مخفض بؤري-مسطح-دوار لتلسكوب SVX152T (SFFRR.72-152-48)

The back focus adjustment on this reducer-flattener is dead simple to dial in, and it cleaned up the stars right to the edges of my full-frame sensor. My first light with it on the 152 showed no tilt or distortion even after rotating the camera for framing.

I was impressed by how precisely the rotator clicks into place—no guesswork when framing a shot. The reducer-flattener definitely tightens up my stars across the entire frame compared to without it.

Installed this on my SVX152T last night and the back focus was spot-on right out of the box, no shimming needed. Stars across the full frame of my ASI2600 are tight and round.
