Thanks for that information Roland.

It is interesting that you used the same number of blue sub-frames as for the other filters. I have read that most CCD cameras are less sensitive to blue light, and with that many blue stars I would have expected to see more blue sub-frames.

I will add NGC 6791 to the list of objects to capture with my 180 EDT if we ever get a break in the weather and the Sahara dust in Southeast Texas.

The way it is set up isn't the best, but there is an "add more" button on the bottom so you can enter in the details for one filter first, then click on the "add more" button for the page to expand and you can add details for another filter, etc.

Roland, on the acquisition details page there is an orange button on the upper left to get to a different form that will let you enter more detailed acquisition information.
Yes, I use that, but it still does not allow different exposures on different filters.

Re: Mach1 and GTOCP4 Yellow Light

Roland Christen
 

If the yellow light comes on immediately, then you probably have a bad connection from the CP4 to one of the two motor gearboxes. It could be your Y cable, or it could be inside the gearbox. Most likely is the connection to the RA motor. Normally the RA motor starts tracking upon power up. You can see that if you look at the end of the motor shaft, at the spur gears. If the motor does not start rotating, then within a few seconds the CP4 will shut power off and turn on the yellow light, indicating a motor stall condition. So, your first order of business is to find out if this is what's happening.

Thanks for the comments and recommendations.
OK, what’s the easiest way to measure the voltage to the mount? I think I have a multimeter somewhere. I did end up buying another power source from Amazon yesterday just in case I need to replace the existing one. Also, it sounds like the Y-cable is not probably the culprit here.

As said, in my case the Yellow light comes on immediately when the mount is powered on. I have yet to have a case where if the sequence has started OK the mount would have malfunctioned.

Re: Ancient Stardust

There was no way to enter each filter exposure, only the total exposure. Each filter had 12 exposures of 300 seconds for a total of 48.

Very nice Roland ! The technical card did not say how many sub frames were taken through each filter. Can you share that information with us ?

I have the same issue on my Mach1 and 1100 GTO with encoders, and even talked to George about it once when it was happening.  We were able to get the mount working by issuing some commands to the mount via the terminal interface, but then the problem would happen again at some point.  I could never figure out a pattern.
The version of APCC I was using when this happened about 1.5 years ago didn't give any indication the light was on (I only knew because I noticed slews weren't working), and I don't know if the current version of APCC does, but it sure would be nice for APCC to pop up an error message when this happens.
The light would go on with slews via software (SGP in my case) or the hand controller.  I have a CP4 on both mounts.
When it happens, I can slew one direction but not the other.


Re: Mach1 and GTOCP4 Yellow Light

Dean Jacobsen
 

Mikko, if the probes of your multi-meter are small enough then you should be able to just unplug the power cable from the CP4 and measure the voltage at the connector.  Turn on you power supply and all of the other accessories that you said also you run from the power supply and measure the voltage at the CP4 connector.  Then turn off all of the accessories and measure the voltage at the CP4 connector again.

A question for Roland and Ray:  is it possible to have the AP ASCOM driver read and report the CP4 and CP5 input voltage?

Re: Mach1 and GTOCP4 Yellow Light

Sounds familiar. It was as if the horizon limit on one side was suddenly up near (or at) the meridian.

In my case all I have connected is the AP hand controller and no other computers or smart devices.

In my case it wasn't any apparent limit, like horizon limit.  It would usually occur near the meridian, and once it was fixed, it would slew into the no-slew zone without any problems.

Roland, if you are into imaging star clusters - and who wouldn't be if they had one of those nifty 160EDF telescopes - then put NGC 7789 on your list.  It is another one of those ancient open clusters with numerous red giants.  Approximately 1.6 billion years old.  It is more than twice as big and much brighter than NGC 6791.

I ran across this little jewel a few weeks ago while hunting up something to image with the Mach2 and 160EDF refractor, using unguided exposures. The open cluster NGC 6791 has a dozen or so bright (mostly red) stars in the foreground and thousands of fainter blue ones hiding behind. Taken thru murky skies during a summer heatwave that won't quit.
