Thank you for your response.
I have used AM5 for RC6, Redcat51 and ED80.
Guiding performance on east has always been much worse for all 3. However, I have just analysed the period, which I had not done earlier. The 1100sec is only for the RC6 - for the others, it has been around 430 sec or so.
Caution - for some reason most of the imaging with those scopes was while pointing west, and the east pointing sessions were short.
I will confirm this by trying the Redcat51 tomorrow and having at least 1.5 hour guiding pointing East. If this continues to be 430 sec, then it would seem to be due to the RC6 load distribution.
Thanks for the question - had completely missed checking the harmonics for the other scopes.
I will get back in a day or so with the results.
To repeat what I had said earlier, I understand I am using it beyond the recommendations. But since it guides so well in one direction, it is natural to want it to guide equally well in the other direction as well :-)
