Re: Focuser Question & Ext. Computer telescope control

Frank,

I have two optecs arriving next week. I ordered 3 adaptors to connect up a star diagonal, the Tak scope and the camera train. With the secondary focus capability, we should be able to go visual, align the scope and take a picture.

I did not order any cables from optec (expensive >$200) for the ME. We can make them for a few $.

I will check with optec next week for delivery. I may use your address.

Subject: [ap-gto] Focuser Question & Ext. Computer telescope control

Hi, I spent a fustrating evening trying to get my Meade microfocuser to
work with my Ext. computer. I am using Maximdl and chose the Meade
focuser, it would not open. I find that puzzling because I am able to
use the microfocuser with the keypad with it inserted into the focus
terminal on the mount. I was finally able to control the telescope, w/
a usb/ serial port cable. However when I chose to goto Spica the star
was nowhere close to being centered in the eyepiece. My time was
correct in the ascom dialog box and the keypad. I was connected to ext.
on the key and I shut down the power after doing so. When I decided to
disconnect and try the keypad to goto Spica, the telescope did not
slew. so I manual slewed to Spica I only had to move west and brought
it in the center and recal. I then tried the Ext on the computer and
the same thing happened. Seems like it is an hour off,but the times are
correct. I have summer entered in the set-up. Does anyone have a clue
what my problem might be. Thanks in advance for any suggestions! I have
a AP1200 GOTO. CP3 - Mike

Re: PEMPro AP: some more help needed!

Ray Gralak <rgr@...>
 

Hi Luca,

There are many other sources for drift besides periodic error. You should do
a careful polar alignment then make sure all knobs to fasten your telescope
to the mount are firmly tightened and that there are no cables dragging.
Even then you may see drift if your telescope has a lot of flexure, a less
than solid focuser, or your optics can move under their weight (e.g. an
SCT).

Subject: [ap-gto] PEMPro AP: some more help needed!

Hello guys,

I need some more help with PEMPro. Eventually the clouds
cleared and I was
able to collect 10 worm cycles of data on my 1200! After that
I created the
PE curve and then loded it into the mount following the
instructions. I then
saved the file with the curve I loaded into the mount, turned
the PEC on and
exited the program.
I thought that, after doing so, all I had to do was to go to
the keypad and
turn the PEM on (by pressing option 2, PLAY, in the PEM
sub-menu within
TOOLS). Well I did that and the mount's performance showed no
improvement: I
took 2 two-minute exposures, one with and one without PEM,
and stars had the
same amount of trailing. Needless to say the same thing
happened with 2
five-minute exposures.
When I decided to give up I also noted a strange thing: the LED on the
control box had turned yellow (nightmare!) and when I tried
to park the
mount I received the message that the servo was stalled (or something
similar). I had never experienced that problem before, so I was rather
alarmed. However that ended OK since after that I pressed
again the menu
button and the mount went into park position no.3 (the one I
had chosen). I
turned it off and then back on a minute later and the LED was
bright red
again (phew!) and the mount was working fine. I though that
was the reason
why PEMPro hod not worked alright, but I had the same result
after repeating
the above tests.

I also tried to keep the scope connected and PEMPro on with the PEC ON
option turned on while I was recording a 2 minute image, but again the
result was the same star trailing.

So I know there must be something I'm missing! What kind of
improvement in
the unguided tracking should I expect? Can anybody help me once more?

Hi,
I have seen these combinations as well as many others. I prefer
the
ATS or AP portable piers with the AP900. I prefer the wooden or
Eagle or similar with the Mach1/600/400 mounts.
The ATS is very simple, fast and rock solid. It works best with
nearly flat terrain. You will need a tripod based design like the
Eagle, wooden model, or Monolith styles to deal with steep
terrain.

Hi Dirk,

in any case the 900 is an excellent choice.

I have created and posted for you in the "Files" section, a
folder
named
"LT2APM" showing my setup: a 900 GTO on a G11 pier. I owned the
pier before the
900GTO, so I decided to keep it. I first used a local machined
piece to attach
the 900SPA on the G11 tripod, but immediately replaced it with
the LT2APM
adapter when it became available. It is much more rigid and
perfectly machined
so it matches nicely the top of the G11 pier with no noticeable
play or tilt
which is essential in imaging. This setup is also quite helpful
for me since
I carry the complete tripod /mount assembly in a single piece
in
my garden
each time I have to setup my equipment. My door is not large
enough for the AP
pier ;-)

I have used the G11 pier and 900mount in various
configurations,
with our
without guidescope, sometimes with a small amount of wind...it
works well
even with the 155EDF, so it should be fine with your C11.

