Success. Was a perfect fit.  Here's a before and after shot:

Thanks for the help and suggestions.  


Re: Recal remotely?

Clement Elechi
 

I have used ASPS. It does the job.  I now use ASTAP which has its own catalogue and solves extremely quickly.  Blind solve and "sync" should do it for you.

Thanks, Rolando! I've reached out to AP for the repair/replacement kits. In the meantime, as long as it's roughly balanced in DEC, is the mount OK to use?

Hi Dean,
I saw your crescent image in the astrobin and confirmed that you got Soap Bubble too last week. 
Thank you,

Re: First light with Mach2GTO

Hi Terri,
I really like TEC 160 which is well built and good quality the same as A-P's products.  It fits Mach2GTO very well. TEC 160 weight and length is manageable for me and I keep 160 on the mount in my courtyard covered by TeleGizmos360 in the summer. I will mount it on/off during the rainy season.  I think you should have a permanent installation for 180. 
Hope to see your crescent image too.
Thanks,
Jian Yuan Peng


Re: APCC Feature Request: Sync time from GPS?

Tom K4XV
 

I too suffer from the same problem.  Good thought Dale but the APPC GPS app also supplies environmental data for APPM.  Time sync would be very nice also.


Re: Recal remotely?

 

CORRECTION

from dc3 website:

The time limit for the Astrometry.net all-sky solving engine is ten minutes. During routine tests, we have observed an occasional image that ran for over 5 minutes then solved. The ten minute limit applies to both the online and local all-sky servers. Don't give up, just wait to see if the solution comes back!

Subject: [ap-gto] AP1200 DEC Stiffness

Good Friday morning all,

I had our AP1200 configured in our backyard observatory for imaging with a 6" f/8 refractor for a little over a month. I reconfigured it last night for visual/planetary use (removed the CCD and external focuser).

I was surprised at the stiffness of the DEC axis compared to what it had been prior. RA axis was fine; it showed the slightest hint of imbalance. The DEC was so stiff that I could barely detect signs of imbalance.

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

Regardless, the mount still worked fine - after a quick session imaging the Moon, I discovered the Double Star feature of the handpad and the mount showed me a few beauts.

Help?

Thanks,
Eric

Been there with my 900...

What I've done is slew to a known star/object in the area, center it, and select that object in my planetarium software and send a manual Rcal (a "Synch" in their terms usually).

To double check, do a quick plate solve.

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.

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.

Hello,

I just got back from a trip to a dark sky site, and I have a feature
request:

Would it be possible to add a button to the GPS tab in APCC to sync the
computer to the GSP time? My scenario is that I am setting up at a remote
site, without any cell or internet connectivity. I always set up during the
day and do a daytime polar alignment. The daytime polar alignment wants
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.

Thanks,
