Greg, Polemaster is to align the polar axis of the mount correctly. Nothing less, nothing more. To correct for cone error and/or align the scope to the sky, other routines are necessary but the

Cone error is an error that is in your telescope. It is NOT an error that is in the mount. Pole master is not attached to your telescope where the cone error exists. Pole master has no cone

I’ve been trying to understand why PoleMaster isn’t working for me. It seems like the procedure would insure that the mount is correctly aligned but the scope itself could still be off a bit due

I believe Pole Master works regardless of cone error. Roland

Sounds great. I've never been able to get PoleMaster to work. The best I can do is about 8' off (so I use PEMPro). Do you think it could be because of Cone Error? Greg

Cone error correction. There is an easy way to detect it. In this new keypad routine, you simply go to a star on one side of the meridian, center it and press Recal. Then send the mount to a star the

Cone error correction? or detection? Greg

We will have a cone error correction in our upcoming keypad software. Roland

NO! Orthogonality has nothing to do with guiding. Roland

Another name for orthogonality error is cone error. Site https://www.sharpcap.co.uk/conesharp has another way of describing the problem and software for

Another name for orthogonality error is cone error. Site https://www.sharpcap.co.uk/conesharp has a good description of the problem and software to measure it. Apparently some mounts do allow an

Suresh, I also have a couple of questions about Orthogonality error (OE). I hope you don’t mind me jumping in on this thread. Can OE lead to issues with Guiding? I have continued to struggle to

Hi Tony, By default the mount will flip if issued a goto command after it passes the meridian + meridian delay. However, you can force the flip by setting the Action to take on APCC's Meridian delay

Jimmy, best explanation of OE I have ever seen or heard, great post!

If OE is short for orthogonality error. An Orthogonality error (OE) is only east-west when pointing at zenith or along meridian. OE is always in line with the counter-weight shaft. When pointing at

Hi, While I have been using Voyager successfully for a bit now (thanks Bill :)) I still have not been successful in getting the mount to flip automatically when reaching the meridian. Can anyone see

I know this question was discussed by Roland several years back but I seek the answer . Why does OE always show up on the east west axis Thanks Dr Suresh

Paige from Astro-Physics gave me the part number for the AP-1600 dec sight hole cover, in case anyone else is interested in trying Tony's idea of drilling and tapping a spare. The part number is:

The encoders cannot anticipate wind but can react to it after the fact. So you will have excursions but the axis being affected will recover much faster when the encoders are on. The best strategy is

I have a question regarding encoders and wind. Do encoders make a vast improvement in gusty wind conditions?
