Try David Butler at Master Cases 888 707 9333. They made awesome cases for
me. They are approved for air travel, but who would put a 1200 on a plane?

My very appreciative thanks to both Charles Sinsovsky, and Roland

past weekend's Astrofest. While i didn't catch the assembly in time,
the dissasembly let me see firsthand how truly portable, and
compact/Lightweight (relatively speaking) the 1200 is. After
owning the
HGM-200 Losmandy, i will find the 1200 an absolute pleasure to set-up,
and use. IMO, this is the finest mount that i have ever laid my
eyes/hands upon. Hope the wait isn't too much longer! :) Mark

Can't adjust speed when aligning

Marj <astrophy@...>
 

Paul and all GTO users,
Here is an updated version of the changes made thus far to the firmware in
the keypad and the chip located in the servo box. Charles is working on a
few enhancements and minor fixes in the keypad software which will be v2.6
when finished.

If you want to upgrade to v2.5, you have two options. If you can't wait,
send the keypad into Astro-Physics and we will reprogram it. Since we have a
new version in the wings, I recommend that you wait for our internet
download from our web site which we are planning to have in October. In
order to accomplish the download, you will need a new chip in your servo box
(we will probably charge about $30 to cover the cost of the chip, extraction
tool needed to remove current chip and shipping). These will be available in
October also and can be easily installed by the user. Then, you will be able
to upload all future upgrades to the keypad firmware from our web site
without further costs. This will make it easy for all.

UPDATES TO KEYPAD AND SERVO DRIVE CHIP
KEYPAD REVISIONS
After 6-22-98
Fixed PEM and added timer
Fix save of Dec backlash
Complete safe zone with save
Change set site location - took negatives out, added W-E and N-S (the
minus zeros were a problem).
Fixed ADS separations
Removed "size" from object data since most objects are irregular and this
data was not loaded
Fixed RA/Dec entries involving minus 0
Activate park function
Added current position function to NEXT button at Objects Menu
Reorganized and corrected search function
Recalculated lunar position (later determined this was incorrect)

7-13-98
Corrected lunar position calculation
Change focus default setting to Low to correspond with TheSky

7-15-98
Removed Display Time/LST from Setup-2 menu
Add RA Backlash to Setup-1 menu (new function)
Moved Reticle adjustment to Setup-2

7-16-98
Add N-S-E-W button function to Cal. Menu when star choice data is
displayed
Prevent observer from using N-S-E-W directional buttons in Center Polaris
screen
Put Focus selection in #2 spot in Setup1 so that people don't accidentally
change the backlash setting which was in #2 spot

7-18-98
Fix PEM (timer was not going off consistently)

7-21-98
Increased backlash compensation for 400 & 600E mounts

7-29-98
Fixed planets menu, which used to skip #1 and begin w/# 2 (if you pressed
1 accidentally, you got gibberish). Now #1 works properly for first
selection.

8-25-98 - version 2.1
Fixed sign of declination number of Southern Hemisphere objects from +
to -. Used to show + sign when displaying RA/Dec coordinates prior to go-to
action.
Will now go to objects between 0 and -1 latitude.
Save position of common object names in Tours menu. When you go to a
common object from this menu, then press Menu, the display will return to
the screen that shows the last common object you viewed. If you go to other
objects using other menus (Search, M, etc) then return to common names menu,
the display will show the last common name object you viewed. Previously, it
returned to the beginning of the common objects list each time.
Save position of Stars/Constellation in Tours menu. When you go to a star
in a chosen constellation, then press MENU, the display screen will return
to the same constellation and screen as previous entry. Previously, it
returned to the first screen of the constellation with the alpha star.
Save position of Objects/Constellation in Tours menu. When you go to an
object in a chosen constellation, then press MENU, the display screen will
return to the same constellation and object screen as previous entry.
Previously, it returned to the first screen of the constellation with the
alpha star.

