Quick question. I get this error message every time that I try to start APPM using NINA - see attached screenshot.
I saved the file several times over the old one and also tried to delete the old one and save a new one. It looks like
APPM Is unable to load the settings file.
When I start APPM manually it starts fine however it looks like the points are not updated per NINA's plugin
settings.
I didn't see anything obvious int he logs. Has anyone had this happen before?

Re: Question about 130GTX with field flattener

Roland Christen
 

There is no way the scope will cause this problem, so it would do no good to send it in. You can send the field flattener and we can check it out, but I doubt very much that it can cause what you are seeing. 

These cameras are notorious for sensor tilt. If you go on the AP user group there are many people who have had the same issue and have successfully fixed it by using some new software that is now available for this specific issue. Go to main@ap-ug.groups.io,and also main@ap-gto.groups.io, and ask our users to help you.

Hi Roland,

I have been trying to image with the field flattener for my 130GTX with a 6200MM camera. I have adjusted for tilt and for spacing following instructions on your website, but the stars at the four corners are not symmetric. One corner elongation is particularly strong when slightly defocused (inside of focus), such that my autofocus cannot reliably make the stars round. It is possible to manually make the stars round, but they will have to be slightly defocused (outside of focus).

I wasn’t able to fix this issue by adjusting spacing and sensor tilt. I have already spent weeks on this. Could I send the FF and/or the scope in for an inspection?

Thanks in advance,

Yuxuan

Re: AP Berlebach or Eagle Tripod - Which should I get?

Now that you mention it, I guess there’s really no reason to line a hole with a piece of pipe, is there, if the concrete of the patio is in good condition. With respect to locating the holes, it seems to me that all that would be necessary is to use the 600’s polar scope to orient the tripod with both Az adjustments on the mount and the tripod head in their center positions, then drill the holes and position the tripod, and only then do a NINA alignment. No point in doing a precise alignment before drilling the holes, when a repeat will be necessary anyway after they’re sunk. After that, I’m hoping that positioning will be repeatable enough to allow autoguiding without repeat NINA alignment.

Re: AP Berlebach or Eagle Tripod - Which should I get?

Howard Ritter
 

Thanks for the tip. But with my 1-clamp Planet carrying a relatively light load, I may not need to do this. But I’ll have to re-think my idea of leaving the 2-clamp Planet with the 600E mount out on the patio under a 365 cover from spring to fall. My thought has been to sink stubs of copper or PVC pipe into the concrete at the places where the tripod points touch, so the tripod remains securely fixed in position for extended stays. The orientation would also be repeatable in the interest of polar alignment if spells of wet weather make it a good idea to bring the tripod in for the duration. The key I think will be to use pipe whose I.D. exactly fits the tapered spike at some point below or at the ground disc. This should make for azimuthal orientation, tip, and tilt to be pretty rigidly constrained and repeatable.

I’m getting a 1600GTO mount in May, and it’s going to carry the OTA of my 16” Meade SCT, at least initially. It will remain outside, under a 365 cover, but it’ll be carried on the SCT’s original Giant Field Tripod.

You can add a second clamp yourself if you are slightly handy with woodworking (it requires a hole about 1/2" wide and deep - not all the way through -- drilled into the side of the disassembled leg).  I added my second clamp fairly high up the leg above the tray for even more grip (you lose height matching how far apart they are, but I use it all the way down anyway).

Hi all. I normally store my AP1200 under a portable Gazebo, which is then covered by a Tarp . This is semi permanently setup in my front yard. The mount has counterweights left on the shaft but the scope /camera etc is taken indoors each night. Due to inclement weather over the past week I took the mount in, gave the motor cables a clean with contact clean, pulled the cover off the GTOCP3 control box to check no dust/insect ingress, etc . All looked good so put it back together and replaced the mount onto the pier. Last night I went to use the mount and it was just not working. Would not reliably slew to object from the parked position, at times it was not tracking in RA and would not seem to even track an object. I could not even get it to calibrate in PHD2. When I was looping 2 sec subs in PHD2 the guide stars were drifting across the filed noticably as if the RA axis was not working, however the Dec and RA axis would move when manually slewed. After pulling my hair out for 2 hours I gave up. It was then that I noticed the pier has shifted from its normal position. My wife finally confessed to accidently driving into my pier/mount with the ride on mower just prior to me removing the mount for a little maintenance. Today in daylight I examined the mount and noticed the RA worm housing rocks back and worth as shown in the video. The housing screws are tight, I checked them. I guess my concern being,  has a sudden hit to the mount caused any damage. I know the polar alignment has shifted a bit but the behaviour of the mount last night was unexplainable. I have also attached the PHD2 guide graph. Its crazy. My usual routine is to power up and unpark from Park 1 with the keypad, the run NINA, connect to mount, select object slew etc and off I go. Last night that routine went crazy , I removed the keypad and Unparked from within ASCOM, but still results not as expect slews way off. Could a misalignment of the pole produce this? Unfortunately weather so poor it may be many days before I can try again under clear skies.

