Ray,

My apologies.  This was the first time that I've submitted a log for review.  The place where I had the log zipper shortcut was only pulling up the ASCOM logs.  Using the link in APCC I was able to zip the rest of what I think you need.  I only included logs which bound the time in question.

Could this be a date/time issue on the mount? Do you have a keypad attached to the mount, and is it in EXT mode or not? Could its time be off?

I just happened to be looking at the Site tab when that happened. The 23' 59" time remaining in the screenshot was taken when I first noticed the error, so easily a couple tens of minutes before the correction occurred.

For completeness, the horizon countdown timer was operating when it was displaying the incorrect "time before limit reached." It wasn't just a static screen, and we're talking a several hour delta between what was displayed and what the actual limit was. In hindsight I wish I would have let it run out to see if it triggered the "Stop Tracking" command. I don't usually monitor an imaging session, so I have no idea if this has happened before or if it was just a one-off fluke. If the situation recreates itself I'll let the limit timer expire to see what happens.

I was paying attention this time simply because I was exercising a fully automated N.I.N.A. advanced profile for the first time, including a Dec Arc model (Awesome plug-in Dale, thanks!) and Smart Meridian Flip. The APCC GUI was sometimes minimized, and sometimes not. It's set to stay up front when not minimized, so there were plenty of opportunities for the screen to refresh itself. I was hours into the run before I noticed it.

As a sidebar, I highly recommend N.I.N.A. for those who haven't tried the latest incarnation. It has come a long way, very elegant. I was a SGP user for several years before trying N.I.N.A. 2.0 after reading comments on it from other AP owners. The versatility the advanced profile sequencer provides is really quite impressive.

I'll keep an eye on this moving forward.

Eric,

I guess it is possible there is a bug in this calculation. When I get a chance I'll try to reproduce the values from your horizon limits file and the sky position captured in your screen shot. I am not sure I have all of the information though as you only provided the ASCOM log and not APCC or PNT files

Eric,

If it's not that this it's likely a graphics issue on your computer. APCC does not recalculate the Horizons limit time when switching between tabs.

Interesting article. I haven't seen that before. I am using Win 10 Pro, not Pro for Workstations. Nevertheless,
I recreated the authors conditions by artificially fully loading my CPU (screenshot attached). As you can see,
only 1 socket is shown. I verified in my BIOS that SMT is enabled. My MB is an ASUS Zenith II Extreme

Re: Unusual APCC and Mach 2 behavior after the meridian #APCC #Mach2GTO

Hi Marcelo,

There are many reasons that could happen, but probably the model is not accounting for random shifting of the scope/camera after the pier flip. This is probably something that you will have to track down.

First, I'm doing 4 minute unguided imaging with an Esprit 100 on my Mach 2 (with modeling turned on). And I
don't know if it's a factor to take into account, but it's summer here and the nights are hot, around 19C.

Thing is, just after the meridian flip I'm getting oval stars. The strange thing is that it's exactly the first 3
frames, in the first one the stars are very oval and then they get progressively better, by the fourth one they
are round again (and before the meridian they are also normal).

It's not a big problem, but I'm curious what could be causing this. The images are a crop of the central area.

Thanks

Eric,

Are you running Windows 10 Pro, or Windows 10 Windows 10 Pro for Workstations?

If you are just running Windows 10 Pro, there may be a software issue with that CPU because Windows thinks there are 2 CPUs unless you disable SMT. See this link:

No, no remote desktop of any kind. APCC-Pro runs on my desktop and that's where I took those

Hi Eric,

Switching between tabs does not cause a recalculation, so it is almost certainly an issue with graphics on your computer. I can't think of another reason why this could happen.

Re: AP155 EDF Field Flattener

dvjbaja
 

Give AP a call when they return from the holiday break.  I've read that they were making more field flattener optics, but for which scopes need to be checked.  The 155 can produce exceptional results with the 4" diameter f/7.1 field flattener, and the TCC which I recall put the scope at f/5.5. 

Good luck!


Re: Odd APCC-PRO behavior with horizon limits "Time before limit reached" #APCC

Ray Gralak
 

Hi Eric,

That looks like it could be a user interface glitch that was corrected by switching from the Horizon tab and back to it.

Were you using a remote desktop application to connect to the computer running APCC? Some remote desktop applications have been known to display stale graphics at times.

Or, it could be a graphics driver issue. What computer model and graphics card (if any) are you using?

Unfortunately, log files will not help in this case as the horizon limit is not recorded.

This evening I noticed appc-pro was reporting that I would reach my horizon limit significantly before my actual
horizon limit would occur. I checked my hrz file and didn't see anything odd. I switched to the "site" tab to
check the time and site info, it was correct. When I switched back to the horizon tab the "time before limit

Re: AP155 EDF Field Flattener

Howard Ritter
 

Hi, Ken—

After I had retired, I too decided to take up astroimaaging (what people of our vintage still tend to call astrophotography) with my 155EDF. When I decided to upgrade its original 2.7” focuser earlier this year, I just missed getting the last available (forever, I think) 4” and associated TCC. But there was an upcoming production run of the 3.5” focuser, and I obtained one along with the QUAD-TCC telecompressor-field flattener.

Someone from AP will undoubtedly answer your question, but I think the answer will be that a FF for your focuser would have to come from the used market. And that’s only if the critical dimensions of the Feather Touch match those of the AP 4” unit. Or perhaps someone makes, or can make (Precise Parts?), an adapter. If none of the above, the alternative might have to be to do what I did. The two 3.5” components are priced at about $3000 total (when they’re available, which they don’t seem to be at the moment).

Good luck!
