Hi,
I’ve bought am3 and was able to test once on a windy night with 2h clear window. I also forgot to secure the latitude adjustment locks but still excluding big spikes at the beginning and end of session I got around 1” RMS. The load is c.a. 4.5 kg (mak127 plus 189fl 50mm guide scope).
I’ve been reading posts about periodic error and started drawing lines on my report and calculated steepest slope error at c.a. 0.22 arcsec/sec. I’m attaching my report - I’m worried about the spikes on the graph - should I be?
