visonneau-vincent <visonneau-vin@...>
 

Hi
I would like to know what must i do to upgrade the gto keypad.I see a
function "load" but there is'nt any explanation in the manuel.There is
some mistake on the magnitude object (in the catalogue,much objet
where indicated mag 40.00?????).Where can i found the list of the
Abell objet include in the gto keypad,i read that the gto Abell
catalogue is not complete and i don't know which objet is in the list.

Computer Question: Paul Hyndman

Derek Wong <dawong@...>
 

Company Seven called yesterday to let me know my long awaited mount
(600E GTO) is now being made and will soon be delivered... Great!
(But)I really haven't given much thought as to what computer I was
going to use for the Digital Sky Voice software.

A friend pointed out a series Panasonic has called "Toughbook". These
seem pretty rugged (gel mounted HDs, secured harnesses, magnesium case
and frame, inner membranes for moisture protection, etc. etc... sort of
a mil-spec type construction). I don't know if that would be overkill,
but I am kind of paranoid about the dew, coldness, and "things that go
bump in the night" type nasties that could befall these units.

I'd appreciate any feedback as to what units are working well for you,
and which ones aren't. Also things that seem to be weak or strong
points to consider (ie: poor displays when cold, power hungry [I use a
17AH 12VDC battery currently with my G11], or any other facets I should
consider).

Lastly, I followed the thread for the cordless microphone interface and
gather the consensus of opinion was that the Radio Shack units were the
way to go. Is this correct? Any preferences as to which of their
models?

Thanks for your input!

Dome Automation

Kacenjar, Steve
 

Hello,

I am considering automating my observatory. I would first like to link my
GTO drive so that the doors of the observatory opens in the direction of the
scope. Has anyone done this that can give me suggestions? What I believe I
need to do is to simply retrieve the effective azimuth of the drive and feed
it into an appropriate hardware dome controller. I am thinking of simply a
timing command to rotate the dome by a computed angle. I would use a
electrical rely to turn on and off the dome moter.

I appreciate any help you can give me. Thanks.

A handmade 1200

N. Foldager
 

Hi,

A friend forwarded this add to me:

------------------------------------
ForSale: Astro-Physics 1200 mount, handmade!!
This is 1 of the 10 handmade 1200 mounts produced in England prior
to production. Beautifully crafted from solid billets and stock, no
sandcasting. Includes High resolution encoders, current 9000
handcontroller, #18 counterweight, large head with Losmandy type
adapter.

$6000 plus shipping
-------------------------------------

I wonder, what is that for a kind of AP 1200?
Handmade?
By Astro-Physics?
In England?

Would it be compatible with todays accessories?

Would it be recommendable (if in good condition)?

The price seems a high to me for a used mount.

Best regards,

Niels Foldager

Re: 110V to 12V Converter

Terry Johnson <tjohnson@...>
 

Tim, my converter puts out 30 amps at a straight line. I have drawn a picture of the electrical wiring diagram for my system to include the ST-4, Kendrick Dew System (4 band system) and the mount, plus the PC and so on. You will need VISIO to open the document
 
Let me know what you think.

In Short, you wont damage you equipment at 14V.

I use two 32 AH Gel Cell batteries to power my 1200
Mount, ST-4, Dew Heaters, Dew gun, and Computer. When
the batteries are fully charged they sit right at 13.9
volts. The first thing I turn on is the mount, which
is getting the surface charge of the batteries. But as
soon as I load the batteries with the components the
voltage drops, the same should happen when you us the
12V convertor. I think more importantly, does your
convertor put out enough amperage to power all your
accessories. The AP mounts use 2 amps when slewing and
the ST-4 uses 0.5 amps mostly for cooling (if I
remembered correctly). Another question is how clean
is the power delivered, a good power converter has an
output that is almost straight line on a oscilloscope,
while the others display bumps or jagged lines.

I hope this helps,

Tim

Re: 1200 tracking accuracy at 3100mm focal length

John J. Kasianowicz <surpher@...>
 

Nice images! The picture of M82 has a lot of detail.


