New iexos 100 Dec Slop #iEXOS-100 #VIDEO

Don <donsinger@...>
 

I just received a brand new iexos 100 mount after several months on order. After assembling it and having both the RA and DEC clutches engaged, I noticed that the Dec axis has a lot of slop. When I gently press against the counterweight bar, there is approximately 1/8" of very loose movement in both directions (total of 1/4" movement).

The only other mount I have had that had such a problem was an iOptron CEM-25p and I could never get it to guide acceptably, even after several trips back to iOptron. I purchased the iexos-100 for astrophotography with light gear (WO ZS-61).

I assume that the play in my new iexos-100 is not a 'feature' - is there any way to fix it or does the mount have to go back to the dealer for an exchange. I would rather fix it myself than send it back and have to wait another few months for a new one.

Input appreciated!

Thanks,
Don/KF7DS

Finally I went with ZWO 60mm f/4.6 Guiding Scope and ZWO ASI290 Mini. Everything went smooth with INDI/Kstar/PHD2 on OpenSUSE Tumbleweed Linux. I even managed to get some first photos!
My current telescope is Bresser NT-203s. As you can see on the photos, coma corrector is still missing. And I still need to do some work with mounting everything properly ;)
... and autofocuser is obviously needed ;)

ToupTek specs show they are supported by INDI, so the usual INDI/Kstar/PHD2 combo on Linux should work fine.

But honestly choosing this Bresser 90/500 for guiding is a bit unusual. If your imaging scope is between 80 and 120mm, a 50-60mm guidescope along with ASI120MM or ASI290MM would have been enough. This way you avoid putting unnecessary load onto the mount. If you plan to use long focal length scopes (e.g. SCT), an OAG will not only be more accurate but also less load compared to the Bresser.

Hi all,

We have just posted a release candidate for ASCOM Platform 6.5 Service Pack 1: https://github.com/ASCOMInitiative/ASCOMPlatform/releases. This addresses a serious bug in the Transform component that was introduced in the initial Platform 6.5 release and which is known to have manifested in the Astro-Physics driver and in the AstroTortilla application. Other drivers and applications may also have been impacted.

If you have installed the initial Platform 6.5 release, we strongly advise you to update to the service pack 1 release candidate.

If you have already installed an early beta version of the service pack 1 release, we also advise you to update to the release candidate because it includes further fixes and supports clean reversion to Platform 6.4 SP1 if required.

In addition to fixing the Transform bug, service pack 1 includes several Device Hub and installer fixes. The Platform releases link above contains a full list of changes.

The Platform and Developer Components installers have been submitted to VirusTotal and are passed by all major anti-virus scanners. SHA1 and SHA256 checksums are listed immediately above the installer executables in the releases link above.

Best wishes, Peter

Here's my M31.  30X75 seconds at  ISO 800 through my William Optics Z61 (360mm/f5.9) guided by PHD2 with a QHY monochrome camera and mini guide scope. With sharpcap for [olar aligning and astrotortilla for plate solving the setup and aiming were easy.  This was done from my suburban back yard with a fairly clear sky.


Post-processing was done with Siril scripts which is by far the easiest option i've found.


Choice of tripods for those who would like to increase the payload on their iEXOS-100 #iEXOS-100

Ming
 

For those who want to replace the stock 1.25" tripod in order to increase the payload limit on their iEXOS-100, you have two options:

ST2/3 tripod:
The ES Medium/Heavy Duty tripods are not available in the EU. Here is what I did. I approached my local Bresser dealer (Bresser UK) and asked them for the Bresser version of the ES ST2 tripod. They got in touch with Bresser headoffice in Germany and my ST2 tripod was delivered by UPS 5 days later. It costed me £135.

Skywatcher 1.75" EQ5 tripod:
Out of curiosity I tried my iEXOS-100 + Fine AZ adjuster on my SW 1.75" tripod that I normally use with my HEQ5. The combo worked flawlessly. So for those who can't get hold of the ST2/3 tripods, buy a SW EQ5 tripod instead.

Re: Goto issues #iEXOS-100

Apre,

You are not alone! I have used the bubble level to polar align and a spirit level. They show different results so, something has to be improved on there. I align my polar alignment scope with the pole and can even get to see the north star through the narrow tube yet, when I slew to my first alignment star, it's way off. I adjust, set and move onto alignment star 2, have to adjust again but then when I slew to mt target, it's way off.

Except, 'way off' is too strong'. I looks a long way off but isn't in reality. Every time I attempt this, I get better, and more accurate. It is a scintific instrument and using it has to be learned. My wife who works in a lab told me of a newly graduated scientist who couldn't seethe cells under a microscope. Two days into the job he was despondent and he was convinced that he would never be able to use the microscope properly. Third day into the job and he had success.

There are many many new skills to learn here. Practice makes perfect. I haven't managed it yet but, I get a little bit more accurate every time.

Clever thought Jennifer -  I did not think of that and it had thrown me  the first time I tried. the mount. The default latitude is  zero which the mount regards as  the southern hemisphere and tracked backwards!  (I once did an imaging session with the tracker set to South - lovely star trails!)
Cheers,

Ian

Hi Apre, sounds as though you are setting up correctly. A couple of possibilities, when you say the Polar home position presumably your mount is pointing North or close to it, also are you satisfied with your 12v supply?

Re: Goto issues #iEXOS-100

Hello, I levelled the tripod using the built in bubble level and position it at polar home, however this is only rough as I dont have view of polaris so I set my mount to my latitude and just try and make sure both the dec and ra are at 0 like instructed in the supplied manual. After this, I power on my mount and connect my iPad to it; once I do that the motors begin to make a noise. I then press reset alignment and after that I press the 2 or 3 star alignment buttons. Once I have done this the mount moves to close to the target star, I use an app on my phone to confirm the star I am looking at is the correct one and then use the left/right/up/down buttons in the app to position the target star in the centre of my screen on my dslr. Once I have centered it I press enter and repeat on the other 1/2 stars. Finally, once the star alignment is complete I go to the catalog and select the object I want to go to and press the slew to object button.
Hope this a good enough explanation,
Thanks,
S

Can you provide some more information step by step please to help better diagnosis the actually problem.

To leveling the tripod to how your trying to control the mount either with the tablet or computer. 


Re: Goto issues #iEXOS-100

Apre
 

Yes, the telescope was in the polar home position before I powered up the telescope.
Also, my mount doesn't seem to track, I manually moved to M45 and there was lots if star trailing at 200mm on a aps-c dslr with 30s exposures.

Re: Goto issues #iEXOS-100

Ian Morison
 

Hi S,
   Was the telescope in the polar home position (ie., pointing towards the North Celestial Pole)  before powering up the mount ?   I made the mistake of not doing this once when I had just got my mount.
If the mount is coupled to your tablet or laptop then after a manual move it will track at sidereal rate. 

Cheers,

Ian

Hello, I have recently got a iEXOS-100. After star aligning the mount I selected andromeda and pressed the slew to object button and it began to move; however it slewed to the totally wrong place and i am not sure what I am doing wrong.
Also, how do can i make it track an object that i manually move to.
Finally can someone show me some good tutorials for the mount as I cant find many.

Thanks all,

These cameras, as well as the new cameras from Meade and Orion, are made by ToupTek.  They list Linux in the specs. 


The ToupTek cameras are also supported by INDI.

However, I unfortunately I don’t have any direct experience with this particular camera to definitively say it works with Linux.
