I have considered an 8" f12 for the backyard. I think it might be do-able if the weight can be kept down.
My experience with the 5" f12 R30 Istar lens proved it to be very heavy for it's aperture. An 8" R35 would need to be permanently mounted for me as I think it would just be too heavy. I would prefer a standard achromat 8" f12 for that reason alone.
Mark if you ever offer an 8" f12 coated achromat lens in cell I would be interested. D&G offer them for the price of $2395 USD plus $275 USD for simple coatings on all four surfaces. That would be over $4000 AUD and who knows how long you would have to wait for it, maybe years.
I don't know if it would be commercially viable for you to make a run of them in Australia. What do you think?
