Re: HELP!!! (was Keypad intensity)

Marjorie:
I have the same problem that Paul has, the display of the handpad of
my 1200 GoTo can be barely seen in the Low Mode, at daytime you have
to get the handpad under a cloth even when using the High Mode. I
would like to know if there is a chance that I could change the red
filter for a lighter one and if you can provide me one, or preferably
if you will be attending RTMC, I could take the handpad there so you
could change the filter. My problem is that it is very difficult for
me to send the handpad to the U.S.A., and then to get it back to my
country.
Probably this can be of interest to you Marjorie, I also own
a "Gemini" goto system for the Losmandy mounts, the unit has a vacumm
fluorecent display like the one in your handpads, but this one can be
dimmed in several steps from 100% to 32%, this display at 100% can be
seen in plane sunshine, at night you can use the 32% setting very
well.
I send my regards to you, Roland and Christine.
Eric.

The display on all the keypads is a vacumn fluorescent type. We

because of its extended temperature characteristics (rated to -40

in the
daylight without shading it.

We considered other possibilities, but were not pleased with the
performance
in cold weather- dim and very slow scrolling. We felt this would a

The only differences between early and later keypads is the actual

Re: Ascom driver for AP Goto mounts

Mark Jenkins <markj@...>
 

Why are you sorry you asked? I find nothing about Roland's comments
demeaning to you.

I think the question should read:

Has Charles implemented or is he planning ASCOM compliance with DigitalSky
Voice and/or DigitalSky Image?

DSV and DSI would be the targets for ASCOM not the mount itself.

Just trying to help.

I believe you misunderstand the purpose of a goto mounting. The
script would
control a planetarium program which in turn would move the mount.
Without the
planetarium program, the mount will not move on its own. In other
words, you
cannot send a command to the mount to "goto M42" . The mount just
simply does
not understand this sort of command. All scripting can do is to
command a
computer program (planetarium program) to ultimately tell the mount
where M42
is by sending an RA and DEC command per the AP protocol to the
servo box. Is
there something here that you do not understand? Do you understand
the
difference between a mount servo and a planetarium program? And, of
course
you can control the mount via a scripting program, you need to add
a
planetarium program in the loop to actually command the mount to go
somewhere. So what are you suggesting that the scripting program do
differently?

Hi Marj,
Indeed it is much more important to have the display work as well as it does
in sub freezing temps.
Besides the black hood that Gus mentioned, I will wear sunglasses while
setting up. I'll still take a look at my friends keypad to see what if any
difference there are. Thanks for the explanation.

I also have an earlier one #636 and like Gus it is almost impossible to read
the display in the daytime when solar observing. I tried using a box to
shield the light and only after my pupils dilated, then I could just barley
read the display. The dim mode is just fine for me a night, I too just wish
the bright mode could be readable in the daytime. It's usable but my pupils
don't adjust from bright to dim light near as fast as they used to so it
takes awhile to get set up in the daytime.
My friend has a newer (last April) gto, I will have to compare his display
to mine next chance I get.
The black hooded cloth sounds like a good idea, thanks for the tip.

Hi Roland,

Yeah... I thought it was the normal intensity, until I compared it to
the new one. The serial nos. are 842GTO on the dim one and 1091GTO on
the new one.

As soon as I powered up the new unit it was "WOW... I can SEE the
display"! I'd sure like to have the same level of intensity in the
other one. Is there any hope?

I'm not sure what you mean by Ascom compliant driver? Can you
explain what
that would do? Remember, the GTO mount is not a planetarium
program. It's
only function is to accept RA and DEC commands per the AP protocol
and move
the two axes accordingly.

I have. It doesn't. Hence the question.

Denny's program goes into the Meade data base, extracts the necessary RA and
Dec co-ordinates for the object being requested from the user, and then sends
the RA/Dec info back to the mount, which in turn causes the mount to move to
the desired location. Denny's program is Ascom compatible. Basically he has
developed a program to control the Meade mountings, a driver if you want to
call it that. Note, the Meade mounting itself is not Ascom compatible. The
external computer program which uses the Meade protocol is the thing that's
Ascom compatible. The Denny program can be scripted, the Meade mount itself
cannot be scripted.

Denny has not written a program for the AP mountings. I do believe that there
are several planetarium programs which are Ascom compatible, and which can be
used to control the AP mountings. The Sky is one, I'm sure there are others.
In this mode, The Sky can be called a driver for the AP mounts, unless I am
totally mistaken by the term "driver" as used in your original question.

Charles' Digital Sky Voice is not at this point. It was developed as a voice
program, and I don't know how much effort would be required to make it
scriptable. There really is no need to since there are plenty of planetarium
programs that can be scripted.

I received my 600 mount last year, and always wondered why the
display (even in the bright mode) was so dim. Last month I took
delivery on a 900, and the keypad display is much brighter (I
plugged both of them into the same battery supply together to
compare). In the dim mode it is about as bright as the other
unit's bright mode. My 600's display is difficult to make out
until full darkness has set in.
Hi Nick,

Thanks, but that's not the problem.

I have two AP mounts and two keypads. The bright mode on the first
one has been dim since I got it, and the dim mode is practically
useless.

It wasn't until my second mount was delivered that I realized things
really were amiss with the first keypad, as the display on new one is
much brighter... the dim mode on it is as bright as the bright mode
on the first one. Both are the latest revision and are otherwise
identical.

Before I had the second keypad to compare it to, I thought:

A) I must have a brighter site than most AP users (actually, my rural
site gets pretty dark).

B) My middle-aged eyes are worse than I suspected (Phew, not the
case... YET!).

Help? Anyone?
