Customer Reviews (4.8 / 5 · 5 reviews)

Timothy ★★★★★

I was worried about compatibility with my setup, but the threads on this receiver tube are machined perfectly to accept the NGC316 reducer without any wobble. My first test image showed noticeably sharper stars across the entire frame.

Eli ★★★★★

The 3-inch opening fits my OPTEC-3000 gear perfectly — zero play or wobble when I tightened the thumbscrews. Threading the NGC316 telecompress onto it was smooth and precise, no cross-threading issues.

Victoria ★★★★★

Finally got this mounted with the NGC316 reducer and the fit is absolutely rock-solid. The 3-inch opening gives plenty of clearance for my imaging train without any vignetting.
