I like to use this one: Take a dime and hold it out arm's length, noticing its diameter. Now imagine pushing the dime 2.5 miles away. The diameter of the dime at that distance is one

Hi Gang, One of the great new features in APCC v1.9.x is Dec Arc Tracking. There was some discussion when v. 1.9.x was released, but there were many other subjects for discussion as well. In the

@Nicolas, to clarify: The GA run shown here was done through the main scope, not the guide scope? So the guide scope connection is not the cause of these DEC jumps...? Of course, guide camera

I have the same problem, no matter what combination of settings I use, APCC always reaches its meridian limit a couple of minutes before SGP, causing the SGP session to abort. I had a similar issue

thank you I will check I am certain it is not 6 screws. It is the standard finder bracket included with the Explore Scientific telescope. I have always thought about this setup being subject to

Nicholas, Please show us several good pictures of your guide scope setup including how it's mounted to either your main scope or mount. Does your guide scope bracket have 3 or 6 thumbscrews

Hi Nicholas I'm a little confused/concerned about these large and fairly instant jumps in DEC I see it happened a couple of times. I don't see it affecting RA, so it looks to me like something is

Hello Nicholas, The good news is that your mount is working fine. Both the RA periodic error curve and the Dec backlash curve are well within reason for this old mount. I don't see any sign of

When we had this problem, it was one of the handpaddle batteries. Call George at AP and he can send you the right part. If I remember correctly, it was the wired battery. Jodi

Would love to see a picture of the side by side setup. I have thought of doing something similar with my 900. Thanks, Scott

Sorry i'm a bit late to some of these comments >>>>Another very important thing to know about PHD2: If you manually rotate the camera after you calibrate PHD2 you need to calibrate it again. If you

SkyTrack 1.5.1 is now available with continuous tracking for those mounts capable of it. I am trying it out inside with my Mach2, and it seems to work very well. Of course, the real test will be

I wish it was that simple. Michael Best wishes, Michael

Fernando, Not only did I loosen the clutches, but I then retightened them. This rig never moves out my observatory! Michael Best wishes, Michael

>in case you are wondering the GA was from the main imaging scope but now guiding is being performed w the small guide scope For these tests it really is best to keep everything the same (i.e. don't
