In Sweden we have a famouse mirror grinder, Joel von Knorring. Have you heard about him? I couldn't find any article in English for you.

I have used it a couple of times for imaging but it's a big beast up on the EQ6 and fills up most of the observatory. I may give it another go now I have just bought the ZWO ASI 1600mm-c but the off centre weight might be a problem. To be honest I don't do much visual through any scope now, mainly imaging.
I haven't heard of Joel Von Knorring. I have built an 8F8 astrograph similar to the 10' using a Gary Nankivell mirror. He designed and built the 1 meter scope used at the Mt John Observatory in the South Islands Gold Class Dark Sky area at Tekapo I picked it up from his estate to build a long focal length astrograph which would have minimal coma. I need to make that work again but being 1600mm long it fills up the Observatory as well. But it does take good images.
