Re: Best Way To Determine Periodic Error?

Hi Arun
i posted pretty extensively about?my experiences with unguided imaging:
Although I have to admit i do not remember if I did PEC!?
Unguided really depends on the things mentioned in those threads, your focal length, imaging time, imaging resolution, and expectations. I think my tests had very positive results.
In general I highly recommend PEC, even if you are guiding. I've done PEC via PEMPro on a handful of mounts over the past few months and I saw the primary PE drop considerably (like by half).?
It does require some understanding of PEMPro, someone else in another forum (Jim?) was asking about this and I really should do a tutorial. it's not hard, but there are some things to keep in mind that make it a lot easier
Brian
Has anyone tried PEMPro and found implementing a PE correction to make a meaningful difference in tracking? It seems like it should, but it also seems like PHD2 should be able to correct a long period low amplitude PE all by itself.
