Subject:	Controlling ETX70

Hallo Wolfgang,

I have read somewhere on the ETX site from Mike Weasner you have
problems controlling ETX70AT from your software. I use Starry Night Pro
Plus version 6 and this works perfectly with my ETX70 also with the
ETX105 PE. In the setup you have to set in the telescope window, the
software to[ LX200 and Autostar]. I use also the cable 506 so the cable
can not be problem if it is not defect of course, by the way the litle
box in the 506 cable converts AUX signals to RS232 signals.

I have also the with ETX105 delivered Autostar suite this works with the
ETX105 but I did not try this program together with the ETX70. I prefer
anyway Starry Night is easier to work, with other programs I do not have
any experience.

I hope you can solve your problem
Auf wieder hren


From:	Harder, Wolfgang (
thank you for the message. But the Problem is not the controlling from
the first Screen.I have the Com 1 under control.The slew motion is
correct. But in the Window  under the telescope / Handbox is the
Problem. The Function Initializing is corrupt. I have no men, no Goto,
no speech, only the N/S/O/W buttons are working. Meades  answer: use the
"Autostar 497" that is correct. But i have a 494.with cable 506. The
Problem exist also with Astrostar-Suite and Astronomers edition.
Mit freundlichen Gren

Subject:	ETX125 to Kstars connection assistance

I've been reading many posts about the telescope control capabilities
from kstars, however, being relatively new to this I have some questions
on which I would like help/advice.

I have an ETX-125 and a Fedora Core5-based laptop with kstars, the
autostar handbox I presume is working but the LCD? screen is gone so
though the telescope responds to some commands I can't see what is
doing, so is like not having the handbox controller at all. Q: To
connect my laptop to the ETX do I need to go through the autostar
handbox? (i.e. laptop->hbx:hbx->scope) or can I just go from the laptop
to the scope? what type of cables do I need? my laptop lacks the serial
RS232 port but has USB's.

Any comment much appreciated and sorry if this has been addressed

Mike here: Yes, you need to use the AutoStar. The software tells the AutoStar what to do and the AutoStar controls the telescope. You will need a #505 serial cable (you can easily make one; see the cable section on the Helpful Information: AutoStar Info page). You will also need a USB-serial adapter; see the article "AutoStar and USB" on the AutoStar Info page.

Maybe you can help me,is there any programs dedicated to observing the
Sun,like in tracking it for solar photographs and observing it long
periods on my pc. THANKS  Steven
Mike here: See the article "Setting a Solar Tracking Rate" on the Helpful Information: AutoStar Info page. I'm not familiar with any applications specifically designed for solar imaging. Usually, once you had a proper safe solar filter, just imaging as normal should be OK.
