Re: Which Camera?

Woody Schlom
 

Mike,

Flat USB3 cable "high-quality?" That's news to me. Flat means the data pairs aren't twisted. And that means they're much more prone to interference and noise. And none of the flat USB cables I'm familiar with are shielded at all. And again, that means possible noise from interference.

As for my "high-quality" USB3 cables I use the L-com ones with AWG 28/26/24 wires inside. The data pairs are all twisted and the power wires are the #24 ones. The cables are also double-shielded (foil plus braided over that) and have ferrite cores on the ends. Expensive, but very good cables.

Many (most?) USB3 cables use AWG 30 wires, with #28 wire for power if you're lucky. And most consumer-grade USB3 cables don't even give specs. -- so you have no way of knowing the size or type of wires inside, whether they're twisted, or how many shields or of what type they they're using -- if any.

That reminds me....

In 2019 I had a serious problem with my ZWO ASI1600MC Pro hanging-up
and not downloading an image. It even went back to China for an engineer to
check out.

(Nothing was wrong with the camera; the problem turned out to be a USB
webcam I was using to view the observatory was hogging the USB traffic on
the PC, even though it was USB 2, and the '1600 was USB 3. When I
disconnected the webcam, the '1600 worked perfectly.)

BUT, in my extensive email conversation with Chad, the ZWO engineer in
China, he mentioned that many USB 3 cables are of inferior quality, and the
flat cable they provide is the only one they can confirm works with their
cameras. IOW his first suspect was the USB 3 cable to the camera.

Chad also told me that powered USB 3.0 extenders often cause problems,
and he recommended using only a high-quality brand-name extender. I have
a Plugable no. USB3-5M-D: <https://www.ebay.com/itm/264095004596>
(This is an eBay link, but the vendor is Plugable itself.)

Bottom line.... Even though my camera's problem was caused by a USB 2
webcam, I learned a lot about USB 3 cables and active extenders from an
engineer with experience with them.

----------
BTW, I am extremely impressed with ZWO's support in resolving this issue.
Chad was quite knowledgeable and responded to my emails quickly (12-hour
time difference, so I usually had an answer to an 11pm email when I woke up
the next morning).

Chad convinced me to send the '1600 to him (via the dealer), and he
personally performed the tests (including in hot and cold chambers), then
told me the results (nothing wrong). He shipped the camera back to me
directly at no charge.

That's what I know about USB cables and ZWO cameras, and ZWO customer
support.

Re: Meridian Limits files #APCC

Ray Gralak
 

Hi Joseph,

When you load a meridian limits file it will get automatically copied and saved into default.mlm. So, technically the next time APCC starts, it will use default.mlm instead of the original meridian limits file you loaded.

Given the former the most commonly used profile should be named "Default"
and less used profiles can be names to reflect the specific equipment. Correct?
Yes, that is true. Maybe we can make a slight change to the UI to show what the currently loaded meridian limits file name is.

I need to remap the meridian limits to accommodate new equipment. The documentation for APCC-Pro states the
Default.mlm file will be the currently loaded file, which I interpret as every time APCC is started the Default.mlm will
be loaded automatically for the current session. If I create a .mlm file for each telescope/camera combination I have
I'm assuming then that if I change equipment between imaging sessions I will need to open the meridian limits tab
and manually load the profile for that specific equipment. Then after shutting things down the next time APCC-Pro
is started up the Default.mlm will be loaded again. Or will APCC always load the last profile used?

Re: Which Camera?

Jeffc
 

I’ll echo the cable issue, which is fixable , imo.
As for the ZWO driver issue.. if I read the thread correctly, ZWO was working on a fix for the driver problem.

As mentioned previously I’ve been using a QHY268M for a couple months now.
(I’m also using a ZWO ASI174MC on the same computer, and a QHY Polemaster.)

Initially it was nothing but corrupted downloads with the QHY268M. Then I realized I was totally exceeding the 3 meter USB3 limit.

The cable that ships with the QHY268M is so-so ok.. it worked IF it was only used to connect direct to the computer. Hub was a no-go. I replaced it. I’m connecting to a hub (UPBv2), then to the Mach2 USB port then to the computer mounted on the pier so I can use a 1 foot cable to the mount.
Total length on USB is about 6 feet.
Finding good cables is a bit difficult. Ppl on ap-ug / ap-gto have mentioned L-Com cables are very good and work with these cameras; I’m using random USB3 cables from Amazon and a local computer store , and they are hit-or-miss tho I have a combo that seems to work. That said, I might get some “right angle” cables from L-Com.

As a side note , I’m using the Ascom driver with SGP. Btw I’m powering the camera (and other 12v accessories) with a Yeti 1500x “solar generator” battery power supply which has a regulated 30A 12v output.

I’ve also had no problems with the QHY filter wheel. My only complaint is the RJ45 power/command port and cable is a bit difficult to remove but I think I’ve got the hang of it.

I read the thread, and found a several interesting points, but no one mentioned all three together, so it sounds like kit-and-miss to me. I have no idea about the poster who mentioned powering the camera from 12 volts.

I have an ASI-1600MC Pro, recently had a problem with MaxIm not downloading an image -- it just hung up.

The three CN points mentioned:

* USB speed set to minimum of 40
* USB 2 vs USB 3 cable
* ZWO native driver vs. ASCOM

In my setup, I use the ASCOM driver and a USB 3.0 cable at the end of a 15-foot powered USB 3.0 extender. This has worked perfectly for a long time. Then I added an ASI-120M guide camera with another powered USB 3.0 extender, and the ASCOM driver.

Somehow I must have screwed-up the '1600 main camera settings, because that's when I experienced the download problem. I went into the ASCOM driver properties and, sure enough, the USB speed was set mid-range, not at 40. When I set it to 40, the '1600 worked perfectly again.

So, summary;

* USB 3.0 cable
* ASCOM driver
* USB speed set to 40

Hope this helps, at least a bit.

cytan- just a FYI

I bought both the 2600MM and MC when they first became available and have had no issues whatsoever using them with SharpCap.  They also connect with NINA but I have not used NINA extensively.  The CN post seems odd as folks seem to be describing multiple random issues.

Re: Is APCC Pro .17 the latest available? #APCC

Ray Gralak
 

Headed out to the desert without internet for several days and wanted to get everything up to date before I do so. Is
there a beta or developer snapshot of a newer version than 1.8.8.17 I can download?

Also how close are you to 1.9 with ASTAP support? Thanks
No, we have not made any public beta or developer snapshots.

ASTAP is completely supported and tested in 1.9 but there are last-minute documentation updates and release management details being worked on.

BTW, why would you want to use beta software from any manufacturer at a dark site? That seems like a risky decision that could cost you imaging time if something goes wrong.
