Sadly, no...

That makes sense, let us know how it goes.

as it features active cooling
Player One has Active Cooling System (ACS) for uncooled cameras

Alternatively you can use smartphone coolers. They will never be as good as dedicated AP camera cooling but they can help somewhat and do not cost much.

If I was to get a different MFT camera primarily for night time shots such as the Milky Way, which models would produce the least Hot Pixels?
I would prefer to stick with Micro Four Thirds as I have a lot of excellent glass that are f2 or faster.
For MFT Astrophotography, you can check Ben's channel: The Narrowband Channel - YouTube
In the video below he gets deep in new MFT sensor and camera tech. Bit long but worth a watch:

This was spectacular! Boulders instead of craters, who would have thought... 🤔
Kudos to all involved.

Yes, I can imagine how £400+ flat field Astrograph lens & reducer is better than £40 guide scope. However, if you do not want to spend that amount on guide scope there are ways how to make it better.

I'm currently working on a Vid for the HCG comparison between Gain 150 and 252
Oh look, some bloke made a video about the same exact thing. What are the odds? 😂
Joke aside, great video Chris. 👍

Patriot Astro has a three-part series on mini PCs that can be powered by a 12V battery.

better build, design and overall a sleeker look
I agree.

For guide scope suitability it is best to check at: http://astronomy.tools/calculators/guidescope_suitability. Historically, the rule of thumb for guide scope focal lengths was about ⅓ of the focal length of the primary imaging telescope. Your setup (72ED and ZWO 30) gives the imaging / guiding ratio of 1:3.5.
However, before you decide on ZWO guide scope take a look at the video below.
Also if you are not in a hurry, SVBONY can be found from time to time at discount prices in SVBONY store on amazon. I picket it up for € 40.
After watching that video above it was no brainer compared to ZWO for € 138 at the time.
Please note that it was some time ago and I got it at some deal (Prime day or something...)

PicInsight started posting introduction to PixInsight. This series consists of 36 videos and is dedicated to describing the graphical interface of PixInsight and its practical use at beginner to intermediate levels, from the most basic concepts such as workspaces, image windows and views, to more complex topics such as masks, processing histories, projects, and more.

it looks lovely to work with a stack of those
I have provided a clean (calibrated) stack of M31 at 254 at the bottom in the below post if you would like to give it a go...
Do let us know what you make of it...

AstroWorld TV Now, this is a special one. US based LIVE Stream Astro Photography focused open forum, with subjects ranging from hardware to post processing and from beginners to advanced. Quite often they will have shows with guests. Latest one was Nico Carver. They do giveaways, books, filters, AP courses, coupons... In June the gave maxed PrimaLuce EAGLE4. Drop in while they stream and ask anything AP related, it's good chance you will get an answer. Dan, Pete, Eric, Scott and Jessi make the core of the crew and they run twice a week with almost 200 shows already. As the show is live streamed they do get of the rails sometimes, but in a fun way. Give them few shows to warm up to your heart. Can't recommend enough! If you watch a recording make sure to skip first cca. 15 min as they play music while setting up. AstroWorld’s shows run long (2.5 hours) and are on YouTube, Facebook, and Twitch, every Wednesday and Friday night (Eastern Time Zone (UTC-05:00)).

Take a look at Global Meteor Network.
https://globalmeteornetwork.org/
You will find all you need there. It is free and if you choose, you can contribute your data to the scientific community.
To join the network, you can either buy a ready-to-use meteor camera or build your own from scratch – the parts cost around €200 (£170).
Software-wise, a pre-built OS image is available for Raspberry Pi – a 128GB microSD card is recommended. All instructions are provided.

I read that the wrong way, veeeery wrong vay... Sorry... 🤦♀️🤦♀️🤦♀️
Anyhoo, good to know, and good work. 👍

iOptron Cube Pro could be interesting price vise.
Great for light scopes under 3.6 kg, comes with hand controller, has GoTo, GPS, native AZ and EQ setups and unlike AzGTI, it can carry two scopes at the same time. Great for visual and usable to an extent for AP.
There is also a brand new (unprooven), belt-driven iOptron Sky Hunter, but not quite affordable.

not HubblePi guy,
After seeing your impressive galery, I'm sure you could help him too.
Btw, off topic, what are the odds...

ROTFL 😂
Made my evening... I didn't scratch under the surface, just remember seeing the article in MagPi.

There was a similar thread on this forum earlier, but I'll repeat in short. No, RpiHQCam will never come close to dedicated AP camera. Regardless good work on your part, I'm sure you learned a lot. Stacks were against you from the beginning, but before you give up all together you might want to check this blog and GitHub:
Hubble Pi — The MagPi magazine (raspberrypi.com)This guy appears to have made similar project, but not sure if he got further than you did.
Do check his documentation as well for details:
HubblePiDocumentation.pdf (hu-berlin.de)Good luck and be sure to let us know if you make further progress.

Smartphone coolers for AP
in Member Equipment Reviews
Posted · Edited by Dark Raven
Thought about it but the fan is DC 5.0 V...
After seeing this FLIR video I thought it might be enough with backlit sensor.
I had this below in mind as starting DIY idea, but than stumbled upon smartphone coolers and it took life of it's own.
Might still revert to it though... This TEC1-12706 Modul 36 W, 12 V might be ideal for ASIAIR+ port limit of 3A.
