NGC316 修正器/減焦鏡 0.75X 鏡頭 – 第二代 (17480)

Finally got this mounted on my 16-inch SCT and the star shapes across the entire frame are noticeably tighter than with my old reducer. The three-inch barrel threads on smoothly with no play, which was my main worry.

The 3-inch barrel size makes a huge difference at the eyepiece—backfocus is finally manageable on my 16” scope. Stars stay tight and round across the whole frame, even at the edges. It’s pricey, but for planetary imaging this was a real upgrade.

After struggling with coma on my 16" SCT, this corrector flattened the stars across the entire frame on my first night out. The 3" telecompressor design is noticeably more solid than the smaller units I've used before.
