Astrophotography requires more experience with the telescope handling, a more stable platform and usually the best beginners telescope for observing isn't ideal for photography.
For photography you should plan at least $500 for a tracking mount, you might start even with the cameras lenses or a small refractor telescope. "Barndoor" mounts are a good alternative for not too long focal lengths.
Photographic mounts for the recommended 8 inch newtonian would run at $ 1500+ and require precise setup.
The good news is, that modern digital cameras with interchangeable lenses are pretty capable for astrophotography, so if you own one of those, there is no reason not to try it. So the strong warning in the article was to set the proper expectations.
Couldn't you use manual tracking at first? The steadiness of the tracking isn't so important if every individual exposure is short, and most cameras have a continuous mode so you can take many thousands of photographs. I've successfully stacked hand-held photos using Hugin:
You will probably need a camera with raw support for this to work, because each individual exposure will be extremely noisy, and any in-camera noise reduction will destroy too much detail. You will probably also need at least two bright stars in frame for alignment to work.
And if you have a huge number of images you can also keep only those with low atmospheric distortion:
That could work - and I am a strong believer to try everything, even if the equipment at hand is not "officially capable" of doing the task. If one does that in the proper spirit of experimentation, this is great and you learn a lot and can have tons of fun. People who have no astronomy experience might though think that you can just take photos as you see them in the web or in magazines.
