[PRejto (Peter)]

So, I've got a top mount (MEII) permanently set up. A TEC180 (so no mirrors flopping about, etc), and a 394 point T-Point model indicating that I'm within .1 tic from the refracted pole in both MA and ME. PEC is on and when last measured was sub arc-sec.

Yet, my Protrack results look crummy.

I see strange little stars growing in the general direction of RA in 5 min Protrack images. 15 sec control images do not show any distortion, nor do guided 5 min images. Why the little "budding stars" rather than just a general streak or egg shape? (X=RA)

I remember reading a post I think by Marcus saying that he needed to modify the RA tracking rate. Might this be the issue?

Any ideas greatly appreciated (while I waste time waiting for my ST-I to be returned).
