Rick, I'm using Ultra VNC - it worked pretty well out of the box and was free.

When setting up your "N" network between scope laptop and house
computer did you use PC Anywhere program or how do you access the
screen and run the "scope software". I'm wondering how you do the
computer to computer networking. Thanks.

Slaving with MaxDome I

Arthur M. Schneiderman
 

Can anyone tell me the correct setup parameters for an
AP1200GTO/AP155EDFS in the Dome and Telescope Setup screen in
ASCOMDome? My mount is at the center of a 7.5' diameter Sirius Home
Model observatory.

I tried determining them, but the opening does not line up with the
telescope. The MaxDome instructions are not very clear in defining
the reference points of the required measurements.

Help most appreciated.

Re: rs 233 to USB conversion

Arthur M. Schneiderman
 

I'm more than a little leery of the wireless solution so I took a
different route:

I ran a cat5e cable from my in-house router to my observatory. At the
observatory, I have a digi AnywhereUSB box that allows up to 5
attached USB devices to be transparently accessible from any PC on the
network. Attached to the AnywhereUSB is a digi Edgeport/421 that has
1 parallel, 2 rs232 and 4 USB inputs and one USB output that is
connected to the AnywhereUSB. I also have a digi Edgeport/2c attached
that provides 2 more RS232. So I have a total of 7 USB, 4 rs232 and 1
parallel available.

You may think that that's overkill, but I'll be using all 4 of the
rs232's: 1200GTO, MaxDome, Clarity I, STV from the start. If I need
to add more, I'll just go back to digi (www.digi.com).

I'm adding a Ethernet switch in the observatory so I can simply plug
my laptop into it into the switch when I'm working in the observatory.
It will also allow me to add ??? over IP devices when needed.

Hello to All,
I'm new to the ap 900 mount and astronomy. Mount works fine, but I
now want to utilized the remote control software of my laptop. The
laptop will be approximately 100ft away from the ap 900 gto, and I
realize that I will have to do a rs232 to USB conversion. Is there a
list of components and their manufacturers which will allow me to
control the mount from that distance?
I am not sure how all of the components will go together to make
this work. I currently have windows xp ver. 2, but no rs 232 port on
the laptop. Starry Night pro ver. 6 and pulseguide software
Any help and direction will be appreciated.... Thank

I use the new Apple Airport Extreme N router (replaced my old Apple
Airport Extreme-snow). I then used Timbuktu to communicate with the
IBM laptop connected to my scope via the LAN IP address. Hope this
helps. Works fine to about 100 feet or so. Nice to have wireless
but requires a laptop at the scope. The CAT 6 arrangement eliminates
the laptop at the scope, extends the range to up to 325 feet but
requires the one cable. Hope this helps.

Thanks for the report, Dick.

I was hoping for the other answer, though. It would just be that little

Re: rs 233 to USB conversion

Joe Zeglinski
 

Hi Stuart,

I think you need to go into the Firewall program (Norton?), click on
Norton Protection Center's Personal Firewall, select configure.
Choose Networking tab, click on ADD, and then the button, "using a range" -
set your router address range start & end, to include your laptop and any
other devices served by your router. I just set it for all 255 devices, in
case I add something in the 100 range, or below it. I just trust all addresses
behind my router.
I did this with my WRT300N as well.
Every time I reinstall Norton, I always forget to do this last step.
Otherwise, the computers can't see each other or share folders, on the
internal wired or wireless LAN.

The reason your workaround works is that Norton's Firewall doesn't have
the WRT300N's range configured, so the laptop is locked out when it tries it's
initial connection. Don't understand why it then works after that, though -
Norton should still lock it out. Maybe it's just an initialization step that
needs this.

Anyway, set the range, and you won't have to fuss with it until the next
time you reinstall Norton.

Hope this helps,
The other Joe (Z.)

Joe, in case it helps, I'm using a Linksys WRT300N wireless-n router and a
Linksys WPC300N wireless-n Notebook adapter (PCMCIA card). My observatory
computer has W2000 Pro on it and the house computer has Vista. Setting up
the home network is kind of "follow you nose" but what I found I need to do
each time I start up the observatory computer is to turn off my Personal
Firewall in Norton for a few minutes while the network gets established and
then everything behaves.

Hello Stuart. I agree, If you want to go totally "wireless" you need to
have routers and laptops
running in the "N" mode to get decent response. I've used this setup with
Timbuktu remote
control software and all works easily.

