A new Polar alignment technique using BYEOS

[STEVE333]

Below is a link to a YouTube video showing how to do precise polar alignment using BYEOS.  The technique is easy, and, I hope it helps you as much as it has helped me.

I have always achieved misalignment errors of less than 1 arc min with this technique with only one iteration.

 

Happy aligning!

Hi Steve

 

  I ran the spreadsheet again using the last images I used for the spreadsheet.  I clicked on 'beyond P26" and got positive numbers.

 

  I will try this next time I get the opportunity and let you know how it goes.

 

  My comments on AstroCursor still stand ... Yes I did it again.

Hello Steve

 

  I had some time and clear skies last night.  I used your method for quick alignment and had the results described in your posts.

 

  I can't comment on how close the alignment was because visiting with neighbors and set-up goof-ups took up a lot of time.  I didn't get to spend too much time imaging to see how the PHD2 numbers were over a long time.  I did take a 7 minute guided exposure of M45 that came out good.

 

  I did have better numbers in in PHD 2 over last time I set up using your system.  Dec was below .5 arc seconds most of the time and total was below 2 arc seconds most of the time.  I will continue to use it and have a final evaluation at a later date.  I have several scenarios to try first.

Hi Ron -

 

Just a short clarification on your comment

 

 The atmospheric modeling seemingly has to have a specific camera orientation to be effective.  Something I dont understand but accept.

 

The atmospheric modeling will work for any imaging camera orientation, so, you can orient your imaging camera any way you wish.  The atmospheric correction is only applied to the mount's Alt and not the camera's orientation.

 

Hope this makes sense.
