simple meridian management for field imaging automation withh CCD Autopilot with MAch 2 #APCC #Mach2GTO

Andrea Lucchetti
 

Hello Ray & Group,
I have a Mach2 and want to use it with CCD autopilot for session automation.
It is going to be used in the field, no fixed set up.

I'd like to know what is the simplest meridian set up to be used with APCC Pro, CCDAP and the Mach2.
I don't need any complex management, only:
-to allow for 45 min tracking in the west before meridian flip, about 45 min east tracking (less important) 
-ability to slew and point in the above area
-prevent slewing near the meridian

After having read many, many times the manual, I am still confused (my fault)
I wonder if setting only the AE limits it is enough for me (or may be too much). in this case it would be nice to know how to set the "Meridian panel":
I assume I don't need to set "meridian delay"
I assume I don't have to touch the "meridian tracking limits/hour angle panel"
I assume I don't need to flag "enable Meridian Tracking limits" in "Operation" panel, because in the help I read: "DO NOT use any other method for setting a meridian delay while you are using the meridian limits.  When properly configured, the APCC meridian tracking limit logic will maintain the correct meridian delay in the system."
Also, because CCDAP manages the meridian flip.
 
So, what to do if I use the simple AE limit in the meridian panel?
As CCDAP manage the meridian flip I need to know a procedure that work with this software.

I can certainly get help from John on more established AP mount, but the MAch 2 is new.

Thank you very much in advance,
Andrea

what do green and blue mean?
It means they are healthy.

If you want to see before and after, simply turn on your favorite guider program. Pick a star near the celestial equator and meridian. Start tracking but turn off all guiding pulses. Watch the RA and Dec axes. You will see the RA axis track steadily without any periodic error. Both RA and Dec will jump around a bit due to atmospheric seeing, and that is normal, and is not something an encoder can correct. Both axes will probably drift from their zero line, and again this is not something that the encoders can correct. That drifting will be almost 100% due to your polar alignment.

Once you do these tests, you could turn the encoders off and watch the RA for it's normal periodic error (Dec will have none, of course). Be sure to turn them back on after this run.

Now that you have satisfied your curiosity about the encoders actually doing something (elimination of PE in RA), then it's time to apply the models in APCC-APPM. This is where the real work of tracking occurs.

On RA the LED is green, and on the DEC it is blue, so the fact they are not red is good, but what do green and blue mean?

I have the AE tab on APCC-pro and the encoders are enabled.  I would like to ascertain that the encoders are making the mount track better or was I seeing better tracking just because of the pointing model?  

Thanks for all the feedback.

Yes, the LED colors are meaningful.  When I upgraded my mount to absolute encoders, I found the Renishaw documentation for the read heads and it described the meaning of the colors.  Essentially, red is no signal, orange is weak signal, green is good signal and blue is the strongest signal.

 

The first time that I powered on the mount after the upgrade, I saw lots of orange, and a bit of red.  I called AP and spoke with George.  He relayed the steps that they use to adjust the encoders.  It was quite simple and took me about 10 minutes to adjust them so that both axes were green and blue all the way around.

Bill,

I don't think the LEDs at the read heads are meaningful. It simply tells you the encoders are powered on but not necessarily enabled. You can power up the mount and the LEDs will still light up whether the encoders are enabled or not. That's at least what I remembered when I first installed AE in my A-P1100GTO mount. It was very easy to install.

I think it's best to use either ASCOM driver or APCC to tell you whether the encoders are enabled or not. Or while the mount is tracking, you can forcefully move either axes with your hands and if either axes fight back to move back to original position, then you know the encoders are working.

Hi Bruce,

Thanks for the endorsement of PoleMaster and SharpCap. I purchased the Pro edition of SharpCap yesterday and I have a dovetail holder I purchased from Opt for the PoleMaster. I'm looking forward to trying out the new system once I get my scope. Hopefully within a week or two.

Best,

Hi Terri,

Thanks for the info. I need to get some furniture dollies to move my equipment with and mark the position as you did to speed up polar alignment.

You will need to have software version P02-06 or later software loaded in the CP4. You can do this using the Command Interface via Ethernet connection or WiFi. The above commands can be sent to the mount via the Interface Terminal. We plan to publish other new commands as they become available and have been fully debugged.

Re: 1100GTO upgraded with AE...

 

Encoder LED color indicates if the encoder is powered, but also the data quality it is sending. If your encoder LED is red, it means you will not be getting any useful data from the encoder. Blue and green are good colors to see.

The color matters based on the sheets from Renishaw. The other point I mentioned, the AE tab in APCC Pro also matters since you won't see that if the personality isn't set correctly.

Re: APPM Questions : APPM / GTO1100AE Blocking Issue

Roland Christen
 

What is your power supply?
What is your outside temperature?
You may have too low voltage from your supply, especially now that it is getting cold outside. For cold temperatures it is recommended to use 16 to 18 volts to run the mount.
You might get by with 12 volts if you turn the maximum slew speed to 600x.

Also, sometimes it seems that the dome is still slewing when the camera starts to take an image - so how is that
overcome? Sucks to be taking a picture of the inside of the dome.

Hi everyone,

I wanted to share our latest results from using the our AP1600 with absolute encoders, doing unguided with APCC/APPM model

This is from last night's run, we used 900second (15 minute) unguided exposures of NGC 1097 on CDK17, image scale 0.63"


You can download the fits file here
(image was calibrated and background gradient lightly processed, but otherwise unchanged)  



Overall I'm pretty happy with these results. We were admonished to use guiding from the start, but we had faith in the AP hardware and the APCC software. 

We rely on APCC and the APPM model builder. The model was approximately 180 points on each side, limiting it to 35 degrees altitude. 

Ray has done some great software improvements based on our results over the past year. We are at a very demanding focal length for unguided @ 2930mm. He has been very responsive and helpful, as have all AP staff we have worked with, including Roland. 

We still have work to do in other parts, and we would like our keeper rate to be higher, but progress, not perfection right?
