Space Monkey

Hi everyone I have been having a long think recently about what I want to do next in this hobby as I have been enjoying visual astronomy for a long time and have loved every second of it but I think it is time for me to move on to astrophotography as this is something I’ve always wanted to try. I now have the funds saved for a decent set up that will get me started. Around £1000-1500. I am looking for something that it relatively portable as I would like to take it on hiking trips to dark sky sites. For the ota I kind of had my eye set on the William optics 73 ( no pun intended), which I might also even use for visual as a low powered scope. I am just pretty confused on what I need to buy and which mount would be the best for a portable setup but still capable of long subs. I also have a dslr which I can use ( not modified) and have been looking at some asi cameras too. I have been reading a lot of threads on here but I’m still pretty confused on what to get so any help would be really appreciated. hope everyone had a good Easter!
