I have no clue. The flattener came without any documentation, and there are no markings on the flattener anywhere. :(

Based on the picture, I would say that you probably do need more extension tubes and you may also want to check the back focus requirement like Mick mentioned. I have a MC that I have to use an 8cm extension along with my other adapters. One other thing to check is what focal lengths your flattener works with. For example, my flattener will only work with scopes with a focal length of 500mm to 1000mm, so I can't use it with my MC as it's focal length is 1900mm. Lastly, just for focusing, set your camera to it's max shutter time (mine is 30 sec) and ISO to 400-1600.

Good luck and clear skies.

Paul, I forgot to mention on my ES 80, I have to use an additional 2 inch extension tube plus the .8x focal reducer (looks similar to your field flattener), with my crop sensor DX5300, and focus no problem. I see on the ES website your scope comes with 2 extension tubes. Mine did also. I believe that is your issue.

Yes paul.  The polar scope switch assembly is also a battery holder.  It unscrews.

Polar scope illuminator not working #EXOS2

Paul Meesters
 

Hi,

Where is the polar scope illuminator getting it's power from ?
When I power on the PMC8, the illuminator does not light up when turned in the "On" position.
Is there a battery involved ? I never used the illuminator before.. How do I get it working ??



Thanks,
Paul

Hello,
Have you used your set up during the day, focused on a distant object with a prominent point ( top of flagpole), and ensured you are in focus?

Hi,

I have a field-flattener attached, and a T2 adaptor for my Sony A7iii. Whatever I do with the focusing in-or-out, I never get any stars in the display of my camera. 
It's not for using wrong camerasettings. I used a 15 seconds shuttertime at 32000  ISO.. no stars at all (and no, I did not forget the lens cap)

I'm not sure what I need to do to get a picture.. Do I need more extender tubes ? It's already sticking out more then I like, since the T2 adapter and the field flattener are very big...

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

 


Re: EXOS-2 PMC-8 Autoguiding noobie question. #pmc-eight

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 ;)



Re: EXOS-2 PMC-8 Autoguiding noobie question. #pmc-eight

Ming
 

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.

Subject: [Special] [ascomhelp] Important Update for People Using Platform 6.

 

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.


Re: Goto issues #iEXOS-100

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
