In the meantime, as long as it's roughly balanced in DEC, is the mount OK to use?

No.

Have never done that. Guess I’ll have to read up on it somehow. Ray says it’s in APPM.  Then I would prob have to create a model correct? 

In a quick web search there are some freeware pkgs that advertise they do all sky plate solves without even an active internet connection.  Not sure how cumbersome they could be. Need to look into it. 
Looks like I need a model, I have APCC Pro on my Mach1GTO and 1100GTOAE.

I have a AP 130EDF on my Mach1GTO and this evening I had set a 2 hr meridian delay and accidentally slewed to an object that had the mount just gently nudge the pier to lose its calibrated position. I could not get images to plate solve after that since the mount was not where it thought it was.
 
Is there any way to remotely send it to a known position or any way to recal without having to go to the observatory and level off at my Park 2 position?

You have good eyes if you can see the Soap Bubble in my regular full frame image.  It is there, but barely visible.

I did a starless version and the Soap Bubble is much more visible.  Here is a link to a cropped starless version:

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.

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

jypeng@...
 

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!

It's pretty straightforward to install, but you need to pay attention to your imaging scale and download the correct catalogs (the default range is pretty generous so you may not need to adjust, but for longer or shorter focal lengths, just look closely)

it's essentially a local version of astrometry.net

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.