9-15-98
Corrected remainder of objects that have -00 latitude (these had +00)

11-2-98 - version 2.2
Allow user to change button rate at five additional places in the program.
Pushing "+-" button brings up screen that allows you to change button rate.
Button rate can be changed when you are in these functions: "Pick star"
screen in startup procedure, 'cal star" screen in startup procedure,
"objects menu" screen, screen that displays after you slew to an object,
RA/Dec coordinates display that is accessed by next button after you slew to
object. These are places that the user is likely to need this feature. The
screen displays "guide speed: <rate> x", rates are from .25x through 1200x.
Toggle through the selections using Prev< and Next> buttons.

11-12-98
Reword screen that comes up when push "+ -" button. Used to display, i.e.
"guide speed: 64 x", now displays "button rate: 64x".

01-14-99 version 2.3 (actually downloaded in mid-December)
N Polar Calibration routine changed. Previously, the user had to manually
move the telescope to the next calibration star, and then the scope would
slew back to Polaris. Now, the user moves the scope manually to the first
star, then all subsequent movements are automatically slewed with keypad
controller. Each time you use the N-S-E-W buttons to center a star, then
press Menu, you recalibrate.
Two Star Calibration routine has been simplified. Probably easiest to
compare instructions to see the differences. Now the user goes to a star and
makes adjustments halfway with N-S-E-W buttons and the remaining half with
the alt-az adjusters. When the user selects Menu to exit, the mount
recalibrates and you can either go to another star or exit the program.

01-30-99 version 2.4
Revised park function to include Park 1, Park 2 and Park 3. When you
select one of these park positions, the mount auto-slews to one of the
following locations: Park 1 - the scope will be level and pointing north.
Park 2 - the scope will be level and pointing east. Park 3 - the scope will
point to the pole. You can use the Park 1 position (also called reference
park) with a bubble level to polar align your telescope in the daytime or
when you can't see Polaris.

06-02-99 version 2.5
Park functions work correctly in Southern Hemisphere.
Improved declination backlash range for 400GTO.
Prevent user from bypassing Startup routine in location selection and Cal.
Menu screens. In previous versions, it was possible to press MENU and escape
the Startup, however then the mount was not calibrated.
If a user still manages to bypass the Startup routine at the Cal. Star
selection screen by pressing MENU, the keypad will send the data for the
reference park position (see the manual for discussion of this postion).

SERVO DRIVE BOX REVISIONS - Chip Program
7-9-98
Solved 80% of problem - if slew with buttons to various areas of sky, the
mount gets lost when asked to slew to object. Just two areas remain that are
below mount in areas not likely to slew to.

7-16-98
Can slew anywhere in sky with buttons and mount knows where it is (used to
get lost if you were pushing N-S-E-W buttons to guide across the meridian or
when scope was below mount).
Made adjustments to allow correct movement (motors and slewing direction)
in southern hemisphere

7-17-98
Fixed PEM (was not recording properly)

10-30-98
If motor stalls more than 1 second, the drive will shut off. This is a
safety feature to prevent motor burnout in case of severe load on the motor
due to an extreme imbalance condition or if the power to the mount has been
accidentally left on and the scope has hit a hard stop.

12-18-98
The telescope can now be placed in any of 3 park positions, the power
turned off and the keypad removed. When the power and keypad are restored,
the mount will stay parked and not resume tracking until the Resume from
Park function has been entered on the keypad.

Note: We recommend removing all power cords from the mount and/or from the
wall socket to prevent damage from direct lightening strikes.

5-13-99
Horizon check - This function is normally used from the keypad. Added it
to the chip so that people who are writing software will have access to this
command code. Commands:
:ho# means on
:hq# means off
Fix communications interrupts that caused a problem when using DigitalSky
Voice and TheSky software together. This problem occurred with version 5
of TheSky.
Provides ability to download new keypad versions from our web site. This
has been tested in simulated download, but not an actual web download. This
part of the code may need revision before finalized.

07-29-99
Initialize the COM ports twice to be sure they can establish communication
consistently.

08-09-99
Allow recalibration during PEM playback without extraneous motion.

