PLEASE NOTE: There is no Android version of this, even though there are look alikes. The Pro version is $1.99, not $2.99 as stated in Part 1. Polar Scope Align Pro is an excellent app to get the position of Polaris. This is a demo of the daytime polar alignment routine. I show how to place the device on the mount and roughly align the mount for nighttime use. It seems accurate enough to get you...

Just a quick tip on how to plug all the unused ports on the mount. It'd probably never be a problem but why risk plugging something into the wrong port or having a mosquito get stuck in there?

Powering on the mount, updating the RA board firmware and some basic computer control via iOptron Commander
I had an older Ultima C-11 SCT, it weighed 30 lb on my bathroom scale, so the 10 " would be somewhat lighter, I think? Mounted the C-11 on my Vixen GP D a few times, it was an over kill on the Vixen mount rated for 25 lb, but careful balancing I was able to use it for visual observation.
Bom dia, caro desenvolvedor o Polar Scope Align Pro pode ser utilizado para fazer alinhamento de montagem no hemisfério sul, ou existe um app especifico para esta área?
Knock Knock! anybody home?
Thanks for the Video, GREAT JOB! I have a question - I am confused on one thing, and maybe someone else my answer this question too. I just bought the Skyguider Pro and haven't gotten a chance to use it yet. So. I have been watching YT Vids on setting it up; but there is contradictory or incomplete information on what it is you are aligning to. Does the North Star go in the CENTER of the scope, or does it go on the inner ring (NH) at the position where your app (whichever one you are using) shows the North Star? The way the instructions read, and shows, is you place the North Star on the inner ring in the same location as whatever app you are using shows the North Star to be. I have seen a few videos using this method. I AM CONFUSED!
I appreciate this a ton...even 4 years later, and I'm sure many years to come it'll help others and probably preserve a few CEM60 worms, haha. I really needed to understand the inner working of the clutch mechanism to keep my mind at ease. When I know how it works, I know that I am using it correctly and not damaging it.
Glad it helped!!!!
Well explained. Thanks for putting this together. Now I want to rush to the campsite and set up to try it out.
This method seems like it would be adding backlash in the gears between the coarse and fine focus knobs too.
i go g11 every time
Hi Astro Jeff, if money was no object with these mounts, which one would you now choose? Cheers!
If money were no object I'd look at the Astro Physics or Paramounts, however, I think the difference in quality is narrowing as time goes by. Software can do a lot now to make up for flaws in tracking and guiding in midrange mounts. Drivers are a lot more stable today too. There aren't as many issues with goto, especially if you are plate solving then slewing. So as long as you don't overload the mount and have decent balance and alignment I think most mounts are capable of amazing work. I'm still super happy with the CEM60 and use it regularly as time permits.
Do I need to remove the phone case? It is just a normal plastic one.
Four years on, how is your mount doing? Do you think you made the right choice?
Yeah! I use it regularly, now with a 130mm Triplet, mono camera, filterwheel etc. Works great, guides between .5-.75 RMS. One issue with a control board but iOptron sent a replacement and no other issues. Pretty happy with it.
A couple of words for Losmandy mounts. One of the most important parameter is the periodic error, especially the rate of change of periodic error. Losmandy’s periodic error is very good and smooth. And you can press the touch buttons on the controller in gloves.
the first thing to evaluate before all the rest are the dimensions, the number of teeth, and the material (alluminium or bronze) of the two worm gears.
Man my compass never seems to work well
So where do you initially get the Position and Target position numbers?
You normally position the focus tube all the way in and then zero it in the software to for the initial setup. Then you can pick any arbitrary position as long as there's enough room to move in and out to check the backlash.
@@_Astrovert During initial setup, how do you determine the max distance limit for the EAF so you don't hurt the EAF or your focuser? I knew my focus tube had a length of 42mm on the shaft so I extended to that, and used the current position as the max in the driver settings. Sound right?
@@ScottCanoni Yes, that seems like it would work as long as the focus position number doesn't go negative when rolling it in as far as it will go. Ideally you'd want it at position zero when all the way in and at whatever the max number when all the way out.
Nube question. Just got a CEM40. Do you run it with the RA and DEC knobs locked?
The scope doesn't throw off the app? No interference?
What's the margin of error?
This helped me alot, thanks, keeping the legs in is KEY. you might hate those tighteners but what they replaced them with is way worse.
Great way to check and correct backlash in daytime. I think that this method is some kind of rough backlash compensation setting but is easier and you dont waste night time doing the backlash analisis. Kudos!!! And thanks. I will try this today
sorry but 15-20 max payload difference from the cgx to the g11???really?pathetic
Finally, someone who can actually manage cables. Great job.
Hello Jeff, I hate those half-turn screws as well. I do not remember where I first saw a better system, but these "Bike Seat Clamp, M6 × 65mm Bicycle Binder Clamp Bolt Seat Post Quick Release, Pack of 10" (amazon) works great. When I purchased them they were offered in 3 colors. I hope this helps.
