You'll notice these do not have guidescopes. That is because we use something called an OAG, or Off-Axis guider. This involves using a prism to grab a small amount of light that is otherwise wasted due to the size of your main cameras sensor. They work the same way as a guidescope, but are a little more difficult to use if you are just getting started. That said, they are a great way to cut down on weight and can offer even more accurate guiding, but also do not provide as much light to the guide camera compared to a dedicated guidescope. As such, it is wise to use a more sensitive guide cam. Its up to you to determine what you think will be best for you and your wallet.
