I have a brand new Hotech - Self Centering -Field Flattener for f5-f8 refractors for sale. I bought this Field Flattener for testing on my f5 Achromat scope that I was developing for narrowband imaging. It has only been on the scope twice for spacing and focus testing. It turned out to be unsuitable for that scope (which has a rear mounted Petzval corrector). I have decided to sell that Acrhomat scope and the Flattener is no longer needed.
So I am offering it here for any APO, or other fast refractor owners, that would like this nice Field Flattener.

Current pricing from most retailers is $160 USD plus international shipping (circa $208 Aud).

I am asking $160 for mine, and this includes shipping to any Australian address via Registered Parcel Post.
PM me here if interested.

If I may add, I am using this exact flattener with my ED80 and it works wonderfully to fix the distorted stars in the corners. It is also easy to connect to a DSLR as just using a t-adapter gives the exact distance to the sensor.
