I replaced my Mach1 with a 1200 and have not really had any problems. I sync with SGP by centering a star selected with coordinates. My mount did get "lost" after I did some adjustments using the hand controller. I released the clutches, put it back in park 5, reinitialized, and all is ok. Goto's are very accurate.

Unpark from Present Position is more accurate.
In fact if you are permanently set up, put the keypad in Autoconnect YES and your unparking will be automatic and more accurate.

Hi All
I'm setting up my observatory with all the software.  My 1200GTO mount with CP4 is having pointing issues.  I saw that it was recommended that I select Unpark from position 4.  I tried that with no difference.  Is my keypad database corrupt?  Should I reload my database?

Thanks

Carl

Hi Ray
I tried unparking from APCC.  When I chose unpark from position 4 I got a warning asking if I was sure sure about unparking from 4 because I risk running I to pier.  I hit OK then resume from last park went into window and greyed out.  I'll check my version.

Am I supposed to put the mount in park 3 when I select resume from park 3?  I normally use position 4.
Thanks

Rolando I find your comment disappointing assuming that I have done something like this. I have never left the lever to any other position than fully engaged. As a matter of fact I don't touch my mount, it just stays put and as you might remember, these latest problems started as an electrical issue (connection) when again, nothing had changed. The only time I have adjusted the backstop was months ago when I had the weird plate solving problem. After that the mount worked for months before this latest issue occurred.

Hi Carl,

Are you unparking from the AP hand controller or the driver/APCC? If you are planning to use Windows software, you should unpark via the driver/APCC.

Also, try unparking from Park 3 instead of Park 4. Park 3 has the scope pointing at the celestial pole and counterweight shaft pointing directly to the ground. If you are using APCC then power cycle the mount and let APCC initialize the mount.

BTW, the latest APCC Pro version is 1.8.4.1. The link is here:

Hey Carl!

Hope you get this resolved quick, looking forward to see some images from you again. As for the problem, is all the mount/keypad firmware up to date?

Hi Bryan
I'm guessing maybe 45 degrees or so to the East, nowhere near close.  Checked my timezone, set at 5(Eastern time).  I never could get mount to find a star past transit, but only stopped trying at 12:30 am.

Yes the error is repeating.   When I go to park 4 the ra looks to be in park 2 with counterweights down and dec correct.

When I synch, I use TheSky, the mount looks to be over correct object but when I slew ota always goes to west side of mount. If I try to use keypad to synch I get error in APCC about target error too far in ra to synch.

Thanks


Re: 1200GTO Pointing Issues

Carl

Please provide more info about 'pointing issues'.

For example,
How much is pointing off on the first star?
Does the error change after a sync?
Is the error repeatable?

It is difficult to diagnose 'issues'.

APCC-Pro manual temperature/pressure entry question

Bob Benamati
 

Ray,

For some reason, the temperature entry box for the pointing model has disappeared. I thought maybe updating to the latest version would fix it, but unfortunately it hasn't. The pressure box IS still there, so not sure if this is truly abnormal (screenshot attached).

Not having a weather station, I originally created a model at 10C, and that info is what is still populating APPM whenever I've redone a model. Not sure where APPM is drawing that from and if I can/should change it when I do go to redo a model in the future.

Overall, APCC has been working wonders even for my old 900 CP3, so this is just more of a curiosity than an urgent need for resolution!

Thanks!
Bob


Re: Mach1 and GTOCP4 Yellow Light

Roland Christen
 

We believe the worm was damaged when you left the unlock lever in the half way position on the RA gearbox. that lever has to be fully seated clockwise. Also make sure that you read the instructions in the manual for setting the backstop. If you put too much pressure on the backstop adjustment, you will produce more worm tooth wear. Setting high pressure on the backstop will not reduce backlash, in fact it will tend to make it worse. The backstop should be set gently, not with huge pressure or force. Please read the instructions carefully if you make any adjustments to the worm mesh. The manual is available on-line as well as the written form that you received with the mount.

To put a closure on this, the mount was shipped to AP a few weeks ago and I received a mail today indicating that the issue is fixed. The attached service report states; "Confirmed that mount is not communicating. Unsuccessfully attempted to reprogram the digital board, so replaced and programmed for mount, version P01-14 and Wi-Fi program. Disassembled damaged RA worm and worm wheel and removed grease; removed burrs which were breaking off the worm wheel resulting in slivers."

Looking forward to get the mount back and start the imaging again.

Re: Pier flip before meridian crossing is not possible with SGP and Mach1

Leo Shatz
 

Hi Luca,

Thank you for suggestion. I've arrived to the same conclusion, that meridian flip should be delayed by few minutes to avoid situation where small time difference that can prevent SGP from performing flip at all. I'll setup the flip offset and select parking in APCC as action on reaching meridian limits, so that there will be enough time for SGP to perform the flip and still leave some margin before reaching the limit.

I would appreciate any help, however, regarding testing the issue of early flip with SGP, as I think that current SGP implementation doesn't support it.

With regards,

Leo

Rick, 

On the heavy side then... That’s what I was afraid of. 

For my setup, that would mean 62lbs (42+10+10) of metal, let alone the scope and other A-P gear. Hum... I guess I’ll have to workout harder... ;)

Thanks for sharing your experience.

Sebastien,

I've had the Mach 2 now for a several months and I too was very worried about portability.   My old mount was a Losmandy G11 that would split into two sections and that made the mount very light and manageable.  I live in a big city and I do not have the option of a permanent mount.  I'm very happy with the portability of the Mach 2.   I find it very comfortable.   I cradle the mount like a baby with both arms close to my chest and then set it on the tripod.   The weight of the mount on my digital scale is 44 lbs 5 oz.  That's with the polemaster camera attached and a DOVEDV10 saddle plate.  That's it.  No counterweight bar or weights attached.

Would I buy again?  Yes.  Absolutely and without hesitation.  The mount becomes invisible.

Re: RAPAS on 1100GTO

Phillip H Coker <pcoker36@...>
 

I routinely left my RAPAS installed while using my scope until the night that the mount slewed to the east and hit the North leg of the tripod with the illuminator/battery holder and twisted the back of the RAPAS around. Since then, after polar alignment, I take the RAPAS off.

Thank you, Ben. Yes my cheaper mount had a straight through polar scope and it was truly a pain in the neck. I look forward to using the RAPAS to dial in polar alignment.

Hi guys,

Just a few questions for the lucky owners of the freshly baked Mach2 and Stowaways (or similar size scope)

As far as portability is concerned, would you say it would be "comfortable" (as in "with a bit of reasonnable effort") to move it around (say 30-40 ft,- from the backyard to garage) with the Stowaway (plus cameras, guidescope, etc. (worth about 12-13 lbs) mounted + 10 lbs of C/W? I mean by hand, without tearing it down (except for the tripod).

I know that's an entirely subjective question but thought I'd asked anyway to see what people have to say. 

I also know the Mach2 is spec'ed at 42lbs from AP's website but I could not find if the 10lbs counterweight bar is included in that spec, which would make the mount alone 32lbs and my setup at about 55 lbs, i.e. just at the edge of "moving comfort" to me, as I defined it above. 

It'll help me decide if I'm going to pull trigger when AP contacts me (I'm on April 2019 list) or if I'm better getting a used Mach1 or Myt.

Thanks for your input and clear skies !

Sébastien

Taking several trips and packing the OTA and counterweights separate from the mount, yes, it is easily doable.

Another option might be a wheelie-bar.
