I recently have gotten into longer focal length refractors courtesy of my Broken Hill friend's influence.
I have a new refractor alt az mount coming soon for two of my long focal length refractors - one is a 6" f/8.3 triplet and the other one is a 6" f/12 Istar(pictured).
I find them somewhat drawn to them and a joy a use when use for the particular objects I like to use them on. I am plan to keep all my long focal length refractors and add to the collection where possible.
I am aware that most people are going to shorter focal lengths for refractors and as the years go back will see less people wanting to own and use one. I hope there will be more people that become aware of them and still happy to do some visual viewing with these scopes.
