Re: Issues with Windows 10 Build 1709

I started this hobby at least 5 years ago using Windows XP and then upgraded to Windows Vista, 7, 8.1 and 10 and never once I had issues with any of my astro gears. I don't recall having any crashes or failures. The only failures I had were operator errors. Sorry you had issues with Windows. I have read several horror stories about Mac OS especially El Capitan that broke Software-Bisque TheSkyX big time so Windows is not the only OS that had reported issues.

Re: Gold plating thickness on connectors

Christopher Erickson
 

I would say that quite often what we get today is Chinese stuff that LOOKS
like gold but isn't. Usually its a bright yellow blend of brass, copper,
zinc, silver and other stuff.

And even with actual gold, 24k is too soft to be useful in many applications
and what is actually used is often 10k gold.

Bell Telephone's "Registered Jack" (RJ) modular snap connectors are not a
very good connector overall but they are incredibly-cheap to use in
manufacturing.

Given your humid, salty environment I would suggest implementing a marine
electronics practice and add a tiny amount of dielectric or silicon grease
to your connectors (AFTER carefully cleaning them first) to block any
airborne corrosive elements from getting to your metal contacts.

A local dive shop (or eBay) would be a good place to obtain some nice, thick
O-ring silicon grease.

All you need is enough to coat the contacts and keep air from them. More is
usually just messier, not better.

USB connectors are worse than RJ connectors and the most-easily contaminated
and corroded. I use O-ring grease in my USB connections too.

I hope this helps.

Subject: [ap-gto] Gold plating thickness on connectors

This might be a question for Chris Erikson out in Hawaii. But anybody with
information, please jump in.

The problem is that two 6 cond. Flat Modular phone cables (both 26 ga.) just
died in my mobile observatory after two years. And I've noticed that the
gold plating on several of my S-Video (don't ask) connectors is also looking
"funky" now.

For the first year I didn't have a dehumidifier in the observatory. But
when I noticed that a couple of steel screw-heads in electronic equipment
cases were starting to rust, I put in a chemical dehumidifier.
And since doing that, I have to dump water out of it every week. So there's
a lot of humidity in the observatory. I live in San Diego (12 miles from
the ocean, but it's still humid).

About 15 years ago when I went to my local large electronics store to buy
bulk modular connectors, they had two versions. The more expensive ones
said they were double-thickness gold plated and intended for repeated
plugging and unplugging. The cheaper standard gold thickness connectors
were for permanent installations.

But I don't see any plating thickness specs. on modular connectors now
-- at least none saying double-thickness, or intended for repeated plugging
and unplugging. And I suspect they're almost all coming from China now with
the very thinnest plating possible.

So, are modular connectors with thicker than standard gold plating still
available? And if so where? And what thickness should I actually be
looking for?

Thanks,
Woody

Re: Need advice with new Mach1GTO: Polar Alignment and drifting

horizontal crosshairs are parallel to east-west motion and the vertical crosshairs are parallel to north-south motion- correct?
Yes, that would simplify your task when doing drift alignment.

Always do azimuth drift align for zero Dec motion first.

Re: Issues with Windows 10 Build 1709

Hi Bryan,

 

I’ve been using 1709 and what I’ve found is sometimes you just need to reinstall the applications that are having problems. I am guessing  that 1709 moves the default location of some registry branches thus breaking COM interop and other functionality for some applications.

Bryan,

I am sorry you are having issues with latest and greatest Windows 10 version 1079. My last image resulted NASA APOD and I was using Windows 10 version 1079 without issues. Here is a list of my equipment and software:

1) A-P1100GTO using A-P V2 ASCOM driver version 5.10.00 (latest is 5.10.02).
2) QSI660wsg camera using latest driver
3) Optec/Starlight FocusLynx auto focuser hub using latest driver
4) SX Ultrastar autoguider using latest driver
5) Sequence Generator Pro (SGPro) version 2.6.0.25
6) PHD2 version v2.6.4dev5

I always have Windows Update disabled. When I want to update Windows, I always run a Windows Update manually and when it's finished, I disable Windows Update. This way my computer will never be updated without my supervision.

Peter

Re: More Troubles Tonight with APPM

I have a good idea what is happening, but don’t want to speculate on the group until I have studied Kerry’s APCC log files.  The engineering version that Eric mentions is a possible solution, and if the log files confirm my suspicion, I’ll send it to Kerry for testing.  The change that is in the engineering version will probably be in the next release of the GTOCP4 software.

