Re: Recal remotely?

Hi Jim,

However, the question still remains, should the clutches slip due to whatever reason, is there any way to restore
calibration without a physical presence In the observatory for a non encoder mount?
I think Dale already answered the question.

Assuming you can aim the scope at dark skies you can do an all-sky plate solve and RECAL. The best way to do that is with APPM in APCC Pro.

Thanks for the suggestion. I have that one downloaded and will try it the
next time out.

It would still be nice if APCC could do this, though, since it already has
access to the GPS data.

You can use a utility called GPSTime to update the system clock after
booting but before starting APCC.

Because your USB GPS device is accessed via COM port, and COM port access is
exclusive to 1 application at a time, you cannot have GPSTime and APCC using
the GPS at the same time, but this will get you an accurate sync.

If you don't need to have APCC connected to the GPS device all the time, you
can continue to run GPSTime in the background and it'll continuously keep
the computer's clock in sync with the NMEA time sentences coming off the
GPS.

Would it be possible to add a button to the GPS tab in APCC to sync the

very accurate location and time information. The location information is
easy. I have a USB GPS receiver and APCC can read it and create a new site
based on the current location. To get an accurate time, though, I'm pretty
much manually correcting the time in the computer based on my watch (which
syncs nightly to an atomic time source). Since the computer is dedicated to
use with the imaging setup, it's often been powered off long enough for its
real time clock to drift. At home, it's no big deal because it syncs with
an internet time source almost immediately after booting. In the field,
though, it would make things easier to be able to automatically update the
time from the GPS.

Before I attached the CCD to the scope, the DEC axis was fine. So this is a recent development.

Re: First light with Mach2GTO

Great shot Jian Yuan,

I have taken some images of the crescent in narrow band.. although I only have a couple hours per filter..   16 hours is a ton of data! I may get 16 hours over a few years (smile).    I hope to get mine processed one of these days... the tech industry hasn't seen any slow down, an in fact it seems to be all the more busy.

How do you like the TEC 160?   I have been thinking of moving from the 140 to 160.  I really need a permanent install for the 180 as for my old body I'm not sure I could even mount a 180.    I really love refractors.

Getting time and location information into the keypad from the mount.

W Hilmo
 

When I was at a dark sky site last week, I took both of my AP mounts.  The AP1600 with encoders was set up for imaging, and the AP1100 was set up for visual use.

I set up the imaging system first.  I updated the location from a GPS receiver through APCC and set the time from my watch (which syncs nightly from an atomic time source).  I then did a daytime polar alignment to complete the mount setup.  I then plugged in the keypad and used the menu option to get time and location from the mount.  When I did this, the time and location matched what I expected.

I then disconnected the keypad, moved it to the AP1100 and initialized the mount (from the keypad, with no computer).  I then double checked the location and time information in the mount.  I then double checked the information from the mount, expecting it to match what it pulled from the AP1600 a few minutes earlier.  The time was very close, but the location information matched the last time I used the mount, at a different location.

I was sure that I'd seen this work correctly before, but I tried a couple of times to get the location information from the AP1600.  Each time, the location information was correct in the keypad when connected to the AP1600.  But after power cycling the AP1100 and initializing it from the keypad, I kept getting the previous site location.

Is this supposed to work?

Next month, I am planning on initializing the AP1100 from Luminos, on the assumption that my phone will have correct time and location data.  But it would be nice if I could understand why moving the location information between mounts using the keypad, does not seem to work like I thought it did.

Thanks,
-Wade

However, this does not explain the issue APCC not being able to find the CP4 box on the network.
APCC uses a UDP broadcast message. Make sure that your firewall allows that.

And again (as I said :-) make sure you disable any unused network adapters on your computer in case the UDP broadcast is being sent by windows out the wrong network port (s).

Hi Ray



It looks like the Windows update may have changed the decimal point setting. Have you tried changing the
Windows setting to swap "." and "," so that they are equivalent to what the mount expects? In the above log
messages the mount will not understand a comma in the RA and declination values.


I have changed the settings as suggested.
Also switched to TCP.
I will now have to wait for clear skies to confirm.

However, this does not explain the issue APCC not being able to find the CP4 box on the network. I tried that
again after the TCP switch: it consistently returns no result - Win10 feature update may be a reason for that. I'll
stick a yellow note on my computer screen "/!\ Stay away from Win updates on the imaging computer".

Thanks a lot for your feedback and insights.
Clear skies,
Rodolphe
