Re: COM Errors w/APCC

Steve Reilly
 

Thanks Ray,

Biggest problem with remote imaging is not "seeing/touching" the systems. As
far as I know the cable to the mount (CP4) from the switch was replaced, the
switch itself (or at least requested) but nothing was said about the cable
from their switch to their network switch. I haven't seen any sign of the
computer cycling on/off as would be possible if the heat sync/fan was dirty
(over heated).

Guess I'll need to ask the SRO crew a few more questions.....

Steve,

Looking at your logs, it is probably a network issue but that may be
difficult to pin down. Since you replaced the switch and cable(s), it could
be the Ethernet port on the computer, the Ethernet driver, or a Windows
operation causing a delay in responses.
It could also be the computer has issues, especially if it was left out in a
potentially hazardous environment (e.g. cold weather, and smoke from fires
that approached SRO last year).

BTW, you said *the* CAT5e cable was replaced, but there should be at least
two cables: computer to switch, and switch to mount. Were both replaced?

I looked at APCC while running remotely at SRO this morning and saw 93
COM errors. While the system is imaging successfully these errors are
concerning. I have had many errors over the past few months and have
had the CAT5e cable replaced, power cycled the switch, replaced the
switch, and the behavior continues. I'm used to having COM errors when
it 1st starts and have delays in the startup script to try to minimize
the errors but these are going on throughout the night and aren't just
startup issues. At this point I'm not sure what needs to be done. I
use TCP LAN as the primary connection and COM3 as my backup. In the
time since starting this message and after clearing those errors I
already have an additional 7 COM errors. APCC just switched from TCP to COM
3 while looking at the log file for this morning. The log files can be found
here
<https://www.dropbox.com/s/uvj2ky00emjhncr/ApccZip-David_Weiner-2021-04-12-0

Any suggestions would be very welcomed.

Re: APPM model how many points portable?

Dale Ghent
 

Yes, there is currently no direct cooperation between NINA and APPM at this moment, but that can come in the future and I've worked with Ray to get a proof of concept of APPM->NINA working.

One APPM can utilize ASTAP directly as a solver instead of through a surrogate app, things will be much more straight-forward and lightweight. Currently, I do my APPM run during twilight with it utilizing the camera ASCOM driver (QHY in my case) and TSX as the plate solving provider. Once that's done, I shut all that down and then run my standard NINA stack for imaging through the night. While TSX is fine and functionally does the job of solving what APPM throws at it, it's still a bit slow and the ability to use ASTAP would let me uninstall the TSX monster from my imaging mini PC.

While I have TSX now I do not plan to use it with the AP1100.

I use SGP and ASTAP. A 90 point model takes about a half hour

I didn’t think astap was supported in the AP software; or is this coming ASTAP -> SGP -> AP?
I have also been thinking about using SGP and ASTAP.
Fwiw: I have been assuming APPM (?) uses SGP to capture and plate solve, and SGP in turn uses ASTAP to do the plate solve.
... but I'm far from knowledgeable on this, tho I would like to confirm this works or not without burning too many cycles ... But I'll probably just try it sometime soon.

Also fwiw I'm still on the SGP learning curve, along with a new camera. Was using maxim-dl, but I don't have full pinpoint. (And I've been avoiding TSX from a bad experience with it in the past, which is likely resolved.) I am almost 100% open at this point for image acquisition apps as long as they don't break the bank or my brain. e.g. Voyager has been noted in other forums, however it seems to me SGP is more intuitive, and maybe is more supported... and afaik APPM does not work with Voyager.

Point is: there seems to be many variations/options for software these days, which might have varying performance and capability levels. It would be good to know what works well (at this point in time).
I also am realizing "what works well" may depend on the imaging hardware one is using - whether ascom-only or natively supported.
E.g. I'm currently moving to an Ascom-only camera (at least I believe there isn't native QHY driver integration with with Maxim or SGP).
The upside is the new camera seems to have blazing download speed compared to the ST-8300M I was previously using.

Re: Mach2 thru-mount USB when using USB 3.0 ? (and an M51)

Jeffc
 

Thx everyone for the suggestions.   I've ordered a handful of super short USB-3 Male A -> Male A cables for testing.
I do feel the mount -> computer cable is a bit long.   It might be 10 feet (which is the shortest I had on hand).
(Fwiw, i'm also using USB for the Computer -> CP5 connection... on a separate port on the computer.)

