Re: Sync without the hand controller

D Sidote <dsidote@...>
 

Rolando,

Thank you for the detailed response. I should mention again that this situation only occurred once, and I have had many successful nights imaging since, without so much as a hiccup. For this reason I am sure I made a mistake somewhere in the process. I will give Howard and see if we can identify where I went wrong.

Thanks!
Dave

You can recalibrate on a star on either side of the meridian, so that is not the issue.
 
Once you have set your mount and scope up, you will never need to do a sync for any reason. The mount servo always knows the two gear angles, and if your software sends the proper time/location at startup, the servo can convert these gear angles to RA/Dec. Then you simply send your mount to an object, center the object via your plate solve (or other means) and do a recalibration (Recal) on this centered position. Recal does not involve the meridian flip point, so you can recal even if the scope has moved past the meridian and is now under the mount.
 
However, if your software sends a Sync command, then it is telling the mount that not only this position is that of the object, but also that this orientation of the scope/counterweight is correct. When you do a Sync and the scope is anywhere past the meridian, even slightly so, then the scope is underneath the mount and you are defining this as the correct orientation of scope/counterweights. All subsequent slews will place the scope underneath the mount (because you have defined the counterweights as the scope and vice versa). Therefore to avoid this, once you have set up your system, and it is permanent, you would never send a Sync command to the mount again, only Rcal after centering the object.
 
If you want to determine why your situation happened, please call Howard here at AP and discuss with him your startup software or procedures, and he can then determine why your scope ends up underneath the mount.
 
One very obvious place where this may occur is when you start up from Park1, start the mount tracking but do not immediately initialize the mount with the time/date/location data. After a few seconds of power on the mount will track past the meridian and the scope will now be underneath the mount. If you now send the startup data when the scope has tracked past the meridian, you will have defined the counterweights as the scope and subsequent slews will send the scope under the mount. For this reason we recommend to NOT place the mount in Park1 position in a remote setup where you are not using the keypad, rather use Park2, 3 or 4 (or any other custom position that is not near the meridian).
 
The use of the keypad prevents this problem because the keypad sends that data the moment power is applied, so you never have the situation where startup data is delayed.

Stuart,

That may be the issue. I usually start imaging in the east, but I had a few hours before the target was high enough to see so I started collecting frames on another target west of the meridian first. I will have to try it the next clear night.

Hi Stuart,

I made that mistake early on when I first got the mount. I now make sure that the time displayed in the APCC status window it correct when I start up.

I think I am just not understanding the process for starting up and the initial sync when not using the hand controller. Everytime SGP does a plate solve its syncs which would be converted to a recal, but what about the initial plate solve? Would that automatically be a sync?

Rolando,
 
    Just to clarify , you wrote ...
... However, if your software sends a Sync command, then it is telling the mount ....etc.
 
    Unless Software Bisques own TSX Driver is being used, surely the ASCOM V2 driver’s box,  set to “Convert Syncs to RCALs”, prevents this from causing a problem.
 
    So, the safe method is to always use the AP ASCOM driver which fortunately,  has this option box set, by default .

Re: Azimuth adjustment?

Good to know. My setup will be permanent so I'll lock them down after setup!


Re: Azimuth adjustment?

Roland Christen
 

These two screws actually act as clutch adjustment for the rotating pier adapter. tighten them, and they lock the pier adapter in place, loosen them and they allow rotation of the pier adapter - azimuth adjuster.
 
If your mount is in a fixed location, you really only do it once, and then you can tighten the two screws and never worry about it again. If you are mobile and set up and tear down a lot, then simply leave them somewhat loose. That way you can adjust the azimuth each time and not have to fight the tightness of these clutch screws.

Hi Bill,

I was waiting with baited breath to see what the 'official' reply was on this. I just set up my own AP1100 a month ago and had the same problem you describe. I was quite afraid of turning them too hard so as not to break anything.

There's nothing clear in the book, oh, there's a short sentence which you have to read very carefully to get the idea, but finally I got proactive about it, and just tried it out (a friend who owns a bigger mount told me never to touch those screws, but it made sense to try it out). Then I wrote to George at Ap to get his blessings. I have a feeling this is a delicate point somewhere at the AP offices, don't know (they know a lot of stuff, don't worry). He was somewhat surprised either of them required adjustment because he said they were adjusted at the factory before shipping. I suspect temperature differences are the cause of the discrepancy, don't know.

Anyway, the cure: There are two recessed allen key screws on the base, have a look, they point inward, you can't miss them, only two. Move one of them in the c/cw position (un-screw) a very very very very little bit until you feel that nice smooth buttery tension they talk about on the azimuth adjusters. Just do one at a time, they both might not need any adjustment, and for heaven sake don't move it one millimetre more than you have to - its bum might fall off.  ;-_)))

Have fun, I hope you enjoy the mount as much as I do. They've done the hobby and the profession a real treat in making something that works as a mount is supposed to work.

