Re: APPM plate solve anomaly

Ray Gralak
 

Gary,

I think there is a bug in ASCOM 6.5 beta. That would explain why going back to 1.8.2.1 didn't help. Luckily your data is not corrupted by this.

What's happening is that the ASCOM precession object looks like it can be initialized exactly once. For efficiency's sake APCC reuses the same object so all of the plate solves in your screen shot have the same RA/Dec and thus some huge offsets. The behavior is probably not expected but I haven't had a chance to look into this.

Hi Ray,

Thanks for the reply. I recently installed 6.5, so that is probably the cause. I'll install 6.4 SP1 and will let you
know if that solves the problem.

Re: APCC 1.8.3.1: strange behaviour when parking at Park1 position

Ray Gralak
 
Edited

Yves,

APCC can force the mount into a counterweight-up position first which, depending on the start position, might make it seem like it's going the wrong way.

If you don't think that's the case, then find in your APCC log where the park started. The meridian delay should be set to "0" before the park is issued by APCC, except if there is a multipart slew. Search for "meridian" to find places where it can get set.

Hi Ray,

This morning at the end of my imaging session I parked the mount at Park1 position as usual but the mount
was slewing at the opposite direction (Park4 or Park5). I stopped the slew and re-initiate the Park1 process
and the mount went back to the Park1 position as it should. By chance my system is not completely
automated else it can be a serious problem. At that time, the ASCOM driver was disconnected.

I will sent you the logs on request.

Hi Gary,

Have you updated the ASCOM platform lately? The version you should be using is 6.4 SP1. Do not use the 6.5 beta.

Subject: [ap-gto] APPM plate solve anomaly

Hi Ray,

I've successfully used APPM to create models in the past for my 16" F/8 on a 1600 mount. Recently, I went to
create a new model and thought I'd first upgrade to 1.8.3.1 from 1.8.2.1. After the upgrade, I started to do an
APPM run with the Small Map Default type. I am using Pinpoint Full (v6.0b) and the USNO UCAC3 catalog.

Unlike past runs, this time I started seeing significant RA/Dec deltas as APPM performed plate solves at the
different measurement points. I've attached a screen shot of a typical run. You can see the first image taken
at zenith has small RA and Dec deltas but after that, they were huge. In fact, you can see the same RA and
Dec values in the RA/Dec Solved columns.

It seems whatever the RA/Dec coords of the first plate solve are what subsequent solves are using as their
reference. I also have included two screen shot images of the results of running the Plate Solve function. The
first shows very small RA/Dec deltas but the second one, taken after moving the scope a few degrees, shows
significant deltas. It seems the "Topo" values haven't changed and are what are being used to determine the
deltas. How are those Topo values being determined?

I've also included a screen shot of the Plate Solve Settings. I've tried running with both the checkboxes
checked an unchecked but they didn't affect the results.

I've tried re-installing the previous version of APPC Pro and Pinpoint but the problem persists. I don't see this
problem when running PinPoint via MaximDl or using Visual PinPoint.

I'd appreciate your help in figuring this out!

Gary Steffens

I got mine off - waiting grease. It shipped the day I called in the order but UPS didn't make it yesterday. (par for them). It's on the truck for delivery today so I may be able to re-grease tomorrow.

Re: help with AP900 guiding via ASIAir Pro

Dean Jacobsen
 

Steve,

Ray said that your driver logs report an "E" chip in your CP2 controller.

You said that the seller told you that he had upgraded the chip to a CP4 chip but Roland said that there was no such thing as a CP4 chip for your controller.

It might be worth your time to open up the controller box and see what is actually in there.  If I recall correctly the chip version is printed on the surface.

Re: help with AP900 guiding via ASIAir Pro

sgbonnell@...
 

p.s. your description of the problem seems to match last night's observations on mount behaviour..

I had previously thought that somehow the tracking was being disabled on the mount when guiding was initiated, but I think it is more likely that the mount is executing an open looped move per your explanation above.
When I deliberately turn off tracking, the stars trail in the OPPOSITE direction to what I had been seeing previously when trying to guide. 
So it is not that tracking is disabled, rather being overridden by open Move command.. 
Steve


Re: help with AP900 guiding via ASIAir Pro

Hi Ray,
I think I originally had CP2 specified in the mount set up and had changed it to CP4 trying to debug the problem...
But to be sure, I'll reset the driver to CP2 & AP900 and give it a try tonight..
thanks for taking a look at the logs...
cheers,
Steve

Re: help with AP900 guiding via ASIAir Pro

Ray Gralak
 

Hi Steve,

I see the problem. The old firmware that you have (Rev 'E' chip) requires separate start and stop commands to issue guider moves, but the driver is sending timed moves. Timed moves handle starting (and stopping a guider move after the supplied duration value) from within the control box.

However, I think the old firmware in your mount is handling this as a simple start move and the move continues while waiting for a stop command. Since the driver expects the control box to stop the move after the supplied duration, the driver does not send a stop move command. Thus, the GTOCP2 firmware keeps the guider move going until you stopped it with an appropriate key press on the keypad.

I think you should be able to fix this problem by selecting the correct mount type and controller in the AP V2 driver setup. That is, make sure you have AP900 as the mount type and GTOCP2 as the controller. In one of your logs you have GTOCP4 selected as the controller and no mount type. This will cause the driver to potentially send commands that the GTOCP2 will not understand, like the timed moves.
