Luke,
I wonder if the setscrew for the worm spur gear is loose.  This happened to me and symptoms are similar.  See the last part of the attached AP  Gear Mesh doc for "Loose spur gear setscrew".

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.

I'm very pleased with my Planet, though I would not leave wood outside all the time, it comes in each night.

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).

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. 

 

I will now be making daily checks of all the clamps!

Leveling is straight forward, nothing unique.

 

I believe AP is only selling and shipping these tripods with the double leg clamps now.  But if not, you absolutely want the double leg clamp option.  I’m speaking from experience.  Wood does expand and contract.  And after three days and nights of hot days and cool damp nights, one of my clamps loosened enough for a leg to slip – and the tripod with mount and scopes toppled over.  I was at a multi-day star party and a TeleVue representative across from me came over and said he’s had the exact same thing happen to him with TV’s wooden tripods.  So now every time he passes by one of his wooden tripods, he double checks each leg clamp.  I had AP order me the optional second clamps and have never had a leg slip since.

 

My main reason for having the wooden Berlebach tripod is looks and feel.  It’s a conversation piece for public outreach.  And I just really like the look and feel of wood.  I might add that I now have three Berlebach tripods, Planet, Uni, and Report.  And I use all three for public outreach – for various purposes.

 

If you intend to use the tripod in dirt or sand, then the wooden one is probably better as some metal devices (particularly those involving metal-to-metal sliding parts), might not do so well in dirt or sand.

 

If you are only concerned with function and efficiency – I’d probably go with one of the high-tech alternatives to wood.

Hi Astro Buddies,
I'm needing a portable tripod for Mach1 for occasional venture beyond home observatory.
My main priority is ease of setup / leveling - No visual - AP use only. 
I probably won't use it much based on my 20 years mucking with this hobby. (-:
Both are outstanding products based on AP Quality.
But If price is not main factor, which would U suggest?

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

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.

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.

Mike,

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.

Eagle tripod, I have two with lots of accessories. To be clear though I have never used the Berlebach tripod so I cannot compare the Eagle to it.  BTW, great idea Jeff with the Piano Caster Protectors.

I also put some Piano Caster Protectors under the feet to save the aluminum.  (I drilled them out with a forstner so the foot sits in a perfectly sized pocket.)

If your telescope is located at your home property, you could connect CP4/5 to your home network using your existing router/access point? You can easily configure your CP4/5 via web access.