I've resisted the Pegasus powerbox, but it might be time to upgrade the Dew Buster anyhow... sure would be convenient to have remote control for the dew heater.
Right now, I feel like the UltimatePB v2 is overkill, but it seems the Advance does not have a "managed" USB hub.  Plus, i could use the power (current) monitoring on a per port basis, especially when there are dew heaters involved.
The Eagle seems super clean, and flexible, but I'm just not ready to spend the $$ there.

If anyone knows of a good-bang-for-the-buck USB powered hub for the Computer -> Mount path let me know.  (Preferably fetchable from amazon.)   

E.g.  Dominique - what is the "HUB USB3" box in your schematic?   Is that basically the Active 16 meter cable?

Hi Jeffc,
I have a complex installation (see the diagram in PJ) and I have no problem with my QHY294C and QHY294M-Pro, even for the 47M mode flats of the QHY294M-pro. It is useful to put a Hub-USB3 powered at the output of the Mach2 before an active extension cable. I only have a bit rate problem with a QHY5III224c because with the Altair GPCAM3 224C at 154fps no problem either.
I think that the duration of the exposures should be limited to 180s with this type of camera and in particular without Ha filter.

Re: APPM model how many points portable?

Greg Vaughn
 

Hi Roger,

 

I started off with platesolve2 and SGP to support APPM and found it VERY SLOW.   When I switched to ASTAP as my plate solver in SGP, it sped things up tremendously.  Yes you can use ASTAP in SGP in conjunction with APPM.

 

I had some difficulties recently with APPM that turned out to have nothing to do with the software.   When I used APPM on a larger/longer refractor my 12V power cable on the back of the CMOS cooled camera was catching on something when it got to a certain geometry in the mapping sequence and then the camera failed to take an image because the 12V power was interrupted (12V power is no longer used just for cooling on some of the newer CMOS cameras) – I just couldn’t understand what was happening, 35-45 good solves (I tried varying the number of points in the mapping, thinking that would help) and then it hung.   The break was only at a certain cable angle and then the power would return when it was back in the APPM starting position.  I was in the kitchen working remotely and I couldn’t see the problem that reappeared four times.)  It took another night of troubleshooting a couple weeks later to figure the power problem out.  In the meantime I followed the suggestions from forum participants for my full frame, high MP camera of doing only a ‘½ by ½ center’ frame capture to speed the download – this is selectable in APPM under ‘camera setting’ – which would make sure my downloads weren’t falling behind and creating a problem.  I was already doing Bin 2 platesolves which also seemed to speed the process.  (The other recommendation, which I followed, was to download the 64 bit Beta version of SGP.)  My last two times out with my primary optical train and this configuration (and a new 12V power cable), everything went very quickly and successfully.

 

I don’t know your setup, but you may be interested to know that when I first started with APPM, I was using a Nikon DSLR with SGP.   The instructions from Ray are to set the recording in SGP from the DSLR to FITS images.  My initial attempts to try ‘FITS + RAW’ (thinking that was even better) were unsuccessful.  Choosing ‘FITS’ as instructed  was the cure.

 

A final lesson learned.  I went back to my Nikon DSLR to try a different image train and mount last weekend.   I had difficulties with SGP (64bit) downloading images from the Nikon – even though it showed being properly connected and powered on.  In fact I could download JPEG images for the frame and focus module, but couldn’t download or record any FITS files during an otherwise smoothly running SGP sequence or for APPM.  I received an error from SGP that it couldn’t download the frames and a dialog box saying that some files could not be found and might be restored if I re-installed the software.   I incorrectly thought the reinstallation recommendation was for SGP and I reloaded it without any effect and before giving up.   It turned out to be the ASCOM platform that had the files and needed to be reloaded.   So I went ahead and updated from 6.4 to 6.5SP1 and everything worked well after that (although at that point I was troubleshooting in my basement the following day!).  I setup and ran through a sequence (without guiding) and it worked fine and downloaded images without protest.

