It has worked out well for me. But you are right to be suspicious, remote imaging can be a house of cards. It is not for everybody. I started playing with automation in 2003 or 2004 and my equipment has evolved a lot since then. I ran my backyard observatory automated for about 9 years before I seriously considered trying remote imaging. I could have done it much earlier, if I had been more serious about it, but I am glad I took my time. Once I was able to run my backyard observatory without touching the rig or building for six months of running every clear night, it dawned on me that I could do it remotely with a reasonable expectation of success.
Reliability is the thing, and designing things so you can recover from failures of all types. It is absolutely necessary to have local help of some kind and security is always a concern. I have all of that covered to my satisfaction and it is approaching a year since I have visited. I have been very lucky this year but I have had help from others. But last year I made four trips...none due to critical failures. I have been lucky. But I am able to make the trip if needed.
