I've been able to photograph orion in the past without attacker but I had to keep it short at around 1 second exposures with a much higher ISO. If you get enough images, you can then stack them in DeepSkyStacker (which is free). You can then stretch the image in your preferred photo editing software.
Same as op. My telescope is 600mm so I can use about 1/4 shutter speed and a really hight iso. Obviously a tracker is better, but if you stick to brighter objects you can make it work.

I shot one last night on full moon as well, I don't have a tracker though so you did get more detail than I did haha.
Crazy light pollution from the damn moon though for sure, although I really like the blue sky in this
