Brightness Red Dot Finderscope, Star Pointer Viewfinder Astronomical Telescope Accessories with Slide-in Bracket

This is my first Red Dot Scope upgrade and it seems to work well! It does not come with directions but those are easy to find online. Basically look at an object through your main telescope in the day time about quarter mile out and center and on next in view. Then look in the scope finder and adjust it so the same item is in the middle of the Red Dot. After the adjustment things which were hard to see before came with ease! The scope does NOT come with a adapter base, you will have to purchase one separate and mount it for this scope to fix. After that things go together very well! I don’t have an old Red Dot to compare to but so far so good!

Se adapta perfecto al Celestron Astromaster 130

Good red dot finder. A red dot is a cheap alternative to a regular finder scope. I installed this on a Orion Starblast 6i. It fit perfectly in the dove tail mount that came with the scope. It came ready right out of the box, and the red dot is nice and bright.

The red dot pointer I received is a fair deal for the $$. The dot is bright. The dimming switch works well. The stalk holds the pointer a reasonable distance from the telescope tube.But there are negatives: (1) The stalk that supports the dot projector itself is plastic. One good hit and it will break. (2) Absolutely no instructions for installation or use come with it. Not even a small sheet of Chinglish. I have used these before, so I understand the basics. If you haven't, you may need to seek help (a more experienced friend, or something online). Instructions should have included how to install and sight, how to align, battery replacement, battery type. (3) The foot required some sanding to fit in the dovetail bracket on my telescope. I don't know if the foot was too big or the bracket was too small. One advantage of the soft plastic is that it was easy to sand down to a snug fit.Of course, I don't know if any of the other cheap Chinese red dot sights are any better.

It mounted easily on my Celestron Inspire 90AZ. The read dot is bright and useful. The mount can go on the scope both ways so you may need to unscrew and remount the scope depending on how your telescope connection is mounted. Great value for the cost
