Hello all.

I seem to have developed a problem with my keypad. 
AP 1200 GOTOCP2 rev E running Keypad v4.17 
Strange because I was performing keypad GOTOs between Jupiter, Saturn and Mars and putting them all in a 5mm eyepiece field (152mm F8 APO) .
I normally use TheSky for all of my pointing which works fine but I wasn't using it last night.
If I use the Keypad I get weird GOTO results, e.g. GOTO M15 yields "below horizon", when in actuality it was almost at zenith at the time.
Plus the Keypad displays zero or blank object info.
I did change the Keypad battery a few months ago and was not aware that it was supposed to be powered up during the change.
Did I clobber the database and is there a way to recover?
Thanks for any help.

Who sells Thum?  I can't find it on the web.  I, in fact, have a weather station that provides data (ultimately) to the NWS.  It vexes me that I can't use that data for the model.

Ray, 

Can APCC receive temp & humidity readings from Pegasus power/usb box? Wondering what devices can feed APCC environmental readings. Mbox, THUM, others?

thanks,

Re: PHD2 Dec tracking goes runaway after Meridian Flip with Mach1

That is quite possible... (making it harder than it needs to be)

After I hit the problem the first time - I went and unchecked the "Reverse Dec" box... and restarted guiding - but it ran away again.

But that was AFTER the Meridian flip, so I suppose that's closing the door after the cow has left the barn... flip had occurred, PHD2 had reveresed Dec calibration, and unchecking that box would only help the NEXT time...

I will be quite now until I can test this out next clear night (which doesn't look like this week)...

Thanks again!

The ASCOM driver doesn't have a setting for reversing the Dec on pier flip. I don't think that is part of the ASCOM platform.

Well... doing a bit more searching on the board, I have found several posts here that do indicate the "Reverse Dec" box should NOT be checked - including

So now you have convinced me - so - can somebody tell me what the configuration settings SHOULD be for the AP ASCOM V2 driver and PHD2 in order for this to work?  
I can experiment - but I'd sure rather image than experiment :-)

Disable "reverse Dec output after meridian flip" in PHD. that's what it *should* be

You might be making this more difficult than it is ;)

I don't think your friend is necessarily wrong - the first thing you need to do is uncheck it and see if that in fact does work.


There may be a number of other variables at play in a difference between yours and his - configuration settings in ASCOM, in PHD, version of PHD (1 or 2?), your firmware version, etc.

Roland Christen
 

I use MaximDL and I check the reverse on flip box. Maxim DL works thru the Ascom driver and thus knows when the mount is flipped to the other side. Therefore Maxim will actively change the guide commands accordingly. I don't know how PHD2 does things.

Roland - can you answer definitively:  does the "Reverse Dec output after meridian flip" need to be checked or not checked?

I ask that because over on the PHD2 board, I have a guy telling me " The ASCOM driver for A-P mounts knows the 'side of pier' for the mount; so there is no need to check the reverse Dec box n PHD2"

And I have Michael Fulbright - a good friend and long time Mach1 owner telling me "if you uncheck the reverse dec box it will certainly not work"... 

I'd put my money on Michael - but this is why I have come to the experts.

IF the box DOES need to be checked - are there any OTHER settings that I need in the AP ASCOM driver?

Third confirmation of Brian and Steve's advice, the "Reverse Dec output after meridian flip" should be UN-Checked. I imaged over the weekend with an automated meridian flip in SGP and had successful guiding on both sides of meridian before/after (mostly at least, darn wind). 


Re: Mach2 model building and pointing with Sequence Generator Pro

Ray Gralak
 

Steve,

Let me ask you and Ray, is it required to have current weather conditions always while running APPM for tracking
corrections of the AE to function well on the mach2? If so, that is a current problem for me as I do not always
have web connection where I image, nor a weather monitoring device. I suppose I could pick something up for
weather monitoring if anybody has a suggestion.
For the most accurate tracking rate correction, precise temperature, pressure, and humidity values should be supplied to the mount.

The most important value is the temperature, followed by the pressure value. Humidity has less of an effect.

If you don't have a weather input device, such as a THUM or MGBox V2, then you can manually enter the values on APCC's Pointing model tab. If you have an internet connection and there is an OpenWeather device near to you, you can use the ASCOM OpenWeather ObservingConditions driver to get temperature, pressure, and humidity from the OpenWeather device.

Re: Mach2 model building and pointing with Sequence Generator Pro

Ray Gralak
 

Steve,

Thanks for responding the for the suggestions. I have not used user profiles in the past, so that may be the SGP
issue. I will set one up. I do have the coordinates stored in the AP v2 ASCOM driver, using ASCOM platform 6.4
SP1 6.4.1.2695.
Okay, that's good. What kind of telescope are you using?

One thing I am wondering is, how does the mount ever get synchronized to the sky?
Using APPM is the most accurate way to synchronize the mount to the sky. As part of capturing sky data, APPM will synchronize the mount to the sky (a "RECAL").

