Just stumbled on this. Stella, upcoming Ekos/StellarMate Astrophotography digital assistant.
https://www.stellarmate.com/help/Stella.html
This might get me back to revisit my old RPi4 StellarMate again. Video below.
If it turns out to be properly implemented, it might finally become competition for ZWO ASIAIR
Apparently announced in April, did quick search on mobile phone but oddly did not find other posts here on SGL.

Improved for 2024:
New USB-C & DC 12v output ports on the mount saddle for improved cable management
New Bluetooth compatibility for improved connectivity
New base design eliminates azimuth locking knobs
Improved tracking with higher load angles & heavier payloads
Periodic error reduced from ±20 down to ±10 arcseconds- 1

New Features
- Added an AI model for denoising linear images
- Redesigned the user interface for incorporating the denoising model
-
Extended GraXpert's cli interface with a denoising command. Run
graxpert -h
from a terminal to view the cli documentation - For gpu acceleration during denoising, please note: on Windows, we rely on DirectML which requires a DirectX 12 compatible graphics card. On Linux, we rely on CUDA 12 and libcudnn8. On macOS, we rely on CoreML
- Repackaged AI models in .onnx format. This simplifies to provide GPU acceleration on different hardware platforms for us. Thanks a lot to Riccardo for his pull requests!

Looks like it.

Nope, ASCOM / ALPACA connection via WiFi is available.
See video with Nico Carver and Ben in Edit 4 below:

Nico confirms it is ASI AIR Mini hardware inside and 2600MC Duo is externally controllable via ASCOM / Alpaca over WiFi.

Nope, but this may help.

I'm not sure how the guider behaves if you want to use a dual-narrowband filter.
Works just fine.

Interesting new development.
The tease started as April Fools Day joke.
But now appears to be introduced at NEAF. Below was shared in one of AP imaging groups.
Nico posted this.
It was a matter of time. I like the concept, if it gets to work properly (had to RMA my 2600MC DUO). I wonder how much memory will it have 32 GB or 256 GB. What do you think?Edit 1: From: https://www.cloudynights.com/topic/919191-new-camera-zwo-asi2600mc-air/

Same here. With seldom clear nights that I am able to put everything else aside, take my gear and drive to the dark site. I have no patience for troubleshooting.

initial testing in the house gave a reading of approximately 10degrees below ambient temp
Appears to be in line with my results. I used off the shelf smart phone Peltier cooler on ASI585MC. Best results will be during the summer months.

Had similar issues with corner stars on full frame with my scope.
Troubleshooting was cumbersome and took forever given my limited availability, clear nights for last six months.
Adding individual 1mm, 0.5mm and / or 0.3 mm rings (refers to unscrewing the camera adding ring and reattaching the camera), refocusing (on full frame), adding more rings, overshooting, correcting, overcorrecting. Add freezing temps and loosing clear nights on this just adds to the overall frustration.
I bought Precise Tuning M54 Artesky Ring
Unfortunately, it rotated field of view so it was hard to make like for like comparison without spending even more time on rotating the focuser. But then light at the end of the tunnel just as I wanted to give up...

As mentioned still some fine adjustments to be done, but much better and so much faster.

Perhaps a less destructive middle ground solution with smartphone coolers.

only way you can rule out the asiair as being at fault is to try it on a laptop.
Well, was not planning on it but did it anyway...
With OEM cable:
After market cable:
Result is that the guide cam connects fine and takes exposures without issues. ASI app crashes when ASI2600MC DUO is activated in app. Video below:
15 hours ago, dciobota said:When I contacted zwo for advice through their forum initially one of the things they had me test was using windows and the asiair studio app. So they may require the same of your vendor before approving a replacement or fix. I would do that if at all possible before returning it.
With cold camera from outside, unfortunately the result is the same as seen above. After it worms up for some five to ten minutes it connects, sometimes.
15 hours ago, dciobota said:In which case I would try to get a variable output power supply to feed the duo and fiddle with the voltage between 12v and 13v to see if there is a sweet spot where it works consistently.
Have it, went down to 12.14V and the result is the same. The voltages tested are within the spec and should all work.
15 hours ago, dciobota said:Do you have a way to monitor power draw? With the main camera disconnected you should be drawing 10w or less. With the cooler full on my old asi2600mc would draw around 26w or so.
Ranges between 5W and 7W.
And just for the kicks tested both ASIAIRs Plus again...
AA+ v3.0:
AA+ v3.3:
Long story short, contacted the distributor and requested RMA. They accepted based on evidence provided, sent return label and wished me good luck and lots of patience given it is New Year at ZWO.
Thank you for your inputs. Will keep you posted as the situation develops (in few moths probably)... -
Hi all,
It appears I have an unusual connection issue with ZWO ASI2600 DUO and wanted to check if I am doing something wrong before I go for RMA to distributor. Important to note that all cables, power supplies and both ASIAIR Plus work flawlessly with my other cameras, namely ZWO ASI6200MC PRO, ZWO ASI585 and ZWO120MM-S. Did not try to connect to laptop as I am mobile imager and do not use laptop for acquisition.
The main camera although recognised does not connect to the ZWO ASIAIR Plus, while the guide camera connects fine and works every time. As I am sure you are aware ASI2600MC DUO uses same data cable for both cameras. The main camera rarely connects indoors at room temperature, but never outdoors at cold temperature.
Guide camera works and guides just fine. Misshaped stars on DUO are normal due to guide sensor position and light circle of WO REDCAT 51.
I have tried using flat and red round ZWO OEM as well as after market USB 3.0 data cables,
Nothing else was connected to AA+
Different power supplies such as two different direct AC grid to 12V transformers (12V, 6.5A), EcoFlow Delta 2 (12V, 3A and 10A) outputs, and two different ASIAIRs Plus 32 GB and 256 GB model (always directly connected to power supply not through ASIAIR Plus), but the problem persists.
Few screenshots to demonstrate the issue in detail below:
Voltage provided is always separate for AA+ and 2600MC Duo ranging from 12.77V to 13.28V with 6.5A from AC adapter to 3A - 10A from ECOFLOW Delta 2.
Connection issue persists with latest stabile version:
As well as with latest beta.
To repeat all of the above works flawlessly with my other ZWO cameras. Confusing part is that sometimes but quite rarely it DOES connect.
Have I missed something? Should I try something else before returning to dealer? My fear is that distributor will test indoors at room temp and conclude that the product is fine refusing RMA.
Thank you for your input.
Zwo 178mm. Is it worth trying to cool it?

There are smartphone coolers without led lights. I tested two and you can find details in the post below.
TLDR: You can expect up to 10'C lower temp compared to ambient.
