Product Overview
The SVBONY SV179 dovetail is a red dot finder on a dovetail base (item W9139B) that slides into a standard finder shoe. It projects an LED dot onto a non-magnifying window, so you aim the main telescope by placing the dot on your target with both eyes open. Brightness is variable from a side rotary control that also switches it on, and the sight adjusts up/down and left/right. It weighs 70.0 g.

Who It's For
This is a good match if your telescope has a dovetail finder shoe, as on Celestron 80EQ, 80DX, 90DX, SE, SLT and Omni series scopes, and you want a replacement or a quick-aim finder.
Key Features & Design
- Red dot sight: fast, precise aiming at celestial or terrestrial targets.
- Adjustable brightness: suits dark skies and brighter conditions.
- Wide field of view: unmagnified, so targets are easy to find and follow.
- Dovetail base: slides into compatible finder shoes.
- Light, durable construction.



Recommended Uses
- Target acquisition for the Moon, planets and bright stars.
- Alignment star selection for computerised mounts.
- Daytime terrestrial aiming.



Compatibility and Accessory Notes
- Fits: SVBONY lists Celestron 80EQ, 80DX, 90DX, SE, SLT and Omni series telescopes, among others with a matching finder shoe.
- Two-hole version: for telescopes with a two-hole finder mount, SVBONY makes the SV179 with a two-hole base as a separate item.




Good to Know Before You Order
- First use: pull out the clear plastic battery-isolation sheet before switching on.
- Base type: the dovetail suits telescopes with a finder shoe; if you are unsure which base your telescope takes, send us the model and we will confirm.
Frequently Asked Questions
Is it difficult to set up?
No. Slide the base into the finder shoe and tighten the shoe screw, then in daylight centre a distant object in the telescope and adjust until the dot sits on it.
How is brightness set?
With the rotary control on the side, which also turns the finder on and off.
Does it magnify?
No. It is a 1x reflex sight with a red aiming dot.
Bottom Line
In short: a 70 g dovetail-base red dot finder with variable brightness for quick, unmagnified aiming on Celestron-style finder shoes.
