Catching up a bit, but did you try with usb instead of LAN? Not that it should matter.

Many thanks. Yes, I thought of that.  I tried ports up to 32 (which appears the max in APCC) and had the exact same result. The virtual port gets created (according to APCC) but when I try to use it I get Mount Not Found errors. However, I didn't try that by itself -- APCC was still trying to use 4 and 6. I'll delete all ports and then try a higher port to see if that works.

I also checked all port assignments, including hidden devices, and 4 and 6 are not used by anything else.

I rarely reply to these posts because I am often wrong. However, never in doubt.

Anyway, the virtual ports are low and could be messing with other system ports. I set my virtual ports at 21 and 22.

Maybe worth trying.

Cheers,

Re: APCC / APPM Frustration

I was about to suggest the same. I use 24 and 25, but just something high that won’t conflict with other gear that may need the lower ports.

I was planning to use my new AP130GTX just for visual observing through the springtime, so that I could capture galaxies with my SCT, but it didn't work out that way.

Part of it is impatience on my part to get imaging with the scope, and part of it is weather.  In terms of imaging, I suspect that my site is not going to be great for very high resolution imaging.  Since we're on the leeward side of the Cascade mountains, the seeing is quite a bit softer than what I was used to on the west side of the mountains.  Because of that, imaging at 0.3 arc seconds per pixel doesn't give awesome results.  My QSI camera on the AP130GTX is just about 0.8 arc seconds per pixel, which works out better.  The second weather impact is that visual observing at this time of year is less than pleasant.  We're in the mid to low 30s at night, which isn't bad in itself, but combine that with 30mph winds, and it gets really cold, really fast.  So with all of that, I moved the camera gear from the SCT to the new scope.

I'm posting here, instead of AP-UG, since the thing that I am blown away by is the performance of my AP1600 with absolute encoders.  I've known all along that I've been fighting with mirror shift and flex with my SCT, but I had no idea how much - until now.

The weather conditions last night were pretty poor.  The sky was cloudless, but that was the only good thing.  The transparency was marginal, the seeing was poor, and it was windy.  The winds were about 25mph to 30mph for most of the night.  There were gusts that rattled the windows (unfortunately, this is not uncommon here).  When I was exercising each part of the system, I ran for a while with my OAG and PHD2.  The best I could get was about 1.2 arc seconds RMS, with the scatter plot pretty much random within about a 3 arc second circle.  I went ahead and built an APCC Pro pointing model with about 180 points and then did some more testing.

The pointing accuracy was striking, as compared to what I am used to with the SCT.  It was pretty much putting any target I selected right at the center of the field, no matter where in the sky.  But what really impressed me was the unguided performance.  After creating the pointing and tracking models, I ran a sequence in NINA of 10 minute exposures for the rest of the night, unguided.  Even with the gusty wind, the subs looked great (even if soft from the seeing).  When I processed the image, there were no subs that needed to be tossed, so I kept them all.

To say that I am happy would be a huge understatement.  Even though I've been using Astro-Physics mounts for almost 10 years, I am simply amazed at what they can do when you put a top shelf scope on them.  Wow.  The biggest downside is that the data is so good, that my processing skills are well short of taking advantage.

Speaking of processing, the processing of this data was minimal.  After calibration/integration, I spent between 25 and 30 minutes processing the combined channels.  I did not do any noise reduction (except for MureDenoise) and sharpening, since I wanted to show the quality of the data from the system.

Re: About APCC and ISS tracking and PC Time

W Hilmo
 

This is great information!

 

I have been using a free tool called GPSTime (https://www.coaa.co.uk/gpstime.htm), and it works ok.  I took a look at NMEATime and it looks to be far superior.  Since it installs as a service, I just need to make sure that my cheap GPS dongle is plugged in, and it takes care of the rest.

 

In my opinion, it’s well worth the cost, so I went ahead and purchased it.

https://kb.meinbergglobal.com/kb/time_sync/timekeeping_on_windows/accurate_time_in_windows

As for using a GPS to sync the signal timecode to the host, I do this now using a $15 USB GPS dongle from Amazon and the NMEATime2 app from VisualGPS: http://visualgps.net/#nmeatime2-content

NMEATime2 does it right, including calibrating for the delay between the signal being emitted, received, and working its way through the OS to the app. This delay calibration is key for any app that's used to keep time with any signal source and why you can't just read the GPS sentences as they come off the serial port and write that time to the OS clock. It's pretty good for $20 and change, and a total solution for under $40 if you include the cost of any USB GPS dongle.

