About this product

Model:  sw9x50raefinder
Part Number:  20934

Upright image with completely corrected left/right image orientation.

Sky-Watcher's 9x50 Right-Angled Erecting Finderscope provides an upright image with completely corrected left/right image orientation for more comfortable and convenient operation when compared to a traditional straight-through viewing finder. 

The achromatic 50mm objective delivers good light gathering, a wide 45° field of view and a cross-hair reticule for easy navigation.

The 50mm aperture is genuine, it is not stopped down like some cheaper finderscopes.

Easy to setup and easy to use. The mounting bracket fits into standard finder shoes from Vixen, Sky-Watcher, Celestron, GSO, etc. Additional finder shoes are available separately.

To attach this to a Celestron SCT you will need a Baader Quick Release Finder Base.

To focus the finderscope simply unscrew the lock-ring, rotate the objective, then re-close the lock-ring.

Easier to use
Monday, 17 June 2019  | 

I bought a straight through finder at first. I found it confusing to locate my target with the image being upside down. In fact with a basic photographic set up I missed my target altogether several times. I have only tried my new right angled finder scope in alignment with my telephoto lens but I can see already that it is much more straightforward. I hope this will be repeated in the field but the weather has been so poor lately I have not had the chance to test it. It lacks LED illumination and I could not seem to purchase such an option which would have been better.

This is an other excellent product from FLO, the field of view is excellent with this finder, and when you get the hang of it you will have no problem finding objects in the night sky. Delivery service was excellent from FLO as usual. Thank you FLO

Great peice of kit

I bought this to replace the straight unit I had on my dobsonian, this makes life much easier as I don't have to lay my face against the telescope.
The only issue is that it is not easy to see the cross hairs against faint objects but this is a small problem considering the cost and quality of the unit.
I would recommend this item.

neck-saving finderscope
Monday, 25 June 2018  | 

bought this finderscope because my neck problems are worsening with straight-trough finderscopes. this finderscope is perfect to relieve these problems. Will replace all my other finderscopes with these type finderscopes eventually. simple but efficient ! recommended.

That was very handy as is very easy for my Sky Watcher inter changeable of finderscope lenses now to spot with out bending down as with the straight finder, The settings are not lost when changing over on the Vee Slide on the Telescope itself

This had made my entire astronomy hobby so much more comfortable. Not only can I scan around knowing what's up down left and right, I can do it in s comfortable position. Sits perfectly on my 150p and has helped me find loads of new objects without breaking my back.

Awesome finderscope
Tuesday, 30 January 2018  | 

Puts my old 6x30 straight-through finder to shame. Much brighter so useful for DSOs and having an erect image is intuitive. My one criticism is that 9x mag is almost too powerful. 7x would make it easier to locate the target. But this is a minor issue.

This 9x50 finderscope is probably the best accessory I've acquired. Incredibly comfortable compared with the miserable 6x30 straight through that I've just thrown away.
I also have to mention the people at first light optics for their help and courtesy, whose assistance made the purchase a pleasure.
5 stars all round!
