I would like to share my third image.
I finally had a "lucky week", since my last session, December 18th. I managed 5 clear nights out of the past 6 (has to be a record, at least for me and my area) and I was able to finish a couple of projects I had started long ago and start a few new ones.
This is M33, also known as the Triangulum Galaxy, taken over 10 nights, under my Bortle 5/6 home sky.
Total integration time: 10h 14m 00s.
Here are the acquisition details:
Mount: Sky-Watcher NEQ6 Pro
Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series
Camera: D5300 astromodified
Reducer/flattener: Tecnosky 4 elements, 0.8x
Guide-scope: Artesky UltraGuide 60mm f/4
Guide-camera: ZWO ASI 224MC
2020/11/08: Number of subs/Exposure time: 11@240s. Notes: L-Pro filter, no Moon
2020/11/09: Number of subs/Exposure time: 10@240s. Notes: L-Pro filter, no Moon
2020/11/20: Number of subs/Exposure time: 15@240s + 4@300s. Notes: L-Pro filter, Moon 30% illuminated
2020/11/21: Number of subs/Exposure time: 22@300s. Notes: L-Pro filter, Moon 45% illuminated
2020/11/24: Number of subs/Exposure time: 20@300s. Notes: L-Pro filter, Moon 75% illuminated
2020/12/13: Number of subs/Exposure time: 12@300s. Notes: L-Pro filter, no Moon
2020/12/14: Number of subs/Exposure time: 8@300s. Notes: L-Pro filter, no Moon
2020/12/18: Number of subs/Exposure time: 6@300s. Notes: L-Pro filter, Moon 20% illuminated
2021/01/10: Number of subs/Exposure time: 9@300s. Notes: L-Pro filter, no Moon
2021/01/11: Number of subs/Exposure time: 15@300s. Notes: L-Pro filter, no Moon
Total exposure time: 36840s = 10h 14m 00s.
Pre and post-processing: PixInsight 1.8.8-7.
Image was Drizzle Integrated and then cropped to original sensor size (6016x4016), without resampling. So, it appears as if taken ad double the focal length (768mm instead of 384mm). Image scale 1.04 arc-sec/pixel.

Thanks for looking!
Made a new video, this is a Astro Systeme Austria specific video, which has direct driven servo motors.
To get them to perform perfectly and be able to track unguided, you have to tune theese motors.
I made a quick video of how the three different methods is working in the "Autoslew" software to run theese mounts.
Maybe this method of tuning mount motors is related to other brands which has direct driven mounts?

The 6th January was clear and still and so at last a good night for imaging (not perfect as Moon was still waning).
My 8" SW 200P Reflector was wanting to be used and so it was carefully mounted onto the HEQ5 and payload maxed out with the imaging train.
Yeah I know - this combination is a big ask for the job (but an EQ6 is beyond me at the moment!). Anyway with careful balancing and hardly any wind it was worth trying!
Nebula were best targets and again new ones for me.
These were the Bubble Nebula, Cave Nebula and Monkey Head Nebula. The Optolong L-eNhance Dual Narrowband Filter was used for all images.
Usual calibration frames and dithered instead of Dark's. Other 'Astro Stuff' is in my signature.
Any constructive criticism's welcome.
Bubble Nebula (Sharpless 162) 15x240secs (1 hour of data).
Cave Nebula (Sh2-155) 7x240secs & 23x300secs (2hrs 23 mins).
Monkey Head Nebula (NGC 2174) 44x240secs (just under 3hrs).
Hi all, just getting straight to the point.
Just got a Rasp Pi 400 (equivalent to Pi4-4GB), and looking to get into guiding through this as it's obviously a popular (and successful) technique.
Plan is to have the RPi as mini computer at home, running it with RaspPiOS (supplied on µSD with the full kit), then use it with a SECOND micro SD card for astro - I figure having another SD to run Astroberry (as on SGL) may ignore any issues with the family using the pi for other stuff in the house, giving a stand-alone 'computer' as the OS and files would be available on different SD's.
From this point, I'd setup as follows:
Connect the RPi directly via USB to the mount (it's the newer SW-AZ-EQ6Pro with the USB-B port on the mount)
Guidescope (240mm f/4) with T7C (equivalent to ZWO Mini) again USB-B direct to RPi
Nikon DSLR (either on telescope or using camera lenses) connected to RPi via Nikon USB (using the 3 USB points on the RPi-400) to control capture and later using this for plate-solving (but that's not for just right now!)
I don't spy any flaws in the plan, it's just going to be a matter of testing and setting things up hoping to follow the guide for Astroberry as linked to SGL below...
Or is there an alternative OS? From brief reading, Astroberry includes KStars & PHD2 which is what I've got for use on the macbook (although not used in earnest as it doesn't appear to like the cold too much!)
What about guiding software - I know KStars comes with it's own, and can run PHD2 from within, with PHD2 being the industry standard (and simplest?) to use?
Control will then be sitting in the warm via OS-X, which seems to be again a common technique as I've had posts on my other questions about this!
