Power

rck <rkuberek@...>
 

Well I've done it. I just fried the control box for my Dew Zapper.

In my never-ending quest to get a reliable DC power source
that gives at least 12V to my AP600 mount, I got a Samlex
regulated power supply. Testing it with the Dew Zapper, I found
that the the voltage off the power supply drops from 13.8 to
13.0 when the Dew Zapper pulses. This should be ok for the
mount on the same circuit, and so solves my problem for back-
yard use, if not for field use. However, I shorted my Dew Zapper
while testing and now it's dead. Doesn't seem to be fused. Now
I don't have a problem anymore.

Regards,
Bob K.

If there is any way you can see your way clear to hanging on to that
600E, PLEASE do so. The creature will not mind waiting for your
attention. Just store it like an old Harley and you and your boys will
be glad you did. Look on it as a season. Its season simply has not yet
arrived but it surely will.

Get that interim telescope, that's a good idea but we are far to quick to
part with things that are fine.

Trade for Teleport?

paul_schroeder@...
 

Hi all -

I have an AP 600E GTO that (sad to say) is getting a bit too lonely.

When I ordered the mount last year, my intent was to get into imaging with my
two sons (ages 10 and 13). However, when I ordered the 600, little did I know
that things would be changing a bit for me.

The mount arrived in March this year, and my new baby daughter arrived in April!
You can guess which gets played with the most . . . (actually, it _is_ my
daughter!).

I really like my 600, but I also know that it won't get the use it deserves
(particularly for imaging) for several years. It seems a true shame not to put
such a fine instrument to use for its intended purpose.

As such, I am considering trading the 600 for something that would get more use
(I'm don't want to sell it outright). The once scope that would be most
appealing would be a 10 inch Teleport -- the quick set-up time would really
complement my very time-limited observing sessions. If anyone has a Teleport
and would be interested in working a trade for a mint condition 600 GTO (plus
cash to balance things) please let me know via Email.

Thanks and best regards,

Paul

The learning curve takes about 1 night. It's very intuitive. Read the manual
and run the mount no muss no fuss

One evening is all it takes... if you read the manual ahead of time.
It is quite intuitive and the controls are organized in a fairly
straight forward and logical manner. But it will take a few more
evenings until it becomes second nature.

There is, however, another question: how long will it take for you to
get an AP GTO mount <g>?

I'd also recommend a good planetarium program. My personal favorite
is "TheSky," by Software Bisque. It is extremely veratile and very
useful in both planning your session and in locating the targets you
intend to image. Digital Sky Voice is a nice program too... and will
center you on target, but I prefer the former.

Depends on how well you know the ins and outs of mountings. We give you all

Re: Sony Notebook and DSV.

Hi Marc.

I have been dealing with Sony tech support to get DSV to work consistently
with my Sony PCG Z505SX notebook. While we have found some ways to improve
the situation by modifying the system boot, there are still some problems
with the Sony sound card freezing up after extended use and when the laptop
lid is closed. I'll let you know if we find a fix that works across the
board. I don't know if other Sony notebook models have the same problem.
I'd note that DSV works flawlessly on my Sony desktop, so it is clearly not a
problem with all Sony computers.

Best regards,

Re: 400 GTO RA "Lock Down" procedure

Ron Wodaski <ronw@...>
 

Sounds like you are really referring to the Altitude and Azimuth
adjustments. The two vertical bolts on the AP 400 tighten down your azimuth
adjustment.

I discovered Mylar washers, which are very tough and low in friction. I
originally installed them on my AP 600 to deal with a similar problem, and
they work just as well on my AP 400. With the Mylar washers in place, I can
tighten the two bolts that lock down the azimuth adjustment, and still move
the mount using the two hand-screws. This has given me much better polar
alignment with fewer iterations.

Please see my web page to see how/where the washers are used on the AP 600;
use on the 400 is similar:

http://www.wodaski.com/wodaski/ap600clamp.htm

Folks seem to have a hard time finding these Mylar washers, so if you can
find them, I bought a bunch locally and can send some to you; details are on
my web page.

I find that when I tighten the RA axis after/during polar alignment that the

When I am centering Polaris, I will alternate the between the left and right
lock down bolts. this will move the RA "back and forth" and I was pretty
successful in getting Polaris centered after getting both bolts tight.

I have not yet performed a drift alignment procedure. How do you deal with
this "problem" during drift alignment?

Do I need to have these bolts very tight to assure that the RA axis will not
"slip" out of alignment?

What about the Dec axis? I have yet to tighten that bolt.

Chuck,

oops! A little mix-up in my terminology there! Sorry about that.

Yes, I am talking about the Alt/Az adjustments. I kind of figured that the
lock down could act as the fine adjustment. I just wanted to confirm that
others are doing this the same way.

Thanks!

You must be talking about the Azimuth axis and the Altitude axis, and

with the AZ. knobs, why not do the final fine increments with the

locking knobs don't have to be gorilla tight anyway.

How would these affect drift alignment? If you are accustomed to making
fine adjustments with the Az. with the locking bolts, then it should
work fine. Small adjustments are what you are after anyway.

Re: 400 GTO RA "Lock Down" procedure

Terry Johnson <tjohnson@...>
 

Mark, I have had the same problem with my 600GTO mount. I have solved the
problem in three ways:

1. -When you have completed making your adjustments in RA, make sure that
both of the RA adjustment knobs are tight against one another. This helps
prevent the mount from moving when you tighten the mount screws (hex bolts)
that hold the mount down.

2. -When you loosen the mount screws, you do not have to loosen them very
much. The less you loosen them the less movement you will have when you
tighten them.

3. -I have found that after I have tightened the mount screws, I can still
make fine adjustments to RA with the adjustment knobs.

Hope this helps...Terry Johnson

Negative facets are the modem that, while V.90 & K56flex rated,

at 56K (57.6K indicated) with the hardware based ISA modem. I'm also
not fond of the speakers. Hah! It's a wonder they even bothered; they
are impervious to the elements and all, but are so darned dweeby that
you can hardly hear anything from them. I usually use some small Sony
amplified speakers to get enough volume. Otherwise it seems to fit my
requirements pretty well... or so I say until I back the car over it,
and find out it's not as togh as I thought it'd be! =:O
