Re: APCC and SGPro Meridian Limits #APCC #ASCOM_V2_Driver

Ray Gralak
 

Tom,

I'm sure it's something I have wrong in the settings and could use some help.
The setting you should configure is the Flip Offset, which moves the mount's flip point East of the meridian limit by the number of minutes you set. This gives the imaging application (SGPro) an interval of time during which it can initiate a flip before reaching the limit. Usually you want to set this at least as long as the duration of your images.

2. Regardless of that discrepancy, The mount faults with both RALIMIT, and West Limit errors 10 minutes
or so earlier. See the third attached image for the faults.
It would probably fix this issue if you configured the mount's home and limits on APCC's Home/Limits tab.

Hey all, looking for help getting meridian flips to work with APCC, Ascom, and SGPro. There seem to be two
problems:



1. APCC limits and SGPro Time to Pier Flip do not seem to agree. APCC seems to think the limit is hit 40
seconds or so before SGPro thinks it's time to flip. See the first attached image showing the difference.
2. Regardless of that discrepancy, The mount faults with both RALIMIT, and West Limit errors 10 minutes
or so earlier. See the third attached image for the faults.

I'm sure it's something I have wrong in the settings and could use some help.

Thanks,

Re: Smart Meridian Flip with NINA #APCC

Hi Joseph,

I've been out in the boonies again for the past week so have been catching up on this thread. It seems you have been having some general issues with APCC that have been sorted out with a settings reset?

If you are able to now try the SMF plugin again, make sure of the following:

- That your .mlm file from APCC is specified in the plugin's options (Plugins > Installed > Smart Meridian Flip)
- That the Smart Meridian Flip trigger is being used in your Advanced sequenced, either in a target-specific Trigger area or in the the Global Trigger area
- That you have reviewed the global Meridian Flip settings (Options > Imaging > Meridian flip settings). I have mine as such, if you want a reference:

Depending on your circumstances, you may wish to adjust the post-flip settle time to taste, and turn on Autofocus after flip if you have a telescope that suffers from mirror flop.

I'm hoping for some suggestions to help restore a functional connection between my computer and the mount. After the latest event that started with a meridian flip followed by pointing issues which then caused APCC-Pro to stop responding. I've gone back through all set up instructions for APCC and the V2 driver but was unable to get the mount to connect correctly. The end result was APCC would only open the then stop responding and require closing using task manager. The V2 driver would also open but the mount was unresponsive to both.

This morning George was very helpful in troubleshooting the connection problem. He came to the conclusion uninstalling and reinstalling APCC-Pro was likely indicated as it appears something may have been corrupted in the event. I reinstalled APCC and the connection problems were still present. I uninstalled and reinstalled the V2 driver as well, confirmed all ports were configured correctly in both programs but that also made no difference.

Currently APCC will open and attempt to connect but the "Connect" window hangs in the middle of the window. Shortly after that Windows pointing icon turns into a rotating circle and APCC becomes unresponsive.

I'm stumped at this point.

We have excellent transparency at our observatory and the sky is really dark. The seeing (star scintillation) is not always good, but the Honders is a medium focal length scope (1160mm) so it is ideal for semi-wide field objects. I intend to go extremely deep with it and will be using the fast optics to gather detail in very faint structures.

APCC and SGPro Meridian Flip Issues #apcc #ascom_v2_driver #APCC #ASCOM_V2_Driver

Tom Zepf
 

Hi folks, I seem to be having issues with getting SGPro and APCC setup for successful meridian flips. In all cases, the mount stops tracking before the meridian limit is reached. There seem to be two issues:

  1. The time for SGPro to flip and the time for APCC limit reached seem to be off by 40 seconds or so in the wrong direction. See image #1 for the discrepancy.
  2. Regardless of #1 above, the mount faults an RA LIMIT about 9 minutes earlier than that.
Any help is much appreciated!

[Edited Message Follows]

Here are some screenshots I handed the log from tonight to Andrew.  I followed the instructions but the guide star was low magnitude. Somehow I had issues with the main imaging camera locking on stars so I did auto select star but in the desired constellation, near Altair.

Maybe this refractor is a large load given the results?  

also often times I see an error message like "RA calibration failed star did not move enough."   
could that be it locked on to a hot-pixel,?

Re: GoTos

fernandorivera3
 

Chip the ultimate method to get rid of flexure from your C14, beyond removing the cheap Celestron orange dovetail, is to mount the scope to a Andy Homeyer scope cradle- they are expensive but built like a tank. Absolutely rock solid.

Fernando


Re: GoTos

weems@...
 

My 900 carries a C14 and 6” f9 side by side and generally gets within 10’ of the target (closer to 7’ when not into refraction near the horizon).  And it can slew from one side of the meridian to the other then be told to return to the starting object, and will get it within 1’.  The planets are a bit off, probably because of clock drift, as I haven’t set it since the DST change.  But It wasn’t close to that until I did a draft alignment for 30 minutes in each axis, and adjusted cone error to less than 1’. It’s on a 12” concrete pier, with a very short rat cage. I replaced the flexible Celestron dovetail with a Losmandy. Every mechanical connection is also really tightened up.

Re: [ap-ug] The Beast is heading to Hawaii..

I don’t know how well the riccardi-honders performance compares to the Canon ultra low reflection lenses, the key is having minimal reflection, which coupled with matched (or compensated to match ) cameras, they’re able to see fainter stars than even the largest telescopes. Fun project. I’d love to try what I call the poormans version of that, 4 or 6 scopes. But I need to learn more about how to analyze scopes for transmission and internal reflection.

Subject: [ap-gto] AP1100AE PHD2 guiding with wind

Been a lot of PHD2 discussion recently, so what's one more... 

Dry season is starting soon here with more clear skies, but it usually comes with some wind.

I realize the real fix for wind is a wind break, but some of us just have to be out in it... 

So far I am getting really good guiding, 0.20-0.30 if the wind is calm and the seeing good.  I've hit 0.18" at times for goodly periods.  Really good, and not very sensitive either, I have tried short exposures, long exposures, with a model, without a model. I am sure I could screw it up, but all the reasonable stuff just works.

But the season change brings me to the question: Is there anything you would recommend changing to respond to light wind, the kind that moves the OTA around a bit, say 3-8mph with a C11 and dew shield on it.  In particular do shorter exposures help, or do they fight the encoders?  Longer?  Bigger min moves? 

I do realize the encoders only "see" movement within the mount's mechanism, not shifts that also involve the tripod, etc.  And some of that movement is brief impulse that bounces back, and some may be an actual shift that guiding has to take out.  It's not a simple issue. 
That's why I am wondering if experience has any guidance for the best approach in calm vs windy?

My first inclination is do nothing, but there are folks out there who have probably seen and fought every problem so... advice?
Linwood

PS. And yes, when Is see a girl with a dog on a bicycle blowing past, I will bring the mount inside.
