypad worked fine for another couple of years, or more, before
my
favourite button (channel skip) leaked out more oil, and another
washing.

By the way, the oil wasn't from kitchen cooking grease in the
air, since
the TV remote pad was always in the living room, and certainly hand
oils can't
leak through a full, solid rubber, sheet of buttons - so there
seems to be no
external source of this thick oil cover, other than the rubber
membrane
material itself.

Mind you, such home remedies may be frowned upon by the
manufacturer -
especially dunking the PCB in water - but since I was going to
toss it away,
I took a chance and continue using my original controller for many
years. The
water didn't affect the electronics after drying (isopropyl spray
like
eyeglass cleaner, might be a good final cleanup of any possibly
remaining
soap).
Home repair is better than recycling.

By the way - the AP Hand Pad has a 3 year warranty, so don't
try the above
home remedy, until it has expired, and you aren't sending it in for
professional repair.

I'm curious, Dominik, when you took the AP keypad apart, how
clean was the
PCB surface, and how old is your unit? I can't imagine why there
was a "trace"
needing repair, or how it might have been damaged. That is a
quality concern.
I wonder if the PCB can't take a lot of push button flexing, in the
cold.

Thanks,
Joe

Hi,

Just to let you know my problem has been resolved with some help
of
my neighbour who deals with electronics.

The problem was the plastic dial keypad which is inside AP keypad.
After reparing one of its paths now the whole keypad work just
fine
(at least it should for some time).

All the best from Poland,

Thanks for your response. The only problem is my location -
Poland,
Europe so it is not so easy for me to send the keypad to the US.
It
works and only the first row of left side keys do not work (I
press
it but there is no reaction) and as I use the mount in my
observatory
I can live without this first row. I have looked into the keypad
to
see how it works and it is rather simply built but I have no idea
what inside the keypad is not working properly.

Anyway thanks for your advice,

Hi to the Group !

I have a problem with my 1200GTO keypad. After unusing the
mount
for
one week I switched it on and from this time the three left
keys
do
not
work (1, 6 and Goto). All other keys are ok and the mount is
fully
operational with using RS232 conection but without having
access
to "1"
key I can not use goto without my laptop. Strange ? Has anyone
had
the
same problem ?

Best regards,
Dominik

Thanks Jeff,

That reinforces my decision to stay with RPA's on both tripod and fixed
pier.

    Actually, I had also considered having a machinist (horizontally &
vertically) "notch out" the pier mounting holes in two of my Flat Surface
Adapter (FSA), - one on the post, the other on the tripod - and leave a
"single RPA" attached to the fork, along with partially screwed in,  (6)
thumb
screws, so I could easily drop and twist the fork/RPA into either "slotted
FSA", just like a Losmandy G11 does into it's pier adapter. Then I figured
it
is "almost" as easy as fiddling with those four screw in knobs on the fork
(if
I don't lose one on the ground/snow). Besides, the RPA is pretty heavy, and
that would just about be a deal breaker for carrying weight, which was one
of
the major factors, when I decided to upgrade from my two week old G11.

Appreciate this,

Joe
Joe:
Roland even suggests that one can leave the mount attached to the RPA and
remove them both as a unit. If the pier is permanent, you can just replace 'the
unit' into the pier and probably keep polar alignment.

Hello friends. I'm getting my AP900 with 12" LX200R tuned up

That is very high and indicates that you need to put the Dec worm
into mesh.
You should also check to make sure that the final spurgear is tight
on the
worm shaft and is not rotating slightly when it reverses. If it id
not tight,
then tighten the setscrew that holds it onto the worm shaft.

Re: Advice please: Standard verus Rotating Pier Adapter

Joe Zeglinski
 

Good point, Kent.

I had forgotten about the side screws - AP warns against our even touching
them.

I was considering drilling a hole for a locking set screw - about half
inch inward from the gap of one or both azimuth "adjuster knob housing", on
the RPA. That way, I couldn't simply move the selected fixed one, ruining the
careful setting without thinking, as I replace the mount base and retighten
the opposing adjuster.

Thanks Kent - that was just the answer I was looking for.

Now I'm glad I got the RPA, and will likely go for another. Although I

now.
So if there is any minute ground shift over the short year or two, the RPA
should give me less hassle in minor very precise, alignment touch ups.

Joe
Joe:
One possible problem with the RPA.
There is no 'real lock' in azimuth.
If you adjust azimuth in one direction using one knob and acheive the
position you want, should you move that knob again, the adjustment will be
lost. I
suggest that once the position you want is reached, to carefully tighten the
opposing knob up to the adjuster post.

Another possibility is to completely tighten the resistance adjusting scews
(2) on the outside edge of the RPA. These are usually used to adjust the
tension of the rotation of the top plate, but I'm guessing one could tighten
them
all the way, preventing the top plate (and mount) from moving.

Joe:
I believe the Revolving Pier Adapter was produced primarily for those who
don't have a permanent pier and set up and tear down, either in their own
yards
or some remote site. While the original standard pier adapter works great,
when
doing polar alignment, loosening and tightening the 4 screws can slightly
shift the alignment. With the RPA, this doesn't happen, making polar alignment
less time consuming.

Re: Re-run Made in America segment with Astro-Physics

Hi Rick,

Whose site was the FTP download link? The stations or this group's, an in
what section (Files, Photo)?
Anyway, I did a general search on "Ratzenberger", and saw all the messages of
many others wanting to see the program, but having no access to the US TV
channel. Interesting "legality" discussions, as well. I wonder, if a copy were
on the AP install CD, if that could be considered "private viewing" to pass
legal muster.

I guess I am out of luck of seeing it, otherwise. Oh well, maybe the flic
wasn't that big a deal, after all.
