Thoughts on DSV, and new upgrade to 2.02.10

Charles Sinsofsky <strfire@...>
 

Hello everyone,
Please be sure to download the 2.02.10 upgrade for DSV, I have improved
significantly the load and startup time from 2.02.09. I did not like the
long wait to start the program, a signifcant improvment should be visible
now.

Another note, I would like some more feedback on usage of DSV, if you
have any notes or features you would like to see, please be sure to use the
User-Comments area on the web site, off the main table of contents. It
permits you to directly send me email about your thoughts etc...

Update on version 3.00, we are closing in finnishing this one. I will be
looking for BETA Testers, it is a MAJOR upgrade with many many new features.
I would like some BETA testers who will provide feedback to me for it.

last note: I am finnaly going to get a chance to add the GOTO and standard
AP listserves to my web site and the A/P web site. sorry delay. I also
completing a email for all AP-GTO users who have DSV and I have their email
to get them notified about this list.

Thank for your time.

600 GTO Instrument Capacity

paul_schroeder@...
 

Hi all -

I have a 600 GTO with the wooden tripod on order with AP (not due until spring,
unfortunately). Initially I will use my Traveler on this (I know the 600 is
overkill), but I plan to eventually acquire an SCT -- of course I might just
succumb and buy one ahead of the 600's arrival.

I do have a quick question for the group. What have you experienced in the way
of SCT capacity for the 600 GTO, particularly when doing any kind of imaging? I
am assuming that an 8" will be fine; will the 600 work with the Celestron 9
1/2"? Is a larger SCT out of the question?

Also, for visual work how large an SCT would be workable?

Thanks for any input and best regards,

Paul Schroeder

Hi,

I currently image with a C11 on an AP600 mount. It is workable with three counter-
weights and a dovetail plate, but I've ordered an AP900 for greater stability. A big

reason for this is that I use a fairly heavy camera (ST7) and a very heavy flip
mirror
(Van Slyke Slider).

For visualy, I think it's great, but I do recommend getting three counterweights.

People have put a C9.25 on a 400 mount on a pier succesfully for
photographic purposes - a C11 on a 600/pier should be fine, and more
portable than a 900.
Just to clarify my earlier response, the C11 works fine on the AP600. However,
it doesn't quite balance in DEC with all my imaging stuff hanging off the back.
The
pier is a great idea, though.

Re: 600 GTO Instrument Capacity

howard lazarus <lazhow@...>
 

Hi Paul;

Ofcourse not always possible, I have a astro pier which does make a big difference.
Using a AP 600 mount I have the AP 130mm and also the Meade 10". I use the special
dovetail plate supplied by AP and the sliding plate supplied by Losmandy all of
which you can get directly from AP.
The wood tripod will not give you the results you may seek in the future and would
consider AP 6" 48" pier...easy to setup but not as pretty as the wood tripod...or if
you have a spot that you can use frequently nothing would beat the permanent astro
pier.
LASTLY, AP SERVICE IS OUTSTANDING..CALL MARJ OR CHRISTINE, TELL THEM YOUR PLAN AND
THEY WILL GUIDE YOU. IF THEY FEEL THE AP 600 WILL NOT HANDLE YOUR NEEDS YOU CAN BE
ASSURED THE HONEST AND CORRECT ANSWERS WILL BE SUPPLIED TO YOU.
Have fun and hope you get you setup shortly...it only took 8 months for me to get my
600.

Win CE?

John Mensick <steadyeye@...>
 

Does anyone know if the AP Go-To software will run under the WinCE
operating system?

The reason this is important is tha it would allow much smaller computers
to be used - WinCE is the Windows version for small handheld PC's.

Thanks, John


Re: Win CE?

Charles Sinsofsky <strfire@...>
 

No, I have though not tried it, the Windows CE platform can not support the
use of the voice system. Though on the other hand, a version of DSV with out
voice might be able to be adapted to the Windosws CE platform. Perhaps I
will look into this after DSV 3.00 is released.

Re: polar alignement,help (long response)

GrayFox65@...
 

Vincent,

Hello from Virginia. Trying to align the AP GTO mounts can be an intensely
frustrating experience until you get the hang of it. In answer to your first
question, no the mount does not have to be horizontal to successfully align
the mount. I made that mistake when I first got started, but "it just ain't
so!" I'm not sure why you aren't aligning successfully, I'll give some
thought to the steps you describe to see if I see anything wrong with them.
Meanwhile, I'm sure others in the group will do so as well.

One thought to keep in mind. Stars located on or very near the meridian (due
South) are very valuable for polar alignment. The reason is that when the
mount is pointed to the meridian, turning the mount's altitude (latitude)
adjuster translates into a purely vertical alignment star motion in the
eyepiece. As the mount is moved to the east or west, a horizontal component
is introduced into the movement of the alignment star when the altitude
adjuster is turned. By the time the mount is laid all the way over to the
east or west, turning the mount's altitude adjuster results in a nearly
horizontal movement of the alignment star in the eyepiece field. Since the
mount's azimuth adjuster always produces a horizontal movement no matter
where the mount is pointed, this can lead to confusion and a seeming
inability to bring the mount to proper alignment.

