Briefly, new user of a newly purchased AZMP.  I have done nothing to it, and used it for the first time this afternoon after the sun had nearly set and was behind trees.  Initializing, the mount revolved, and then asked if I wanted to align.  I said yes, and let it find what it wanted (a reasonable first attempt to see if I can have confidence in it, and also if I understand the prompts and 'quick start' guide).  It went to the Sun, which it apparently thought was about 5 deg below the western horizon. Not a salutary start.

 

I managed to get to the point, poking buttons, to where it offered to find Venus.  Progress!  I accepted the invitation, and it slewed to within 5 or six degrees of Venus, with about the correct altitude on the 127 Mak I had mounted.  I couldn't see Venus in the view, and nor could I spot it in the glare of the western horizon at sunset. So I shut off the mount, but not before asking it to find its neutral/zero position. It did that, but was about 6 degrees westerly from where it had started when I began the initializing procedure (I used my phone compass to aim the mount's head due south before powering up the first time).  

 

Hmmm.  I picked up the mount, OTA and all, and rotated it due south again.  I also touched up the altitude by about two degrees because it was tilted. Lined up the scope's tube with a vertical edge of the mount head.  Verified that the mount was level...again. I went inside for a while, waiting for Venus to show up better.  

 

Went out 15 minutes later and saw Venus right away when I looked up.  Good.  Started up the mount, it rotated, and when I asked it to look for a solar system object, this time it offered the Moon.  Good, that is what I had hoped for 20 minutes earlier.  It was not offered then.  I let the mount find the Moon, which I was relieved to find it do almost correctly, and I aligned it with the direction/arrow buttons (maybe 20 minutes in both alt/az).  Pressed enter, and I enjoyed the Moon for several minutes, and even got the missus to come take a look.

 

With all that reported, did I actually do it some good when the mount had been turned off, zero'd, and I moved the tripod in azimuth, and also did a slight tilt adjustment to get the OTA and its clamp very close to vertical? I was sure the mount would be off by many degrees due to my changes.  It seemed, from reading several threads over the past four/five years, that returning the mount to zero is important.  Apparently....not quite so much?

 

Have pretty much all of you purchased the teflon washer from biz and replaced the stock one? I think I'm beginning to appreciate why.  There's no give to the metal one, and it will loosen with even the slightest backing off of the ring.  BYW, iOptron is including the small pins for that locking knob now.  At least, four of them were provided to me. Some of you won't be so happy to see this. mad.gif

 

I didn't bother leveling the tripod.  I appreciate that it would need to be leveled mostly, closely, on rocky and uneven terrain, even on gravel, but when I was using it this evening it was on a concrete driveway, pretty close to level.  So, I relied on the leveling knobs to do what was needed to level the mount.  Also, because I didn't want to do a lot of work or buy anything, I cut out a section of the sliding window-mounting plastic adjustable (telescoping) inserts that one would use for a portable air conditioner...if you follow my description.  If you use a portable air conditioner tower, the outflow must be directed out a nearby window, and the large hose mounts on a telescoping insert that you slide the window back against.  It has curved sides.  I cut out a section of that, unused of course, and laid that atop the mount head, over the GPS cover, curved edges down so that the whole was suspended above the curved cap and the GPS cap.  I then used a digital torpedo level at 90 deg, but laid at 45 deg like a crossbuck at a railroad.  Might be an idea for some of you.

 

Another question: I have read that some units would not take a substantial charge, if at all, when their users first got them.  Mine charged, with the red LED showing on the wall wart, for about 35 minutes, and then the light went green.  That didn't seem right to me, but...what do I know?  I waited until the next day and tried again, but this time the red LED turned to green at about the 8 minute mark.  In total today, the mount was powered maybe 20 minutes and it didn't have a single hiccup in motion, and the paddle responded to every tap I placed on it.  What I don't know, unless you can point out an indicator, whether on the body or on the paddle, how much charge it had, and how much of it is left. ???  How long did yours first charge, if you can recall all this time later?

 

As a quick report of its performance, I mounted a roughly 10 lb. MAK OTA with Tak 1.25" prism and a 32 mm Televue Plossl on the primary side, and I felt I needed to balance it with the single 10 lb smallish counterweight on the B side. The counterweight was maybe an inch away from the knurled locking collar for the slide-out counterweight tube. Not far at all.  I'm happy to report that the mount operated like a champ, no grinding or groaning....gratifyingly quiet!!  Both axes.

 

So far, I like the mount and have confidence in it.  I haven't seen anything that makes me feel it's going to be some trouble to get it to operate reliably.  It seems very well designed and made.  The paddle hangar....maybe it was always meant to be disposable?  I think a molded receptacle might have been a better idea, built right into the mount head. 

 

That got a little long and convoluted.  Thanks for anything you care to offer.

Hi Inkie,

When first using this mount I’ve found it best to manually set the zero . Then point the mounts bubble level to south. Then do an alignment. I only align manually as I found it best for me…. Getting it level is most important for good targeting.

