Re: HELP! Mount is lost - how to recover

Stephen Winston
 

If you are remote, what it the recommended recovery?

Would the following work: 
- Power cycle mount, move scope to star on opposite side of mount, SYNC and carry on?
Or maybe:
- Move mount to known park position, power cycle mount, resume from park, slew to star and RCAL




HELP! Mount is lost - how to recover

Roland Christen
 

Hi Astronuts,

If you ever do an errant sync with the counterweights above the scope and subsequent slews try to run the scope into the pier, DON'T PANIC. There is a simple easy way to recover.

Simply loosen the clutches on both axes, hold onto the scope and send the mount to Park3. Once the motors have stopped turning, simply place the scope manually in the Park3 position, tighten the clutches and proceed on your way as if nothing had happened. Your next slew might be off a bit, depending on how accurate you set the park position, but you can then center the object via the buttons and press Recal. Now you are fully calibrated again.

Note: you didn't have to cycle power or do any gymnastics (stand on your head and clap 3 times) or anything else fancy or confusing.

In that regard, I agree that the AP V2 driver documentation and user feedback should be more clear. The only place that you can
change Lat/Long is in the AP V2 setup dialog, which is usually run when the driver is not connected. And in the help section for
"Initialization Setup" it states that most of the options (including "Set Latitude/Longitude") apply only when the mount is
initialized. I think a more straight forward statement there is needed.

https://www.siriusimaging.com/apdriver/help/initialization_setup.htm
Yeah it essentially says that, but it could be clearer for sure.

However your thought about applying Lat/Long from a "known" parked position may be possible. I will talk this over with Howard to
see if there is a "safe" way that this can be done.
If you two could make that happen, it would certainly push me (at least) over the edge on making the CP3 (Rev O) -> CP4 jump. Due to living under a light dome and having poor sight lines to the sky around my house, I'm stuck having to be mobile for any viewing/imaging except for solar. Between the different club sites or places I go camping, any improvement in flexibility and ease regarding Location setup would be a big deal.

The subject must have released the gremlins, as just this past weekend I spent an hour trying to figure out a location issue that my CP3/Mach1 started experiencing after I had to switch batteries, which of course meant the mount had to be powered down momentarily. When I brought the CP3 back online with the new battery, the driver could not change the lat/long *at all* and the mount was stuck at 0/0 for its lat/long:

http://i.imgur.com/eKA8Xqd.png

After an hour of repeatedly power-cylcing the CP3 and trying to get the driver to initialize the it with the right lat/long for my site's preset, the problem persisted. Eventually, I gave up and dug out the hand controller, inputted the site's lat/long into a location slot and was able to set it that way.

Thanks again for the feedback, Dale!
Thank you for looking into this!

Re: Fist session with Mach1

Ray

APCC worked for a while, then I just had no end of trouble. It was not running how I expected. So I decided to reinstall following your instructions.  I am pleased to say it is now working. Again.  And probably better.

I have changed some of the settings you suggested back to the way they are in the manual to include the auto initialisation.

Now it is working how I expected it would.

Thanks very much.
Darrell


Re: Can I bring the CP4 into the house

Thankfully I did not attempt to bring the CP4 into the house and I have Horizons working properly with the Ephemeris data from JPL.


My observatory can't be built soon enough.

Of course Roland is correct!
 
Just don't move controllers BETWEEN mounts and run the motors, or the PEM curves will be either wrong or out of sync.

If you stop tracking before shutting down and make sure tracking is stopped for the entire indoor session and is stopped until the motors are reconnected, you won't lose your PEM tracking synchronization with the RA worm drive assembly. Otherwise you will have to rebuild your PEM curve.

At close to 6 hours now. The AP1100 has performed remarkably well. Last two sessions I was around 0.3-0.4" RMS guiding, using PEM Pro 3 for polar alignment. More to come when the OIII data kicks off.

