There's no special version for this. I'll have to look into this.  But, I will need you to confirm your firmware and software versions (above).

Re: How to prevent small movements

Roland Christen
 

If the small move is made as a timed move, the mount will move directly to the new position. This would be the proper way to send small dither commands to the mount, unfortunately not all programs will do this.

If the move is made as a co-ordinate move (GoTo move) then the mount will do a 2 step move, one step out of the CWT up and then a final move into the CWT up. This is called a safe slew.

Since we have no control over your 3rd party dither move, it may be that it is sending a coordinate move and the mount must follow the safe slew routine. I know that is a problem with MaximDL, which sends a new coordinate to the mount even for a simple 5 arc second move. It would have been more robust and logical for them to send a short timed move for small move commands. They do this for guide moves, but unfortunately not for dither. This is also a problem for the mount because when a new coordinate is sent, the mount no longer has the original object's coordinate in memory, so it makes recals no longer as accurate.

APCC has no part in any of this because all it can do is to pass along the commands that are generated by your 3rd party guider program. If they use coordinate moves, then you will get safe slew moves.

Re: CCDWare site Trojan?

Joe Zeglinski
 

I agree,
    The two antivirus programs are independent, but Defender hasn’t changed much in many years, so it is just  testing its new features now. Consider it a trigger happy Beta for a couple of its next few updates, until the kids at Microsoft have us all test the rewrite for them. If it continues to get in the way at CCDWARE, change Defenders sensitivity for that website, in its new settings options. If Malwarebytes didn’t flag it, in its own Reports, then the only other app may be Defender, unless you have even more A/V’s active.
 
    Perhaps the only reason I still keep Defender active is for its Win-10 “pre-boot” virus scan user  option, which MB doesn’t seem to have.

CCDWare recently (last week) moved to a completely new site, so maybe refreshing your browser will help?

The site will look similar but was completely rewritten well after February.

Re: CCDWare site Trojan?

Joe Zeglinski
 

Hi George,
 
    By any chance are you now running with the Build 2004 Update of Win-10?
 
    Microsoft ... “drastically changed” its DEFENDER antivirus program in this recent major update  -  and added new features to it.
One of these is that it reports and even isolates PUP’s (potentially unwanted programs) into its own Quarantine, which you can undo, just as with MB’s A/V. You can see which ones got blocked by going into Settings and looking at Security/Defender. There is a list of blocked PUP’s it was responsible for – nothing to do with Malwarebytes.
 
    Also, perhaps the good news is that DEFENDER used to “bow out” if another antivirus program was found in the system. But if you chose to change the MB setting to NOT register itself in Windows, then BOTH antivirus programs would always be running. Then you will get DEFENDER interfering with its own opinions about PUP’s. I would trust MB over it now, since this is totally a new way of doing things for the revised Defender (darned nuisance).
Beginning to think that Build 2004’s DEFENDER is actually the  “Potentially Unwanted Program”.
 
    Among those it now doesn’t like, for example,  was the PIRIFORM’s  CCLEAN which has been just fine for over 10 years, and now Defender just got uppity about it. Meanwhile, my latest MALWAREBYTES is fine with it, always has been, never reported it as even suspicious. Likewise, changes in the communications area logs me out of my email account every 24 hours or so, even if the PC never hibernates, something new on three PC’s I know of – another build 2004 oddity. Too late to roll back to Build 1909, which was much more reliable.
 
    I suspect, if this is what you are running as well, it was Defender not Malwarebytes blocking  PEMPRO access.
The good news is that Update 2004 will go away by November to make space for the next major Microsoft Win-10  screw up.

Re: Help With APPM and Dome Slewing/Camera Image Not In Sync

Ray Gralak
 

Hi Tony,

 

You have several options you can try:

 

1) You can use an intermediate ASCOM dome driver like "ASCOM Dome Control", that APPM can poll to determine if the slew has completed. If you do this, configure the dome control method in APPM to use the passive method as shown in this screenshot:

 

 

2) On APPM's Measurement Points tab, you can select "Hour Angle" as the Point Ordering Strategy.  This will minimize the required dome movements.

