I wondered if someone could post an image that shows how mars would look in size compared to Jupiter and the other planets. I am sure that I had mars in my scope using 25mm and a 9mm and it was quite small and I couldn't see any detail what was I doing wrong if anything? If I had a reference picture showing relative sizes through a scope I could keep trying if I wasn't getting the same results. I have found Telescope Calculator so that should solve my comparison problems but if anyone can tell me if iam doing anything wrong as I only just saw mars a disc. I am happy to have this thread removed if desired if there is no advise as to what I am doing wrong.