Hello all,


Wanted to share a project I finally have in flight. I swear troubleshooting (things unrelated to my mount) this summer has been such a time sink for me. Anyhow, here is the current state of the data:


https://www.astrobin.com/full/358717/0/


Only 2 hours of HA data at this point. This was taken with a Tak TOA130 with its 0.7x reducer on it and a KAF16200-based QHY16200A camera. The lady is a fan of butterflies so, I figured I would get to working on this. Individual subs came out  very good at about 1.5px or roughly 2.5". Stars were about 0.4 eccentricity. the mount I used for this was the AP1100 using APCC Pro, but no pointing model (as APPM continually failed to solve even at the Zenith via Image Link, for some reason, and ANSVR/SGP takes way too long). I did use PEMPro to dial in the polar alignment though. Guiding in PHD2 was good at about 0.5" most of the night with some fluctuations. I used 3 second guide exposures and the minmo on the two axis was roughly set to about .45".  SGP was the capture software, and as always worked wonderfully (other than focus taking way too long).


Feel free to have a look. Hopefully the weather continues to stay nice so I can hammer away at the rest of the data. In the end it should be a SHO integration, which will look lovely. Maybe tonight I can get Image Link and APPM to play nicely. 😊


Take care and clear skies!


Bill

Re: Finally an image to share

The QHY16200 camera is very nice, provided you use ASCOM with it. The x2 SkyX driver crashes, and INDI driver also just hangs up and never responds after a single frame. On ASCOM though, you cannot beat the sensor size to cost of this unit. OAG, camera, and filter wheel for around $4k. The filters of course will hurt in terms of your wallet, but the price to performance is outstanding IMO.

Hello all,



Wanted to share a
project I finally have in flight. I swear troubleshooting
(things unrelated to my mount) this summer has been such a
time sink for me. Anyhow, here is the current state of the
data:



https://www.astrobin.com/full/358717/0/



Only 2 hours of HA
data at this point. This was taken with a Tak TOA130 with
its 0.7x reducer on it and a KAF16200-based QHY16200A
camera. The lady is a fan of butterflies so, I figured I
would get to working on this.
Individual subs came out  very good at about 1.5px or
roughly 2.5". Stars were about 0.4 eccentricity. the
mount I used for this was the AP1100 using APCC Pro, but no
pointing model (as APPM continually failed to solve even at
the Zenith via Image Link, for
some reason, and ANSVR/SGP takes way too long). I did use
PEMPro to dial in the polar alignment though. Guiding in
PHD2 was good at about 0.5" most of the night with some
fluctuations. I used 3 second guide exposures and the minmo
on the two axis was roughly
set to about .45".  SGP was the capture software, and
as always worked wonderfully (other than focus taking way
too long).



Feel free to have a
look. Hopefully the weather continues to stay nice so I can
hammer away at the rest of the data. In the end it should be
a SHO integration, which will look lovely. Maybe tonight I
can get Image Link
and APPM to play nicely. 😊



Take care and clear
skies!



Bill

Re: First light with Mach1 - a query

Paul
 

Thanks guys. Your guiding seems better than mine but early days yet😊


Re: First light with Mach1 - a query

Eric Dreher
 

I use a similar procedure with my Mach1. Two nights ago seeing was pretty good with RMS at 0.31” and dips into the high 0.2x” range.

I experimented a bit with PEM on and off, with a difference so slight it almost wasn’t worth the bother. My native PE without correction is 3.15” pk-pk. Just a fantastic mount.


Re: First light with Mach1 - a query

Ron Kramer
 

Paul, try a blind/sync in SGP first.  (well polar align first) then move off the pole a ways and do a blind/sync.  This is usually much faster than the local plate solve search. This will sync the mount properly and then a plate solve using your local database will then be much faster.  From then on you can just do SGP - slew and center using platesolve2.  works GREAT for me, but after I mess with clutches or release the worm for balance - I then need to do another blind/sync to get back to normal.  Then plate solves and centering in SGP is pretty quick and extremely accurate. My targets always appear dead center.  Latley I've been getting .3x rms average with a 6" refractor and a 80mm refractor side by side.  I sometimes see .25 and sometimes .45 but 90% of the time I'm in the 0.3x range.  I love my Mach1 too.

In my experience, that error usually indicates that something has gone awry.

In APCC's Advanced Settings dialog there is an option called "Prevent Errant RECALs". Disabling that option will eliminate the 5 degree limit. However, I recommend that you enable the option again afterwards to prevent any potentially bad plate solves from recalibrating the mount to the wrong position.
