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...

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.

One of the frustrating things about the telescope business is that the industry has to turn on a dime and support a great influx of customers when a significant astronomical event occurs. If you can imagine ramping up a sales rate from several thousand customers to millions of customers in a few short months, then you can understand the problem. Explore Scientific ran into this issue in 2017 when early in the year we decided to support the upcoming Great American Eclipse in August 2017 by selling eclipse glasses.

We ramped up production of our eclipse glasses that were shipped to our headquarters and we enlisted a large team of local volunteers to help package the hundreds of thousands of orders up until the last day before the eclipse. We bought and sold 4 million eclipse glasses if you can imagine. As you can expect, we fell behind as our ordering system buckled under the sheer number of orders. The problem became very acute in the last 2 weeks of the sales as we couldn't keep up with our sales numbers and we basically oversold the number of glasses we had and could ship on time. 

You can imagine customers that ordered online the last couple of weeks when we thought we had glasses left to sell and we found the last week that we had actually oversold and we had no more glasses. The customers became pretty upset and there were hundreds that let us know via our customer support lines, Facebook, and our website. There were a lot of customers that contacted the Better Business Bureau in Arkansas and 19 filed reports against us. This was a low point in our business as our intention was to satisfy all our customers but it wasn't to be. What was even worse is that we had hundreds of customers cancel their order even though their order had been shipped the week before, and they received it in the days after the eclipse.

After the Better Business Bureau contacted us we explained the situation and what we were doing to try to make it right. We made a full-court press to contact all our customers who were negatively affected and spared no expense to try and correct it. After a few months, the BBB saw how we responded and posted a message from president Scott Roberts and decided that although we failed those last few customers we also made a huge effort to make it right and awarded Explore Scientific the Torch Award for Ethics.
https://astronomytechnologytoday.com/2018/09/10/16806/

This was a very pleasant surprise and helped us to shake off the experience a little easier knowing that we did our best to make things right.

Unfortunately, our reviews on the BBB website
https://www.bbb.org/us/ar/springdale/profile/scientific-instruments/explore-scientific-llc-0935-90339490#bbbseal

are very negative and we currently have 1.5 stars out of 5 as a business.  I come to you, our PMC-Eight customers to ask you a favor to go to the BBB website and submit your own opinion of our company and how we do business. The current rating is based on the experience customers had in August 2017. We would like to see more current opinions on the BBB website. You can also see Scott's message on the BBB page linked above.

If you decide to place your opinion of our company on the BBB website, we would be very grateful and thank you for your time.

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

Chris Tardif
 

I use a PC with APT and not tablets so I'm not sure how much this will help so take it for what its worth.

I use ASPS (All sky plate solver).  Configuration is a little finicky but i found that you have to launch the ASPS program first and make sure you can platesolve in that app without APT. You have to make sure you download the correct files for your lens and scope and set the pixel size and focal length in ASPS first.  Once you get it working in the ASPS app then configure ATP.  You also have to tell APT about the focal length otherwise it will not work.

Are you auto-guiding?

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

Dan Kahraman
 

Hi Burks:

1) Polar alignment has to be very accurate. To me it looks like you have a polar alignment issue. Use Sharpcap to help you with this. Initially make sure that Polaris is visible in your reticle scope. If you are using the same location outside, mark that spot. It will make subsequent set ups much easier. You won't have to use your reticle scope then...
2) Do you have the right files downloaded in APT to do platesolving? In addition you have to modify some of the directories. Here is a tutorial on that by Astroquest1 (https://www.youtube.com/watch?v=01sWypHU7vo&t=64s)
3) If you have sag or tilt in your focuser so that your stars are not round, this too will throw off platesolving. Stars have to be round! So no wedge or tilt in your optical train.
4) You have to be quite accurate in determining the focal length, pixel array of your guidescope and guidecamera. This too will make difference in whether plate solving will work.

Don't give up! This is a brutal hobby. Many are ready to help you because we have all experienced your frustrations.

I've had my iExos-100 for nearly 1.5 months and I've yet to taken any better photos than what I was doing by lying the camera on a picnic table and aiming it. Yes, it's that bad. 

1. I decided to get a Amazon Fire 8HD so that I don't have to keep switching programs from APT (because that is working SO well for me, Plate solving? ERROR) and ExploreStars. Guess what? Explorestars is useless on my tablet, works fine on my laptop. I've factory reset the tablet, updated it, used my mother-in-laws, transferred the database to every folder possible (zipped and unzipped, because I can), and so forth. I can move my mount, that's it. No database. No GoTo. Nothing. Ideas? Error is "Could not open database file: /storage/emulated/0/Android/data/com-blahblahblah

2. I'm assuming my polar alignment is causing my inability to take more than a 2.5 sec exposure without star trails? Even last night I had Polaris dead center in my polar alignment hole, couldn't track worth a crap. Set the speed from 1 to 100 going in increments of 5. Just....yeah....I did a better job manually adjusting the mount every couple photos. I don't expect dead nut accuracy but wow. 

3. 100+ photos last night with a Canon T3 and 75-300mm lens. This was the best I got. Can you sense my frustration? I've read articles, I've watched videos, I've swore more than a sailor with syphilis. Someone pops out their iPhone and takes a photo 10x better than this, or whatever that Chinese company is that begins with a H. 



Basically, I'm lost, frustrated, and just looking at anything related to the sky just makes my blood boil at this point.
