Focal reducer/field flatteners
Hi there,
Is anyone using the William Optics P-Flat4 variable FF/reducer or similar?
I have W/O FLT 110 and an SBIG 8300c. Several DSO's are too big to fit into my 1.34* FOV - eg: Eta Carina, Rosette, Seagull etc. and I'm considering getting around the problem by investing in one if these.
What has been anyone's experience with these?
Cheers
Andy
