What would be the ATO max focal length that you would use this guide scope with?
I need to know the specification for the objective lens to the focal plane (true backfocus). The 45mm cited is is focus travel, not backfocus.
Why is the video showing an ota on a 20 dslr tripod?!?
I'mlooking for recommendations for mounting to my ota w 90mm outer diameter...any ideas?

Best starter guide scope

Works just as well as $200 guide scopes, and for only 50 bucks, it’s definitely worth it. I can get guiding under 1 arc-second. Focusing can be tricky, but once it’s dialed in it performs perfectly. (I did 3-D print a due shield for it but it’s not needed.)

NO agregas mucho peso a la montura con este pequeño tubo guia.

Lo uso como tubo guia y me da muy buen resultado. No agrega mucho peso a tu montura y te permite hacer exposiciones mucho mas largas.

Good Choice

Good quality used for guide scope and it did what it was supposed to do.

what to expect

This little guide scope works great. Just know you basically have to unscrew the front end and barely put it back on if you want it to be in focus. Great beginner guide scope to grow with. If you are like me and live in the southeast make sure you buy a dew heater for it. gonna be a little adventures and try using it as a main scope one night to see what happens. but as for using it for guiding hands down greatest bang for your buck

Great

Really easy to focus, and works really well. For the price, it is a great buy. I have attached an image I took using it (as a guider)

Works Great

The 48mm tubes was the perfect solution for the long focus tube being out too far...

Can't align with telescope

While compact and lightweight, the main issue I have with this guide scope is there isn't a way to adjust it to perfectly align with the telescope. As a result, whether you are using it visually or with a guide camera, what you see through this finder/guider may not match what you see through the telescope, thus rendering it relatively useless unless you are using a very wide FOV telescope.
