To answer that, I did not have an external focuser with this system. When I
bougth this tube assembly last year Meade did not have any external Crayford
focuser attached. I used the internal (moving mirror) focuser. This method of
focusing is extremely difficult because of the severe image shift. In order to
do successful focusing manually, I had to approach the null focus position only
from one side so that the focus star would remain in the focus window (and
also to avoid losing the guide star). I would slowly creep up to the best focus
position and mark it with a piece of tape. Any time I overshot, I then had to
begin again on the original side of focus. It is impossible to do any kind of
remote automated focusing this way. If that is a requirement, you would need
to attach an aftermarket focuser that can accept larger than 2" accessories
such as our 2.7: telecompressor.

Yes, I was using the 27TVPH telecompressor. The Meade adapter that I used is
not on our web site yet (will be posted soon). It is model ADASCTLM27. This
threads directly onto the back of the Meade 3" thread. The telecompressor fits
into this adapter and then into that goes the ADA2003 (2.7"-2") adapter, which
allows you to attach any 2" accessory such as the STL cameras with their 2"
nose piece.

I have done extensive imaging (and soem visual) with a 10" Meade LX200R, with
attached telecompressor and STL11K camera - total weight about 36lb. The
mount worked flawlessly and very comfortably with that weight. It isn't the
weight, it is the moment arm. A very long refractor with the same weight would
probably be bouncy on that mounting, since it would need to be high up, plus it
would put more torque stress on the gear teeth.

Re: PEMPro with SBIG STV

Ray Gralak <rgr@...>
 

I agree.....
I've used an STV with two different AP1200GTO mounts and have
never used
PemPro, etc.
I now use the Remote Guide Head with an SBIG STL-11000 with a
1200GTO and
still don't use PemPro.
I've used both with the efinder to guide imaging focal
lengths up to 1200mm
with perfect results.
When doing film imaging I often did exposures up to an hour
long and now,
with CCD, routinely do 30 minute sub exposures with perfectly
round stars.
Hi Kent,

Of course you can get round stars without PEC even being enabled when
autoguiding. However, you may be losing a couple tenths in stellar FWHM (i.e.
your images would be a tad sharper).

-Ray Gralak


Re: PEMPro with SBIG STV

Ray Gralak <rgr@...>
 

Hi Edd,

It's not so much a matter of how smooth the mount is. Scintillation will cause
significant random (wrong) PEC corrections if you use an autoguider. Not only
that, the corrections are slightly delayed because it takes a non-zero amount of
time to get the autoguider's feedback to the mount. PEMPro can remove both of
these effects. Plus, with a newer 900/1200 mounts you can upload the curve
directly to the mount.

Hi Dick,

I'm not familiar with the output of the STV. It should work if you can download

Hi,

I am preparing a special adapter plate to go on the declination head
of my 900GTO (on the surface where you use to place a saddle plate.)

We use the metric system in Denmark and I have not been able to find
the bolts in the US system needed to fasten this adapter.

Would someone in US be so kind as to help me purchase some? I will
of course pay all costs involved. Or maybe you know where I can
order them online for international delivery?
(How about Astro-Physics? :-)

I'm talking about this type of bolts:

http://www.nf. <http://www.nf.suite.dk/bolt.jpg> suite.dk/bolt.jpg

In Denmark, we call them "Unbrako bolts". Are they "called socket
head bolts" in US?

The diameter of the thread should be 6.2 mm = 1/4"
and it should go in here (read arrow):

http://www.nf. <http://www.nf.suite.dk/declination_head.jpg>
suite.dk/declination_head.jpg

The length of the thread should be between 1.25" and 1.5"

Right now, I need 6 bolts, however, I gladly receive, say, 20 or
more.

The quality should be the highest of stainless steel (in Danish
terms "quality 12.9")

I very much appreciate it if someone can help.

After accepting the futility of self-help, I gave AP tech support a
call. 'Mechano-sleuths' Christine and Wally predicted binding of a
gear in the RA motor 'box'. This was diagnosed by comparing the
tension differance in RA to the Dec gear box.In my case great effort
was required to move the small gear that engages the plate sized gear
in the RA housing. Slight loosening of both SS cap head bolts that
attach the black RA gear box to the RA housing did the trick. Wally
explained that these problems develop, not from customer abuse to
mount (from travel,dropping, etc.), but just plain and simple "Majic".

Hi Bill,

or in direct English translation:
- "Been there, Seen it, Done that , got the T-Shirt"

That is yet another interesting tale of how bad UPS service can be, but at
least they are regularly (bad).

This business with a 3 box or a 5 box shipment of our AP mounts - as in
your case and mine - might work better if AP and UPS found some way to handle
the entire shipment as ONE UNIT. Maybe the only way is to strap everything to
a wooden pallet, but that would likely be more expensive. AP shipping dept.
should contact UPS and find some way of UPS keeping a multi box shipment
together.
Obviously, if they put a separate UPS tag on each separate box, to the UPS
driver, and the system, they are just totally different boxes, unrelated to
each other. I'm just surprised this kind of shipping hasn't run amuck more
often.

Oh well, if it takes "a few years" (in the past) to get an AP product from
your spot on the Notification List, then what's waiting a few more months for
UPS to deliver it.

Joe,

Been there, done that, have the t-shirt. Years ago when I took delivery
of a mount that was shipped in 3 boxes, box 3 arrived first. I paid all
the charges and was told by the driver, that the others were probably
just on another truck. That was beginning of my saga and my exerpiences
with UPS. It took 2 months for the other boxes to arrive. At several
points, UPS tried to claim that boxes 1 and 2 never even existed even
though they were logged in their system. They eventually found them
sitting in Detroit, waiting for box 3 to arrive, so that they could
clear all 3 through customs similaneously (at least that was their
explanation). When the other two boxes did finally arrive, it took
another week for them to admit that they had been paid, even after
producing the cancelled cheque.

On another occasion, when damage was done to something, they tried to
force me to pay all the taxes, duty and brokerage charges on the value
of the repairs. Again, another week (after waiting 3 months for repairs
to be done) of dealing with supervisors to make them realize that this
charge, should have been part of their initial assessment. There was no
way I was going to be out of pocket for their screw up.
