***UPDATE*** (January 6, 2024): I beta-tested a new version of the QFocuser firmware and ASCOM driver, and the dozen-or-so problems I reported to QHY have all been addressed! I expect these new versions to become available on their web site very soon.
Thanks a lot for volunteering to be an alpha tester for this product. I really think that your use case is very relevant to almost everyone who has a large refractor or a small reflector. Considering how trivial a focuser is, both on the hardware and on the software side, I am really impressed that they manage to pack that many annoying and totally unnecessary defects in their solution (vibrations in stepper motors, delayed position updates, and hard coded configuration values are all very impressive achievements in 2023 :-).
Great that you raised a ticket with QHY. I’ve been considering this focuser and will wait to see if QHY successfully addresses your concerns. Great review, thanks. 😊
Julien - you rock man! This is an awesome video and exactly what I needed. Where have you been? Anyway - I am a new subscriber and will be watching all of your videos! Thanks!
Just ordered the precision version. It should sit on the other side of the scope which helps with portability for me. The ability to manually change focus might be a game changer for astrophotographers who want the focuser attached but switch to visual without having to disconnect the focuser.

Good luck! QHY hasn't tried to update their Polemaster driver in years, despite multiple complaints about the video feed locking up. But thanks for the focuser review - a nice new product if the driver ever works.
Great video and improvements, I do think 1 part is missing for me which is a bit of a general inspect on the focuser, the connectors, usb, 12v, etc..Not sure if I somehow missed that.
QHY has typically had great hardware. The downside is their driver software has also typically been less than ideal which made their other wise excellent hardware a non-starter for many. YMMV
It's unbelievable to me that QHY didn't implement the isMoving() property for ASCOM!! Certainly, they are counting steps during the move. Perhaps the driver blocks until the move is complete? They more than likely don't implement the Halt method either. Seems like a huge oversight. I'd be interested to see how you physically measured your backlash with dial gauge. Thanks for the great video!!
They likely have implemented all of those. The problem is probably with the firmware. The very first version of my OAG focuser had the same problem. It took some thinking to figure out how to implement the firmware to allow for querying of the position while the stepper was moving, but it’s not that complicated. Anyway, I’ll keep you guys updated. CS!
Finally. A review by someone technical. I appreciate all of your deep dive here. Also, the difference between one person building an OAG ASCOM Focuser in their Garage in San Jose versus someone being paid a salary to implement these things as their day job should be evident. Some of these misses seem egregious.
Also, an FYI . . . I downloaded the new Nightly NINA Beta version and could not get the Q-focuser to work. All my other devices connected without issue except for the Q-focuser. I also updated my ASCOM platform but no luck. I went back to the regular release version of NINA and the Q-focuser connected again. Weird.
Very informative review, though a disappointing result. I’ve been considering one, but have had enough history cursing QHY software in the past. Sad they haven’t recognized the importance of good s/w. Will keep an eye out for additional updates!
Super vidéo comme d’habitude et merci énormément pour les sous titre même si ton anglais est parfaitement compréhensible par moi. Tu as le lien de ton soft pour la moyenne de température ? D’avance merci
