Hi Richard,

No it is not normal. Most likely the image scale is set incorrectly. Why don't
you email me your log files privately and I will take a look.

Thanks,

Subject: [ap-gto] Improvement to PE using Pempro with AP900 GTO

According to PemPro and based on 6 complete worm cycles, the PE of my
AP900 GTO without correction is 6.5 arc seconds peak to peak,
which is
obviously well within the specified 7 arc seconds and
testament to the
quality of the mount. Having loaded the PE data directly into the CP3
control box and measured the error again with PEC switched
on, the peak
to peak value has reduced to 5.2 arc seconds. Not being familiar with
what figure to expect, I would be grateful if someone could tell me
whether a reduction of 1.3 arc seconds in the peak to peak value is
normal? Thanks in advance, Richard

Thanks Konstantin and Anthony,
I may try this (PoleAlignMax) prior to using T-Point as that is my
ultimate goal. I was just curious about some of these "quick"
routines as my friend had told me that the keypad algorithms worked
so well.
Thanks, Rick

I have been doing just polar align with the Polar Scope and

good enough, that I aligned my setup using that technique and

I was told by a friend that is using a nearly identical setup,
that
the A)North Polar Calibrate and B)Two Star Calibration would
give me
bettter alignemnt than the Polar Scope, so I was curious.

I was thinking of going to the "Meridian Delay" routine or
CCDOps
routine to see if that was better than the Polar Scope.

Eventually I will go to a T-point type program with the
permanent
mount.

Thanks for your tip on the portable setup.

You can do any ol' thing that works. The keypad is full of
great
tools. If
the above sequence works fine for you, then there is nothing
further I can add.

Here's what I do when setting up the scope at a remote site:

1. I place the mount and scope in Park1 position using a
simple
carpenter
level.
2. I start the keypad in Autostart NO and press Resume from
Park1
3. I then slew to Park2 and level the tube manually using the
carpenter's
level.
4. I slew back to Park1 and level the tube using the altitude
adjustment.
This completes the initial setup of the altitude axis.
5. I slew to a known star (or the sun or bright planet) and
adjust
the
azimuth to bring it near the center of the finder crosshairs.
This completes the initial setup of the azimuth axis. Both of
these
adjustments can be done in the daytime, which allows me to
find
bright stars in the
telescope at low power for further polar refinement before
the sun
has set.

When these adjustments are finished, I refine the altitude
axis by
using a
star near the meridian line and using the meridian delay to
pick
it up on either
side of the mount. This gets the altitude axis quite close to
final position,
and takes less than 5 minutes. When that is done, I do a
drift
align using my
CCD camera. That can take anywhere from 15 - 25 minutes,
depending
how fussy
I want to be.

No. You may not have turned on the PEM. If you don't turn it on, it won't
play it back and you will not get a meaningful reduction of PE.

What model Pelican case to use for AP900

Joe Zeglinski
 

Hi,

Waiting for arrival my mount, I wondered what Pelican case would be
suggested for the AP900. Handle and wheels might be an asset, to consider.

I have seen a post suggesting it was a mistake to go for the #1660, since
even the empty case alone, weighs a lot, and lifting both halves of an AP
mount packed in one case, is likely to be a back breaker.

If anyone is already using a "two Pelican case" combination, "with
handles", is it possible to set the two cases on an edge, and flip the
handles, tied across each other, to form a bridged "observing seat" (or, as a
low accessories table) - just a thought? Would be nice to have a secondary use
of the empty cases, rather than having them just sitting there unused, in
preparation for the return from the session.

Thanks,
Joe

What foam compression factor is advised for AP900 case?

Joe Zeglinski
 

Hi,

I saw a post on the AP-ug group, where someone is using 90 lb/sq. inch
"closed cell ethafoam" as a lining for their AP mount. I have read that the
"foam dice" in typical cases, like the Pelican, get chewed up after a while,
and require a replacement - which costs a couple of hundred dollars US, or
more.

So, what foam compression PSI factor is recommended by Astro Physics, for
a travel case, based on the weight of the AP900 (complete, or in parts) - and
possibly for the AP1200, as well?

This has to do with how much deceleration can be tolerated by the mount,
in normal travelling, or worse, in the average toss or drop by the airport
gorilla baggage handlers?

