With the chance of clear skies tonight, I thought I might experiment a

little with using an ST-4 with my 900GTO mount. Since I am sure there are

people on this list who have plenty of experience with this, I thought I

might ask for a little advice on settings to help me jump start it and have

a productive evening.



The setup would be using an 80mm guidescope with a focal length of

970mm. I will initially use a computer for focusing, but from there am not

sure about using one for the actual guiding. If I decide to go with the

stand alone route, what settings have you found to be useful?



Thanks,



Bill Gardner

I've been out of the "sport" for the last mumble> years, but since

Saint Luke called wrt my 900GTO, I've been going through my gear boxes

and rediscovering what I have. I can't be the first to do this...:)



Anyway, I run across my ST-4 (purchased in 91 or 92). Amazingly, all

the cables (sans one) are with it. But no software. I've got this file

cab drawer full of floppies that are sure to have some historic value.

Hell, I even found a AOL 1.1 floppy in there. But no SBIG floppy. As I

recall, that software was DOS based, which would eliminate win2k as

the host unless I fool around with some sort of hardware access hack

(not going to do).



1) Do I even need an ST-4 these days? I bought for guiding, but do I

need it with this 900GTO?



2) If the ST-4 is not redundant, what 3'rd party software do you guys

use with an ST-4 (on win2k or xp)?



3) What is the pinout on the 900GTO mount for the ccd interface (I

can't find it in manual)? This is the cable I can't find, so it's time

to make one (if I need one)...

Whether or not you need an ST4 is dependent upon what you intend to do

for imaging. Most of the CCD camera's have built in guiding chips,

therefore the ST4 would be redundant. If you plan to use film, then, yes

you will need to use the ST4.



The ST4 doesn't require a computer for guiding, but you can use one. I'm

not sure about win2000, I managed to bypass that version. Free downloads

are available for the ST4 at the SBIG site. I don't believe there are

any Windows based applications that can control the ST4, but I'm not

positive.

Hi Chris:

Congratulations on your new 900 GTO. You don't need to run your ST-4 with

computer software; I run mine stand-alone rather than confuse myself with

yet another computer program. If you want to use the computer, you can

download the software from the SBIG site, free. To run it with Win 2000,

just run it in a command window. (Start/Run, type cmd in the window). The

ST-4 is a great guider and I use it all the time with my 900 and 1200 GTOs.
