Note on this issue: A suggestion from another forum seems to have found the problem but I'm not sure. It was suggested that after 3 hours my power tank was drained enough to inhibit the operation of the cooler. I attached my second (smaller) power tank and it seems to be working now. Of course the camera sat for awhile before I was given the idea that power was the issue and decided to try a test with a new power source. If anyone has any additional information or suggestion for me they would be appreciated. Original issue is below:
HELP PLEASE! ASI294 MC Pro Stopped cooling Also have an image saving issue. I'll try to give as much detail as I can:
Using APT with an ASI294 MC Pro - CAMERA IS NEW
Cooler is powered by a Celestron Powertank 17 fully charged connected using an Orion DC cable w/Auto Lighter Plug
Connecting via ASCOM ASI Camera 1 setting
Image Type RAW 16
USB limit 40
The camera is plugged directly into the laptop NOT a USB hub. I believe all my laptops USB ports are USB 2.0
No other software (such as PHD2) was running.
No other cameras attached.
Trying to create a dark library.
Cooling to -5C from room temp of around 25-30C
Camera and cooler were working fine for a couple of hours but I then ran into a snag:
I got a time-out message from APT saying "Still waiting image from the camera - 30s" also -
The cooling stopped working. (Red light indicating power is still on. Fan is still spinning.)
I'm also noticing that the laptop is making the chime noise it makes when something is unplugged or plugged in.
I tried connecting to the camera just using APT's ZWO camera setting with the same results.
Black level and USB speed settings were left blank.
Disconnecting and reconnecting everything seems to fix the problem only for a minute then I'm right back into the same problem. Changing USB ports does not help.
I tried using ZWO's "ASI Studio" and I did not seem to have any problems capturing images but the cooler didn't seem to be working. (Power was = 100%)
I tried using Sharpcap and did not seem to be able to do anything but I'm very unfamiliar with that software.
I went back to APT and tried doing 10 lights exposures of 30 sec each with no power to the cooler. Those went ok. I then connected the cooler. The cooler cooled the camera down to 23.2C then stopped.
Cooling Aid settings are
Timeout 120 (also tried timeout 300)
Disconnected the cooler and ran another set of 10 30 sec light subs. These went ok. Tried set of 10 10 sec darks without cooler. This also went ok.
I tried reinstalling the ASCOM drivers from the ASI site, restarted the laptop, restarted APT. Camera cooled from around 30C to 25.3C then stopped cooling (Red light indicating power is still on. Fan is still spinning.) I again started hearing the plugged/unplugged chimes from the laptop.
So right now this seems to be some issue with the cooling. Is the camera defective?
While I'm not computer illiterate, I'm not highly technical. I'd appreciate any help or advice but please put it into simple straightforward terms.

Just wondering what other people have experienced with this camera. I'm using a MacBook Pro, and want to use this camera with my Celestron 8SE. Primarily interested in the planets and the moon, but some deep sky images would be great if it's up to it.
It seems to be out of stock every where, but at $249 is about what I can afford to spend (no income at the moment). All of the research I've been able to do on this camera indicates it should work well with my set up.
I'm just curious if you have had any issues or problems. Thanks in advance!

Restoring a Backup on a Mac
Something else I came across and a chap called Terry on Facebook had a solution.
Again, you might already know this, but just in case.
You buy a new ASIAIR Pro, you are pretty much advised that one of the first things you should do, is to create a backup of your software(includes your license key) from the supplied SD card.
And one of the common methods suggested for Mac users is to use the “Apple Pi Baker” program/application.
So, I used the application to create my backup and saved it in a safe place, in fact I made two copies(belt and braces).
Then, yesterday, I thought I should really try to restore one of these backups to make sure they actually work, else what is the point of having a backup for that rainy day.
And actually, I will keep the original safe and use my copy going forward.
So, I inserted a new blank SD card(Fat32) and started the restore process, letting it run its course.
Once it had finished, I did a quick eye ball to compare the copy to the original and all the files appeared to be there.
I then plugged the restored SD card back into the ASIAIR Pro, but the device would not start/boot up!
Just in case, I then reformatted another SD card and tried that one, but still no good.
I then created another backup from the original SD card(so all in all I had img and zip versions) and tried to restore them, the same result, fail.
On further investigation, it looks like this is fairly common.
Terry on ASIAIR Facebook group suggested downloading the file from the ZWO website, but then using your own License file.
I then used the ASIAIR PRO link above(from the “How_to_Restore_ASIAIR_OS.pdf” on line doc) to get the file.
First, keeping a copy of my zwoair_license safe of course(still on the original SD card).
The file is pretty large, unzips to about 31 GB and takes a while to download(9GB zipped) even on cable.
I then restored(using Apple Pi Baker) this new downloaded file to my new SD card and once it had completed, I then overwrote(replaced) the
existing “zwoair_license” file with my original(my unique supplied copy).
Next, I then inserted the new copied/restored SD card into the ASIAIR Pro and it started.
Finally, I then connected via the ASIAIR app using my IPhone and was prompted to update the firmware to the latest version which I did.
Bingo all good, the original SD card supplied by ZWO stored in a safe place and I am now using this copy going forward.
