One of my personal rules is that I never recalibrate or sync any GOTO mount on solar system objects. The orbital calcs are always complex and positional errors are the rule, not the exception.

Hi Bruce,

Unfortunately, SkySafari has limited choices for initiating and unparking.  You would need to reset your park 4 position each new session unless you didn’t re-align during the prior one.  One thing you could try is to realign on a star near the park 4 position before you shut down.  That would be low in the southern sky.  That should at least get the next startup closer.

All sky positions are calculated from the previous object that you did a Recal on. That includes park positions. If the last object that you Recal on is off by 1 degree when you pressed Recal, then every object that you go to including all park positions will also have that 1 degree error.

Your errant Recal could be the result of an error on your part or deliberate if you wanted to center a nebulous object and then did a recal on it. What you might think was the center might not be the center as defined in the database, so that throws off everything else following that move.

We are working on changing the way parks are generated so that they are not affected by errant recals or syncs. The software will be available for the CP4 and will be standard in the Mach2 CP5 controllers.

PEMProV3 error message

Ted Mickle
 

Ray,

I've used PEMProV3 from with APCC Pro in the past without difficulty but now am encountering an error message when attempting to access the CCDWare website, check for updates, etc from within APCC Pro/PEMProV3:

   "Unable to open browser: access to path "C:\Users\Documents\CCDWare\PEMProV3\temp.htm" is denied

Also, when I attempt to acquire data, set the image scale, etc, I encounter this error message:

   "Failure to write mount definitions: Access to path is denied"

My guess is that a configuration has changed somewhere in Windows 10 -- any suggestions to remedy are welcome.

Thanks,

Ted

Hi Ray

Sorry- what I meant by manual was re-aligning using SkySafari and not un-clutch it. Thanks for the follow-up and the other possible reasons for this. I just wanted to confirm that I was not doing anything obviously wrong.

Hi Bruce,

If you mean that you manually un-clutch and center a target, then yes, that can cause the park position to be offset a little. This is nothing to worry about though. It doesn't mean there is anything wrong with your mount or setup. A pointing offset can be caused by a number things including polar alignment error, non-perpendicularity of the optical axis, flexure, refraction, etc.

Almost 100% no slippage. Everything tight and well balanced before beginning a session.

I do manually realign to center some objects at times but that is it. Could that be the cause? However, I have not
noticed any consistent pattern or trend.

A couple things come to mind:

1. Are you sure the clutches are not slipping?
2. Were any RECALs performed, either manually or via plate solves? They can slightly change the effective
mechanical position of the park positions.

Hello ,
      I’m using version 5.20.09 . I tried a new software called Astrophotography tool ie APT . It connects to ascom camera and focusser but not mount . I’ve informed the vendor . Any idea what else I should do ?
Thanks

In com 3 I get : no mount found , at the same time works with phd etc
Make sure none of your applications is running "as administrator". This will start another separate instance of the ASCOM driver which won't be able to connect if the first instance is already connected.

I use APT and it works with both my Mach1GTO and AP1100AE. No problems whatsoever. What do you
mean it doesn't connect to the mount? Does APT see the AP ASCOM driver?

Re: APPM Remove Scope Question

Ray Gralak
 

I have a permanent pier and scope setup using a AP1100 Mount and AP130mm scope. My question is, if I remove
my scope from the rings and then replace it again will my pointing model still be accurate? Will the slight movement
from the rings felt ruin my model?
I do this all the time. If you place the scope back in about the same position the model will work well from night to night.

Bryan,

Is there information somewhere that provides guidance on good/fair/poor values for Pointing Correction Status and
Tracking Correction Status, as well as the other values in the ApModel window, e.g. Tube Flexure?
There are no good/bad values per se. All of the terms are in arc-seconds. What is more important is how well pointing terms as a whole model the telescope setup and how consistent pointing is. For instance, if the scope's rings, or adapter from scope to camera, have some play then there might be some randomness in pointing accuracy as well as some additional error in the model itself.

Re: Ascom problem

Cheng-Yang Tan
 

That is very strange ... AP ASCOM driver allows multiple programs to talk to it. I have PHD2, Cartes du Ciel and APT talking to the AP ASCOM driver. Are you sure you have set APT to talk to AP ASCOM?

Which program says that "no mount found in com3"? It sounds like it is from AP ASCOM. If that's the case, then you have not set up AP ASCOM correctly.

I have done a number of such changes back and forth with different tube assemblies even. The pointing does not seem to be affected. Not to any degree that i can tell.
