GS PAPO Leitfernrohr

Belle conception, je l'utilise pour imaginer du ciel profond sur un setup de voyage, je suis très satisfait.

This guide scope is super cute, sleek, and delivers excellent performance. I have it mounted on top of my William Optics MiniCat, and it works wonderfully. It's easy to see why this product comes so highly recommended by so many people!

Ich habe mich für das GSS 250 entschieden, da dies in der Kombination mit der Brennweite meines Teleskops, die besten Werte versprach. Ich wurde nicht enttäuscht. Ich hatte noch nie so ein gutes Guiding.. Durch den eingebauten Flattener sind selbst um Guidescope die Sterne bis in die Ecken scharf. Die Verarbeitung ist großartig ich kann es nur empfehlen.!

Excellent pour guider un C8 avec un RMS total de 0,35 à 0,40 avec une caméra Toupek G3M678C.

My GS-250 has certainly improved guiding as I am able to get much smaller, well-focused stars. The focusing mechanism was rough out of the box, so I opened it up and put a blob of Superlube on the worm gear, and made some mechanical adjustments and it is now very smooth. The only other issue I've had is that the 'shoulder' on the end of the draw tube is too small to stop my filter drawer, so I can't attach it. I have not used the GS-250 photographically yet, but I hope to. Overall, I'm happy with the purchase!

Excellent guide scope at a great price! Only suggestion is to provide larger mount rings so the end user can align Guide and main Scopes.
This is a must for longer focal lengths and Planetary Imaging.

The GS PAPO 350ar Guide Scope impressed me right out of the box. The build quality is very good: it feels solid and well finished. The optical quality is just as good, with sharp, clean star images across the field. I've already used it under the night sky for guiding, and it did the job reliably and without any problems. I'm completely happy with this scope and would recommend it to anyone looking for a dependable guide scope.

Malheureusement impossible de pratiquer actuellement avec un ciel bouché, j'espère pouvoir shooter bientôt.

I do really love this scope. Nice for guiding as well as taking some images with an imx585. May not be 100% perfect but considering the price the value is great.

Probably the most inexpensive triplet available. I use mine for visual and afocal astrophotography. Pretty happy with the results.

Very solid and well-built guide scope. Optics are clear, focusing is smooth, and it holds the focus rock-solid throughout the night. Excellent performance for guiding, highly recommended!

Ecellent guide scope. I know some people want to use this as a refractor and that might work for them but I would not use it as a refraktor with my gear. I think this excels as a guide scope with good optics and excellent performance. I have had much better guiding using this scope.

Definitely one of the best guide scopes I've ever had and it finally has real focusing system!

I wanted to upgrade my guide scope to something easier to focus and I found the prefect fit with the GS PAPO! Not only is it a good guide scope, but still work well as a travel scope, too.

Really good guide scope for the money. Nice variety of FL/apertures so it's easy to find a scope that works with your rig

Works great. Great star shapes.

The GS PAPA 350 guidescope is the best I have used, surpassing the Skywatcher EVOguide 50 and the Stellarvue and Starfield offerings.
It provides excellent guiding for my Celestron HD edge 9.25 at its full focal length of 2350mm.
I appreciate the full range of focuser travel. I have the Crayford model which is more than enough for my guide camera.

This guide is very well made and the use of a rack and pinion focuser is especially helpful. I can smoothly focus the guide scope without the image distorting vibration one gets with the usual helical focusing guide scopes.

The sharp flat field makes this an excellent wide field imaging refractor for someone getting started in imaging. The small size and weight means this is a great travel scope as well. Overall, I think the GS350 is a fantastic product and I can highly recommend it.

I was happy to see a longer focal length guide scope with a focuser so I bought the 350. Now that I have had it for a while I've noted couple of issues with it. First, the OTA seems appropriate for the price point. However, with a focal length of 350, this scope should have a fine focus knob. I found it hard to get it into focus with the focuser. As a result, I thought that maybe their AAF would make it easier and also allow me focus my guide scope remotely so I bought one. This where the problem comes into play. Their installation instruction state that you need to remove both focus knobs to install the AAF. When I did this, one of the bearings and focuser rod fell out and when I reinserted the rod, the other bearing came out. I tried to press fit the bearings back in but the tolerances are too loose and so they just come out again. As a result, I had to carefully superglue them in place (being careful not to get glue into the bearings) which has worked so far. The other issue with removing the knobs is that you can line up the hole rotationally but I had a hard time getting to the set screw on the focus shaft axis because the set screws are at the lateral edge of the accesses hole. A larger access hole would be helpful.

guide scopes with focusers!!! amazing! solves a pet peeve of mine with the plethora of push/pull focusing guiders or with threaded front elements ... nice that it also is M42 threaded!

build quality it truly top notch ... I'd buy all of them if I didnt already have quite a few guidescopes ...

Great quality in workmanship. Optically excellent. The design that allows to expand the scope tube instead of adding extenders at the focuser is fantastic. However, it does not work with the AAF as advertised. The AAF includes 19 mm OD couplers but the focuser shaft insertion hole is 12 mm ID. Touptek should include the right size coupler for the GS AR series guidescopes or change the advertisement.
