  • 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.

How to Use a Guider Scope as Telescope

Test 1: SV106 Guider Scope & 68 degree 20mm eyepiece

As the SV106 guider scope focal length is 190mm, so it works with the 20mm eyepiece, the magnification power is 8.5x. 

I could see the building clearly with adjust the back focus distance 30mm. the words on the building is very clear.

Test 2: SV106 Guider Scope and SV105 Camera

 

I tested the SV105 camera with the SV106 Guider Scope, use sharpcap 3.2 on windows 10 computer. 

Just put the 1.25 inch camera into the SV106 scope double helical focuser hole directly, and adjust the backfocus distance, until get a clear image on the computer. 

I focus the SV106 scope to the outside building, and take this picture with the Mi 5, actually the picture is much clear on the computer screen, when I take this picture on my smartphone, then it is not that clear as see it directly. (I am sorry about my photography skill.)

Test 3: SV106 Guider Scope & 2x Barlow & Diagonal & Eyepiece

 

As I post in the facebook group, I could see image clearly through the eyepiece directly, but the image is not that clear as TEST 1 results. 

Because when the light reflected by the Diagonal, and go through the 2x barlow, it has been loss some. 

As you want to use the 90 degree diagonal with this SV106 finder scope, yes, it would work. 

But if you want to see the much more clear image, I don't recommend you to use the Barlow and diagonal. Thanks very much!

you can mount the SV106 and the dovetail slot (F9144C, F9144D) to the dovetail plate (F9143C or F9143D).
