1600GTO Encoder LED Color #Absolute_Encoders

Hello,

I recently bought a used 1600 with AE from the original owner.  It is raining here in California, so I have not been able to use it to image yet, but have been testing it in the garage.  Using APCC-Pro, I hooked it up and played with it.  I don't get any errors, and the AE tab is available and the encoders are enabled.  I noticed that there is a Green LED showing on the RA AE cover, but the DEC AE cover led is orange.  Is this normal, or is something set up incorrectly?

You would be incorrect.   The blunt looking end is the folded down lip.  If pushed it forward, it does extend and lock down and look identical to the black side, but rather than staying in place, it pops back up and slides back when any tension is put on it (like any tension on the wire as you disconnect, even though primarily I would hold the connector in this case as it is wire-to-wire). 

My GUESS is that the inside is rounded out in some fashion, though it does not show to the eye.   Or it might be something off in the shape of the inside of the red connector.  It just has no strength once it clicks in (and it does).  Normally these things require a tool to lift the lip up to slide off the connector's plate, this one just requires a tug.

You are of course correct, it's just that Powerwerx is the only place I have seen them for sale (I have not searched, there certainly could be others).  I tend to think of them synonymously, but they are not. 

My real point is Amazon is filled with knockoffs, also knockoffs of the crimpers, and by reputation (though I did not try) many of both are of low quality.

Been there, done that, got the T-shirt.  If that’s the problem you might need the PP connector removal tool (yellow handle), or just chop off both connectors and start again – and make sure both are inserted into the plastic housings correctly.

Already done.  I would have been less surprised if I had a bad crimp, but the crimp was strong, it was the connector at issue.

I have powerpoles everywhere, I generally love them.  And by the way, these are real Powerwerx connectors, not the Amazon knockoffs. 

Now whether this was really the issue... I guess only time will tell.

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

Ray Gralak
 

Hi Marcelo,

A few questions:

1. How old is the model?
2. How many points does it use?
3. Did the issue always happen, or did it start a while after the model was created?
4. Is the scope mounted on a permanent pier?

Also, if you are not using APCC 1.9, you should update. (You do not need a subscription to update to the latest build. If your license is older, you may not get the new major features, but you will still get bug fixes and minor feature improvements.)

-Ray

I was finally able to complete the tests. First, the effect is actually present on the Dec axis. Then in the 5 and 1
second frames with the modeling activated, the stars are beautiful and round, without any problems.
Examples below:


Oval stars in the first frames after the meridian, 4 minutes exposure, modeling on (then from the fourth, they
are round again):



4 minutes, modeling off (elongation appears to be the same):





5 seconds, modeling activated:



1 second, modeling on:

Excellent!
Ok, that rules out the mount as causing this. So we are back to an error in the model. So perhaps your model is sending the Dec in the opposite direction for a period of time after the meridian swap. I'll let Ray comment.

Re: #ASI_AIR_PLUS What should my expectations be with AP? #asi_air_plus

I have used the ASI pro with the Mach2 . It works but not perfectly. The home position does not bring it home. There is also no CP5 tab in the software. It works using cp2.

Hello, I have been using the ASI Air Pro and Plus now for the last 2 years and it has really made my imaging experience a very reliable, repeatable, and failsafe process. Eliminating a PC from my workflow has revolutionized my imaging experience and made imaging alot more comfortable.  I primarily image remotely at darksites and from home on my back porch.
My 2 current mounts are a Celestron CGE classic and a iOptron Cem25. I have full control over these 2 mounts when using AA+ and AAP.  Plate solving, homing, guiding, polar alignment, automated meridian flips, parking the mount after the image session is complete, every feature in the zwo ap which automates the mount through AA+ works perfectly. 

I have been wanting to replace the CGE with a larger mount that can better handle the moment arm of my 12" Newtonian and effectively guide the Newtonian when I use a 2.7x barlow.  For this reason I have taken interest in AP 900, 1200, Mach 2, and 1100.  In my research regarding compatibility with the AA+ however, I keep seeing things that really make me uncomfortable investing in such an expensive mount only to have it not cooperate the way the low end mounts do. 
So far I have read that the AP mounts can have issues parking and doing merdian flips.  I am unclear if this is an HC issue or a CP version issue. Maybe it could be an indi driver issue, which is what ZWO is using to run the AP mounts.

Can anyone offer feedback on their experiences with either AAP or AA+?  I am really hoping someone has figured out a way to achieve full automation from start to finish.  Being able to do this successfully would help me re gain confidence in using an AP as what I would hope to consider my forever mount.

I would be interested in hearing about this too.  I do plan on picking up the QTCC for an anticipated new TEC140FL in the coming year.  It would be nice to have the option of picking up a field flattener as well.

Last night I was able to do some tests, but the clouds interrupted the process.
 
As preliminary results this happens on the Ra axis. Also when testing with modeling off the stars are slightly less oval after the meridian (of course, with modeling off the elongation is the same after several frames, before and after the meridian).
 
Tonight should be clear and I should be able to test again.
