Suggestion for remote operation: sometimes we lose communication with a remote
mount. It would be nice to have a feature that stopped tracking at a certain limit past
the meridian.
If you are running APCC it can be setup to stop tracking when a limit is reached. The limit can even be different for each declination so you can prevent collisions in all cases.

The Rev V firmware also has a dead-man timer function that APCC uses. If APCC stops, the serial cable removed, or if even the entire PC crashes, the mount will automatically stop tracking after a short user-configurable timeout.

However, I can not seem to get this thing to flip at the meridian.
Conducted two tests, One using SGP with the pier flip option checked.
No joy. I also remember the other night I was on M51 and got the msg from
SGP that the mount failed to flip.

One using just the mount tracking an object through the meridian, and that is

The Keypad delay is set to 0.
Do I need to put a value in here to activate the flip?

I am using what I assume to be the latest Ascom driver V2 from the link on the

Any ideas?

That sounds difficult. How will the mount know that it's supposed to stop tracking? Sounds like a firmware change in the mount's controller and send a new command (from PC or hand controller) to the mount to give the mount's permission to stop tracking according to your requirement.

Re: Mach One pier flip

sarnoskypeter@...
 

Well I was actually running the sequence when I got the msg from SGP that the flip failed.

I think I was still doing my lights.

I had auto meridian flip selected (at 0) with center after flip.

It did not.


seems odd to me that the keypad lets you select how far before or after to flip as SGP does, but will not do it un commanded.

While conducting my test yesterday, it tracked through the Meridian but did flip after I initiated another goto from the handset on the same target.


Re: Mach One pier flip

Roland Christen
 

Yes, we have that feature. It's called limits and can be done either with the mechanical limit switches or with the absolute encoders if the mount has that option.
 
We have the Chile mount with the encoder limits set to stop the mount tracking approximately 1/2 hour past the meridian. It has saved the mount several times when we had computer failures. The limits work even when no external commands are possible due to communication failure because they are embedded in the mount and don't require any outside signals.

Re: Mach One pier flip

topboxman
 

For a successful SGP Meridian Flip, I believe it requires that the Sequence must be running which includes imaging and possibly plate solving if "auto centering after Meridian Flip" is enabled. If you simply connect SGP with the mount and have Meridian Flip check box checked and did not initiate a sequence run, then SGP will do nothing.

I am just assuming that's what you may have done. Please provide more information on how you set up SGP and whether you clicked on "Run Sequence".

The only value needed is how many degrees past the Meridian before SGP initiates a new GoTo of the same object. This value is default to 0. I like to put 1 or 2 degrees only if the scope does not collide with the pier.

Re: Mach One pier flip

Stuart Heggie <stuart.j.heggie@...>
 

Peter, my memory on this isn't the most current but it seems to me that you must issue a goto command to trigger the flip. My AP900GTO (older in every respect) will happily track through the meridian unless I issue a goto. I love this feature since for some targets and some scopes, you can image dusk to dawn, through the meridian, without worry about anything colliding. No flip, not reacquisition of a guidestar etc.

Re: Looking for recommendations for Astronomy friendly RV campgrounds

Woody Schlom <woody@...>
 

Ron,

 

There’s a State park in New Mexico named “City of Rocks State Park” that’s an astronomical park.  In fact, all or most of the campsites have both a number and a celestial name.  This park also has a permanent observatory and puts on regularly scheduled star-parties.  I’ve only passed through it, but as I recall, they do have a partial hookup area in the front.  But the really nice sites are all dry.

 

Also, many of the Arizona State Parks host star-parties and probably turn off all their lights on those weekends.  AZ State Parks posts their star-party schedule online.

 

My experiences with several of the more remote AZ State Parks has also been that aside from restroom lights, many have no lights on at night at all – or at most a couple of very well shielded down-lights.  So if you get a campsite that’s out-of-sight from the restroom lights, you’re good to go.  And most AZ State Parks have partial hookups.

This may be slightly off-topic but I am looking for Astronomy friendly RV campground recommendations in Arizona, New Mexico, or Texas. I live in Northern Colorado and want to spend a few months this coming Late Fall/early Winter taking astro photos with my AP Mach1/Celestron C-11 HD. I would like a commercial campground that has at least power and water in a setting that does not have a lot of interfering lights and is in an area that does not normally get extremely cold. Recommendation would be greatly appreciated.

Thanks in advance.

1)      Although this isn’t exactly what you’re asking for, “Butterfield RV Park and Observatory” in Benson, AZ has its own observatory with a 16” Meade.  The management puts on shows for the RV park customers.  Customers are NOT permitted to operate the scope themselves.

2)      Some RV parks have special “lights out” weekends for astronomers.  For example, “Palm Canyon RV Resort” in Borrego Springs, CA (an official dark-sky town), turns all its lights out on certain New Moon weekends in cooperation with the RAS (Riverside Astronomical Society).