Rolando,

 

Tonight I did the test as you indicated. At no time did I get any commerrors or slew failures or any unexpected parking behavior. 

 

I then tried another APPM mapping run and still got the comm errors, slew failures and the mount parked itself again after mapping about 6 points. It always seems to fail at the same point in the mapping run. Here is a link to a photo of the mount position when the slew fails and the comm errors occur and the mount parks. 

 

 

I also attached a screenshot of the mapping point in APPM when the errors occur:

 

 

The APPC log shows no command to park, but it does show unsafe slews. Before the APPM run, I even disabled the meridian and horizon limits in APCC thinking maybe it was affecting things but it didn't make any difference - neither were set to park when the limits were reached, just warn. 

 

After the failed APPM run I unparked the mount from its current position (in the photo) and subsequently used the APV2 driver to slew manually to the same position as in the picture and then even closer, almost touching the pier on both sides, with the counterweights up. I did not get any errors and slewing never failed. It only seems to occur during an APPM run.

 

Thanks,

Kerry

Re: Odd tracking/guiding behavior

Roland Christen
 

Cosmic ray hits are a known issue, and some nights are worse than others. I've had this happen on occasion, and if possible I use the smallest guide window to minimize errant guide moves.

Sorry Rolando, I should have been more clear.  In my case I know what the problem was with guiding.  What happened is that a spurious particle strike lit up a cluster of pixels on my guide cam and the guide software interpreted that as the real guide star shifting and issued errant guide commands.  With help from the people at PHD2 I changed the minimum star HFD value to prevent this kind of false positive in the future.  

It was hard for me to track down because I would see this happen on a very random basis, usually 1-2x per night and it wasn't consistent.  

My situation sounded a little like what Mike was experiencing so I thought I would see if he resolved it and if not perhaps this would help.

Hello Joel,

Please note that tracking is NOT the same as guiding. Tracking means open loop with no external software modifying the motion of the mount. Tracking means that an external program is sending move commands to the mount, thus modifying the motion of the mount. So, please specify what you are experiencing - is the mount simply tracking (sidereal motion on RA and zero motion on Dec) or are you sending guide commands to the mount which is causing the mount to move in ways you do not expect?

Re: Need advice with new Mach1GTO: Polar Alignment and drifting

Level and balance does not affect drift. need to know direction of drift, RA or Dec. Up/down/left/right has no meaning.

Level has little or no effect on drift of this magnitude. First need to establish which direction is RA, which is DEC.

Re: Need advice with new Mach1GTO: Polar Alignment and drifting

Roland Christen
 

What do you mean by drifting upwards? What direction is upwards?

Just remember this: Altitude axis affects the RA drift at the zenith. Azimuth adjustment affects DEC drift at the zenith and at the celestial equator.
Make sure that you have set your tracking rate to sidereal, NOT Solar or Lunar.

Thanks Roland

I tried last night but could never get Capella, near Zenith, to stop drifting upward regardless as to how far I adjusted with the altitude adjustment knob.  I'll try again tonight but it is not obvious at this point what I am doing wrong.  I was able to first adjust azimuth from drifting.

Start by adjusting the azimuth axis until a star at the meridian near the celestial equator does not drift in Dec. Once that is done, you have half of your alignment finished and won't need to adjust the azimuth any further.

Now all you need to do is adjust the altitude axis. Choose a star near the zenith and raise or lower your altitude axis until that star does not drift in RA. Your mount is now polar aligned and drift is zeroed out over a large portion of the sky.

Now you can adjust the RAPAS alignment so that it puts Polaris at the right point on the scale. From then on you won't have to do the drift align procedure, just use the RAPAs and you should be very close to the pole each time.

Re: Odd tracking/guiding behavior

Hello Joel,

What exactly are you seeing in your tracking/guiding behavior?

Please note that tracking is NOT the same as guiding. Tracking means open loop with no external software modifying the motion of the mount. Tracking means that an external program is sending move commands to the mount, thus modifying the motion of the mount. So, please specify what you are experiencing - is the mount simply tracking (sidereal motion on RA and zero motion on Dec) or are you sending guide commands to the mount which is causing the mount to move in ways you do not expect?
