Re: APPM - unable to reset measurement points. #APCC

Thank you Ray!

I don't have "Pause after each slew" enabled. The strange thing is that, after the first zenith point is done,  APCC says that the mount is slewing but it's not actually moving. I am going to try again tonight.

Tom,

APCC does not take images. APPM takes images, but only for creating a pointing model, during which time PHD2 should never be
running.

Subject: [ap-gto] APCC with Dual chip SBIG (legacy) ST10 camera

Hi everyone,

Does anyone know if APCC can drive both the guide chip and the main chip
of an SBIG ST10 dual chip camera?
Seems difficult to share one serial-USB link.
For example with NINA I can connect the ST10 main camera, but then a
guiding program like PHD2 cannot connect to the guide chip, neither can
NINA.
The PHD2 manual mentiones something around dual-chip SBIG camera's by
installing an SGP API guider ASCOM driver, but that doesn't work either.

Maybe it's possible to try with the oldfashioned ST4 cable from the
Camera body to the AP1200GTO mount guider port, even if you already have
a serial link?
(but that feels more complex than required with 2 cables)

Maybe APCC can handle this

Any ideas or suggestions?

Best Regards,
Tom.

Hi Andy,

No matter how I change my points, I have two points that are stuck at the zenith.
Those points near the zenith are reference points automatically created by APPM. There is one on each side of the meridian.

it solves and then it gets stuck there.
Make sure you do not have "Pause after each slew" enabled on APPM's Run tab.

APPM - unable to reset measurement points. #APCC

Edited

I am running APCC pro V 1.9.4.3 and the other day something strange happened. 
No matter how I change my points, I have two points that are stuck at the zenith. APPM starts and goes to the first point at the zenith, it solves and then it gets stuck there.
I tried resetting the points many times, I also tried deleting the settings file but those points don't disappear. I have attached a screenshot of a point map and circled the two stray points in red. Is there something that I am doing wrong? This started a couple of nights ago and now I am not able to create a model.


Edit: I realized that those points are always there. However the issue still remains that I can't get past the first zenith point.


Re: [ap-ug] AP 900 Dec frozen

Definitely the problem is with the cable. Originally, I was able to use the keypad to move the scope east west, but I could not get the keypad to move the mount north south. So, once it cooled off this afternoon I switched the cables and the scope would now move north south but not east west! Have ordered a new cable from Astro and physics. Thanks Roland!!

I have had trouble with that cable for the Dec axis in the past. Apparently, the person I purchased the mount from was using a cable that was far too short And I had trouble placing the CP3 computer close enough to the Dec access to be able to use it properly. The Dec cable is too short. So, I went to Astro-physics.com and ordered a Y cable for the 900 mount. Thanks!!

I've just barely gotten the mount setup in the daytime and have not done a PA yet.   

That exactly accounts for why I was pointing below the horizon in Park5.

In that case you have told the CP5 the wrong location information.

To test this, send the mount to Park3, then Park2. If these are correct, and Park1 and 5 are wrong, you have the wrong location in the keypad or whatever program you are using to initialize the mount.

You see, Park3 is a known reference which does not care about location. That's why you should always start there in any troubleshooting scenario. Same with Park2. They will always be correct and you should always start with these axes set to their proper place.

Park 1 , 4 and 5 all use Location data to point to the northern and southern horizon. So if they are off, your location settings are wrong. Logical, yes?

i received my 400GTO and this thing sure is a beauty.  What a wonderful little mount!  I'd MUCH rather have this than any of the new harmonic designs. 

My stowaway is out of commission as I need a PP adapter and I've sold my 900GTO in anticipation for the Mach2 delivery so that leaves me with just the 130GTX right now.   I added a CP3 to the mount, updated the CP personality and have successfully connected to APCCPro. 

I put the 130 on it today and did some testing.  The mount slings the 130 around like it weighs nothing. 

I still need to run a PE curve with Pempro and build a model with APCC.  It will be interesting to see how this little mount performs!

One thing that I find a little strange is that DEC seems to be off a little bit.  Example:  If I'm in park position 5, with DEC pointing at altitude zero, and then repark the mount into park 3, DEC is not pointing at the pole.  It's off by a fair bit.  I've checked the time settings, and all looks good.  I'm wondering if there is a setting somewhere that could be causing this, or if there is something a little off between the CP and the mount.    When I do the test above, APCC shows that DEC is pointing directly at the pole, as does the driver.

ASTAP clearly indicates the problem above. The image scale is set incorrectly. APPM requires that you set the image scale correctly
within the percent tolerance you specify.

Bill, bad plate solves happen. In fact they happen a lot with ASTAP and longer focal lengths, so APPM cannot assume that the image
scale reported by ASTAP is correct. And there are cases where the plate solves fail.

Why don't you set the image scale set correctly? That's a requirement for most plate solvers.

Re: RAPAS on AP900 with CP4

Dean Jacobsen
 

Aha, I didn't realize that the CP4 has to be rotated 90 degrees vs. the CP3 box.  My 900 had the CP3 box and there was plenty of clearance. 

The 900 RAPAS adapter does push the RAPAS further back from the rear of the mount though.

What is the length of the overhang?  How far does the CP4 extend past the polar axis rear cap?

Hi, Chris—

 

Do you mean you have just the Meade OTA, and that’s why you need to find a tripod? I can’t imagine they’re very plentiful on the used market, unfortunately.

 

If you get lucky, you’ll be glad to know that the bolt holes in the A-P Flat Surface Adapter nicely avoid the cast structural webs on the underside of the tripod head when the FSA is centered and the N is aligned with one of the legs.

 

Good hunting!

Tomorrow the GTOCP4 and 155EDF go on it and I’ll start to RTFM and exercise the mount. When I think I understand its operation well enough, we’ll disassemble it and reassemble it in the back yard with the legs extended. I’ll probably do some imaging with the 155 first, but then swap it out for why I bought the 1600 instead of the 1100 – the Meade 16” SCT. For that, I definitely WILL need my son!

  Hi Dean,

thanks for your message. Did you use a CP3 or a CP4 controller with your AP900?  Unlike the CP3 the CP4 has to be rotated by 90 degrees to fit between the forks so protrudes at the rear.

best regards,

Dan

Hi Dan, check out the RAPAS page on the AP site.

https://www.astro-physics.com/rapas

There is a picture of one mounted on a 900.

I used one on my 900 with the controller mounted on the RA axis as shown in the photo without any problem.

Don’t forget to also pick up the 900 specific adapter.
