So im tempted to get a spotting scope. One that I could use for casual astrophotography without the bulk, and for wildlife. But I dont even know where to start. I obviously want something lightweight that I can take on a walk in my rucksack, but that I can get some nice magnification ( say x30- x60). I also would prefer to get something thats easy to find second hand. I see a lot of guides online but weight never seems to be a consideration. Does anyone here have experience/ can help me with where to start my research?
