30/35mm Back Focuser

The focuser (Stroke 30/35mm) helps you quickly lock the stars you want to see. The focuser simply moves the attached device inwards or outwards while maintaining its orientation, which means your field of potential guide stars will not rotate as focus is adjusted, further increasing ease of use.

10mm Helical Focuser

After focusing, you can see details of the image clearer and brighter. The focusing accuracy is up to 0.1 mm. The 10 mm focusing stroke will meet your needs for viewing guides.

M42*0.75 & 1.25inch

The Multi-Use Guide Scope features male T-threads on the focuser collar for secure threaded attachment of guide cameras equipped with female T-threads.

And the versatile Guide Scope can double as a straight-through finder scope with an optional 1.25" eyepiece installed. For example, insert a 20 mm eyepiece to create a 9.5x50 finder scope, or insert one Illuminated Centering Eyepieces for use as a finder with illuminated crosshairs for easy aiming. (Eyepieces sold separately).

Fully Multi-coated

Fully Multi-coated Glass means multiple coatings on all lens surfaces and all air-to-glass surfaces are anti-reflective multi-layer coated. And FMC lens has greater advantages in increasing the light transmission, delivering bright, clears and crisps images even in low-light conditions.

Stray Lights Elimination

The elimination design improves the observation efficiency since less light is lost due to reflection and improves the contrast of the image by elimination of stray light.

Meticulous Design

A compression ring fitting keeps any inserted autoguider cameras or astronomy accessories free of pesky scratches. CNC machined aluminum alloy body with laser engraving letters has a long performance life.

Metal Hoop with Dovetail

The Multi-Use Guide Scope features a machined, knurled metal hoop to make fine focus adjustments nice and easy, while a thumbscrew lets you lock-down the focuser in-place once to complete adjustments. And the plastic on the endpoint keeps the scope itself free of pesky scratches.

Specification:

SVBONY UHC 1.25'' Filter for Astronomy Telescope Monocular Eyepiece Observations of Deep Space Object

Basically, it works by darkening the background so you can see more nebulosity that would otherwise be too faint.
​This filter has allowed one to actually see some small planetary nebulae that would otherwise be too washed out by the background to be seen, and I'm able to see more detail and more of the dimmer fringe of larger nebulae like the Orion Nebula, the Dumbbell Nebula, and the Lagoon Nebula.
​It helps with finding the little planetary nebulae because it dims everything but the nebula, i.e. you can look at the same spot with and without the filter, and with the filter in place the stars are dimmed somewhat but the nebula isn't. The nebula is the dot that doesn't get dimmer when you thread in the filter. It works well at both low and high powers, too.

Features:
1. Brand New SVBONY 1.25" UHC filter.
​2. This filter is perfect for observation of faint and low-contrast deep-sky objects. These features make it perfect for observing nebulae and other deep-sky objects.
​3. Barrel diameter: 1.25'' simply attach to eyepiece-cased in a sturdy transparent case.
​4. Significantly reduces light pollution, great for city and suburban observation.

SVBONY 1.25'' UV-IR Cut Filter Telescope Optics Infra Red Filter CCD Camera for Astronomy Monocular Binoculars Telescope

The SVBONY filter is a better choice for all digital imaging with digital cameras;DSLR camera;CCD cameras;modified Webcams and telescopes.
​The UV-IR-Cut filter uses the very latest coating technology to deliver the high filtration quality and lifetime durability.
​The UV-IR cut filter combine with any of the other Baader filters screws into the back of the eyepiece or camera adapter to block out the chromatic aberration unwanted.
​So it delivers the sharper images possible;it can also reduce the ghost images caused by IR radiation

Features:
1. True optical quality glass substrate and coatings.
​2. Very low reflection multi-coating, Striate-free, and plane-parallel substrate.
​3. Combine with any of the other Baader filters, to deliver the sharpest images possible.
​4. Standard 1.25 inch Filter threads for 1.25" eyepieces and other accessories.
​5. Comes with a plastic box to keep it safe and clean when not in use
​6. Interface Threads: M28.5*0.6.
