不如老闆你試吓，再出個報告來睇睇…或買來借我哋試吓（講笑）

Zero powr flattener is not that useful to me. I am looking for focal reducer -- which will at the same time make the telescope FASTER.

Any focal reducer for f/6 to f/8 telescope?

這個減焦鏡（￥80），可以嗎？注意會令焦點向物鏡端移前3-4 cm，有機會不能對焦：

我己有類似的東西(智通產品), 但和這個一樣, 都是1.25吋, 那用於DSLR個有暗角問題, 我想找2吋0.7x 至 0.8x 產品。
