Reminds me of my early setup, Pentax K-3 with a cheap ass manual Sigma 400/5.6 on a shitty plastic cheapo tripod, it was as stable as a bowl of jello.
This is the only usable shot of the series from comet Catalina in 2015?-ish, even the shutter would shake the whole setup enough for visible kidney shaped stars so stacking didn't work. Also the cheapshit lens focusing ring had a very short throw so I had lots of fun getting things in focus in the -10°C cold
Current setup is not much better, tripod is stable now and I have working Astrotracer with O-GPS1, it is not much better than just a tripod with no tracking.
Early fuckups like this are inevitable but as soon as you see that green blob amongst the stars you just have to make your stuff better and it will move you forward.