Later, after a model is in use, the mount can be recalibrated using an ASCOM sync, but that assumes the calling program has accurately converted a plate solve's J2000 coordinates into the current epoch, and is accounting for refraction. Alternatively, using APPM's run tab is likely more accurate. APPM's "Run" tab, there are buttons that allow you to plate solve and/or RECAL the mount. The use of plate solving in APPM assumes it has been set up in APPM.

Can you also let me know where are the APPC logs stored?
You can use the APCC Log Zipper to find logs and to create a zipped file of the appropriate logs. You can run the Log Zipper utility from APCC's Tools menu.

Providing a dropbox link to the zipped set of the logs might be helpful. Please remember to indicate the calendar date and time, so we will know where to start looking in the log files.

This is meant for Ray Gralak. With the new mach2 being controlled by SGP version 3.2.0.613 and APCC/APPM
latest version I have had two opportunities to test.

It may well be I am doing something incorrectly in the process. Let me preface this with my old mach1 could use
SGP plate solve and sync, then pointing with coordinates with very accurate pointing results. I have carefully
checked any parameters set for the OTA and camera. Since plate solves are passing, I'm assuming the required
parameters are correct.

With the new mach2, here is the process I've been following:
1) Starting up, doing what I consider a good polar alignment with Sharpcap (3.2), then connecting with SGP.
2) Do a solve and sync with ASTAP (also tried platesolve2 with no difference in results) which is successful.
3) Try to slew to a target, e.g. Vega. The slew ends up with the target somewhere off in a corner or not even in the
field of view (~32' x 22').
4) OK, not totally unusual so then use the "center target" which is plate solve based which always worked in the
past. This moves the target somewhere ~ 10 arc min to the left of center and happily reports centering success.

Let me further explain, I have attempted this two ways.
1) No APCC/APPM run, just the steps above.
2) Use the APCC/APPM flow as I read it, I did setup horizon limit before starting.
a) power up, connect to APCC, park the mount at park 3, which always works!
b) try the homing under the AE tab
c) Run APPM to generate a sky model. So far have tried the small and medium models. All points plate solve
successfully.

After the model run, I make sure both items below are selected:
Enable Pointing Correction
Enable Tracking Correction

When I try with either method 1 or 2 with or without model, the slow to object still has a large offset.

One thing I am wondering is, how does the mount ever get synchronized to the sky? The plate solve and sync in
SGP does not appear to be working. Does the model making process automatically sync the mount to the sky?

Can you also let me know where are the APPC logs stored?

thanks,
Steve


Re: Mach2 model building and pointing with Sequence Generator Pro

Marcelo Figueroa
 

I am far from being an expert, but I believe that since you are a mobile user, you necessarily have to build a new model every time you setup your equipment. So probably the updated weather information is not that important, unless you want to do very long exposures (10 minutes or more I think). In that case you can continue to use guiding with this technique of Roland: Nudge Guiding
 
In my case my installation is permanent in my backyard, I use the same model every night, so updated weather information is vital.

Re: Mach2 model building and pointing with Sequence Generator Pro

eckhard.voelcker@...
 

Hi Steve,

I am using a similar workflow with the Mach2:

1) Power On, Start APCC, Start Sharpcap, Start SGP. Connect equipment (Sharpcap to the main camera, SGP without the camera)
2) Polar Align with Sharpcap, close Sharpcap, connect camera in SGP
3) Start PEMPro, connect to mount and to SGP. Slew to point in sky for azimuth measurement. Measure azimuth drift, correct and repeat. Slew to point in the sky for altitude measurement. Measure altitude, correct and repeat. Quit PEMPro.
4) Slew to traget in SGP. Platesolve (Pinpoint, licensed version).
5) Start APMM. APMM shows me where the telescope is pointing at so it is easy to set points along the path of my target moving West. I use a corridor of 3 points with the targets path more or less in the middle. APMM builds this model in approximately 10 minutes.
6) Enable the model, center target in SGP.
7) Adjust focus and start imaging.

Some comments:

Platesolving close to the pole is unreliable. Better move somewhere else first and then plate solve. Afterwards entering with SGP is dead on!
Since I switched to the Mach2 I don't guide anymore.
My polar alignment improves considerably when I run PEMPro after Sharpcap!
Building a model is surprisingly easy and fun.

I have had zero problems with the Mach2 using this workflow.

Hi Ray,

Thanks or responding. I am using ASCOM 6.4 SP1-6.4.1.2695. There were a couple suggestions already given that may help with SGP. I don't have a local environmental monitor. How important is that for accurate modeling. In addition, sometimes I do not have a web connection where I image at. Primarily I am mobile, no observatory.

Re: Mach2 model building and pointing with Sequence Generator Pro

Steve Armen
 

Thank you for responding Marcelo.

Yes, your flow sounds very similar to what I have tried with APCC with the Mach2. I have not used it in the past. In addition, I want to use CdC for planetarium ultimately to drive the mount around, that would be fantastic if I can get it to work!

I have used Frame & Mosaic Wizard in the past. It works very well as a planning tool. Let me ask, do you have a user profile setup for SGP. I never took that step or  read that was necessary for pointing to work. It just always worked for me in the past. Maybe with a more recent release of SGP, that changed? 

I will look at the weather information site to use with APPM.
