I just had my new Orion Atlas Pro AZ/EQ-P out for First Light this past weekend. Short form: I am very favorably impressed. Mine sits on a Losmandy HD tripod via an Optical Supports adapter; for these sessions it carried my TEC 140 w/ a Telrad, SV50 RACI, AP diagonal and EPs up to an ES 30mm 82n. First off, I broke my cardinal rule about never taking untried gear to the field, and this weekend was a three day away star party...I didn't need to worry. The mount fired up, the hand set initialized, and I punched up "AZ" mode (having set the mount up and balanced my scope at home, carefully marking positions). I went for the two star alignment procedure using first Sirius, and then Aldebaran. The alignment was successful so I punched up M42 and the Atlas AZ slewed to it and dropped the Trap near the center of my 24 Pan - the first time I ever used it. The Go To performance was consistently very good and it tracked like a bloodhound. For one test, I centered Jupiter in a 19 Pan and left it for an hour and a half. When I came back it was still in the field of view. Not too shabby. My biggest surprise came early on Sunday morning. We had been observing Saturn and I had a Pentax 5mm XO in the focuser. Without thinking about it, I slewed the mount over to see M3 and only remembered the 5mm XO after hitting the button. Much to my surprise, M3 was split in half at the edge of the FOV. Again, I was impressed. I did not disable the encoders (which worked just fine near as I could tell) and had no issues with degraded Go To performance. So all things considered, I was mighty happy about the performance. There are a few twitchy issues I would like to address. For one thing, I'm not crazy about the saddle, it's short and I just feel uncomfortable about it - I'd rather have an ADM dual saddle there for my peace of mind, but I have to admit it got the job done. There is also some wackiness with the power cord. It seems like, under some conditions if too much slack comes out of the cord, the mount will reverse direction to hit the target. I'd swear this happened at least once, but I'm not sure what is going on. And finally, of course, the hand set cord is way too short. Really? C'mon Orion, can't we have a big boy cord with our hand set? But I like the GoTo and tracking performance, the screw in power jack, ease of set up and balancing, improved elevation screw system, and the way it fades into the background - it's sooo quiet. Hope this helps, I'll have more to say with use and the chance to try it in GEM mode.
