I have an older CGEM (2006) mount with Celestron wifi adapter. I can get my android phone (LG V20) to connect to the wifi network issued by the SkyPortal, although sometimes with considerable difficulty. I have loved using SkySafari 6 before I got the wifi SkyPortal, so I was excited to try alignment and slewing to my favorite targets, just using my phone as my remote slewing device.
The first time I tried it, I had already aligned successfully with 2 alignment stars and 4 calibration stars. I connected and only used the app to slew the telescope to different targets and it worked pretty well....once. That first night I even successfully aligned using the SkyPortal and the SkySafari 6 app.
The next night was a nightmare, I finally just gave up after 8-10 failed alignments and 6 hours later. I could connect by using connect & align button, set the scope to index marks and align to the first star, all good. Choose and went to slew to a 2nd star, and it ran my scope into its tripod. Or, it will act like it does a successful alignment, and then when you choose a target, it is over 20 degrees off. I align with a cross hair eyepiece on a 2x barlow, I'm pretty sure I was not that far off. Another time it was slewing to a target quickly, and it came to a very abrupt stop and said it was aimed at the target I was slewing to, but again it was over 20 degrees off.
This kind of behavior makes me worry about it damaging my mount or scope. Does anyone have any ideas of what I am doing wrong. I am a rookie amateur astronomer, so I have no doubt that I am the problem, but I really cannot figure this out.
