Hi everyone! Just received my first proper telescope, the skywatcher 72ed. Have a few questions about it which I haven't been able to find the answers to anywhere. My scope seems to not have a retractable dew shield and came with a lens cover that just pops on and off rather than a threaded one like I have seen many others. Is this just the updated or newer version of the scope? I also am wanting to get the stellamira 0.8x reducer and flattener and know its compatible with the scope but unsure of the adaptors needed for it. I have got the m48 t ring to attach my dslr and also have the skywatcher camera rotator. I have seen that apparently the rotator isn't compatible with that flattener, only the skywatcher one and ifs that's the case then that's fine but what adapters would I need to be able to connect it all up? Thanks in advance and clear skies!