You may also be experiencing a problem with orthogonality due to the fact
that you are using an SCT on your mount. Others have suggested that it is
more difficult to maintain orthogonality with SCTs than with refractors. If
you use a star diagonal, lack of orthogonality there can be a contributor to
poor performance as well. The AP Maxbrite diagonal is machined to be very
close to true orthogonality.

Having said that, let me offer an alternate alignment method suggested by
Roland Christen, one that works superbly for me. Not only does it separate
altitude alignment and azimuth alignment into separate steps so you can more
easily see what is going on, but it also reveals any orthogonality errors
quite clearly. Furthermore, it doesn't require visibility of Polaris to
work, useful if your view to the North is blocked. I use this method all the
time now, and I can align my AP 155EDF and 600E GTO so well that objects fall
near the center of the field of view of a 3mm Radian, 10 arc minutes diameter
at 365X. Under those conditions, the GTO mount is truly a delight to use.

Here is Roland Christen's method. My amplifying comments are in [brackets].
Note that Roland says he can perform this method in 5 minutes. It take me
considerably longer, but the results are worth it.


GTO Mount Scope Alignment by Roland Christen

I use another method to achieve accurate results, a modification of
method 3 in the manual. [First, use either method 1 or method 2 to get close,
within one or two degrees.] I choose a star that is close to the meridian
overhead, and center the crosshairs on it. [Center the overhead star with the
N-S-E-W buttons and perform a Recal operation.] Then I change the clock time
by 1 hour and enter the same star on the hand control. The telescope now
slews to the other side of the mounting, and the star will be offset in
declination by some amount (the star can also be off the crosshair in R.A.
but this is not due to polar alignment, rather it is due to non-orthogonality
of the telescope vs. the mounting).

To polar align, the star is moved half way to the center of the crosshair
by turning only the altitude adjuster. The star is now brought the rest of
the way with the buttons, and a recal is done by pushing button #9. That in
effect sets the altitude of the mounting. If done properly, you don't need to
do it any more times, but you could do it again by resetting the clock time
to the original hour and slewing to the same star again on the other side of
the mounting. A final fine adjustment can be done the second time. [Ignore
any small displacement in R.A.] You can also adjust the orthogonality of
your mounting by shimming up one of the mounting rings until the star comes
in in R.A also.

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. [Ignore any small displacement in DEC] Then hit
#9 button to recal the position. This way, the two adjustment axes are done
totally independently. It is highly accurate and very fast. I can do it in
less than 5 minutes and be dead on all night long.

Sincerely
Roland Christen

Hello (excuse me formy english)
I want to know if it is important to make the tripod horizontally if i
want to use the polar scope.I have some problem with it.
The precision of my ap 900 gto isn't very good and i dont know why.I
used the next method :
"i choose a star (for exemple deneb) and then manual move the scope to
deneb. then once on deneb i use the telescope hand controller to
select
the star deneb in polar alignment mode and then auto slew it ot
polaris
after i select the star deneb. the scope will slew to polaris, at this
time i use the alt/az only to center polaris as well as you can then i
ask for re-calibrate and i choose deneb again the scope will now auto
slew to deneb by itself, when you reach deneb, then i use the 'hand
controller
key n,e,w,s buttons center deneb in a medium power eyepiece, then
press
goto, the telescope will auto calibrate the new position of deneb and
then
autoslew back to polaris, I repeat the same star 4 or 5 times, then I
choose
another star a great deal of distance away from deneb and go through
that
one 5 times and then I choose another star and do it 5 times and then
I go
back deneb and the precision ISN'T VERY GOOD and i dont understand
why?
What is the problem (celestron 8",horizontally,orthogonality(i have
the system astrophysics made for the celestron 8))

When you are at Deneb for the second time, are you waiting till the scope
reaches deneb, you then use the N,S,W,E buttons, to move the star into the
center of the eyepiece, and then press MENU not GOTO, press the MENU button
to auto-slew back to polaris. I will check the code if you can press goto
and see what happens, but press MENU this will re-calibrate the position of
deneb and then auto slew back to polaris where you will use alt/az to set
the position of polaris, and then either 'next' to exit or goto to re-select
another star or the same star. I use this method all the time for my mounts

Tracking!

RCK <rkuberek@...>
 

The news is good. I was able to train the PEC on my AP600 using the
autoguider on the ST7. The results are appended. The first column is
DEC and the second is RA. The scale is 1.7 arcsec. per pixel and the
total period covered is approx. 12 minutes. The object was NGC 6946.

For the training session I used a tracking image exposure of 2 sec. and
calibration times of 7 sec. and 7 sec. These results for unguided tracking
are far better than I have gotten without the PEC (see my earlier posts).
