For those nights when you don't plan to capture astrophoto exposures, this versatile Guide Scope can double as a straight-through finder scope with an optional 1.25" eyepiece installed. For example, inserting a 20 mm eyepiece creates a 9.5x50 finder scope, or you can insert one Illuminated Centering Eyepieces for use as a finder with illuminated crosshairs for easy aiming. (Eyepieces sold separately). Versatile 50mm aperture Guide Scope with a built-in helical focuser for precise focusing of potential guide stars;will help guide you to capturing higher quality astrophotos;an ideal addition to any astrophotographers collection of gear. Fully Multi-coated Glass means multiple coatings on all lens surfaces and all air-to-glass surfaces are anti-reflective multi-layer coated. And double-sided FMC lens has greater advantages than the single-sided in increasing the light transmission, delivering bright, clears and crisps images even in low-light conditions. 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. The focuser (Stroke 30mm) helps you quickly lock to 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. 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. 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). 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.

Tips with SVbony   

Q:What are the outstanding features of the upgraded sv48p?

A:

Toothed focusing knob

Dual speed still, but this time you will find the toothed knob on the scope just you did on our star product SV503. The touch matters in our opinion. These pairs of toothed focusing knobs would make you feel more pleased when you view the night sky with naked eyes. The targets have been located but somehow we just couldn’t make it clear, that might be the last thing we wish to happen in this hobby. So we keep the dual-speed focusing system which makes the whole process easier and smoother and we truly believe that you would love it.

Comfortable damping

We want to achieve a good balance between damping and smoothness with this tiny brass focus plate. So now, a 13mm brass plate under the focusing tube, provides comfortable damping to secure the process of focusing stable and accurate, which means deviation or shaking of the focusing tube, or the inconsistency of the hand feel during the whole operation of the focusing will not be the pain again.

360 rotatable R&P focuser

A rotatable focuser would greatly help you get just the right position for your camera or diagonal without touching multiple screws which could be pretty annoying to the final image. Just loosen the knob on the tube a little bit then you could just rotate the whole focuser, simple and clean.

Mounting rings with a 130mm dovetail plate

A longer dovetail plate than the original SV48 which has a 100mm dovetail plate gives you more space for the mounting, with the fine-made mounting rings together making sure your telescope is steady.

Q：Hello, does this only bring the telescope or does it have other accessories? Can I use it directly after buying it? Do I need to buy other accessories?

A:Package includes SV48P 90500 Astronomical Telescope OTA,2" -1.25" Adapter,Finder Scope Bracket,Lens Cover,1.25" Dust Cover,130mm Dovetail Mounting Plate with Tube Ring

 No included diagonal, eyepieces and a tripod etc.

Q：The description has two different weights how much does it actually weigh？ 

A：7.73 pounds

Q：What type of glass is used in the objective?

A：Fully multil green coated lens; fitted with achromatic glass for good edge-to-edge viewing; fully multi green coated lens maximize light transmission eliminating false color.

Q：are the rings felt lined?

A：Sorry it doesn't, the bracket is fixed on the lens barrel with screws and is detachable.

Q：Is the metal loop telescope holder removable, if is is, how do you remove it?

A：Yes, you can remove it by turning the screws on the bottom of the stand.

Q：How to get started with Astrophotography? 

A: Firstly, you need choose a telescope.For beginner astronomers, a refractor is the better beginner telescope for astrophotography.
Designed for Camera photography
Loosen the screw that fixes the focuser on the telescope, the focuser can rotate 360 degrees.When you use the camera, you don't need to unscrew the camera to adjust the angle.You only need to loosen the screws, adjust the camera angle, and then tighten the screws.