I've tried a Nikon teleconverter with my 12.5" f/7 newt on the AP 1200 GTO
mount. It figures out to be 3100mm focal length at f/10 with the
teleconverter.
I did some 2 hour exposures of NGC 891 and M-82. Tracking was excellent.
The AP 1200 is certainly up to the difficult task of tracking at long
focal
lengths. See the pics at:

Re: autoguiding with mx916 and AP 900gto

Derek Wong <dawong@...>
 

I bought 3 weeks ago a Starlight Xpress mx916 ccd camera,the
manufacturer tell me than this sort of camera can do selfguide.I would
like to know if someone try autoguiding an AP gto mount with starlight
Xpress product,what kind of cable must i buy to do autoguiding,the UK
manufacturer can't say me the exact name and reference of this cable
because he isn't familiar with AP product,christine Schmidt (customer
service of AP) tell me the same thing because she isn't familiar with
starlight product.
Vincent:

I would ask the people at Adirondack (www.astrovid.com), because they
are familiar with Starlight Xpress and work in the U.S. and sell the
AstroPhysics DSV software.

I am interested in this also, since my wife just got a Starlight Xpress
MX-5C. I read on the Starlight Xpress site that:

3) If you wish to autoguide an LX200, all that you need
is an RS232 interface lead from the serial port on your
computer to the serial input of the 'scope. Most other mounts
only have an 'ST4' autoguider input, and in this case you
will need one of our 'serial interface' units between the
serial port and the 'scope.
I think that you would need the "Autoguider interface module" at
http://www.starlight-xpress.co.uk/products/
This should plug into the AP 900 GTO.

However, for self guiding they may be redesigning the module--this is
why you should talk to Adirondack first, because you may want to wait
until they make the new one.

Re: Motorized Focuser

Ray Gralak <ray@...>
 

Hi Terry,
 
I didn't know what your specific intentions were so I told you about my setup.
If you are using a notebook computer for both inside and outside imaging
then you don't have an issue. But my P-II 266 MHz notebook doesn't have
enough "Umph" or disk space to handle too many ST-8E images (1530x1020),
so I gave up on using it except when I go remote.
 
At home, my mount is not permanently setup so I have to do a polar alignment whenever
I move the mount. When doing CCD imaging I find that I achieve the greatest polar alignment
accuracy when I center my alignment stars on the CCD chip (manually polar aligning the scope
while doing this).
 
Having a PC stationed outdoors in my small observatory (i.e.shed!) allows me to do the
polar alignment and rough focussing there then connect the cables to another PC in my
house when I'm ready to control things from inside. And on nice evenings I can image
outdoors instead since my setup allows me that flexibility. It's the cold nights doing
CCD imaging that I'm trying to avoid with an indoor PC.
 
I suggested using Cat 5e ethernet cable because in one of your previous emails
you said you would be *200* feet away from your telescope. In another email you said
you want to view the images 'realtime', so I assumed your computer will also
be 200 feet away. This distance may be too long for a serial or parallel connection,
even with good cables. This is why you would need two PCs.
 
My suggestion was to use the ethernet connection to control the remote PC via
PC Anywhere, which would make your inside PC's screen look the outside PC's
and control it just as if you were at it. The remote PC would have short serial
and parallel connections to the mount and CCD cameras. Also 200 ft of ethernet
cable is a lot cheaper than 400 feet of Belden 8138. Although a good shed to put
the outdoor PC in will cost a lot more than the cable! :-) But you may not have a
choice at 200 ft distance (but you could always try it and see).
 
I hope this explains things!
 
Good luck,
 
-Ray

Ray, this is my second response. I do not understand why you refer to two PCs? If one PC can support two parallel ports (two CCD cameras) and two serial ports (TheSkyV5 and DSOV3), then you do not need two PCs. You control the environment with the two-way communications from inside the home.  <- In this example the PC will be located inside the home so you can view the monitor.
 
You also have the option of having the PC outside. With this environment, you have hands free guidance of the scope using the two-way communications network and visual viewing 'realtime' via the monitor. This approach allows you to keep your hands in your pockets or eat pizza while you shoot the breeze with your friends?

I believe the two-way communications environment that is needed can be done via a headphones/microphone combination with a belt-mounted transmitter that transmits to a reciever on the mic-in jack on the computer. The computer, in-turn, will communicate back to the sender with a computer mounted transmitter that is attached to the speakers-out jack on the computer. The sender will receive the transmission via the receiver in the headphones.

Very slow communications speed (when they connected) and the link would drop. This was using ZoomAir
wireless PCMCIA cards without direct line of sight. It was a lot better when the two PC's were real close
and in line of sight.