Subject: [ap-gto] Can't adjust speed when aligning


When polar aligning, a constant frustration for me is my inability to adjust
the N/E/W/S button speed when centering the alignment star. No matter what
speed I pick at the initial screen, as soon as I enter the alignment
routine, the button speed increases and makes getting the alignment star
centered very difficult. I'm tired of shooting back and forth and back and
forth until I finally get the star close to being centered.

Am I being obtuse? It's probably something simple I'm missing, but I can't
find it. Any help would be greatly appreciated.

BTW, did anyone else see the shadow transit this morning, right in the
middle of the GRS?

As to changing the button speed, remember there is a somewhat

when ever you can press the buttons say at alignment mode, you
can press the
'+-' button to bring up a special hidden menu that allows you to
adjust the
button speeds from the slowest to the highest by pressing the next and
previous buttons then press the 'menu' button and you will return to exact
position you left off but the hand controller buttons will now slew the
scope much slower or faster if you like.
To Charles and everyone else who responded, I am grateful for your help.
I'll try it next night out.

A speical feature is coming for 2.6 that will permit you to use the a/p GTO
mount to think the zenith is not at the center or top of the mount, but
rather offset by a user selectable amount, say 4 hours, that way the mount
will not autoswitch sides when requested and thus you can effectivly stay
on
one side for much longer.

All will be explained with the release of 2.6 ..I am finnishing it up now.

This post is a cross-post with the AP users-group. Both it

both hoping to get a faster response.

I've been told that there is a way to re-set something, probably
the time, so that one can avoid twirl around to the other side
of the AP GTO mounts. I realize the reason for this is to avoid hitting
the
OTA
into the pier or tripod, but my goal is to be set up shooting for the
western side
of the mount when starting a long exposure. Right now I am shooting 3
hour exposures of the cocoon nebula (ic 5146) and for the first exposure
early in the night the mount will slew to the eastern side. (OTA on the
west
side looking east)
Near the end of the exposure it gets the tube very close
to my pier. If I can start this exposure some way
on the western side (OTA on the east side looking west)
then my problem will be fixed. I once had the fix for this in my
files but a computer crash fixed that!

Re: AP 600E Polar Alignment Question

Charles Sinsofsky <strfire@...>
 

The polar alignment routine using 4 stars ie: using the n-polar aligment
mode with at least 2.4 firmware will not require you to move the scope by
hand anytime, other then the inital pointing, but will permit you to get
VERY accurate polar alignment. I have done 35 mins unguided prime photos
with my 1200 using my polar aligmnent routiens with 4 stars and medium to
high power eyepiece., I use deneb, vega, arturaus, and sometimes a variety
of stars for the fourth one. remember the key here is repetition, ie: go
back and forth between the selected star and then the next and the next, and
then start al over again, I do the whole sequenece oin this form. first star
choosen 4 times back and forth from polaris autoslewing and thne second star
4 times etc... and then I do this same to all the way to the 4th star or 3rd
star and then I start all over again with ther orignal 1st star. I do this
proces 3 times, by the third iteration the stars always fall dead center all
the time. perfect polar alignment.

Hi Jim:

Method 1 suggests a star greater than +/- 4 hrs RA from the
pole Why in the first method of polar alignment does the manual state
that Arcturus is not a good star for aligning since it is too close to
Polaris in RA? Polaris has an RA around 2 H, Arcturus is around 15 H,
what am I missing?
Perhaps Charles could comment, but I think what the manual should state
is that the best alignment stars should be 4-8 hr. RA from the pole,
preferably at declinations below 0. Arcturus is nearly opposite Polaris
(close to 12 hrs. away) and would take several iterations to work
properly.

Previously, Charles indicated that a new two star alignement would be
available which sounds very promising.

Would anyone volunteer any method to get a closer polar alignment
besides Method 1? Every time I try to align and try to refine via an
additional iteration as stated in the manual, it doesn't get much
better. Can anyone help?
Get the polar alignement scope--it's the easiest way.

Also, check your orthogonality.

