Ocular Instruments Opinions

[jamface10]

Hi, I just wanted some opinions on ocular instruments. I'm looking at the maxfield glass options.

• Anyone used the Gaasterland 4 mirror gonio with removable flange?
• Does ocular instruments have a Superfield equivalent lens? Looking at their product catalogue the Standard 90D has a FOV of 94 which seems pretty similar?
• How good is the Laserlight HD AR coating?

Thank you very much.