 

In general, to get things off to a good start and make sure I have all the right settings, I do the following (regardless of which camera or AP mount):

 

-Focus routine in SGP with Lum filter (or OSC/DSLR)

-Run a ‘Solve and Sync’ in SGP with Lum filter (or OSC/DSLR) to confirm all is well on the SGP end (platesolves using Bin2)

-Open APPM, show points, connect ‘scope’ and ‘camera’ (through SGP)

-Run about a 68-85 point model to cover the partial sky that I can image in (2-3 points per minute, depending on mount and slew speed)

-Accept the model and disconnect the ‘scope’ and ‘camera’ (SGP) from APPM

-Start my sequence

 

This results in excellent pointing and good guiding.  (Guiding improves even more with a good polar alignment.)

 

Hope this helps.  One amateur’s approach.

 

Cheers and clear skies.

 

Greg

 

p.s. I know you asked about how many points for a portable setup – I didn’t answer that and I am interested in that answer as well because right now I have the luxury of 120VAC and will want to use APPM at dark sites as well and not unnecessarily deplete my battery.

pulseguide option in SkyX #ASCOM_V2_Driver

arenslo@...
 

Hi All,

I'm using the AP V2 ASCOM driver with SkyX to control a 900 GTOCP3 mount on a windows 10 machine.  Does the AP driver support the 'pulseguide' option on the 'guide using' pulldown in the SkyX autoguider tab?  If so, does the group recommend using pulseguide rather than the relays and thus ditch the extra cable?
  
Thanks, Adam

My only suggestion is that you can try increasing the timeout in the
AP V2 driver. APCC uses a third-party component for the virtual ports
in APCC. The component is exactly the same for both APCC Standard and Pro, and there should be no reason that higher virtual COM port numbers would act differently than lower port numbers.

I modified the sample horizon file you sent to me and now have the horizon for my location input into APCC PRO.
But now I have a new issue.

I have been using APCC Standard for years to control my AP1600 using
SkyTools PRO V3 and now SkyTools V4 Imaging. I have the mount
connected to the computer using the
Serial/USB connection on COM3.
I have two Virtual Ports created - COM6 and COM 12. I have been
connecting SkyTools to the mount using ASCOM V2 Telescope Driver -
v5.30.10 on COM12 and occasionally I get a lost communication error
message, SkyTools shuts down, and I then have to restart SkyTools
and reconnect it. I thought that maybe since I was on COM12, that
was the problem. So I created COM31, went into the ACSOM V2
Telescope Driver setup for SkyTools, changed the COM
port from 12 to 31, checked the port and it was found. But when I
went to connect SkyTools to the mount, a connection could not be established.
I eventually went back to COM12 and it connected right away.

Any idea what the problem could be? I would like to use the higher COM numbers if possible.

Subject: [ap-gto] APCC PRO and Virtual Ports

Ray,

I modified the sample horizon file you sent to me and now have the horizon for my location input into APCC PRO.
But now I have a new issue.

I have been using APCC Standard for years to control my AP1600 using
SkyTools PRO V3 and now SkyTools V4 Imaging. I have the mount connected to the computer using the Serial/USB connection on COM3.
I have two Virtual Ports created - COM6 and COM 12. I have been
connecting SkyTools to the mount using ASCOM V2 Telescope Driver -
v5.30.10 on COM12 and occasionally I get a lost communication error
message, SkyTools shuts down, and I then have to restart SkyTools and
reconnect it. I thought that maybe since I was on COM12, that was the
problem. So I created COM31, went into the ACSOM V2 Telescope Driver setup for SkyTools, changed the COM port from 12 to 31, checked the port and it was found. But when I went to connect SkyTools to the mount, a connection could not be established.
I eventually went back to COM12 and it connected right away.

Any idea what the problem could be? I would like to use the higher COM numbers if possible.

Yours truly,

Jack

Re: APPM model how many points portable?

Edited

My mirror is locked in place and I am using a moonlite focuser. I’ll reduce the failed solve time allowable and run another set tonight. I just don’t want to use my limited time on extra points I won’t really need. I’m not sure how to only do points around my intended target. Once again my goal is a little more speed as with my schedule I need to be in bed by 8, which is sunset.  The good thing is that I put a telefgizmo cover on  and leave the scope in place over multiple days if the weather permits.  This is just for when I’m only going to do a night, or two.

