Problem with V095A

chuck_e1234
 

I just upgraded to V095A on my telescope which uses a Servo1 under Win10.  Every time I try to access the Run Script tab SiTech.exe crashes.  There is no error message.  It just goes away.

Win10 is current. ASCOM is 6.4sp1.

Any ideas?

Thank you very much

I couldn't find out if it's possible or if they have a TCP/IP interface, or DLL.  THey do have an extensive scripting language, but it looks like it's run from within Prism,
I sent them an email to find out, I'll let you know when I get more information.

Hello,
    In Europe there are many users that use Prism version 10 telescope control software. In the last update of sitech.exe I’ve seen added support for SGP for photoinit/camera control. Would it be posible in next updates to add Prism as well? 

With Prism I can do everything(image aquisition, focusing, platesolving, processing,spectroscopy,photometry...etc), without any need for external software.
But... I had to buy Maxim dl for the photoinit and running the script for pointxp. (Nebulosity didn’t work for me)

Best regards,

Re: Positive Encoder Feedback & Focuser II

Hi Russell,

I'm not sure of the case that Dan was referring to, but  I know of a case in San Diego where a large and old mount was converted to SiTech with Brushless controller and absolute mount encoders.  The Dec drive on that mount had two sources of positive feedback:  1. the main gear on DEC is a 22 inch diameter spoked brass gear with the rotating worm tried to climb, bending the gear allowing the worm to actually climb the gear teeth, causing positive feedback easily detected by the extremely accurate absolute encoder.  2. The bearing block holding the Dec worm drive had some "Play" or could easily be deformed allowing the worm to climb the gear teeth pocket.  We stiffened up that worm bearing block assembly and think we have eliminated the positive feedback - at least it is now much less of a problem.  The manifestation of the positive feedback was that the Dec drive oscillated many arc-seconds in sustained oscillation sometimes.

Dan may have other examples of positive feedback since he has installed a number of mount drives for many very large scopes.

Positive Encoder Feedback & Focuser II

Russell R
 

Dan,

Watching your video about "increasing the accuracy of your telescope using software and hardware" ,at the section of positive feedback on encoders (about where the door bell rings) you said that it was the "friction of the worm on the worm gear and it was using the worm gear has a lever" to cause positive feedback on the scope in the video.  I understand the positive feedback loop to oscillate electronically and since a worm and gear are in fact a turning lever, are you talking about stick slip friction between the worm and gear due to spring pressure or bearing slop by relocating the read head location 90° on the Dec of telescope?  You got me cross threaded on this, can you clarify?

Also, in SiTech Focuser II on the <MirrorCoverControl> tab...... was this something for one of your customers, or is it an operational part of Focuser II that can be implemented by anyone?

Thanks,
Russell R.

Thanks for your input Ross,

I'm going to try that, thought I had to choose one option for auto flip in the Sitech driver.

Unfortunately the weather doesn't want to cooperate at the moment...
I post here when I have tested.

command doesn't exist. All that happens in ACP or CCDAP is that a slew
command is issued by the imaging software. At that point the mount
driver checks to see if the required slew is east or west of the slew
limit and then either flips the mount or doesn't based on (as I
understand it) "Side of Pier". So, I'd recommend turning that setting
off and setting ACP to flip at the meridian. Then make sure that the
time is correct everywhere and you should see the flip work. If that
happens properly then you can experiment and see how to make it flip
early or late.

Hi Che,

Thanks for your reply.
I had ACP working perfectly with my old mount this way.

The flipping point is set right to the meridian in both ACP and Sitech.
But when I tell Sitech to be able to track past the meridan, it seems
to also shift the flip point, so it won't flip on a GoTo.
When I tell Sitech to track past the meridian, ACP also has to know
that it can image some time past the meridian.

It’s USB for config changes like firmware updates.  The comm port will probably change its number with the change to USB.

Hi Juan,

The Servo II has both USB and Serial connections to the PC.  You can only use one at a time.  Only one of those allows connection and changes from the ServoConfig program.  Unfortunately I don't remember which works, but I think it is USB.

Thanks Don.
I'll try through USB possibly tomorrow.

Unable to upgrade firmware from V8.6 to V9.7

Hi
When trying to load V9.7 via serial port I get the following error message.
" Timeout Acknowledge from Controller b0=0 " 
I then loose communications with the controller and with a USB controlled relay board that I use to power on/off different observatory devices.
Any suggestions?
 
Also.  I  can operate the telescope from my Win10  laptop using SiTech095A and ServoConfig without any apparent problem.
Am i losing  any major functionality If I don't upgrade to V9.7  ?

Thanks

Make sure you saved your PXP model as  Autoload.pxp in the same folder as your SiTech.cfg.

Re: meridian limits

Albert
 

Thanks a lot Don,

I think it has become a little bit clearer to me.

As far as I can deduce now, it  may not be possible to manage flips the way I want to.
For that to work, Sitech should be able to track past the meridian some 10-20 minutes, but when a GoTo is issued in that zone the mount should flip immediately.
But when I read it correctly, all I can do is shift the flipping point to the west.

Albert

Just thinking, do I need to reset the park position in order for this to autoload,  Park was set before doing a mount model.

Problem auto loading mount model file

Che
 

Hello all
It's been a while since I've had my Sitech controlled mount in service.  I've done a sucessful pxp run and created a mount model.  When I start Sitech and unpark the model does not load.  I can load it manually.  I've checked the box to autoload but no joy.  I don't know if I've forgot to set something else or if I need to name my mount model something specific or what.  I'm sure its operator error.  Any advice
Thanks
Che


Re: meridian limits

Che
 

I am not familiar with ACP but if I understand correctly, you are trying to set up a meridian flip in both ACP and Sitech.  I think only one should command the flip.  If I am misunderstanding, I appologize
