Unfortunately large refractors are a thing of the past in professional astronomy. I personally love the look of these classic instruments although they are not very practical to use. Below the image of the 65cm Zeiss refracotr of the National observatory of Japan. It is unused and serves only as backdrop of the museum housed in the dome.
There are some special application scopes as the mentioned solar telescope but they are rare these days.
Super thing that large refractors are NOT things of the past in amateur astronomy. I also love their look and to me they are very practical in their use.
