I haven’t had a chance to use it as it’s been overcast ever since it arrived. It you could guarantee clear skies along with the fast delivery and solid build quality it would definitely be a 6 star rating.
A great product to help center what you are viewing.
Center target in eyepiece, change eyepiece and your on target with new eyepiece. No hunting when you switch to higher power. Great real nice wide angle view.
Using this cross hair eyepiece makes GoTo mounts much more accurate, and set up easy. Once you have calibrate the finder to the eyepiece cross hairs, the low power and wide field mean that if you have centered the target in your finder, you will see it in your field. The dimmer has a wide range of brightnesses. For drift polar alignment this eyepiece is a little too long, and most people will get impatient if their scope is
I am finding the illuminated eyepiece very useful. ONE THING!: the metal the illuminator is made from is apparently VERY soft aluminum. If you aren't Very gentle with it (like tightening it with your pinky and thumbyou can easily overtighten it. I have NEVER had ANY piece of equipment that was so easy to mess up the threading on. Mine still works, but it no longer threads in completely, and I've had it for less than 48 hours. Just BE CAREFUL! Otherwise, seems to work very well. (Oh, and I see no evidence of the grid pattern one of the other reviews mentioned. Maybe they're thinking of a different eyepiece. This one just has cross-hairs, which is what I wanted.
Having purchased one of these I am very pleased with the ease of use and importantly the fact that the illuminated crosshair transforms into a fine grid pattern for final accurate centering. I gave this item 5 stars. Than guys. Brian.
