Good summary Ben. I’ve been too distracted by other things but would like to have the G3 as an option. Happy to try and pick this up again although some bits might take a while.

xthestreams I've attached my current version of the serial pass through script (very much just a tinkered with version of the one attributed at the top).
It still has a way to go to a level of maturity that I'm happy with.
I occasionally get junk characters show up in the serial monitor and I will explore at some time moving the Wifi router login elsewhere.
Either into a separate library reading it in from a text file or perhaps using the technique of using a wifi hotspot initially to select the router and enter a password.

Some ESP32 boards arrived today with along a pair of the 8 channel relay boards so I'll probably redo the roof control unit to both properly isolate the control from the relay control and possibly to use an ESP32 as the controller (wondering how the 3.3V will go with the relay modules though).

Thanks. I like the idea of a hardware section.
A little bit of possible learnings about my Ebay version of the Wemos D1 Mini board and my attempts to use it as a serial bridge.
I found elsewhere mention of 470ohm resistors in the TX and RX lines on the Wemos D1 mini boards hindering comm's through those pins. My boards hava 220ohm resistors. I've been experimenting trying to communicate through the pins, via a level shifter then via a Sparkfun FTDI board on one side and a Telnet session to the board over Wifi. I get one way comm's with that setup.
Stuff I type into the Telnet session shows in the serial monitor but not the other way. If I'm using the USB port on the ESP8266 I get two way comm's.
I'm suspecting that the issue is that the signal coming from the FTDI board via the level shifter and into the ESP8266 board via the resistor may not be sufficient (either that of a problem with the hookup of the level shifter). I'm also noticing that the ESP only shows as connected to my router some of the time even when the telnet is working. That was a lot confusing.

I have the Jaycar version o fthe board somewhere (but not sure where at the moment). When I find it I'll check the resistor values in the TX and RX lines and see if they are any different.

xthestreams, based on the description under your alias you might have a better idea than me. Is this an appropriate forum for discussions around hardware such as the ESP range? It does seem relevant but also a bit of a tangent.

I seem to be collecting a multitude of ESP8266 based boards (and some ESP32 boards on order) on the basis that some people seem to be able to make them work. It is a dark art though.
I can get the boards to connect to my home wifi when they are attached to the USB device but not when I power via other means and in the case of the Arduino Mega with the onboard ESP8266 module similar but that's based on DIP switches.
Still experimenting in that space as a Wifi module that needs to be powered via the USB seems unlikely.

I'm pondering modifying a sketch that connects and add an interface to a serial LCD screen to see if that gives me a better idea what's happening when the USB is not connected.

I've not yet located a basic sketch to use the modules as a serial pass through that gives me any confidence that it will work. The esp-bridge may do what's needed but I'm still trying to get my head around what they are doing, use of AVRDUDE is different to what I was expecting.

xthestreams, do you have a suggestion on a particular WeatherRadio build? The most promising site that I found appears to have had it's links hijacked by an asian porn site.

No visible central blobs using the other telescopes.

I do have moderately high light pollution (I'm just outside Brisbane) but not extreme. It all seems pretty strange that I didn't get any of the with the Canon 550D (other than the prior mention of the possibility of it being IR).
I don't currently have any filters in the setup although am pondering adding some filtering to dry and reduce the sky glow. An area I need to do some more reading on.

I didn't get it with a Canon 550D on the ED100 (stock camera). I've not worked out the relative sensor sizes.

Minhlead, thanks for explaining that.

Other than finding that I'm not getting the issue with my reflectors I have not.
The original issue was occurring while using a Skywatcher ED100. I've since tested with a GSO 153mm F4 newt (with Coma corrector) and other than bad coma (I need to revisit the whole spacing question to resolve that) and a Skywatcher F12 150mm Makautov Cassegrain which is looking really promising.
I'm concentrating on trying to get that all working at the moment so I can take advantage of some nice weather and deal with the tests later.

I am still quite confused as to why I don't see the amp glow up near the top right corner in actual images as well. It's really obvious in darks but no sign of it in any of the lights I've taken. That has me wondering what deep sky stacker does to that part of the image when it's working with darks which have a glow in that spot.

It seems like I'm either getting some reflection from light leakage in the ED100 or the tube is too narrow for the sensor (although I've not seen any documentation to support that suspicion).
I did also get an odd search light type pattern on M4 which at the time I'd put down to the tube picking up light from somewhere else but thinking about it that showed up in every M4 image I took which seems unlikely if that was an artifact of some stray light..

Thanks for all of the feedback. Is does appear that the issue is with my physical setup rather than the camera itself or software configuration so I'm thinking the topic has run it's course here.
I will try and work through the suggested tests.

In the interim I''m going to give the F12 a try and see how that all goes. Gave me a good excuse to build up another focuser control. I'm trying an ESP8266 version of a myFocuserPro2 (which I did before finding the existing doco so I may have some adjustments to make).

I think that one was a 300 second, 150 gain image. It was a straight export from Gimp. The amp glow thing had me wondering as well. The amp glow pattern show in on the companies website is really clear in darks but I've not spotted it in any images taken of the sky using as far as I can tell the same set of settings. I'm doing some testing tonight with an F4 Newt and now seeing the spot. I have done a clean of the lens and had the diagonal out of the path in the refractor so it seems unlikely either is the issue.
Is there a chance that a 100mm 900mm refractor is too narrow for this sensor? Interference from the tube is about all I can think of at this stage (although it looks fine to my less than knowledgeable eyes)

The F4 didn't guide particularly well on my mount in the past so I'm not keen to swap back to using it (and need to work out where the camera would need to sit in relation to the coma corrector).
I've also got an F12 Maksutov Cassegrain and I'm wondering how it would go with this ASI294MC. That might be my next experiment. Weight wise combined with the focal length may make it a bigger challenge to do the kind of work I want to do (and I'm somewhat interested in the wider views).

Derpit, when you say aperture closed do you mean the front cover on the tube? There is a light leak around the focuser tube. I should be able to try that pretty easily even with the tube off the mount.
By the same token I'm thinking I can get around the not yet developed driver for the dark/flat flap and just bypass some wiring to get the flat light source running.

There is a free version of Sharpcap, I'll have a look and see what it can do. Feature comparison between the free and the paid versions is at www.sharpcap.co.uk/feature-comparison
