Re: New version of APCC

Greg Salyer
 

To be perfectly clear, although I think being able to park with the scope point down would be great, I'm not asking for it. It seems like the programmer effort would be huge. Moving the scope to such a position would be tough but handling unpark with the scope in such a position seems like a programming nightmare. Much worse than the much simplier Park 1 vs 4 vs 5 story.

I've always wanted to park my scope pointing straight down to avoid dew forming during storage. However, it would require APCC to do it in a very careful, precise manner to avoid collision with the pier. It would be a great function but I doubt if enough people would want it to justify the programming effort.

Is there consideration to update apcc pro to allow the mount to be parked at a negative altitude? I am permanent and want to park that way to mitigate dust on the primary.

Re: Inverter issue

Christopher Erickson
 

Every power conversion has an efficiency loss that will be someplace between 5 and 30%. Average being about 15%. Two conversions (13.7VDC->120/240VAC->12VDC) will likely have twice as much loss, plus the electronic components used in the conversions may be temperature sensitive and malfunction in freezing temperatures. Especially if they were designed for indoor applications only.

You can get an estimate of how efficient a power converter is by how warm it gets when working. The warmer it gets, the less efficient it is. That heat is lost energy.

Usually best to try to minimize power conversions in the field. No sense using battery power to heat the outdoors. Lots of hot power conversions in an observatory would be bad too. Regardless if the observatory is on grid power (mains power) or not.

Don is correct, although typically if you pull too much current out of an inverter it will blow a fuse or breaker.  Try running the mount right off the battery if you can make up a cable.  Fusing that is a good safety precaution.  It is also possible the the AC to DC converter has a bad connection which is showing up in the field.

The car inverter is likely square wave output which may not work for the mount.  And BTW, if the main inverter is failing and putting out a poor waveform, some devices will work, and some will not.

Re: : [ap-gto] Park 1

Christopher Erickson
 

There is a third party GPS solution for AP mounts from StarGPS.ca that will keep the hand controller time, date and location precisely set every time it is powered up. It can only do this during power-up so it won't help with drift over time in a fixed observatory where the hand controller could be powered up for weeks or months at a time.

"If you unpark the mount from Park1 and begin tracking sidereal, in a few seconds the mount will be in a counterweight up position, which you may not realize."

I'm well aware of that.  Not an issue in this circumstance.  I adjusted the keypad time as closely as I could to conform to the "atomic clock" in the observatory.  Even so, when I used the keypad to send the mount to Park 1, it went to the equivalent of Park 5.  As it is now, the camera is back on the scope, and I'm back to operating with APCC, which is set to give me Park 4.  I'm having a camera problem (QSI), and I thought it was suddenly resolved while the camera was setting on the computer desk.  So I was emboldened to remount the camera on the scope.  Too soon.

Thanks. I did that, but it unparked the mount and started tracking. That's when I discovered "Don't unpark" the unpark choices on the next screen. I selected that, and the next time I ran APJog, the mount was still parked.

Problem solved!

Re: Can I launch the ASCOM driver standalone?

Dale Ghent
 

An ASCOM driver instance must be started by a host application, so there is no way to practically operate the driver on its own. For your purposes, I would recommend using the APJog utility that is installed with the AP ASCOM driver. It’s just a lightweight directional keypad and of course it’ll instantiate an instance of the AP ASCOM driver in the process.

Re: Mach2 Modelling question

Roland Christen
 

Right now the modeling we have is a routine done in the keypad, which is very simple. It has actually been in the keypad in a different form in the past called Smart guide, but it was not well known so nobody ever used it. So now we have modernized this in the form of a curve fitting modeling that resides in the CP4/5 controller and is activated (points fed to the controller) via a simple keypad routine. It is so simple even I can do it. Adding modeling to the keypad was a goal for some time because even the cheapest import mounts had it and we seemed to be behind the times.

Can it be added to APCC? yes, but why? APCC already has provisions for extensive modeling that builds the model automatically while you go eat dinner or talk with your friends at a star party. The keypad version is manual and doesn't include some of the terms that APCC modeling has. It's easy, but requires your time to sit at your mount, acquire stars and manually enter them into the CP4/5. APCC does it automatically.

Subject: [ap-gto] Mach2 Modelling question

I know Mach2 will have a new modelling method. 
My understanding is that it will measure drift along the objects path and then apply corrections as the mount moves through the new sky positions.

Sounds similar to the method I used on my ASA DDM85 mount.
This is great method for unguided tracking.
It will works very well for portable users since it does not require a standard model.

I found real benefit using this function along with the standard model in my permanent observatory.

My questions are

1) Will the new method be and added to APCC or is it only keypad function for the Mach2 ?

2) My only complaint with ASA method was that it only worked their automation software.
It could not be used with other automation packages such as Voyager, SGP, CCD autopilot , etc.
Is there a chance you will add this function to APCC so it can work with automation programs using the other mounts, 1100 and 1600?

Re: : [ap-gto] Park 1

Roland Christen
 

Park1 points to the north horizon with scope on the west side. Park 5 points to the northern horizon with scope on the east side of the mount. Both parks are correct. If you unpark the mount from Park1 and begin tracking sidereal, in a few seconds the mount will be in a counterweight up position, which you may not realize. So if you then go inside to have dinner, and forget that the mount is running and go to bed, at some point, perhaps a couple hours later, the scope may be up against the pier and the mount is stalled. With Park5, it takes 12 hours of tracking before you get counterweight up position, so there's plenty of room for error.

Ray, I had read somewhere that the Park5 was planned to replace the Park1 which was not always correct.
but at the sight of the documentation I do not understand too much the interest of this park5 which is rather the park4 upside down.
I made my room with the target of park1 which also works well at home and therefore park 4 or park5 is kif-kif as far as I am concerned. I think that with the mach2 all the parks should work perfectly and even that we can choose our own park.

The ASCOM driver send time and date to the controller, but this does not update the keypad's date and time.
You can update the keypad time by simply pressing "Get Time From Mount" on the keypad menu after initializing the mount from your ASCOM driver. This way the keypad and your computer are synchronized time-wise.
