You can easily open these folders from APCC and APPM.

 

For example, from APPM, you can open a Windows explore instance in the folder with the PNT files and logs by clicking the menu: File->Logs Directory as shown in this screenshot:

Re: Does your Mach2 setup look like this?

Jeffc
 


Here’s the Mach2 with the Meade12-ACF (this is an early version with the smooth glossy tube and the “RC” label).  Also attached is a Clement focuser (kinda heavy) , Lumicon GEG with reducer lens, some AP 2.7” extensions and the QHY-268m camera & filterwheel.   On top of the OTA is a UPBV2 which weighs nearly nothing.

Re: Question: ROLAND’S GTO QUICK STAR DRIFT METHOD - 2020 VERSION

John Upton
 

Roland,

   Thanks for the quick answer regarding orthogonality not affecting the polar alignment method.

This question is quite easy: The parks are governed by the time you have set in the keypad (or your laptop). If you are off by 1 hour, the parks will be off by 15 degrees in RA. For every second that you are off, your park positions will be off by 15 arc seconds.
   This was a bit of a surprise to me but after thinking about it, I think I understand. It would have to work this way for non-encoder mounts to work correctly and there is no reason to rewrite the underlying code for encoder mounts. I had been in an encoder mindset and assumed incorrectly that the mount Parked based on encoder positions. I see the error in my thought process.

   To bump my question in the second post, do you or Ray have any clarifications regarding the interactions / interoperability of the Ortho Model performed by the KeyPad versus the pointing model created by APCC? The questions I want to understand are:

  1. I assume the APCC model takes precedence when a KeyPad Ortho Model has been built. Is that correct?
  2. Does the APCC model erase the results of the KeyPad Ortho Model or simply override it?
  3. If the APCC point corrections are turned off, does the most recent KeyPad Ortho Model once again take effect or does a new one need to be built?
   For some observing and simple single object imaging sessions, I think I would like to just have the orthogonality error corrected without creating / running a pointing model. Ideally, in that situation, I would prefer not to have to rerun the KeyPad Ortho Model at the beginning of each session when I don't want to run APPM.

Hi Roland

I don't have any ringing with my setup but I was wondering if having those cable bundles just hanging off the back of the cameras in your setup can cause guiding issues with non-AE mounts. 

I use a similar cabling arrangement as yours with my non-AE 1100 mount (see photo), but I suspected that the long, free hanging cable loops might have created some guiding issues, so I started tying them off at the mount to make a shorter loop to minimize the weight pulling on the camera.

Re: Does your Mach2 setup look like this?

Quite the setup. The Mach 2 is an amazingly good performer even under significant load. I personally think it's the best encoder mount on the market in it's price range and it's not even close. Would love to see some raw subs from the Mak Cass Astrograph sometime.

I use off-axis guiding and lock my focuser, so there is no effect from cables dragging. Might be a problem if you use a separate guide scope?

Re: Question: ROLAND’S GTO QUICK STAR DRIFT METHOD - 2020 VERSION

Roland Christen
 

First question; Yes it works even with horrible orthogonality.

Any idea why the Altitude had to change considerably after leveling in Park 5?
This question is quite easy: The parks are governed by the time you have set in the keypad (or your laptop). If you are off by 1 hour, the parks will be off by 15 degrees in RA. For every second that you are off, your park positions will be off by 15 arc seconds.

This is also a way to check your exact local time - simply change the time in the keypad by a minute or so (or even a few seconds) and park again until your park position is exactly parallel to the earth. Presto, you have now synchronized your time to the stars.

Subject: [ap-gto] Question: ROLAND’S GTO QUICK STAR DRIFT METHOD - 2020 VERSION

Hi,

   I have a question about Roland's Quick Star Drift Alignment Method as documented in the Mack2 User manual. (Appendix C on Page 41.) I tried it out the other night and all seemed to go pretty well. The Azimuth Alignment step went perfectly and was easy to perform. I did use a shortcut of sorts by simply doing a Plate Solve and Recal just West of the Zenith before slewing to a star in the south just West of the meridian.

   My main question is whether (or how much) this method depends on having previously corrected for any Orthogonality / Cone Error of the OTA. I had quite a bit of East / West offset difference when I performed the second stage of the method to dial in the Altitude adjustment. I was surprised at how much I have to change the Altitude axis (nearly a full turn of the Altitude adjuster) to move the star N/S to get back to the crosshair. I had started by using the Park 5 / Level OTA initial adjustment before beginning this method.  Any idea why the Altitude had to change considerably after leveling in Park 5? (I  pretty much trust the Level since I have calibrated it carefully and get exactly the same repeatable reading when turning it 180° with less that 0.05° reading difference.)

   So, back the main question; does this method work equally well even in the presence of orthogonality error? I really like the method as it is very , very fast but wonder about the E/W star offsets I see when adjusting the altitude of the RA axis in the second half of the procedure.

Re: Question: ROLAND’S GTO QUICK STAR DRIFT METHOD - 2020 VERSION

John Upton
 

Hi, Again.

   I see a typo in my first post. The mount is a Mach2, of course, rather than a Mack2 -- although it seems as a stable and robust as a Mack truck.

   I have a related question about Orthogonality error. When you use the Orthogonality (Ortho Model) correction method in the KeyPad to correct for orthogonality, does this "stick" in the CP5 control box or KeyPad? (I cannot find where I read it but think the correction value is actually stored in the CP5 box. Right or wrong?)

   So, if I perform the KeyPad Ortho Model correction procedure, I understand that creating an APCC model will override it. However, on a subsequent night after having moved the mount, does the KeyPad's orthogonality correction apply once again if a new model is not created (since the old model will not be valid)? Or, do I need to rerun the Ortho Model procedure on the KeyPad again?

   If the KeyPad correction is always present, then it should help with the E/W offsets I see when performing the polar alignment method in the first post. (Or, I could be completely off base.)
