Thanks Dale I do mostly imaging and yes I will call AP and get a battery and probably do the chip as well.

Greetings group, been away from observing for quite sometime so basically starting over.

Right now the mount is not accurate in it's slewing even after syncing on a known star/planet. Obviously since this is completely original and the last time I used it which was probably at least 8 yrs ago something needs to be corrected or updated. I had used it quite accurately in the past so being it is a very capable mount for my needs I want to get it back so I can start observing again.
First, some maintenance items:

* New keypad battery, $25 or so. Must order over the phone from Astro-Physics because which battery you need depends on your keypad serial number. The one in your keypad is probably dead.

* Consider regreasing. Should be no problem if you're mechanically-inclined and patient.Your mount likely has the factory grease in it still and after so much time it ought to be replaced, especially if the mount wasn't stored in a climate-controlled setting.

* After replacing the battery, update keypad firmware and restore keypad database. Instructions online.

* If you have a CP3 controller, consider the upgrading it to the V2 chip which is the last of the hardware-based upgrades for the CP3. New capabilities (park positions, probably other things) and bug fixes.

Other than that, there are some creature comforts such as the RAPAS polar alignment scope. Are you visual or an imager?

1. Clean, regrease and remesh gears
2. CP3 v2 or CP4 (maybe)

Does this mean the update will be released soon for owners of the older HB?


Re: Mach2 Hand Controller

 

We have started to ship them out. Daleen or Paige will contact you soon regarding final arrangements. I will be sending an email in the next day or two with additional information.

 

Clear Skies,

What is the latest estimate for shipping Mach2 hand controllers?

Re: Mach2 Hand Controller

 
Edited

I contacted A-P about this.  There's been a last-minute delay, waiting for the official bound manuals from the printer.  I was given the option of immediate shipment of the handset if I wasn't interested in getting the manual, but decided to wait and get the bound Mach2 manual at the same time (I have the early stapled version).

Thanks, I found it. I am expecting to be notified of a shipping date for my mach2 very soon.

Hi Harold

Scroll down through the messages in this (AP-GTO) group and find the message on November 10 from Harley Davidson (a.k.a. Tony). There is a link to his You-Tube video there.

Tony has made several really good videos over the years. They are worth watching.

Got it. I was overthinking it. To all, thank you for all the help. This support site is a lifesaver for laypersons like me.

When I power up tonight, I am unsure what to do
I assume that you are using either APCC or a planetarium program that uses the AP ASCOM driver. Either one, you simply set the initialization to "UNPARK from PARK5". That's all there is to it.

Hi Rolando,

I never did establish a home position. Right now the scope is in park 5. I moved it there using the APCC telescope control buttons. When I power up tonight, I am unsure what to do based on your explanation. Can you give it to me another way so I can understand.

Thank you. Rick.

you should unpark from Park 5 in APCC

That should get you close enough to do a recal

Wrong use of a sync can get your mount lost nicely. Sync should never be used if you don't know where the mount is pointing. The whole idea of sync is to update the present position of the mount to the object that the scope is actually pointing to. If you don't know what object it is pointing to, then doing a sync is both pointless and will indeed get the mount lost. Example: the scope is pointed to Vega, and you bring up Deneb and sync on Deneb. Ok, the mount now says this gear angle represents Deneb, and uses that reference point to slew to other objects. Of course all subsequent objects are off by the RA/DEC difference between Vega and Deneb.

How to recover? You must re-define the mount's gear angles to correspond to the objects that the scope is really pointing to. Since the mount's gear angles are always known, it is a simple matter if you have defined the home position to a specific gear angle (example: Home = Park3). Then to recover from an errant sync, all you need to do is send the mount Home and recal in APCC. Now the mount's gear angles are in sync with where the telescope is pointing.

Hello All,

I've had the AE's installed for 2 weeks now and last night the scope was not pointing at its target. It was off by approx 20 degrees in RA. I tried a plate solve and it failed. I assume I was too far away using the plate solve settings I had. So I did a Sync and that made the mount think it was in a crazy orientation with a negative Dec. I did not want to slew anywhere so I manually slewed back to its park position using the telescope controls in APCC and called it a night.

I never set a home position in the AE tab. If I did, I assume this would have fixed everything.

The scope it at a remote observatory and I can't make manual adjustments any time soon.

Is there a solution for me where that does not involve loosening the cutches and manually moving the scope? Can I delete the coordinates in the CP4 and input the coordinates of my park position? Is there another procedure?

I'm hesitant to start it up and initialize because I am not sure what direction it will move. I do have cams in the observatory and can monitor it and if it starts going in a dangerous direction, I can stop the slew. But right now, I do not want to touch it until I get some expert advise.

I'd appreciate any assist here. Thank you.

Rick Darden.

Could somebody provide a link to the video.


Re: Help! My AP1100AE is lost

Eric, I always park in position 5 and it is there now. I assume I can use that instead of only park position 3?


Re: Help! My AP1100AE is lost

Hi Sébastien,

That threads seems to have relevant info there. Tonight, I'm going to drill down on this and get it fixed. I will try your way (and Eric concurs) and also what is recommended in the thread you linked if I have no luck. Much appreciate you responses.

Use the cameras to move the mount to Park 3, then park at current location, then unpark from Park 3.  That should get you close enough to do a plate solve.
Then set home position in the AE tab.
