    It was on ground sites. It’s all good to see. The picture is clear and bright.
    With a 32mm eyepiece, it is better not to use, with 21mm and less-excellent.

  12. Oscar Álvarez

    As always good quality, this is the second reference that I bought in sv bony. Fast shipping, lens always mounted to the back, you will have to unscrew the inner ring to return the lens and be able to use it. Apart from that very good product.

  14. Wendi Raver

    Nice little focal reducer with bright light transmission. There is some deformation along the borders, particularily with long focal eyepieces, but I think is much more noticeable in fast telescopes with large aperture. My old f15 refractor goes pretty good with this lens. I have to try it with camera on the moon.

  15. Jaqueline Phipps

    The goods came safely and safely, delivered the courier to the house, packed all tightly and well, the seller recommend, there are small shortcomings from the outside of the case, observations are not as not affected, there is enlightening, achromat all as in the description, there are small distortion of the image along the edges with the eyepiece svbonnie 20mm, 66 deg is not critical, the product is satisfied, I definitely recommend.

    This focal reducer, for the price you have you can’t expect wonders, I actually bought it for visual and astrophotography, in visual it presents quite an aberration on the sides, for astrophotography I wasn’t able to focus with the SLR camera because the focus system is short, Like the camera should be inside the telescope, I don’t rule out that I can still fix it somehow and maybe for a CCD camera if it works even though I suspect latrural aberrations will not be corrected. My telescope is a Newton Sky-Watcher D254/F1.200mm.

    The lens came a little loose and I had to squeeze it by turning the inner ring. I hope it’s not out of line.

  47. Reiko Jeanlouis

    The problem with this lens is that introduces a lot of aberrations. I’ve tried it with a small sensor CMOS camera (QHY5III462C) and the results are awful. Perhaps the visual experience will be better