But.....if you want better performance and 150-200 foot range or better use
an Ethernet to
USB bridge box. For about $100 you can get a 4 port USB box to velcro to
the side of your
tripod or mount. This allows you to connect several USB devices such as:
the mount (with
serial to USB converter-$20), the CCD camera (mine is already USB), a
remote focuser such as
Robofocus, etc. I have a four port so I can run all three and still have
one extra.

Then just run a single Cat6e cable (150 is relatively cheap on line) and
connect it to the USB
box on the scope to the receiver box (USB to computer) attached to the
computer.

Then you can run everything without the usual interference glitches. This
is only one
alternative to going wireless but certainly is easy and FAST.

tripod or mount. This allows you to connect several USB devices such as: the mount (with
serial to USB converter-$20), the CCD camera (mine is already USB), a remote focuser such as
Robofocus, etc. I have a four port so I can run all three and still have one extra.

Then just run a single Cat6e cable (150 is relatively cheap on line) and connect it to the USB
box on the scope to the receiver box (USB to computer) attached to the computer.

Then you can run everything without the usual interference glitches. This is only one
alternative to going wireless but certainly is easy and FAST.

Let me know if you need pictures or part numbers

RS1300rs I'm looking to going the wireless rout too. I use GoldeX Serial to USB Converters into a 4 Port ICRON which converts to
Ethernet for a 150ft run. Last year I lost the inside ICRON box and CAT6 cable because of a ground induced surge picked up in
the underground cable run. I'm quite interested in converting to wireless to eleminate surge potentials. What Router Model/s
did you use, and were they affected by IR window film people have been talking about? Thkx...joe :)

Hello Stuart. I agree, If you want to go totally "wireless" you need to have routers and laptops
running in the "N" mode to get decent response. I've used this setup with Timbuktu remote
control software and all works easily.

Stuart Heggie <stuart.j.heggie@...>
 

Thanks! I have a 4 port USB hub on the mount now and everything goes into that and one single USB to the laptop. The appeal of wireless for me is that the laptop is not that powerful but is good for running the imaging session. The house computer is powerful but inconvenient for running the session. Further, I have to cross my driveway and in winter, heavy snowfalls make it a hassle to run wires to the observatory. Still, I think your suggestion is probably best. I will keep it in mind if trouble starts with my wireless setup. Thanks again!

Lunar or Siderial Tracking for Saturday's Moon-Venus Conjunction

drgert1
 

Hello All,

On Saturday the cirrus clouds prevented deepsky CCD imaging in the Bay
Area. However I wanted to make use of the occasion and so I ended up
taking pictures with the Canon DSLR of the nice conjunction of the
Moon and Venus in the evening sky.

For the photos I used a Tak 4" F8 APO and AP0.67x focal reducer. This
put the conjunction nicely into the frame of the Canon RebelXT DSLR.

Interesting to note that I tried both siderial and lunar tracking for
the longer exposure shots of the sequence. The long one at the end of
the sequence is 15sec. After comparison I decided that it's more
annoying to have dozens of tiny trailed stars that an ever so slightly
smeared moon. So I ended up using the siderial tracking shot for the
sequence on the web page.

I had a lucky shot witht he airplane crossing the moon, too.

Enjoy,

Joe, could be a coincidence. I went to the AV store where I bought it, described everything I'd done to get it to work and then the chap stared into space for a second then launched into this line of questions about the windows and how new they were etc. I went back, tried moving it down about 2 feet and voila. So, hardly scientific but certainly pretty darn suspicious.

However, I have fussed with computers long enough to know that nothing is as simple as we want. Other than it deleting my address book and all my favourites today, Vista has been surprisingly stable vs. XP at the same time in its introduction.

Hi Stuart,

Thanks for the explanation about the Linksys and windows.

I too found this problem odd - and was very curious why my cheap (G class)
Giagafast wireless router (set up as a repeater), was weaker looking directly
out of the walkout glass doors, than when I moved it above a bookshelf in the
next room (2 feet away). There, it's signal had to go through 2 inches of
Styrofoam insulation and a brick wall (and even an 8 inch cube of solid
Plexiglas that it was sitting in front of!

However, my 1985 sliding door has the old style thermopane glass, not the
inner optical metallic coated "E-Glass" filter, so I still wonder if your
theory holds. Maybe it's just that the two panes of glass, at a specific
spacing, cause the signal of a certain wavelength to get reflected by a
greater amount than going through brick walls.

