I was hoping folks knowledgeable with imaging near Polaris could please share their experience with me. After some time off, I am back to imaging and want to retry imaging at higher latitudes. I once tried to image right near Polaris, but experienced significant field rotation so I never went back to it, but I have since acquired a Polemaster, which is one of the best pieces of kit I have ever owned (mostly because I truly sucked at polar alignment). I am hoping that will help improve my chances of success.
My system is an FSQ106 (fl=530), PhD guiding (have not upgraded to PhD2), Skywatcher EQ-6 Pro mount, and a KWIQ guider.
My questions are:
1. Is there any advantage to upgrading to PhD2 from PhD? It seems to work okay for most of my needs but I can upgrade if it will improve my chances of success, although I dread a night long of pulling my hair out in the field if the transition is not smooth.
2. I recall a parameter somewhere in the "brain" icon for PhD that I need to increase or decrease to improve the calibration within PhD. Do I need to adjust any parameters to get better/feasible calibration?
3. I have read some older posts about imaging "high up" and some have suggested calibrating guiding at a lower latitude and then moving up to the higher latitude. Will PhD be able to correct for the change in latitude?
4. Any suggestions on where to pick a guide star? Some older posts have suggested to pick on in the middle of the field of view, but given my setup I am not sure how to make that happen as I cannot tell where I am with my guide scope (there is a camera on the back of it).
5. I tend to acquire 10min subs for luminance. Will this be possible, or will I have to lower my expectations and back this down to 5min to avoid elongated stars.
I am hoping the addition of the Polemaster helps tremendously.
Thanks for any guidance you can give as I begin to kick the rust out of my acquisition methods.
