Now you have made me feel guilty ... I need. to pull out the APOMAX
Rare indeed, Roland only made two of these astrographs, with 4" focuser and 4" FF and a 90mm corrected image circle. He then changed the glass supplier and produced its successor, the 155EDF. So it is indeed a real collectors item

Needless to say, visual views through it are exquisite. I recall clearly seeing the Red Spot Jnr back in 2005 (?) and detail within the Great red spot, easily split a 1" double and 6 stars visible in the Trapezium at 50X magnification.
