Something like this:

762K Switchcraft | Mouser

 

It has locking screw.

Xiaoyang,

 

Whenever you run cables through the mount, be sure to allow extra slack so that the mount can move around without binding.

Any advice on through-the-mount cabling on 1100?

 

Last Saturday, I was experimenting some changes to my setup and had one 12AWG wire through the mount from battery to a power splitter on top. And I was testing new guide cam but keeping old guide cam as backup in case it didn't work. So I had USB3 cable and USB2 cable through the mount.  I got some weirdness in guiding where DEC jumped. The guiding was able to bring the mount back but PHDLabs complains that the PA was way off. My PA scope is setup to be within less than 3arcmin and I also checked with PHD2's PA. My PA is certainly better than 3arcmin.  Later in the session, I also swap to old guide cam (SSAG) and it was the same.

 

Now I suspect that it was due to the heavy load of cabling through the mount (worse if not through the mount and dangling).

 

Is there any guideline as to how much cabling and what kind of cabling is OK through the mount?

I just thought that though-the-mount cabling gives very short arm to the weight of the cables that the extra unwanted torque should not exceed that of the unbalanced torque from the scope setup, since we can never really perfectly balance the scope and the focusing and this and that probably make the balancing even a bit worse.

A mere observation of your statements made ("illusory", "imaginary", "synthetic" ...etc) and the weak premise it carries.

Your subjective definition of reality fails to take into consideration additional factors such as the limitations of human biology relating to spectra. Technology has expanded our ability to see beyond the visible wavelength and present the object in an entirely new light (... pun).

Based on your definition of reality the IR based image of the Horsehead that exposed a trove of galaxies beyond the wall of dust is "illusory" because our eyes cannot perceive it naturally.

In my opinion, that's incredibly short sighted. (I apparently love puns).

I am both a visual observer and an imager. I always keep my 12.5 inch Dob next to my imaging rig. I also use my AP 155 for as much visual observing as imaging.  I find that imaging enhances my visual experience. When you study an object for many hours in preparation of an image you see parts of the object that you never could see visually. When you look at them visually you see more for having spent all that time looking at the detail of the object.

Why are some visual observers so bloody sensitive with hints of passive aggression?

As a visual observer and a photographer myself, the tone of the question was very much in jest, IMO.

I think you should start with making sure all of your ASCOM applications are NOT run "as administrator". In general it is best not to run applications as administrator but if any one of your ASCOM applications needs to run "as administrator" then all the rest will have to be run "as administrator".

Ray,
I have checked and double checked and none of my programs, in use or not in use are run as administrator.
Now, to be clear I am checking properties, compatibility.

One thing I would mention, and this may be inconsequential is that there is only a single user login on this hard drive

When I first got this computer from Dell it had an Admin login and I was prompted to set up a user login.

The first hard drive failed after a month and the replacement was set up with a single user login

There was no resident admin account.

In fact, I was out last night with my AP130EDT on the AP900GTO CP2 (which was how I rediscovered the option to turn ON tracking since mine was set to STOP on start-up). Was a gorgeous night up here in rural Ontario.

I am planning to recommission my AP155EDF on the AP900GTO and start imaging with a new-to-me STL11000. LRGB for now. Built a second observatory to hold it. 12' clamshell.

I’ve always wondered how this convention got its start - I have never wanted a mount to track on startup. I suppose it’s too late to make safety the default on this one - I know that many telescope control programs also start tracking at connection. It’s a tough battle to fight. :-(

The default action should always be a safe one, IMO.

Re: ASCOM driver incorrect LST problem

Andy Galasso
 

Hi Ray,

I have the mount setup to initialize from the PC and the hand controller is not plugged in.  Here are my settings: http://adgsoftware.com/misc/AP_V2_Driver_ASCOM_Setup.png

I believe I left out on important bit of information.  The slew was done by a script, something like this:

    scope.SlewToCoordinates(scope.SiderealTime + 2.5, 10.0)

When the ASCOM driver returned an incorrect value for SiderealTime, the scope did actually slew to the location it was asked to slew to. But since the SiderealTime reported by the ASCOM driver was wrong, that location was below the horizon.  This is consistent with the observation from the log that the mount itself was initialized correctly and working properly (and had the right sidereal time), but that the ASCOM driver was giving the wrong SiderealTime.

I think we can rule out the mount and focus on the question of why the ASCOM driver was giving the wrong SiderealTime.  Right?

Andy
