Re: 140/155 4” Field Flatteners

The Sony IMX411 is 67mm on the diagonal, 151mp (14304x10748, 3.76um). It's the medium format version of the IMX455. I would absolutely love to be able to image with such a sensor and the fov on a 155 would be jaw-dropping. It would definitely require a focuser upgrade to carry that monster, though. One can dream!

The PF562 field flatteners cover 65mm easily. Do you think there will ever be larger chips?

Roland,

What about larger chips in the future?
I made the mistake of not ordering it when I received my 140 back in 2008 and have been looking out for one on Astromart for quite some time.

Roland,

Any interest /possibility in a run of the 4” FF for the 155/140??

Yes, that is the one we are looking to make. If enough interest (seems to be) we will make a small final run.

Are you talking about the 67PF562 Field Flattener?

I have a Starfire 130mm f/6 Starfire EDF APO.  I believe the 67PF562 is the flattener for this scope and have been looking to purchase one for a while.
