I didn't realized it comes in a set of 3 power cables using different power connectors. It will work for your Mach1.

That’s actually on my list of nuisances to research, I was going to see if someone had a longer spring, but wasn’t sure if the cavity inside was large enough to fully close.

 

I put bright white tape on mine at the point where the clamp clears the opening so in poor light I can tell when I have them all opened and can drop in a dovetail in Park 3.  I unscrew a bit and pull with my finger until they align; also keeps me from unscrewing so far the knob comes off.   Here the middle one I pulled to the left with my fingers, the top is where the spring quits pushing out.

 

I was just so glad to switch to a saddle that you can drop in I didn’t worry too much – the Paramounts have to be threaded from the end, no drop-in at all.

 

I did wonder if this is by design or just an oversight.  If someone finds a source for a longer spring (and confirms there is room), please do post.

Dovelm162 springs too short or assembled wrong?

Tom Blahovici
 

Hi
I received my dovelm162 saddle plate for my new ap1100 and it appears that the springs are too short.
If I put the saddle horizontally, the clamps hang down into the way of the telescope dovetail making it very difficult to move all 3 out of the way.
Now I can fix this by using two of the springs or there is a washer on the knob side that if I put on the spring side it fixes it. However then it doesn't close very much.
Something is not right here....
Is this made by losmandy? If so. again, defective parts from them....

It will connect to CP3 power port but other end of the cable uses power pole connector. Do you have power source that uses power pole connectors?

Re: Interactions Between Keypad and APCC Orthogonality Models? #Mach2GTO #APCC #Keypad

Hi John,

I am looking for some 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:
You should not simultaneously use an APCC model with the keypad model, as they do not know about each other!

#Keypad

Hi all,

I am looking for some 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 pointing 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 normal pointing model. It would simplify / speed up
plate solving on both sides of the meridian. Ideally, for a quick portable imaging session, 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. I will
be guiding for these sessions and since they involve only a single target, plate solving will suffice for the
evening's only target.

APCC Pro 1.9.0.7

Ray Gralak
 

Hello all,

We want to announce the availability of APCC Pro 1.9.0.7.

The changes include a couple of minor fixes:

1. APCC Pro - Fixed - APCC can once again launch APPM and plate-solve+RCAL to the configured equipment.

2. APCC Pro - Fixed - there was a sign error in two cases adding external declination rates from the ASCOM driver.

You can download APCC Pro 1.9.0.7 directly using the link below or Check for Updates in APCC Pro.

Best regards,

question about power cables (Mach 1 power cable ).

nicholas
 

I believe I need a replacement cable for my Mach 1  mount with a CP3. I therefore ordered item CABPP123SET. 

I would like to 1) make sure this is the correct power cable that connects to the 12v port on the CP3?

Are there other power cables that can be used that are off the shelf and can be purchased locally to where I live [San Diego.]

Thank you!!

Not exactly. This was before I balanced the Stowaway taking off the 18# weight and moving the 10# all the way up.

   Ok, I think I finally get it. While the Park position is encoder based, the actual RA slew position depends on time. That might need an altitude adjustment to compensate. Thank you for your patience.

Karen,

Thank you for the clarification. Even though it took ~ 2 years (2 years 5 months to be precise)  but most challenges were beyond AP's control like Bill Long points out, AP did a great job; the timelines were skewed due to acts beyond anyone's control, including delays of ~4 months due to Covid related delays with Renishaw. We all hope that the worst is behind us.

what factors will cause the Altitude adjustment portion of your improved 2020 polar alignment procedure to see largish errors in Altitude? I was seeing between about 40 and 50 arc-minutes error after having carefully leveling the OTA at Park 5.

Hi Shailesh,

Here is a link to a post with my solution:
<https://ap-gto.groups.io/g/main/message/79079>

It's a tight fit...I have to take the saddle off and rotate the altitude axis just about all the way.  But it's nice and small and _very_ protected.  Pelican doesn't mess around when it comes to good cases!
