Hi Ray,

He plans to view images on the monitor 'realtime'.

It's his scope and he can do what he wants. But I just
drives me crazy when people don't seem to have any
interest in looking through the eyepiece.

-- I will see the 'realtime' results on the PC monitor for both the
-- guidescope and the mainscope in the warmth of my home.

Rich
Now why didn't I think of that? :-)

But seriously, he said he would have two *CCD* cameras, which is not
the same thing as video cameras. And he put 'realtime' in quotes
like I just did. I think he was talking about near realtime. Is
this correct, Terry?

Hi Rich,

I understand why you would think this of someone using their scope
for visual astronomy. But many people purchase AP mounts and scopes to
do Astrophotography. Having done a lot of the focussing and image
taking in the cold, I feel that taking away this discomfort does
not take anything away from Astrophotography. And unless one has another
scope, you can't do any observing anyway since your scope is in use.

And taking your *own* images is far more exciting than looking at a
video of what your imaging, even if the image on the video is better.
Imagine you took this shot of jupiter: :-)

Hi Terry,
 
I recently completed cabling my 1200 GTO mount and SBIG ST-8E camera to a PC
inside my house. I used 2 cables, each 100 feet in length (Belden 8138), one dedicated
to the ST-8E's parallel port, the other is partially used for a couple serial lines to
control the mount (The Sky V5 and DSV 3.0 beta). I also wired a JMI DRO focuser
through the cables so that it sits at my desk next to my computer. I focus my
Takahashi refractor to the nearest 0.01 mm using the DRO and can move the
refractor to any part of the sky
with The Sky or DSV. I control the camera with MaximDL. This sure beats freezing in
the cold waiting for an exposure to complete with nothiong else to do.
 
Recently I did a shot of NGC2024 (the Flame) in Orion with this setup. Here is the
result:
 
 
BTW, I tried a wireless solution and it did not work very well.

Rich, I plan on having a CCD camera attached to the scope and one on the
guidescope. Once I have done the polar alignment process and have focused on
my first object, I plan on using a wireless two-way communications
environment to communicate guiding and focusing commands to the scope. I
will see the 'realtime' results on the PC monitor for both the guidescope
and the mainscope in the warmth of my home.

The motorized focuser allows me the hands-off environment after inital

Hi there,

I will be receiving an AP130F6 refractor with a 2.7" rack and pinion
focuser and a 600EGTO mount in January/February. I would like to add a
motor drive to my focuser that I can control with my 600EGTO mount

available. I know Meade makes one as does JMI. Are there others? Which

Hi Terry;
first congratulations on your 130 and AP 600 mount. First of all it will
take you some time to get adjusted to the alignment process that is required
on the AP 600. Expect to spend hours before you reach the stage of
satisfaction. VSE makes the best, most expensive and the most overkill of
any focuser on the market today. A pure waste of equipment since there is no
image shift on the AP 130 and a pure waste of cost.For the $495 plus $195
for the adapter that VSE charges you can get many other items like
eyepieces, solar filters etc that will add to your enjoyment . Lastly you
need this focuser like a hole in the head. The AP rack and pinion devise
will give you the perfection you seek. Rich N is totally correct.

Re: wireless two-way communications to a PC

Charles Sinsofsky <strfire@...>
 

I have been talking with Terry in email, but I thought for the use of the
group here I will post some info.

For a totaly wireless solution for using DSV with your mount, I suggest the
following:

1- obtain a set of wireless headphones, these could be like the type from
radio/shack. they can easily be adapted to the output of a given laptop or
desktop.

2- obtain a wireless mike from shure, highend, or a radio shack type
wireless mike.

use both units at the same time..ie: allows for input and output of the
sounds/words from dsv.

I am currently looking into finding a 'single' type headset for the both
microphone and earphones with use of a single full-duplex transmitter..will
update about that later.

I have also created a new section on the web site about microphones and
will be expanding it to become a hardware area. detailing what over the last
6 months etc..have learned concerning various hardware used with dsv, with
respect to various sound cards, laptops, desktops, etc.. and what are good
mikes, what are good headphones, headsets..etc.. look for this area to grow
over time.

Thanx for your time

LRGB Image of M42 with AP600 GTE Mount

RCK <rkuberek@...>
 

Hi Goto'ers

This image I took with the 4" AP Traveler at f/6, using the
ST8 NABG and CFW8 color wheel from my back yard
last night. While it does not approach Robert Gendler's stunning
image in scale or resolution, there are some rich colors and
nice detail.

http://sciastro.net/flashca/index.htm

M42 is sort of a difficult object because it is so bright. For this
reason, I used short (30) exposures and imaged in track and
accumulate mode. To get decent tracking I again tried the trick
of training my PEC using the guider in the camera. After training
the PEC on field star near Hamal, here's the track list (M33):

ST-8 Track List
Version = 1
Snapshots = 10
Snapshot_time = 30.00
Temperature = -5.23
Height = 1020
Width = 1530
Offset = 0
0,0
-1,0
-1,-1
-1,-1
-1,-2
-2,-2
-2,-3
-2,-3
-2,-4
-2,-4
End

Exposures times were 30 seconds per frame with 30-45 sec.
per frame for readout.

The pixel scale for this was approximately 3 arcsec. per pixel, so
the total drift (due to polar alignment error) was only 6 sec. in
RA and 12 sec. in Dec. But more importantly, the the periodic
error was almost negligible! Measured guide errors during autoguiding
were consistently sub-arcsecond. I highly recommend this pro-
cedure.

The headset I use is an AKG professional musicaians headset, around 500.00

It also uses a battery powered amp that the mike is plugged into.
Unfortunatly I can not remember the actual model number, it is at home and I
am at my office while I write this. While I feel this is a excellent
headset, it is 'over priced'. I originaly bought it because in the early
days of showing off DSV I had no real idea what type of mikes would work and
what would not...this headset is part of my equipment set that I used when I
first EVER showed DSV at the StarFest convention some 4 years ago.

The two mikes listed are OK for crooning if you want to mimic Don

Hello Vicent,

First you should email me or A/P directly for this type of thing. It is
VERY unusal for A/P to make a mistake like that via shipping. ie: to forget
a manual. I see to it that another one is sent you way my friend.

To all others DSV has to include the users manual, because the package
that it comes in requires it.
