I agree, I've been having good, stable performance using ASCOM over a serial connection.
I'm curious do you use ASCOM over the wired serial interface or over the wifi connection?

...just a small rant.... I promise.

/Rant
It seems to me that one of the most frequent issues people face and post about on these forums has to do with the tablet experience.  Which tablet should people get, where does the database go, why is this different from that.  I want to give a plug to plain old PC and ASCOM.

Yesterday I rebuilt my IEXOS 100 rig on an old laptop because I am dedicating my Intel NUC to my other rig.  Start to finish I had the laptop installed and controlling the mount from APT including plate-solving in about 2 hours including re-installing Windows 10.  The laptop had Home edition and you can't remote control "home" so I installed "pro".  Installation of Windows, ASCOM platform, drivers, APT, ASPS and SharpCap.  

To those struggling with tablets....give ASCOM a try.  It's tried and proven and not that scary.

Hi Andres,
I use the Bresser 2,0 Kg counterweights for EXOS 2. They are white and have exactly the same shape and look.

Done, it's very easy to give a company with this amount of customer support a 5 star review.

Hi Andrea, welcome to the forum. I realize that it is a bit quirky to not have a pull-down for the different legacy Solar and Lunar rates, but consider the following. The Solar rate is not significantly different from the Sidereal rate as the Sun only lags the stars by 4 minutes in RA in 24 hours. 4 minutes in RA is equal to a 1 degree drift in angular motion per day, or only 2.5 arc-minutes per hour. This rate is not significant when observing the sun over a 10 to 15 minute period at a time and would only result in a drift of 25 arc-seconds in a 10 minute period, hardly noticeable in an eyepiece. This is not significant when doing video imaging of the sun either as you would typically only record a video for maybe 2 -3 minutes at a time. The other significant factor is that even if you corrected the RA tracking rate to the Solar rate, the sun would drift in Declination due to the difference between the ecliptic and equatorial planes. 

It is for this reason that I always suggest to our customers that going to the trouble of changing the tracking rate in ExploreStars is not really necessary for visually observing the sun. We do include a pull-down selection in the PMC-Eight ASCOM driver for Sidereal, Solar, Lunar, and King rates because when doing high-resolution imaging it may be needed, although again, there is no real issue if you do not use those rates.  I think that having these rates is more of a legacy issue and this feature has always been included in tracking mounts since the 1960's.

Re: Questions on my new PMC-8 #EXOS2

Andrea B:

1.  SkySafari.  Where did you see that?  I was not aware SF supported the 
pmc8 natively.  I have posted the method for using SkySafari so long as you are using ASCOM wired connection to the mount.  What you do in that case is load WiFiScope onto your PC.  It connects via Poth to the mount.  You load SF on your iPhone or Android.  I believe you need the Pro version to include telescope control.  I have 6+pro on my iphone, and I think that is needed.  I don't believe 5 has what you need.  

As the PC is connected to the mount via serial cable, the PC can be attached to a LAN router.  Make sure the wireless phone is also connected to that router...suggest you use the device in airplane mode to prevent broadband confusion.  You will setup the SF telescope control per the instructions in WiFiScope.  Basically you select the scope to be a Meade Classic (right, that's just how they did it) and make sure the IP Port number is correct for WiFiScope.

I am assuming you are familiar with ASCOM etc, and this makes sense to you.  If not we can discuss further.

What the SkySafari does is send commands to the WiFiScope that are correct for a direct connection a Meade scope using the Meade classic command set.  WiFiScope serves as an intermediary which translates the Meade commands into ASCOM compliant method calls through POTH.  POTH then will send these through to the ES ASCOM driver.  It all works swimmingly well.  You can also run Stellarium on the PC in concert with SF on the phone and use which ever you need at the time.  Search the forum for how to setup Stellarium.  If you can't find it, we can discuss.

As for the rate, i believe that is correct.  Jerry published the corresponding values for the rates and i believe they are in the PMC8 Programmers Reference Manual.  Seems to me the Solar rate was something like 45.  What version of Explorestars are you using?  I don't believe any of them set the rates to solar for you.

Wes.

More on you other questions in a bit but as to the weight.

I bought an ioptron 8605 counterweight got my ETX 90.  I expect it will work fine for the Lundt.  As I remember it is about 5# or so.

Questions on my new PMC-8 #EXOS2

AndreaB
 

I'm a new owner of an Exos 2gt PMC-8.  I'm very excited and plan to use it with my Lunt 60mm Solar Scope and an Edge HD8.  This is to replace a Celestron Advanced VX that I've had issues with.  I'm realizing I can't balance the Lunt scope with the included counterweights as they're too heavy.  Is there a recommended smaller one I could purchase?  I think about a 5 pound one would work.  

Also, I have the ExploreStars app installed, and I guess the only way to set the tracking from Sidreal to Solar is to actually type in the rate number into the preferences, and not simply selecting it somewhere?

One more question.. I see you can use Sky Safari now.  Do I need Sky Safari 6 plus at the least, or can I use Sky Safari 5?  I already have Sky Safari 5.

It's a beautiful mount and I cant wait to get it outside after it stops raining here!

Thanks everyone for your kind words and continued support. The way I look at it is that we are all in this together, and as the Astronomy Technology Today article said, we don't do this to get rich, that will never happen. The amateur astronomy community generally works together and supports each other along with competing as best we can to develop new and innovative products. We make mistakes like everyone else, but when we do, we want to correct it and make it right.

Clear Skies!!

Re: My best < Your worst - Why doesn't anything work?

 

Burks21,
 
As Dan said, this is a brutal hobby.  A whole lot of things have to go right, in order for those pictures to turn out. 
 
In order for those things to go right, a bunch of T's have to be crossed, and I's dotted.  If you find yourself thinking "It should just work", or "I shouldn't have to...whatever", then that gets in the way of the crossing and dotting, and frustration ensues.  And I know about that, because it was a hump that I had to get over myself. 
 
Visual and Explorestars:  I have no idea why the Android platform requires that the db be installed separately, but that doesn't matter, because for the here and now, it just does.  I don't use it myself, but there are lots of posts here from other folks asking for help with that, and the separate install step for the db in an SD card sounds pretty straightforward. Easy to dig up.  
 
Astrophotography:  You can try unguided for a lark, but guided is simply better and more reliable.  These mounts are designed to be used visually and guided.  The PMC8 controller and its power train are responsive enough, that, given a mount that's adjusted and balanced reasonably well, the Periodic Error(s) on the mechanical side can simply be guided out, just as Jerry says.  And yes, you need a good polar alignment for guiding, but PHD2 can guide around a bit of error.
 
So how do you get there?  By methodically crossing T's and dotting I's.  I'm reading one fer-sure installation problem with Explorestars, and AFAIK, it's easily remedied with a little research.
 
I'm reading a suspected installation issue with APT as well, but can't be sure because I don't use it.  I CAN tell you that it cost me a lot of research and fooling around to get my plate solving working, with AstroTortilla.  Combination of picking the right version of AT, getting the right indexes downloaded, and setting up its parameters properly.  Lots of fiddling about, and sifting good advice from bad on the interweb, but now that I'm past that, it does 'just work'.   Anyway... just be prepared to dig in and work the problems...plenty of happy APT users around, and if they can do it, you can too. 
 
HTH...
 
- Bob

Hello all,
I've done severall attempt to solve this issue.
My last one is to use a Bresser JM-33 2" Pipe Clamp Clamp (12 €), some plastic, a ISA plate (see pict), nuts&bolts.

Some pictures in attachement.
It is solid as a rock, easy to install, move and remove.
