I think the alignment in Dec is a bit off.

Thanks
Gee I’m amazed your getting perfectly round stars with those numbers especially when Ra is nearly double Dec
I cringe when I’m above 1 arc sec on my EQ6-R pro
I’m assuming that your getting some PE in Ra or random spikes in Ra which would undoubtedly cause some star bloat ??
In my capture software APT, when each sub is displayed on the main screen, there’s also a series of thumbnails on the right hand side which is zoomed way in to the centre of the frame and you can see whether an Ra spike in PHD2 has caused star bloat or an irregular shaped star etc... in other words your accessing during the imaging session how your guiding is running ( without looking at the PHD2 graph , guiding numbers and star profile tool ) just by looking at these zoomed in thumbnails
Do you balance East heavy or pretty much even balance ?
Cheers
Martin