I'm new to AP mounts and had a question about a new mount. When trying out the azimuth adjustment, I found the adjusters much harder to turn than expected. This being when they are actually pushing against the center block. They will adjust, but they take a very firm grip to turn. At first I thought they were locked and didn't want to force them, but not finding anything about lock downs in the manual, I tried again with more force, and they do work. But, I wouldn't call them buttery smooth like the altitude adjustment

This being my first day of ownership, I'm not sure if what I'm experiencing is normal, and thought I would ask. I was thing perhaps this adjustment is tight to keep the mount base from being sloppy?

New Image: NGC2264 The Cone Nebula

Steve Reilly
 

Well I’ve been working on this one gathering the data over multiple nights and it isn’t as deep as usual but it seems to process OK. One issue I’ve seen since adding the field flattener is small “ring” halos near bright stars all in the direction of the center of the image. I flipped the filters and took new flats and that really made no difference.  Anyway the image can be seen here: http://www.astral-imaging.com/latest_images.htm with the left image slightly lighter than the right image. Both images are active links to their respective pages that have the image details and links to larger sizes.

 

Thanks for looking.

 

Steve

 


Re: Sync without the hand controller

Hi Carlos,

Did you turn the sync -> recal checkbox back on after the original sync?

I'm not sure CdC sends the location and time, but I think APCC does. I'll have to check the manual.

Thanks!

Re: Sync without the hand controller

Hi Don,

Stuart is trying to help me figure out the issue. I should mention that it only happened once and I didn't change any software settings prior to the slew in the wrong direction. I do have the ASCOM driver set to "resume from last parked" which is always Park position 3. Incorrect initialization if certainly a possibility. I'll check the settings in CdC.

Thanks!

Note: Looking at the date, I think I was wrong about using APCC to initialize the mount. I was still evaluating APCC and didn't want to mess with anything before I finished a mosaic. That means I would have used Pulse guide for initialization.

It sounds like your software is sending the wrong initialization parameters to the mount when you start up causing the mount to think it is pointing somewhere that it is not. If you park the mount in for example, AP park position 3 then shut down, when you start up again, you simply need to have your software that is initializing the mount (AP Ascom V2 driver) tell the mount to "resume from park 3" or "resume from last parked". If you used resume from last parked, It doesn't matter where you park it.
Hope this helps

Re: Azimuth adjustment?

Nice work Bill. I suspect the 'proper adjustment' is the one you just used.

If you're in Florida, it's kinda warm. Near Chicago, well, it's kinda cold. I suspect that's the problem, don't know.

Anyway, we can live with those mysteries, now to enjoy the stars. Always remember:

But, I wouldn't call them buttery smooth like the altitude adjustment


This being my first day of ownership, I'm not sure if what I'm experiencing is normal, and thought I would ask. I was thing perhaps this adjustment is tight to keep the mount base from being sloppy?


Re: Sync without the hand controller

Stuart
It sounds like your software is sending the wrong initialization parameters to the mount when you start up causing the mount to think it is pointing somewhere that it is not. If you park the mount in for example, AP park position 3 then shut down, when you start up again, you simply need to have your software that is initializing the mount (AP Ascom V2 driver) tell the mount to "resume from park 3" or "resume from last parked". If you used resume from last parked, It doesn't matter where you park it.
Hope this helps

Dave, I believe you must always initialize on a star East of the meridian. Could that be it?

Hi Stuart,

I made that mistake early on when I first got the mount. I now make sure that the time displayed in the APCC status window it correct when I start up.

I think I am just not understanding the process for starting up and the initial sync when not using the hand controller. Everytime SGP does a plate solve its syncs which would be converted to a recal, but what about the initial plate solve? Would that automatically be a sync?

The other night I tried to slew my mount to my imaging target and the mount unexpectedly went the wrong way. Nothing happened as I was there to stop the slew, but I would like to understand why. The date, time, lat/long were all correct. I assume its an issue with syncing.

My mount is permanently setup and polar aligned, so all I have to do it mount the telescope and plug in the computer to be ready for imaging. I use sequence generator pro to automate everything along with phd for autoguiding, and Cartes du ciel for planetarium. I do not use the hand controller.

This is my workflow:

1. Start up APCC, and initialize the mount
2. Connect SGP, Phd, CdC
3. slew to the object in CdC
4. Plate solve in SGP (which performs a sync) to frame the object (I have sync -> recal checked in ASCOM driver)
5. Start taking images
...

6. finish taking images
7. park the mount
8. disconnect CdC, Phd, SGP
9. close APCC
10. power off

so...

Do I need to uncheck the sync -> recal for the initial sync or is the first rcal automatically a sync?

How does one clear a sync and start over?

I did search the yahoo group and the manuals but couldn't find the answers.

Thanks!

Re: APCC JNow/J2000

Brian Hitney
 

My understanding is that SGP assumes plate solvers will be j2000.  Yes, it will convert those coords as needed to jnow, but if astrometry.net is set to jnow, you'll have a problem... You didn't say if you are using astrometry.net, but check that setting if so.

Stuart,

That may be the issue. I usually start imaging in the east, but I had a few hours before the target was high enough to see so I started collecting frames on another target west of the meridian first. I will have to try it the next clear night.