But if you want ultimate rigidity, stability and maybe heavier
loads,
consider the AP portable or ATS piers, which have larger foot
radius and pier
diameters.

Good to see you here and glad to learn that you also picked up an AP1200GTO. We now

As for the choice of adapters, I would suggest you spend the extra few $ and get the RPA for maximum flexibility and irrespective if you are doing work at home or off-site to some dark side.

The euro today hit and passed $1.60 US ... as a result, there is no financial reason to prefer the SPA and for a few euro more you have the maximum possible flexibility.

Standard Pier Adapter (1200SPA) and acquire them both?

Re: G11 tripod for 900GTO

Wiggins, Rick
 

Hi,
I have seen these combinations as well as many others. I prefer the
ATS or AP portable piers with the AP900. I prefer the wooden or
Eagle or similar with the Mach1/600/400 mounts.
The ATS is very simple, fast and rock solid. It works best with
nearly flat terrain. You will need a tripod based design like the
Eagle, wooden model, or Monolith styles to deal with steep terrain.
Here is a link that shows the 900 (in the background) and 1200 with
ATS piers:

Hi Dirk,

in any case the 900 is an excellent choice.

I have created and posted for you in the "Files" section, a folder
named
"LT2APM" showing my setup: a 900 GTO on a G11 pier. I owned the
pier before the
900GTO, so I decided to keep it. I first used a local machined
piece to attach
the 900SPA on the G11 tripod, but immediately replaced it with
the LT2APM
adapter when it became available. It is much more rigid and
perfectly machined
so it matches nicely the top of the G11 pier with no noticeable
play or tilt
which is essential in imaging. This setup is also quite helpful
for me since
I carry the complete tripod /mount assembly in a single piece in
my garden
each time I have to setup my equipment. My door is not large
enough for the AP
pier ;-)

I have used the G11 pier and 900mount in various configurations,
with our
without guidescope, sometimes with a small amount of wind...it
works well
even with the 155EDF, so it should be fine with your C11.

But if you want ultimate rigidity, stability and maybe heavier
loads,
consider the AP portable or ATS piers, which have larger foot
radius and pier
diameters.

Hi,

I agree with Gilles comments. If you want to see what an AP900 looks like on a Losmandy G11 using the LT2APM
adapter (and I also use the RPA with it), have a look at the AP group's PHOTOS section. I posted a couple of my pictures in the second album in, "AP900/1200 COMPARED" - it shows my AP900 on a G11 tripod beside my former Gemini/G11 mount on its own tripod. The OTA is a 26 lb Questar-7.

Of course, the "AP900/Losmandy tripod" setup was such perfection, I sold the original G11 configuration, just a few months after I buying the latter :-)

I would, however, recommend buying the optional "Losmandy vibration pads" for the tripod - not because they glow in the dark for several minutes after sunset, but because they provide a large diameter support surface for the "spear-like" tripod feet on soft grass. If you leave the pads on something like cement blocks below the surface of the lawn, you will have a fairly permanent alignment and the Losmandy feet just slip into it's "slippers" for a quick set up every time. That is my own plan.

Joe

If you image......Do Not use any anti-vibration pads.
They can and will flex and move during the long exposure times of imaging.

At remote dark sites I use hard fired brick pavers that I had left over from
my patio.
They spread out the weight on each leg and keeps the leg from slowing sinking
into the ground, which would change the polar alignment.

RPA or SPA / or both?

Sabahattin Bilsel
 

Hello,

Greetings from Istanbul, Turkey. My name is Sabahattin, but my friends use the first 3 letters only :). Although I'm a lurker here and the other group since a while, this is my first post and I wish to say a late HELLOOO to all ...

I bought an AP1200GTO already 7 months ago. Some of the fellow owners have waited quite a long time for it. I didn't. It was there as I checked the website in September 2007. :)

But I'm still waiting... I thought I can import the the mount cheaper if I let it shipped to my cousin in California who should later send my toy with some of his freight by sea-cargo. But they had some problems, home change, deaths in the family etc... So, the mount is still in CA and should be ready to ship sometime in May. I hope !!! This will be the first AP1200GTO on the eastern side of the Aegean Sea :).

My plan is to use the mount in my observatory and may be travel to darker locations one ore two times a year. Therefore I planning to buy the Rotating Pier Adapter with Azimuth Bearing (1200RPA) for an easier setup in the field. Or shall I go also for the Standard Pier Adapter (1200SPA) and acquire them both?


Clear Skies,
Sab.

In the context of the complete response, it cannot. I cannot hook up

No, why should you. That would be a dumb way to attach things. I
would expect
that any program that can control the Robofocus be directly attached
from the

It is