Hi Stuart,

Just need to add one warning. To get the Draft-N router range and power
improvement, the old laptop need a matching Draft-N NIC card. In order for
an
old laptop to use the new Draft-N host adapter, it also must be running
WIN-XP, since these new cards aren't supported by Win-98/ME etc. If you
don't
use XP or the Draft-N matching pair, you get the standard wireless G range
performance. Depending on where in the house the wireless router is

you might need a repeater, to get any decent range.

I bought one of the new Linksys Draft-N routers but had just a cheap
Wireless G type laptop host adapter. With the router at the front of the
house, my laptop lost signal as soon as I went out the back door to the
yard.
I then set up a cheap "GIGAFAST or BLANC" wireless router which I got
during
their $3 Boxing Day sale, and downloaded the new firmware which now allows
it
to be used as a Repeater/Router. I parked it on a bookshelf in the back
room,
and now I get about 70% signal strength all the way to the back fence about
100 feet beyond the house. The signal repeats just fine from the Linksys
wireless Draft-N version at the front, through several walls and doorways,
and
the e house brick wall, to my observing site.

Also, Mizzou, if you decide on staying with serial cable, the official
range was about 50 feet. Any farther you need to use "shielded twisted
pair"
cable to get 100 feet or a bit more. After that, you would need an old
style
modem repeater for the cable. The other way, if staying with cable, is to
do
the RS-232 to USB, then with shielded cables again, use a USB signal
booster
device.
I suggest you go with a wireless router, and possibly a repeater, if

Dimensions of 600E dec head

Jeff Young <jey@...>
 

I'm in the process of buying a Mewlon 250 to go on my 600E, but the
mount is in Colorado (and I'm in Ireland). I'm having the Mewlon
mounting plate sent to me here (the scope itself will go straight to
Colorado), but I need the outer diameter of the dec head, and a brief
description of the mouting holes (I have an extra saddle here so I can
accurately measure the holes -- I'm just not sure which holes in the
saddle line up with holes in the 600's dec head).

Thanks,
-- Jeff.

Hi Stuart,

Just need to add one warning. To get the Draft-N router range and power
improvement, the old laptop need a matching Draft-N NIC card. In order for an
old laptop to use the new Draft-N host adapter, it also must be running
WIN-XP, since these new cards aren't supported by Win-98/ME etc. If you don't
use XP or the Draft-N matching pair, you get the standard wireless G range
performance. Depending on where in the house the wireless router is situated
you might need a repeater, to get any decent range.

I bought one of the new Linksys Draft-N routers but had just a cheap
Wireless G type laptop host adapter. With the router at the front of the
house, my laptop lost signal as soon as I went out the back door to the yard.
I then set up a cheap "GIGAFAST or BLANC" wireless router which I got during
their $3 Boxing Day sale, and downloaded the new firmware which now allows it
to be used as a Repeater/Router. I parked it on a bookshelf in the back room,
and now I get about 70% signal strength all the way to the back fence about
100 feet beyond the house. The signal repeats just fine from the Linksys
wireless Draft-N version at the front, through several walls and doorways, and
the e house brick wall, to my observing site.

Also, Mizzou, if you decide on staying with serial cable, the official
range was about 50 feet. Any farther you need to use "shielded twisted pair"
cable to get 100 feet or a bit more. After that, you would need an old style
modem repeater for the cable. The other way, if staying with cable, is to do
the RS-232 to USB, then with shielded cables again, use a USB signal booster
device.
I suggest you go with a wireless router, and possibly a repeater, if
necessary. The Draft-N "matched pair" version might eliminate the need for the
repeater, if you are running WIN-XP or (unfortunately) VISTA.

Hello to All,
I'm new to the ap 900 mount and astronomy. Mount works fine, but I
now want to utilized the remote control software of my laptop. The
laptop will be approximately 100ft away from the ap 900 gto, and I
realize that I will have to do a rs232 to USB conversion. Is there a
list of components and their manufacturers which will allow me to
control the mount from that distance?
I am not sure how all of the components will go together to make
this work. I currently have windows xp ver. 2, but no rs 232 port on
the laptop. Starry Night pro ver. 6 and pulseguide software
Any help and direction will be appreciated.... Thank
You,....Mizzou

Mizzou - I'm no computer genius but this might be an alternative to messing with cables etc. I have an inexpensive laptop in the observatory, also about 100' away, and a wireless card in it which talks to the wireless router in my house attached to my desktop. It is "wireless N" and reaches the observatory fine. With Pulseguide you could run the mount from inside your house and not run wires.
