SVBONY SV208 8x50 Correct-Image Illuminated Finder Scope

Product Overview

The SVBONY SV208 is an 8x50 correct-image finder scope with an illuminated crosshair reticle. A 50 mm, two-element achromatic objective with full multi-coating and a 185 mm focal length gives 8x magnification, a 7.3° field of view, a 6.25 mm exit pupil and 21 mm of eye relief. The LED reticle illumination has adjustable brightness and runs on two LR754 coin batteries. The eyepiece and objective focus separately, and the net weight is 632.5 g.

Who It's For

This is a good match if you want a larger finder that shows fainter stars than a 6x30, with an upright, correctly oriented view and a lit crosshair you can see against a dark sky. It suits star hoppers working from charts, and imagers who want to centre a target quickly before plate solving.

Key Features & Design

• 8x50 optics: 50 mm achromatic two-element objective, 185 mm focal length, 7.3° field.
• Correct image: upright and not mirror-reversed, so the view matches a star chart.
• Illuminated optical reticle: LED illumination with adjustable brightness.
• FMC coatings on the optics for light transmission.
• Separate eyepiece and objective focusing: focus the reticle to your eye, then focus the stars.
• Angle adjustment for aligning the finder to the main telescope.
• 21 mm eye relief and 6.25 mm exit pupil.

Optical Design

The objective is a two-element achromat. With 50 mm of aperture at 8x, the 6.25 mm exit pupil delivers a bright view and reaches fainter stars than a 30 mm finder, which helps when the next star on your hop is below naked-eye visibility. The correct-image optics keep the view upright and unreversed. Because the eyepiece focuses independently of the objective, the illuminated reticle can be made sharp for your eye before the sky is brought to focus.

Recommended Uses

• Star hopping to galaxies, clusters and nebulae from a chart.
• GoTo alignment on bright stars before handing over to the main telescope.
• Centring imaging targets before plate solving or guiding.

Compatibility and Accessory Notes

• Power: the reticle illuminator uses two LR754 coin batteries.
• Mounting: SVBONY's product page does not specify the bracket or shoe type. If you need to confirm the fit on your telescope's finder base, contact us before ordering and we will check it.
• Payload: at 632.5 g it adds front-end weight, which is worth balancing on smaller mounts.

Good to Know Before You Order

• Batteries: the illuminator takes two LR754 coin cells; SVBONY's page does not state whether they are included.
• Size: an 8x50 is larger and heavier than a 6x30 finder, at 632.5 g.

Frequently Asked Questions

Is it difficult to set up?

No. Mount it on the telescope, focus the eyepiece until the reticle is sharp, focus the objective on a distant object, and use the angle adjustment to line the crosshair up with the centre of the main telescope's view.

Is the image upright?

Yes. It is a correct-image finder, upright and not mirror-reversed.

Can the reticle brightness be changed?

Yes. The LED illuminator has adjustable brightness.

How wide is the field?

7.3° at 8x.

Bottom Line

In short: an 8x50 correct-image finder with a dimmable illuminated reticle, FMC optics, a 7.3° field and separate eyepiece and objective focusing, for finding and centring targets with a view that matches the chart.