Fantastic idea! Thanks!!!!
@@_Astrovert Glad to be able to help. I purchased red ones for my two tri-pier and Tri-pier 360. kevin
What a great idea !
Top job cheers.
Made in China was something I couldn’t stomach any longer. My Losmandy is 100% made in USA 🇺🇸
Too bad they cancelled production and moved to the 70.
I wish they would move the CEM40 to a CEM50. Might be a sweet spot for a lot of people.
Fantastic video :)
Hay Astro Jeff...do I need to be in a specifi place in the sky (ie. near meridian and equator) to run the guiding asistant?
I normally do mine near the target I'll be working on. I think the results would be better since the atmosphere, declination, refraction, etc would all be the same as where you're imaging.
I know this video is pretty old but something i noticed about ppec was that if you turn off ppec, calibrate phd2, record pec, calibrate phd2 again then they dont seem to fight each other. Dont know if thats a thing or not but semt to work for me.
Jeff. Thank you very much. I was struggling reading a lot but going anywhere. You made it easy for me. Thanks.
Nice little presentation...very helpful
You though it was off but did you notice when you were done your cross hairs were close to where Polaris was supposed to be. Instead of aligning to the center. Align the cross hairs to where Polaris is supposed to be then look.
Exactly. I noticed that too. The two rings are Southern (outer ring) and Northern (inner ring) hem.
With my iOptron GEM45 I always tighten the saddle clamps using an Allen/Hex key. You can get it nice and tight. I always put on the end stops just to make sure.
Great tip!!
Works great! Did it, then went inside and opened Stellarium on my PC, which is linked to my HEQ5 Pro mount, and it was bang on. Tonight will be the true test.
If you watch the video from Celestron for the CGX they specifically talk about how the weight capacity of 55 pounds is actually pretty conservative and that it’s built to handle every ounce of that and they built it to actually handle a little bit more in case people push it the 50% rule for most of these systems isn’t really necessary manufacturers don’t typically double the realistic capacity it would only lead to poor performance and poor brand recognition
hi mate, could you share PHD and SGP meridian flip parameters? I use the same mount :)
I'm not sure if this has helped me, my PHD2 declination backlash, always returns something like >8000 - cant be measured. I use CPWI STARSENSE for alignment, followed by ASPA, and do the ASPA 3 times. The mount is balanced ( as far as I can tell (CGX with C8, including all gear)). My guide graph is around .5 to .75, yet, it is jagged, nothing smooth about it whatsoever
There may be something mechanical going on in your mount. Try looking through a moderately high power eyepiece at a single star, then move the mount in one direction in RA for a few seconds using the hand controller, then reverse the direction and see if there's a delay before the star starts moving again. If there is, this is backlash and the gears need to be tightened up a bit. (make sure there is no backlash compensation turned on in the controller)
@@_Astrovert Thanks. I will give it a go. I may put it in for warranty, it is only 6 months old
This isn't very accurate because it relies on wonky magnetometers in phones, and it also sits on metal mount. It's for very rough estimates only.
Hi Jeff, I noticed you have a ring around the focus knob. Curious as to what that is?
It's a "Fine Focus Knob" from scopestuff.com ($29). To be honest it doesn't make that much of a difference. There are also DIY things you can make for it too.
I have tried with my ipad and my iphone and its always way off. I have put on a wood stick away from the metal. Nit sure what else to do. I woukd like to get at least close for shooting the sun during the daytime.
I would like to know wether this app. is usable in the Southern Hemisfere. Thanks
Very useful, thank you.
is an Android equivalent (alternative) available?
Question: I have an obstruction at my house to Polaris, is this app something I can use to get a good polar alignment when I can not see Polairs?
Yes, but it will only get you in the ball park. You'll still need to drift align to get a better polar alignment.
The Celestron All Sky Polar Alignment is actually very effective. Three iterations took me about 45 minutes and my CGEM DX mount was under 10 arcseconds away from the pole in RA and Dec. This is one of the best features of Celestron mounts. Great comparison matrix!
What app do you suggest I use for android? I have an iOptron Skyguider Pro
Hi Andy. Thank you for you nice job and explanation. My guiding setup is: Celestron 9x50mm + ZWO ASI 120mini camera. Mount thanks to SharpCap is facing the North Pole with the status Good. Unfortunately graph on phd especially RA is disaster. Main Setup is NEWTON 200/800 + ZWO ASI 294 MC pro camera on NEQ6 mount. Whad do you think I need bigger guide scope or your the method shown in the video will also work with OAG?. Greeting from Poland :)
i need to set the latitude 51 degrees but is it to high for my meade teleschope it is ridiglous but true so no polaris . the screw is just to short .
That was awesome!!! Thanks... I am a first time buyer. Did the upgrades to the Atlas ll make a big difference in your opinion? Thanks in advance
