I have the asi294mc pro on the edge 11 with oag and 174mm mini guide camera.
On some warmer nights (72F and up), i've left it at my usual -10C cooling target, but im noticing a hot spot early on in the imaging session, maybe the first 20 minutes (i should be equalizing longer, forget how long though, anyway, its a nexdome).
Is this pretty typical to see this type of pattern near the center (nina with extreme stretch going on, raw image, frame)? Also, wondering what typical max speed fan target I should shoot for to avoid added noise, i want to say it was 65%? After about 15 mins its at 67% for -10C (all my darks/flats are at -10C as of now).
Thanks in advance for any info, though i think its just a cool down period thing