Perhaps, as a guide, what is the PSI of the "hard" ethafoam that our newly
purchased AP900 or AP1200 come packaged in? I assume, AP has calculated the
tolerable damage risk of it's initial shipment to us, in their selection of
the hard foam, used in the cardboard boxes.

This information will be of great help in specifying the correct foam to
purchase for my new AP900 case, or more likely two cases. I assume this advice
would be based on the weight of just the RA and/or DEC assemblies (the manner
in which it is shipped to us), because one can't know if the counterweights
and shaft would travel separately, and if the hand controller were in either
one. The hand controller is already protected by the new rubber casing, so I
assume a one metre drop to a paved driveway, is survivable.

Certainly, a well considered recommendation, or a white paper by Roland, would
help.

Thanks,
Joe


Eagle Tripod - not for AP900?

Joe Zeglinski
 

Hi,

I was wondering if the new AP tripod would work with the AP900 - it isn't
in the advertised list of supported AP mounts? If, not what would the problem
be in using it with this mount?

I hate harping on this, perhaps way too much, but why didn't AP add three
vertically cut slots at the top of the Eagle pier post, down to the horizontal
ones? It would make it so much easier to simple drop the AP mount and adjust,
or lock into the adjusted azimuth.

Perhaps, as I see it, the one danger is that the user might use the
horizontal adjust on the pier, instead of the one on the mount itself, for his
location. Then, if he happens to align right at the vertical slot, or if he
forgets to twist the mount slightly await from the drop down slot, the mount
might pivot itself out of the pier. Of course, that could happen even without
the vertical slots, if he doesn't screw in or forgets to tighten, the 3 mount
knobs.

I think I would like to see the Eagle with drop in slots - guess it's a
matter of taking the new mount into a machine shop oneself, for correction of
the design.

one PEC run via the hand controller but you can't upload
any averaged PEC runs.

Hi Brian,

Can't you do the PEC averaging in software using a tool like
PemPro
and then replay the averaged data to the mount?

I'm a new AP900-CP2 owner and haven't got round to training
the
PEC
yet, but that was my plan.

I'd be interested to hear if my thoughts are correct from one
of
the
old-hands?

John

Re: Is there any talk of a CP4GTO controller any time soon?

Steve... <s-walters@...>
 

My AP1200GTOCP2 had about 5 arcsecs of periodic error. After training
it with PemPro, it's down to 0.1 arcsecs of PE. I did this close to 2
years ago and haven't touched it since.

Why don't you simply use PEMPRO for your PEC training. I had a

was even able to upgrade the CP1 hand controller software to
the latest 4.12 vesion...joe :)

I know you can't do direct-to-memory uploads on the CP2, but
what's to
stop you replaying an averaged PEC through the autoguider inputs?

I second what Paul and Roland say. Go take the CCDware tour, or go 'read' the information about PemPro. It is so simple, all
you do is follow the instructions then PemPro does all the work gathering the data for you. You analyse the data making
changes 'if you want' then another click and the data is uploaded to the mount and you're done. Refining the uploaded dats is
just as simple. Take some time to investigate this valuable package, PemPro..joe :)

I think Roland said it all, especially the need for that darn
computenator.!! ;-)

voiced by Richard Bennion, though Ray should have done the intro with
a pop-up to say hi.

Hi Paul, thanks for your response. Could you explain

how you get the PEC data from the mount

training is limited to what I did for my CGE so pretend you are
speaking with an absolute beginner :)
The PEM data is first gathered in the normal way by guiding (or autoguiding)
the mount with a CCD camera. The data is gathered by PEMPro. You then simply
smooth the data in the program routines and download it into the CP1,2 or 3
controllers via a serial cable attached between your computenator
and the CP1,2
or 3 controller. Once you have loaded it into the controller, you
can activate
it via PEMPro or via the keypad by selecting the PEM "Play" function.

With the CP2, you can use PemPro to avg out a bunch of multiple
revolutions of the worm, (and while its still turning) program the
averaged/tweaked result to the PEC. works fine, great result.
The CP3 uploads it instantly as a file, whereas the CP2 you go thru
the 6min+ worm cycle as it programs. For the very few times I do
this, I'm very happy with my CP2 controller.

A perfect thing to do on a full moon night.
cheers,
...paul.
p.s. you can also check to see what your non-PEC is at with your
recently acquired 900/CP2 using the trial version of PemPro. You'll
probably surprised how good the mount is without PEC on and may not
need it depending on what you're doing with the mount.
