What Barlow to use with a 5" scope (to capture outer planets)?
I currently have a 2x Barlow and tried it out on Saturn the other morning. I was able to capture Saturn but it was quite small and had no detail on it. I had to increase the exposure and gain a bit.
I know a 3x Barlow would increase the size of the planets but would I be able to capture enough light with my scope using a higher magnification? Would I even be able to get away with a 5x Barlow?
Thanks.