 

3) On APPM's Run tab, you can enable the checkbox "Pause after Each Slew," which will allow the dome time to finish a move. The drawback is that you will have to manually continue after each point.

Hi George,

As Brian stated, PEMPro does not have a Trojan virus. You probably clicked the download button for CCD Navigator or Weather Ninja, which for some reason, sometimes gets a false positive.

I asked John Smith to move the other application's download link away from PEMPro so that hopefully, others won't click the wrong link by mistake!

Subject: [ap-gto] How to prevent small movements

Hi Ray,

I forgott how to prevent small movements in the cw up area, if the mount is taking small movements for dithering.

Re: Delrin plugs

Joe Zeglinski
 

Michael,
 
    AP sells DELRIN Clutch plugs  as a kit – and I suggest getting spares  just in case you lose one, or have a problem fitting it in. However, You will need AP’s  simple but  special tool -  and fair warning,  it is still a bear to use successfully.
 
    Lesson I learned with those DELRIN clutch plugs – “Finger tight” knobs, may STILL  be too tight, so you get mushroomed plugs, very difficult to extract. Wouldn’t want to have to do that ever again, and really admire the AP staff,  if they have to do this repair.
Good luck.
 
Joe Z.

Hello – I have a 900GTO mount bought new in 2011. I think the Delrin plugs have gotten compressed; I notice that when I am balancing my setup, they barely move. Probably too enthusiastic when tightening down the clutches.

 

I looked on the Astro-Physics site, but couldn’t find them. Does anyone know where to get a set of replacements?

Re: CCDWare site Trojan?

I downloaded PEMPro 3 from CCDWare about a week ago, and I haven't seen any problems with Trojan horses.

Ah, OK, not a big user of PI but the chart helps.  Thanks...

Hi Mike

 

I think you may be thinking of star flatness?

 

i snagged this description out of PI's subframe selector - btw in this doc they spec 0.42 as being perfectly round

 

Eccentricity is a measure of star profile distortion. Given an elliptical star profile with major axis diameter a and minor axis diameter b where a is greater than or equal to b, the star profile eccentricity equals (1 - b2 / a2)0.5, the star profile aspect ratio equals b / a and the star profile flatness equals a / b - 1. For all stars fit in an image, their Eccentricity is weighted by the StarResidual value to minimize the influence of bad fits. A distortion with an eccentricity less than about 0.42 is not perceptible to most people. The table below shows the relationship between these measures.

The value of .5 is stated as round, I am curious if .05 is what people mean.  According the Maxim's help, a value of .1 means that the star is longer in one axis by 10%, so a value of .5 would be 50%.  That would be horribly out of round.  Want to make sure that I am following.  With my system, PW 17/AP1600 (non AE)/STL6303E camera/Optec Gemini rotating focuser/.63" pixel/5' subs I generally get roundness values from .01 to .05, depending on where the system is pointed/seeing.

>>>  Is the solution a Planewave?? J

 

  either that, or I hear AP has a 17" reflector they are working on :)

 

>>What should I expect for good eccentricity - .35ish??

 

generally eccentricity of 0.5 or lower is considered 'perceptibly round'

 

I'm not sure i would 'expect' that, but i would certainly aim for that

Thanks Brian. I’m sure mirror flop is a definite possibility, even with the Edge mirror being “locked down”. Is the solution a Planewave?? J

Okay thanks

 

I'm poking around in your logs some, and I'm waiting to hear back from someone else I asked a Q about, but I can see your RA corrections are primarily one-sided at higher altitudes (and a corresponding increase in RA and therefore your eccentricity goes up), and as you get lower in the sky, RA corrections become more even on both sides, and your RA RMS and eccentricity both go down

 

My suspicion is mirror flop or something shifting in your equipment
