I’ve had power supplies fail.  I’ve also had cables and connectors fail.

 

It’s worth checking.

I have everything running from the same power unit, this since the day 1 two years ago. Nothing has changed and everything else still works fine. I’m not planning to have a separate power for the mount alone.

Have you measured the voltage that is getting to the mount?

Well, it does no harm by checking whether it is a power supply problem. They have been known to fail. First thing is to put a multimeter on it and make sure it's spitting out the correct voltage. The second thing is to just power up the mount *without* any of your accessories/gear to see whether you have the yellow light. If you don't, then you know it is the power supply.

Try one or more CP4 power cycles and "Resume from Park X"

Re: Mach1 and GTOCP4 Yellow Light

There is also some mysterious limits function in the CP4 that I have encountered in the past that I don't yet fully understand when using the CP4 and just the hand controller. It might manifest in other control scenarios as well. Basically, one day my Mach1 with CP4 wouldn't slew very far to the East (or West. I forget.) before the power light would go yellow and not let me slew farther. This was on a solid 13.6V 10A power supply. No hanging cables or other mechanical snags or problems. Cycling CP4 power got the red light back but as soon as I would try to slew into the "forbidden zone" the light would go yellow again. The mount was finding things in the sky everywhere else just fine and time/date/location/TZ info in the hand controller all looked fine. I tried a couple of "resume from Park X" procedures and suddenly the problem vanished and I could not duplicate it. I suspect that some safety limit variable was out of sync in the CP4, but I was unable to reproduce the problem to study it.

It has resurfaced about every other month or so on my Mach1/CP4 and the solution seems to be to do one or more CP4 power cycles and "Resume from Park X" procedures to get whatever variables inside the CP4 that are managing safety slews resynchronized with the rest of the CP4 code.

I shared this info with the AP CP4 programmer but I didn't hear back if he was able to reproduce the problem and/or get it figured out and fixed.

And of course there is always the chance that somehow I was unknowingly causing the problem and there isn't a mystery horizon limit bug in the current CP4 code.  

I hope this helps.

This started a week ago when I would suddenly get a Yellow warning light with a random slew when connecting the mount with the SGP. My first thought was that the control unit has condensated again but I was wrong and it turned out to be bone dry. Next I tried to fiddle the power and the Y cable and that helped and the next few days were fine. Last night the mount had violently slewed again so my I’m thinking now that I have a faulty cable.

I ordered both new cables but I am wondering now is there anything else I should check before changing those cables tomorrow before a clear night again?

Re: Waves breaking on Orion's shores

Hi All,

Question arose about the image being wide field, and whether it was using the 130GTX. I had to go back to the original Fits files and found that the camera was not STL11K, rather it was the FLI 16803 with the 130GTX and Quad TCC in a custom modified rear assembly.

The scope was modified by Dennis DiCicco, we had worked together to determine the exact back focus needed to cover this big chip. The focuser was removed and replaced by an FLI focuser directly to the back of the scope. The image was a test image taken by Dennis to calibrate the distance for a flat field.
Dennis built two scopes which were to be used to produce mosaics of the Milky Way.

Yep, I think that answers my question. Now (like I said earlier) need to wait for the rain to stop and the clouds to clear (or, at least the rain to stop!)
Thanks Ray.

I just created a complete meridian exclusion zone for my location in
APCC and for the first time I tried to start an imaging session in the
east (CW up) to eliminate the need for a meridian flip. I'm obviously
doing something wrong because I can't slew to the object without the mount insisting on going pier east. I use Stellarium as my software for selecting objects and SGP as my main controlling suite. My mount is the AP1100GTO.

Can anyone point me to a process workflow of how to start a session as I would like?

I’m pretty sure I did that but I’ll need to check again once it stops raining! I had the delays set but when I tell Stellarium to skew to the object it flips the OTA into the normal orientation for eastern objects.

Hi Mikey,
I don't use either APCC or Stellarium to control my AP1200, but I achieve what you are trying to do by setting a meridian delay in the V2 driver, so have you tried that? I'm not on my observatory laptop right now so can't recall whether you need to set a positive (+) or negative (-) meridian delay to start with the CW up pointing east, but you have a 50:50 chance so it's quick and easy to check.
Good luck,
