This is the large reducer flattener that is matched to our 152 mm f-8 and 180 mm f-7 refractors. This version has adapters and extensions optimizing it for use with a DSLR equipped with a t-ring or a CCD/CMOS astronomy cameras with a 55 mm back focus such as ZWO cameras. It flattens the imaging field and provides about .75X reduction.
This is an imported reducer/flattener. It performs on par with other reducer/flatteners for sale. Based on the success of our in-house field flatteners (which work with full frame sensors), we are currently developing an in-house reducer flattener. We plan to have this new unit available by the end of 2024.
To order, first select the camera thread size and then what focuser your telescope uses.
If your camera setup has a different back focus you can add or subtract M69 extensions. If you are unsure about any of this please contact us at firstname.lastname@example.org or call (530) 823-7796, Monday - Friday 9-5 Pacific time.