Howard,

 

You can buy a second set of leg clamps and install them yourself.  That’s what I did on my Planet.  I don’t recall the details, but I do remember running into a minor confusion regarding the instructions and reality.  So I reverted to photos and all went well.

 

So far as I know, the leg slipping problem only shows up after the tripod has been outside for more than one night in a row.  But yes, check clamps routinely.

I have two Planets, a double-clamp model carrying my 155EDF on a 600E mount (a recent replacement for the 25-year-old original) and a single-clamp model that I scored on a special deal from a retailer. It carries a much lighter load, either an APM 100mm binoscope on an APM altaz fork or my Rainbow RST135 with a WO FLT91 or RASA 8. All the setups look gorgeous.

Yes.  

What I and a lot of people do is put in a small travel router.  I put mine on a separate subnet from the house; it forms an access point and hands out IP's to anything connecting (e.g. my cell phone or laptop), it has a wired connection to the CP4, and a wired connection to the NUC that lives on the tripod.  If it's at home it meshes with my home network and routes to it, and then has internet capability.  If i'm at a dark site where it is the only thing, then my laptop and phone can talk to the NUC and if needed each other as well. 

It's worth noting that some years ago you could do all this with a mini comptuer / NUC, but Microsoft changed things around where the wifi in most of them cannot form an access point, it can only join a wifi network, not be one. 

Some level of networking expertise can be needed to make it do all those things at once, but the key is getting a device that is really intended as a networking switch/router/AP.   There are a lot that are 12V and low power requirements.  And having a wired connection to the CP4 and your local NUC or whatever is more reliable than wifi.

Re: How do I get two computers connected to the GTOCP4 WiFi to talk to each other?

Nick Iversen
 

OK I've got it now. The feature I am talking about is called "Client Isolation." On WiFi networks you can have Client Isolation which means that clients can't talk to each other. You can turn it off in your router. 

So it looks like the GTOCP4 has it turned on. My question then becomes - "Can I turn it off?" I'm guessing that the answer is no.

Looks like a separate router attached to either the ethernet port of the GTOCP4 or a WiFi bridge with Client Isolation turned off is the way to go.


Re: AP Berlebach or Eagle Tripod - Which should I get?

I have both for my Mach1.  If I had purchased the Eagle first I wouldn't have ever purchased the Berlebach.  The Eagle is a much more rigid platform for the mount.  I leave my mount set up on the Eagle under a 365 cover most of the time and probably only need to touch up the polar alignment once a month.  Also the Berlebach is affected by moderate heat and humidity more than I thought it would be - it will move a fair amount from one night to the next.

You might want to consider the Avalon T-130 or the T-110 tripods.  Excellent for small mounts, carry bag included, lightweight design, leveling,  folds easily.  Comes in red or black.  The T-110 is the same design, just a little bit shorter legs.

I think it does. 

This is my understanding also.   

The WiFi is not point to point for clients (Eg just because they are in the same address range).   WiFi packets are received by the WiFi router then forwarded over wifi to the destination device.  

(If this weren’t the case then two WiFi devices could continue to talk to each other when outside of the AP WiFi range. Pretty sure it doesn’t work this way.)

So.. the question still remains … does the CP4/5 do WiFi routing?
(I did see Howard’s note, but haven’t seen a definitive follow up. 
Fwiw , I would suggest leaving the CP4/5 to tasks for which it is suited/designed for and WiFi routing to a purpose built cheap router.  This way if , for example, one needs to restart the CP4/5 WiFi is not interrupted.  But The AP team has better experience than myself in this area. )


Serving up DHCP addresses and routing are two different functions. I suspect (but I don't know) the intent of the access point was to allow devices to communicate with the CP4.