I have also been thinking about using SGP and ASTAP.

Fwiw: I have been assuming APPM (?) uses SGP to capture and plate solve, and SGP in turn uses ASTAP to do the plate solve.   

... but I'm far from knowledgeable on this, tho I would like to confirm this works or not without burning too many cycles ... But I'll probably just try it sometime soon.


Also fwiw I'm still on the SGP learning curve, along with a new camera.  Was using maxim-dl, but I don't have full pinpoint.   (And I've been avoiding TSX from a bad experience with it in the past, which is likely resolved.)  I am almost 100% open at this point for image acquisition apps as long as they don't break the bank or my brain.   e.g. Voyager has been noted in other forums, however it seems to me SGP is more intuitive, and maybe is more supported... and afaik APPM does not work with Voyager.


Point is:  there seems to be many variations/options for software these days, which might have varying performance and capability levels.   It would be good to know what works well (at this point in time).

I also am realizing "what works well" may depend on the imaging hardware one is using - whether ascom-only or natively supported.

E.g. I'm currently moving to an Ascom-only camera (at least I believe there isn't native QHY driver integration with with Maxim or SGP).

The upside is the new camera seems to have blazing download speed compared to the ST-8300M I was previously using.


thx .. this is a timely thread for me, btw.

My experience is that points that fail are near the edge of my horizon limits anyway...where I am unlikely to image.  I reduced the time limit on plate solves to about 20% greater than the solve time for most points.  This results in less time lost for points that may fail anyway and still produces an overall robust model with 200 points in about one hour.

A variation would be to reduce the the horizons for platesolving in APPM.

Finally, build a model ONLY for that portion of the sky you plan to image.  This has been discussed before.  Ray has improvements for this approach in the future.

Hi Roger,

Hello, looking for opinions and guidance for how many points to model. There are a lot of topics on this but none of
them seem to answer my questions. I set up each time in my backyard in the same place on an ATS portable pier.
I'm using APCC Pro, 1100GTO, Edge 9.25 with OAG and SGP. My pier is within I would estimate the same few inch
square each time its set up. I did a 93 point model last time because I knew I would have several nights to image and
it worked great. The problem is that with a couple failed points that went to all sky solve it took well over an hour and
a half using SGP and platesolve 2 as my plate solver.
One point per minute seems very slow, even with a few missed all-sky plate solves. You should be able to get 2-3 points per minute.

To answer your question though, your results will depend on your individual setup. If your mirror is not locked down sufficiently you might be wating your time doing too many points.

My question is: Just use the 93 point model since its almost in the same spot? If not, how many points to model
when I will be guiding? My problem is that summertime dark isn't until about 8pm, and I get up for work at an early
0345 every day, so if I want to just do a night or two when the sky is clear for just a night or two, what should I do?
Is there a minimum number of points? Can't dedicate a couple hours to get a pointing model because I have to hit
the sack early (ish). I know an observatory would be the answer, but in my yard that isn't happening. Thanks for
your experience.

That was only my second time using the mount. I had 3 fails which went to blind solve with a 5 minute limit on those solves, so that is 15 minutes right there. I’ll probably reduce the blind solve fail time limit and just drop a few points if they fail. So don’t judge anything by me, I’m just starting out.

My 1100 is due this summer so very curious also, as I will set up each night and tear down, often with a C11, sometimes a 4” refractor.

 

Right now with a MyT I do one large model, then a recalibration each night which takes 10 minutes.  I understand that’s not exactly possible with the AP mount.


One thing from the MyT experience and an SCT – unless you have the mirror locked, the point of diminishing returns gets reached fairly quickly in terms of number of model points and increasing accuracy, as with mirror movement there is an inherent lack of repeatability of getting back to any area of the sky.  Getting a model that gets fractional arc second precision with a scope that’s not repeatable except maybe to 5” or more is not very useful.   One day I may get a different focuser and lock my mirror but in the meantime I accept that lack of precision.

 

But spending 90 minutes a night building a model will be a real bummer.   Is it a plate solve issue?   TSX only takes a second per image to solve.  I really do not like TSX in general, and glad to be getting away, but… 90 minutes?  

 

Say it ain’t so!
