USING THE SFFR.72 LARGE REDUCER/FLATTENER

WITH THE STELLARVUE SVX130T-35SV (3.5” FOCUSER)

The optional SFFR .72X - 130T

reducer/flattener converts your

SVX130T into a full frame astro-

graph for wide field deep sky pho-

tography. It reduces the focal length

to 650 mm and the photographic

speed from f-7 to f-5. To install and

use it follow these simple steps:

1. Unthread the rear assembly
including the 1 1/4” adapter, the 2”
adapter and the rotator.

2. Make sure to leave the M75
adapter in the focuser.

This giant reducer/flattener will convert the SVX130's f-7 visual optical system to a 130 mm f-5 (650 mm focal

length), full frame imaging system. The SFFR.72-130 reducer flattener has a 69 mm back focus using an

M82X1 rear thread. Purchasing various versions of this reducer/flattener with the appropriate extension tubes

and spacer rings will enable it to be used effectively with various cameras on the market. If the camera’s ccd

chip is not spaced correctly from the reducer/flattener stars in the corners will appear elongated. If you are not

sure how to properly set up your reducer/flattener and camera, call us at (530) 823-7796 or email us at

[email protected]. We want you to get the most out of your system so if you are ever having difficulties we

want you to call and let us help.
This full frame reducer flattener has been responsible for many of the amazing images taken with our 130 mm

refractors.

3. Thread by hand the reducer/flattener into
the focuser’s M75 adapter.

4. Thread by hand the camera onto the reducer/flattener.
Make sure the ccd chip in the camera is spaced correctly from
the reducer/flattener (see page 15).
