SVBONY SV182 Finder Scope, Right-Angle Correct-Image Optical Finder, 6x30mm | Telescope Finder Scopes, 90°Right Angle Diagonal, Neck Relaxed, with Crosshair and Bracket, Robust for Astronomy Telescope

Great quality finder scope! Well built, sharp optics, easy to align, and sturdy. The best part is the right-angle viewing, SO much more comfortable than straight-through finders. The correct-image really helps too with proper orientation to what I see in the night sky with my eyes. It's also internally baffled which helps control stray light and the field of view is a large 7.5°. Big upgrade from my previous finder scope. Excellent product and I give it a big thumbs up!

This is the best little finderscope I've ever owned. I use it on my SV 48P telescope all the time. It has just enough light grasp to be quite helpful in my suburban skies. And even more valuable than this is the right angle diagonal and correct image view. After years of using finderscopes with their upside down & backwards images, I'm worn out, both by craning my neck around to the finder and constantly doing the mental calculations to make sure I'm going the right direction while I'm star hopping to my targets. What obnoxiousnous. Now I just look down in the finderscope eyepiece and see a view that aligns with my eyeball, just magnified more. In fact, I must state that in a way this finderscope has rescued me from giving up on visual star observing, especially from city skies. It's got enough ability to facilitate star hopping and thus observing from my yard, instead of being dependent on dark skies a 90 minute drive away. Thank you SvBony. I can definitely recommend this product and will be buying more as needed. Addendum: I now own four of these. Energy single one of them works out of the box, sharp and clear. Can't recommend them enough!

I own two of these. The price, when on sale is quite reasonable for the quality. The scope is multi-coated and quite bright and has easy to see cross-hairs. Crosshairs can be rotated to match your preference. Focusing is done by rotating the objective and then locking in place with the red lock-ring (if using for astro, this only needs to be done once...) The issue with this finder is its mount and alignment system. (Mount itself is sturdy cast aluminum). The finderscope is held in the front of the mount via friction of a rubber ring. This ring seats reasonably well but is not rock solid. In the rear there are two adjustment screws and one "adjustment spring" The spring is "self-adjusting" (yes - not user adjustable). The spring just does not provide sufficient grip/push to hold the finder in alignment. The screws need constant readjustment to maintain alignment. This is such an obvious design flaw, yet I see this design being in used in many inexpensive finders. It does not hold alignment! C'mon SVBONY - the fix is so easy. Just do what I did - screw out the spring thingy and replace it with an actual screw. I had to find a bolt to fit the hole size and I tapped out new threading for that bolt. With three screws it holds alignment pretty well (although the rubber band at the front I am still dubious of. The second SVBONY guide scop0e I have is mounted in the traditional two rings and six adjusting screws manner - it works great that way, Overall - Nice finder and optics, but dubious mount.

Excellent quality from SVbony, as always.

I like this finder scope a lot. My neck LOVES it! I tried a standard spotting scope once and my neck tapped out before I could even get a view through it. I tried SVBONY's red dot spotter and at shallow altitudes of the telescope it worked fine for bright objects but as the scope's altitude goes up, the neck pain does too. This little RACI finder scope is your neck's best friend. It's easy to find objects in the sky and easy to adjust. I agree it would feel more solid if it had 3 screws to adjust rather than 2 screws and a spring but I've bumped it a couple of times and found it was still aligned. I did notice very little difference with the focus adjustments but it feels fairly clear anyway. If you normally wear glasses but don't use them when observing, this is far better than a red dot spotter. For a red dot you have to wear your glasses to use it. No need with this RACI finder. Just go from the finder to the scope eyepiece.

On first looking through the eyepiece I saw that the cross hairs were badly out of focus. Also, the outer part was in focus more than the inner part, meaning the field of view was strongly curved. On disassembling the eyepiece I found a typical symmetrical Plossl but with one of the elements flipped, and with the spacer ring in the wrong place. Reassembled and now everything is fine. A shame because the mechanics of the finder are very good. Nice even multi-coatings as well, and blackened lenses. For reference, here is the proper order of elements. The two lenses in the eyepiece are both achromats and are interchangeable. Cross hair field stop -> long spacer ring -> front element with curved side facing eye -> short spacer ring -> rear element with curved side facing sky. In this configuration the curved sides face each other across the short spacer ring. Edit: I am editing this review because Svbony read it and offered a full refund. I declined this, because now it works perfectly, I mean really perfectly, with a spectacularly good eyepiece when assembled correctly. That they offered it was a big big plus for this vendor.

I wanted a smaller RA finderscope on my Celestron 8SE to go along with a reticle finder. I didn't want anything too heavy and big since I now have two finderscopes on the SCT, and this is perfect. The view is clear and sharp. The objective is only 30mm as opposed to 50mm so the view will be smaller but it is accurate and is a good addition to the straight through reticle. It is metal and well made, and is black with red accents. I very much recommend this is an additional finderscope on your setup. If I was only using one finderscope, I would opt for 50mm, but with two, this smaller one is perfect. Product came well-packed.

This style of finder has become my favorite. I find them more comfortable to use than a red dot or straight through. For me, there was a learning curve moving from a red dot or straight through to the angle finder, but the angle finder is actually pleasing to look through. I've gotten to where I can generally aim to within 7 degrees of a bright object without a finder, and the angle finder makes navigation from any bright object to your target object a cakewalk. For reference, of the seven stars that make up the big dipper, nearly all of them will fit in the field of view with their neighbor big dipper star. In fact, Alkaid and Mizar are about 7 degrees apart. With a star chart(stellarium for me) and a bright star, nothing is too hard to find. It also helps that up is up and right is right through this particular finder. Once you become familiar with the various micro asterisms scattered about the constellations, you'll be hopping from target to target with ease. Sometimes I will adjust the finder so my target falls off center, unobscured by the crosshairs. This is fun to do when splitting doubles; I can view the merged double through the finder then look through the eyepiece to take in the split pair. To sum it up, using an angle finder is an enjoyable way for me to find celestial targets and learn the night sky in the process. It's as comfortable to be at the finder as it is to be at the eyepiece, and the orientation of the night sky through the finder matches the star chart.

Buen material pero algo pesado para montarlo en un maksutov 127 con la montura AZ GTI skywatcher

Does not come with dovetail holder, but fits most standard dovetail holders. Extension arm is good length (approx 4” or 10cm) to provide clearance for your head to have room to use right or left eye for viewing without contacting your scope body. Easy to realign if required after bumping by accident. Cross hairs are properly perpendicular. Using red ring, it can be refocused to your preference and locked. Got mine when on sale plus applying an additional discount coupon. Good deal for quality of unit. Diagonal mirror is very clear and the unit is very lightweight and made mostly of metal with some plastic. Looks like good quality and goes with other Astro gear very well. Viewport diameter is under 1” and topside aperture is just over 1.25”. Can see clearly through viewport but no rubber ring for glasses. Comes with two lens caps. A good product so far.

This item is well made, the optics are clear, and all the components are of good quality materials and construction. I'm using it with my Celestron C5. The right angled view makes it comfortable to use not matter what angle the telescope it pointing.

As described

Standard dovetail mount, works like a charm on my ETX-125PE with a simple worm gear hose clamp all the way around it. A GREAT addition, and it's significantly lighter than an 8x50 unit.
