No, I haven't seen anything commercial although I've heard rumours. I will make something to fit my 300mm KM tele when I've sorted the ob out. Biggest issue is the short distance to the focal point so the EP would just be in line with the OTA, no diagonal. A barlow might work here maybe.
My other option would be to pick up one of the little 80-90 f8 mirrror camera lenses. Some of those come as tele and scope options with their own diag etc. I've seen a few go through on trademe recently. Biggish centre obstruction but very compact with longish FL and no CA.
I'm also keeping my eyes open for an old 400mm manual lens from the old days. 85mm objective, f 4.5 or so. Would be a good conversion as a guide scope even.
