## Customer Reviews

### ⭐⭐⭐⭐⭐ Great finder scope
*by  on Reviewed in the United States April 28, 2025*

This finder scope was exactly what I was looking for, it was a significant upgrade over the scope I had previously. I had to replace the custom mechanism for the telescope to a dovetail connector base to make it fit, but most accessories use that standard dovetail, so I would have needed to do so anyway. Once I've replaced the base with the dovetail one, this fit perfectly.The image through this finder is clear, it is easy to align (although, you'll have to align it as perfectly as you can on as far of an object as you can). I've used it a few times for finding planets and stars and have had no issue with viewing the night sky in terms of brightness, and finding what I wanted to focus on.I've seen a few reviews indicating it would be nice to have crosshairs to make it easier to see the centre, but on the scopes I've seen those crosshairs, they're on the side of the eyepiece, so it should be possible to add your own, it's also better to be able to choose crosshairs that are visible at night, because quite a few have crosshairs that are effectively invisible at night on the dark sky.Just to note, this is not an all-in-one, the eyepiece adapter is a standard one that fits 1.25" eyepieces, so make sure you have an eyepiece of your own. This has the upside of making the magnification of the scope modifiable as desired.

### ⭐⭐⭐⭐⭐ Crystal clear sharp pinpoint stars
*by  on Reviewed in the United States April 28, 2021*

Have not used it yet as a guide scope but did add a 25mm eyepiece and tested it out during the day and at night on the moon and a couple of stars just looking through it . Sharp crystal clear images!!!Pin point star images , sharp clear craters on the moon. Daylight viewing just as sharp. Helical focuser very smooth. Holder bracket has a nice tight grip on the body. My only dislike was one of the screws to hold the tube in place was missing the Teflon cushion pad but I can deal with that minor issue. I have no doubt this will be an excellent guide scope. This was my first ever guide scope and I'm glad I bought it to compliment my Astromania diagonal astrophotagraphy flip mirror .

### ⭐⭐⭐⭐ Great Finder with Two If's
*by  on Reviewed in the United States July 9, 2019*

The 50mm Astromania finder features great optics and the potential ability to use the finder as a telephoto lens and use the finder in a straight through mode, 45 degree prism mode, or 90 degree prism mode. You can loosen a set screw to adjust the draw tube that holds the eyepiece or prism diagonal. You get a wide range of focus options, but it will not work for all prism/eyepiece combinations. Also, because of the sliding draw tube, you don't have an internal baffle. When sighting on an object near the moon, you will get a lot of annoying stray light. It's a well made accessory with the caveats mentioned.
