Thanks for your input Andy , you sure have had some nice scopes !
Mel & I like you would love to score a classic 8" refractor one day .

I would have trouble lifting such a big scope but Mel would have no problem & could probably handle even a 9" F/15

I used to browse Sky and Telescope magazines at the local libraries. Then I ordered a D&G 6" f15 lens from the USA and was amazed by the high contrast and flat field. The telescope was big and bulky but I made it work by having a permanent pier always ready to go with a simple alt az mount. The telescope was less then 15kg and easy to bring out of the shed and set up quickly. I never had to deal with collimation or tube currents or mirror recoating. Later I also had an Istar 5" f12, Antares 90mm f16.7, and a D&G 5" f15. All with lightweight thin ply tubes. Still think I would like to try a 6" or 8" f12 one day.

That is amazing collection of refractors you have Andy. I think a 8" long focal length refractor would be awesome in you already amazing setup of refractors.

Long f ratio refractors appeal to me too. Some restoration to this 152mm f15 with lens by Barry Adcock resulted in a beauty. The enamel paint took many weeks to harden before the telescope could be mounted in the rings without marring the finish. Cheers Mark

That is a nice looking scope Mark and nice work on the restoration.

I ended up with Barry's 6" triplet which I enjoy using when I went to look at both scopes.

for a little steampunk and long F/l refractors is hard not to be impressed by what's on the Moonraker site imo.

To answer the original question. If we are honest with ourselves. The answer is no. Astrophotography has gripped the users and manufacturers alike. More and more R&D and products on the market are for shorter focal lengths with more compact and mobile mounts to make setups more - what's the buzz word in the business communities, "agile"?

I don't think large, long focal length refractors have much of a future in the heavy light pollution world we live in. You can at least fit large SCT's and Dobs in the back of a small car to seek those more pristine sky's. The hassle of storing and moving a large long refractor and mount is objectively not worth the effort.
