Yes, that seems to be an accurate observation from my research as well.I have seen other forums that deal with these topics and there seems to be a general lack of ability to explain simply (while it is a complex subject - it can be explained).
I also get the impression that since all the equipment is so niche and expensive, any recommendations you'll get won't be based on elaborate testing and comparisons, but personal experience with a few pieces of equipment. And that's certainly still worth something, but such a different approach than what we're used to with cameras and lenses where every metric has been tested and debated intensely.
I like to take an approach to such topics that is not trying to go for the end goal in one step but rather tries to add minimal new stuff in each of many steps. I started doing milky way photography with my 600D and Sigma 35mm 1.4 Art. Then I got an 80D and later a Sigma 150-600mm and learned to use these properly for bird photography. Then I put the combo on a tripod and imaged the moon a few times, including a total lunar eclipse, and I tried to take an image of the Orion nebula using short, untracked exposures. Just to get a feel of what can be done with that equipment and where it falls short. Now I got the Fornax tracking mount, and a polar wedge, but no scope. I experimented with using a camera for alignment and have gotten better at that. I also got a light pollution filter, a new geared head and an intervalometer, but these still need to be tried out. Unfortunately the weather isn't cooperating. But with these small steps I can at least judge how much I really need. I try to only make purchases that I can use for regular photography as well. The exception to that are obviously the tracking mount and polar wedge. But compared to how much a lens / telescope would cost, that could gather more light than my current lenses, it is just the obvious choice.
To a degree, reading online has helped with all of that. But to make it really click, experiencing this stuff in your own or viewing videos and pictures seems more beneficial than all that technical talk to me.
If you pose a more specific question I'm sure you'll get a good answer on this forum. It's just that these recommendations I think require experience with at least some variety of gear and the cost of gaining that makes it hard to come by that experience, with the specialized forums being the place with the highest chance of finding it.
