Re: keypad blinking

Hi Charles;
Thanks for the come back. Blink means that the backlight to the numbers on
the pad and the north south east west button goes out. The back light goes
out but....the main display stays on!!!!!After a few minutes the backlight
comes back on. Now i use direct current...it is not a battery problem...it
is not a power problem...it may be a loose connection or contact somewhere
????/

Wait,
are you saying your keypad completly shutdown. Ie: goes back to the
opening menu, where the version number is displayed?? or do you see it
blink, and then you are back to the point where you left off??

if it goes all the back to the begging then this is a power issue, or
something in my code is blinking the unit into a reset. I do not see how
...but it is something we have to look at.

please report everyone what version numbers of the code you are running
on
the hand controller??

Hi Ray,

Appreciate your input, however, I use a direct current source...the
keypad(or my keypad) blinks off and then comes back on again without my
turning off or rebooting......there is something more to this and I feel
it
has to do with the pad itself. Maybe a overheating devise that turns off
and
on to keep the keypad at a reasonable heat level??????How does that
sound????

Hi Bobby,

It sounds like you may have an intermittent power loss or perhaps your
power supply is running low on power? I think I saw this once on my
1200GTO
when the power from my battery was low. After I improved the
connection
from the battery to the mount and kept my battery charged I never saw
it
again.

Subject: [ap-gto] keypad blinking


I noticed a problem last night with the keypad to my AP 1200 mount.
I
have
seen this one other night maybe 2 months ago and none in between
these
2
times. I saw the keypad blink off for a second, then it came back on
but
appeared to be re-booted. It also happened during each of 3 film
exposures.
Each time the keypad would appear to re-boot including the start-up
setting
of 64 for slew speed. However, guide corrections continued at 1x
with
st-4
tracking so it did not mess up the exposures. I would re-set slew
speed
to
1x when starting another exposure but during all 3 exposures it
re-booted.
This sounds like a loose connection but it occurred every time with
the
keypad set down and not being moved or josseled around. Any clues?

Hi Howard,

Since it is the middle of winter it seens unlikely that the
keypad would be able to overheat. I still would double check your
power connection (wiggle it) to see if you get an intermittent
power loss.

Re: keypad blinking

Hi Bobby;

Well I thought I was the only one. My keypad also blinks off but only the
background lighting on the numbers and N E W S pad. I too did not lose
slewing and or tracking abilities, but, just did not wish to bother Marj on
this problem. I thought I wait for that new computer chip which is always
coming soon but never quite makes it...same for version 3.0 on the
digitalsky software.Keep us informed on any other problems.

Re: Roland's polar alignment method

Jeffrey
I see the (star)light now. I was looking for a star in the north around the
side or below Polaris and of course ended up with a much different RA. Your
explanation was perfectly clear. I made it too difficult as usual. Can't
wait to try this method out.
If you go back to the #10 message posted you can see the rest of Rolands
explanation of his quick polar alignment method which is a modified version
of method three in the manual.

I don't have my AP 400GTo yet. So I'd really be interested in learn just
what
you are referring to. No doubt it would be difficult until I actually use
my own
GTO to polar align.

However:

when choosing the star in the North and then South star, what is meant by
similar RA? Since stars in North and South have a great difference in
RA, what stars should I be using here?
probably refers to the local meridian (for example). Lets say for the sake
of
argument it is the end of June. Kochab, beta URSA Minor is near the
meridian. I
am looking north and see Kochab which is at 14h 50m RA. I turn around and
am now
looking south. Also near the meridian is Zubenelgenubi, Alpha Librae. It's
RA is
also 14h 50m. Might that not be what Roland was refering to. Again I have
never
used a GTO (this May I hope!!) so I could be full of star dust...

Re: Roland's polar alignment method

Stephen E. Russell <sjruss55@...>
 

A repost of Roland's polar alignment method (with his permission):

The azimuth setting on the mount is done by picking a star in the
north,
and then slewing to a star in the south at similar right ascensions.
Bring the star half way to the crosshair with the azimuth adjuster,
and
the rest of the way with the buttons. Then hit #9 button to recal the
position. This way, the two adjustment axes are done totally
independently.

Sincerely
Roland Christen
Hello Group

A while back Derek posted this modified polar align method from Roland.
I have a 600 gto and 130f6. I've been using the polar one star method
which is fine for visual use. I decided to try using the other methods
to get more accurately aligned for some astrophotgraphy. I tried
unguided and with first method and anything over 2 minutes showed too
much trailing.
So time to get better aligned.

Using Roland's modified third method to adjust the azimuth, when
choosing the star in the North and then South star, what is meant by
similar RA? Since stars in North and South have a great difference in
RA, what stars should I be using here? In the third method it states to
choose two stars in the East or West with similar RA, this I understand.

As far as orthogonality is concerned, I used that method to see how far
I'm off. AP suggests to shim up one of the mounting rings. I'm using
the dovetail setup. I'm wondering if I might be wasting my time here
since I'm using the dovetail setup. Has anyone shimed up their rings
using the dovetail setup with any success? I figure that you need to
use the flat plate with the rings to keep the alignment. What do you
folks think about this?

Someone mentioned to use two hex wrenches to tighten down the azumith
bolts at the same time so you are not fighting with yourself when you
tighten one side at a time. They also mentioned using nylon washers
under the bolts. Should the nylon washer be used in replace of the
steel washer, or in conjunction with it, either above or below the
steel washer? I'm thinking on top of the steel washer might be best.

Thanks for any input here,
Stephen

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.
 
Thanks for the help...Terry Johnson

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