Re: Can't adjust speed when aligning

Hello Everyone,

Sorry I did not respond to these questions right away, I have been VERY
busy with DSV 3.0, the upcoming downloadable Hand controller code. a new
chip will be required for your mounts but you will all be able to use thew
web site now to download the hand controller code as I bring it out. 2.6 is
well on the way to being completed.

As to changing the button speed, remember there is a somewhat hidden menu,
when ever you can press the buttons say at alignment mode, you can press the
'+-' button to bring up a speical hidden menu that allows you to adjust the
button speads from the slowest to the highest by presssing the next and
previous buttons then press the 'menu' button and you will return to exact

i have some problems with the precisions of pointing of the mount.
When i press Rcal to recalibrate on a star (for exemple deneb) then i
can slew to another star (for exemple polaris).Polaris is away of the
center of the ocular.If i press Rcal 3,4 or 5 times (with different
star) on the same night then i slew to polaris,i can't see polaris
with the ocular:the precision is decreasing!!!
What's wrong,orthogonality or else?
Is the horizontality important with the polar alignement scope?

Re: AP 600E Polar Alignment Question

Derek Wong <dawong@...>
 

I have the polar alignment scope but I have not installed it yet. I
understand that it first needs to be aligned coaxial with the RA axis
then it can be usedproperly. Any tips on getting it coaxial?
There should be some instructions, and I poseted my thoughts on message
#2 of this e-group.

I have a
lot of trees in my back yard and can't sight a far away HV insulator.
Could it be aligned at night?
I think it would be very difficult. Perhaps you can set up during the
day in front of your house just to align the scope--then you could sight
something far away.

Also seems confusing on the polar reticle. What stars correspond to the
reticle marks? It's not clear from the documentation.
If you look at a map, it is confusing. Alpha, Delta, and Beta
correspond to Polaris, Delta Ursae Minoris, and Beta Ursae Minoris
(sorry, I forgot their common names). When you look through the scope,
turn the axes so that Polaris and Delta are in their respective
circles. The dashed line will point toward Beta, which is out of the
field.

If you look at a map, the angles don't match--the reason is that the
polar scope is a refractor and the image is reversed. Since you are
looking at the Alpha-Delta line directly through the scope and the
Alpha-Beta line naked eye, this illusion is created.

Anyway, good luck--my illuminator just went out, so no polar alignment
for me!

is that the best alignment stars should be 4-8 hr. RA from the pole,
preferably at declinations below 0. Arcturus is nearly opposite Polaris
(close to 12 hrs. away) and would take several iterations to work
properly.

Previously, Charles indicated that a new two star alignement would be
available which sounds very promising.

Would anyone volunteer any method to get a closer polar alignment
besides Method 1? Every time I try to align and try to refine via an
additional iteration as stated in the manual, it doesn't get much
better. Can anyone help?
Get the polar alignement scope--it's the easiest way.

Also, check your orthogonality.

Re: Can't adjust speed when aligning

Philip Perkins <philip@...>
 

When polar aligning, a constant frustration for me is my inability to adjust
the N/E/W/S button speed when centering the alignment star. No matter what
speed I pick at the initial screen, as soon as I enter the alignment
routine, the button speed increases and makes getting the alignment star
centered very difficult. I'm tired of shooting back and forth and back and
forth until I finally get the star close to being centered.
Paul, I think this is a known bug. I have a very similar thing with
version 2.4. Except that I steer well clear of the iterative routines,
which are hopeless unless you have excellent orthogonality of the optics
with the mount. I notice the same thing when I do a Recal (button 9) - the
star veers off in an RA direction and the guide speed changes. That, I am
afraid, is a bug. Charles said that it was being fixed in 2.5

to my pier. If I can start this exposure some way
on the western side (OTA on the east side looking west)
then my problem will be fixed. I once had the fix for this in my
files but a computer crash fixed that!
Thanks for any info,
Hello Bobby
You can set the time plus or minus from the correct local time, which has
the effect of moving the meridian where you want in the sky. I use 2 hours
offset quite regularly, sometimes up to 3. It works very well - just be
careful not to hit the pier, but you know that one already.
