My experience with the M-Uno has been very good, I had struggled with guiding my G11 with mediocre results for years. It was a common site here in the mount forum that I would be asking for assistance. Funny thing is, since I purchased the M-Uno I rarely have to visit the mounts forum. That tells you something about how good this mount is.
I also tried it as a completely stand alone imaging system without computer. I used my phone for Go To and used a Lacerta M-Gen II stand alone autoguider for guiding, dithering and camera control. The M-Uno provided a completely pain free imaging session. Everything just worked!. That's what I always wanted to have in a mount. I also like the fact that in some countries you have the ability to choose if you want Avalon's own StarGo system or the Synta controller which allows you to use Eqmod.
I took these images a couple of nights back. These are the tightest stars I have ever had. The slight elongation on the right side seems to be something in my optical train as it has been reproduced with the camera at different orientations and two different cameras. I think it is badly machined adapter. The color image was via DSLR and the B&W image was via CCD Camera. Both were with 8" Edge HD at f7. The CCD image is a single 20 minute exposure. I am happy with what I am getting.
A bit late to jump on this post, but I'm kind of desperate to find somebody to share their guiding parameters with their MGEN/M-Uno combination. After following all the posts regarding the M-Uno, it seems that I am the first one who had no luck with "plug&play" with this mount... I'm using one with the Synta controller, which I operate from a Starsense hc via a Skywatcher interface. Alignment and PA are just fine. Pointing is more than good enough, but with the guiding I keep on struggling. I used the MGEN before on my AVX with a 400mm guide scope (for all my OTAs ranging from 480 to 1624mm FL). That worked well enough. Just the too many bad images in the long run per session, which I attributed to the AVX's bad backlash in DEC and a general 'lack of precision", made me think of getting something somewhat better. My setup for the M-Uno is a 240mm guide scope in that special Avalon adapter, which you put between OTA and mount. Serves double purpose, because it creates room for all of my scopes to freely move round and over the meridian and also fits the guide scope with a good connection to mount and OTA. Or so I thought... While my results now are mostly reproducible during a particular session, I start getting oval stars in exposures longer than 10 minutes. Even my AVX managed exposures of that length with good results at about 50% of the time...
To cut the story short: Would you be willing to share your MGEN parameters you are using with the M-Uno? Guiding rate, Num, Tol, Aggr and Mode? Your favorite exposure time for the guider? Some brief info about your actual setup would be welcome as well. E.g. which optic do you use for guiding?
Any advise would be greatly appreciated!
Thanks and cs,
