ASTROPHOTOGRAPHY

While telescopes are designed to be used visually, they may be easily converted into a super photographic

lens using one of our dedicated photographic correctors. You remove the eyepiece, star diagonal and 2”

adapter from the focuser and you replace it with either our field flattener or focal reducer/field flattener. 

Important! When using a field flattener or flattener/reducer, it is essential that the camera’s sensor 

is positioned at a precise distance from the back of the field flattener or flattener reducer. If you see

elongated stars in the corners you will need to adjust this spacing. Call or e-mail us if you need 

assistance! 

There are two types of correctors made for the 

SVX102T

and 

SVX102T-R

, one is a 

flattener and one is a reducer/flattener. 

SFF4-102T Field Flattener

: This full frame field flattener is made specifically for the 

aluminum tube SVX102T and the carbon fiber tube SXV102T-R using the Stellarvue

FSV3 3" focuser.  

SFFR .74 Reducer/Flattener

: This is the Flattener/Reducer designed for the

SVX102T and SVX102T-R using the 3" Stellarvue focuser. This reducer/flattener

converts the 102 mm f-7 714 mm focal length objective into a 102 mm 535 mm

focal length f-5.25 wide field imaging scope. Merely un-thread the 2" adapter from

the draw tube on the focuser and thread this unit into the focuser draw tube (see

page 16). Please note: Since this unit threads into the focuser it cannot be used

with any other focuser. 

Without a corrector, stars will become 

elongated away from the center

With a properly spaced corrector stars will

appear as they should
