This is my first Mak. It's so small and lightweight, it's extremely easy to balance and carry around. I got great views of Jupiter & Saturn. The moon is HUGE with this. The focuser is nice. Also: it comes with a fantastic carrying case that fits the diagonal, 2 eyepieces, laser pointer & barlow.

Superb quality, nice smooth adjustments, with tight fine movement, just absolutely perfect! It's more expensive than others in this size, but the quality makes it worth the price. The other popular brand of this size wedge breaks easily, as reported by several members of my group, even causing damage to their telescope. I am super confident this w

edge will never fail to hold and protect my scope.

ONE OBSERVATION THOUGH:
Some of the images on this site, as well as the manufacturer's, shows indexes labeled "latitude". This may NOT be correct. My wedge was not labeled as such and when I set my latitude, it was obviously not right, being a long way off. Then I remembered my other wedge uses "inclination", not latitude. Once I set the inclination, my polar alignment was perfectly spot on for elevation! That's a credit to the accuracy of the indexes.

To find the needed inclination (the physical angle of the telescope in relation to the ground), subtract you latitude from 90 degrees.
(Inclination = 90 - your latitude)

Btw, I think some older William Optics wedges may have indexed the wedge with latitude. I think this one is a newer version because there are some other slight differences with the images. But I absolutely love this wedge! Well worth the three fold cost over the other brand.

Very well done <br

Always helpful staff, product arrives when stated - great job!!!

Large stars and halo effect experienced with my previous OIII filter was my reason for buying OIII6-MAXFR-1. I saw a video from a photographer comparing OIII images taken with 2" filters, and I didn't hesitate much after that. I made a budget decision about buying 1.25" because my imaging cameras don't have full frame sensor. So far, I don't see a

ny vignetting when imaging with ZWO ASI1600MM PRO. What I see are pinpoint stars comparable with the stars taken with my 7nm HA filters. There is a small side effect which I like to inform about. It is not caused by the filter, but the filter is taking part in it. In general, my ASI1600MM is causing Newtonian rings. I see them only when making flats because of the light intensity. They are not seen in dark deep sky images. Now with this filter I see signs of them in the integrated deep sky images. Not easy to see, almost invisible but still present. Maybe because this filter was designed for work with very fast, up to F/2 telescopes it is somehow contributing to the effect. Those rings could well not be present when imaging with any other camera and could be specific to my camera only. If you don't see rings when making flats you most likely will not see them in the light images either. The rings didn't trouble me at all because the flats were able to entirely remove them. With this all said I strongly recommend the product for narrowband imaging. This is probably the best OIII filter that you could purchase for that money, and I am very happy with it.

Very solid piece of equipment and powerful green beam. The red and white lights are enough to read by. My granddaughters will love using it when they come and we set up the scope, lie on a blanket and look at the stars with the Binos. Much better than the high intensity flash light that ruins the night vision.