If you do not have my PDF’s for levelling and balancing in azimuth then please sing out and put these up here again. These will help to get good performance. Once you get the hang of it this mount is simple to use.

cheers

Graham

Thanks, Graham.  Your thoughtful pdfs were the first things I found.  I have them squirreled away in my Astronomy folder. grin.gif

 

I had read of your decision to hit 'back' and just do a manual align, and was going to do that if the second attempt had failed.  It worked, and I just forgot and enjoyed Luna with the missus.  I think you must have found that it's much less hassle, and quicker.  I think I might default to that in time, but for now I will try the scope as it was intended mostly to ensure I don't have a lemon.  So far, so good...

 

Could I ask, what, exactly is the 'zero' position?  Is it where the bubble faces geographic or magnetic south, and when the scope clamp is precisely vertical?  Did I do any good by correcting the vertical orientation of the clamp after power-off as I explained earlier?

Inkie,

Yes zero to me is when the scope Is vertical and the bubble faces south.. that is your start off position.

As I mentioned I’ve found with new mounts it’s best to go into the menu and set this yourself just this once and then less trouble from then on.. 
And yes I’ve found manual alignment less hassle and quicker and I get better targeting that way.  Each to their own though.

As I’ve mentioned many times , balancing and levelling are most important for best performance. This goes back to the early days of the mini towers and is still the same for this mount. This is why I wrote up these two PDF’s for the mini towers which can be used for this new mount as well with a little difference which is noted in the PDF.

To your question about correcting the vertical positioning after power off. Answer is no. Refer back my first paragraph above
Have fun

cheers

Graham

Graham is the man when it comes to these mounts.  I have an original minitower, and what I have found is that leveling is probably the most important thing.   I do my best to get things set to the zero position as they put it, but for me that means lining up the back of the arrow with Polaris(the original tower had an arrow that you needed to point due south).  I use a wide fov eyepiece an find the first target.  Usually something obvious like the moon or Jupiter or Vega, etc….  Goto,  center and sync.   If i have things leveled well, one sync is usually good enough to get the rest of the targets in the FoV.   I bounce around the sky, syncing at each target and that seems to do the trick.   But, if you are even just a little bit off level, you will be chasing objects all night.  This is true for all alt/az goto mounts.

I have followed Graham's advice and can confirm that what he says is the way to go.

 

I've had an AZMP since Dec 2016 and it still works great. I have a 5" f/7.5 (22 lbs) mounted on it.  The battery is still going strong.

Hi Bob,

Im pleased that the advice you ask for has helped you work this mount.

Enjoy

As soon as these show up at Astronomics my name is on the list for one, Patience .

Ive been in contact with Graham and have the teflon washer on the way, looks like I’ll have the washer before the mount.

Also have the pdfs saved , I’m sure there will be questions , these threads are great to follow.

Hello,

Is using a digital level (such as the app on my iphone) accurate enough to level this mount?

I have this mount coming in the next day or two...

thanks!

I don’t expect your iPhone to be accurate enough as there is no flat surface to rest it on.

The inbuilt bubble level is absolutely fine if you follow my levelling PDF. Practice using it during daylight hours until you get the hang of it and you will have perfect level.  I can level mine using this method in about 20 seconds .

cheers

Thanks Graham!

Your welcome.

Here is my azimuth balancing PDF to help as well… take particular care when going thru this and please “don’t “ foreget to reinstall the 3 screws I mention and tighten firmly.  These 3 screws are removed only once for this procedure so balance all you OTA’s at this time and keep a record of your findings so that you can refer back to.
cheers

I have owned an AZ Mount Pro for about five years - it was one of the best and lightest portable mounts available before the new wave mounts hit the market. I have found it robust and reliable and my preferred mount for planetary work with my Celestron 9.25. 

 

Graham is absolutely spot-on with his leveling technique - my bubble level is  a bit off, but equalizing its position as it rotates seems to work.  The cover over the GPS unit on top is annoyingly not flat, so you can't put any leveling device there unless you replace it with, for example, a flat piece of plexiglass.

 

The other major annoyance is the clutch.  Mine is still unmodified and holds OK if all is balanced, but I hear from all other users that the Teflon washer is the way to go - a project for a cloudy night!

 

One other issue to watch out for - I have been controlling the mount with an ASIair controller (using an EQMod cable direct to the RS-232 jack on the mount) and this worked perfectly until the last ZWO firmware update last November.  This update introduced a glitch in the iOS (but not Android!) software that causes mount control to drop out - the AZ Mount pro and a few others were also apparently affected.  ZWO are aware of this and I am assuming there will be an eventual update to rectify this.

As of today, there has been no change to the problem - it still occurs on iOS devices with the latest beta software and firmware. I ran a test this morning and sent a screen shot with note to the developers.

I have been using the AZ pro for a bit now and i consider it my best astro purchase.  Biz is the man in the know about concerning this mount.  I have a short torpedo level that i use to level mine.  I level the tripod, then the adjustment screws. Is it perfect, no, is it close enough, yep.  As far as initial alignment goes, this might be the weakest link as it is almost always off more the one would think, but once you get aligned on the target it is good to go and will drop whatever i am looking for in a medium focal length eyepiece.