I was wondering if it is some delay from the wireless connection from the ipad to the asi air. Also possible is the cable/ wifi problem from mount to asi air. I cannot be sure which.

Re: A Question Regarding an AP900 Mount

Liam, thx for the quick reply.

I am using the CP2 as my mount is from the early 2000's.

I'm connected from the ASI Pro via a USB to serial cable.

You don't think it could be the CP2 to dec axis cable? 

I've also noticed poor tracking even unguided. In a 5 minute exposure I sometimes see a double image. Which is why I'm questioning the CP2 to dec axis cable and not the serial cable.

Thoughts?

Chris,

 

What  CPx are you using to drive the motors? A CP3 or a CP4?

 

If the keypad has no issue moving the dec axis, then the motors and the mount are fine. I suspect a software issue or cable issue. I would start with using a different cable and connector to reach the CPx. For example, on a CP3 you could swap out your serial cable and use the second serial port.

Re: Mach2 Slew Speed, Power, and Voltage Question #Mach2GTO

michaeljhanson@...
 

Hi Greg,

I hear two different questions.
1) What is the max permissible input voltage to the CP5?
2) Can I use a 24V battery charger.

For question 1, no one likes to hear, "it depends".  So, the keypad has a max input voltage of 28.0V.  This is where the 28V "specsmanship" number, mentioned in the other thread, comes from. 

This answer is unsatisfying, so we can be more pragmatic by entertaining question 2 instead of question 1.  I think this is really what you are wanting to understand.
A proper three-stage charger can provide up to 29.4V absorption voltage at the max absorption set point.  This exceeds the keypad rating.  Are you even using a keypad???
If not, the next "limit" is the transient suppression, which can begin conducting at 29.5V.  While the margin sounds low, the suppression voltage has a large positive temp coefficient when it begins to conduct, and, there will be losses in the power cable to the CP5 contributing to margin.  So, the margin is much higher than it seems.  So, if you do not have a keypad plugged in, I see no issue using a battery charger. 

Suppose you DO have a keypad.  Do you know the absorption set point of the charger?  Does the charger even have an absorption set point? If so, do you have control over it?  Does it transition from absorption to float properly (does it even have a float stage)?   Can you measure the highest charge voltage?  If the answers are "no", I would be reluctant to have a keypad plugged in while charging.  Reason is, there's just too many crappy chargers out there, with no possibility of us testing every one of them.  An absorption voltage set point can be as low as 28.2V.  We know that, even with the mount parked, there will be a couple tenths drop in the power to the keypad through two harnesses.  *IF* you know the absorption voltage to be at the low end of typical, I see no issue using a charger even with a keypad.

I hope this helps.

Mike Hanson

New user APCC Meridian Limits question, managing limits across different scopes #APCC

skester@...
 

Last night I used the tracking limit explorer to define meridian limits for the first time and the process worked very well.  My question involves keeping track of the correct limit file across scopes that have drastically different limits.  My C11 is back heavy and short, allowing it to go well past the meridian.  The MN190 is front heavy and long and will impact the tripod much sooner.  I know I can save the limit files and using a recognizable name pick the correct file.  However unless I am missing something it doesn't appear the name of the file in use is displayed by APCC.  Does APCC have a similar concept to SGPs 'equipment profile' that I overlooked?  If not the limit file name method will work, I just have to be careful to select the correct file per session.

You can insert a Phillips screwdriver in the Tommy bar hole and use it for leverage to loosen the shaft adapter (there are no lock screws).   However, my question is why are you removing it?   Nothing inside needs cleaned.     Use a soft cloth and Windex to clean the surface of the mount.

 

Regards,

 

George

Subject: [ap-gto] Mach 1 Counterweight Hole

 

Hello all.  Just joined, 1st post.  So I just purchased a second hand Mach 1.  It was well loved, and that's a good thing btw, but I am trying to disassemble the mount 8n a feasible manner so I can get all the dirt, grime, etc out of it.  I just ordered a grease kit, so I will be going through that evolution as well.  My question is on potential removal of the piece which accepts the CW shaft.  It appears as though it should be removable, but I can't seem to get it to budge.  Is it indeed removable, and if so is there a retention screw somewhere that is locking it in place?  I didn't souse down on it too much for fear of damaging something, but it is not moving.  Any guidance would be appreciated very much.

Thanks. I'll try again in the daytime today just to see if I can get the connections to work.
