Alex I have always had a love hate relationship with OAG's. I love the idea but hate them in practice (I have 3 of them now all different types gathering a lot of dust
). I am trying to set up a nice grab and go kit using a sphinx SXW for the mount with a little F6 meade 5000 80 apo. I have a side by side setup which I use with a ZS 66 as a guide scope with the QHY5 and this allows me to keep tracking inside 1 pixel deviation in MaximDL. Unfortunately the telescopes and camera weigh 7.4kg which is right on the 2/3rds limit for the mount so it really does not handle the wind well. I really want to get the OAG to work for me (~ -3kg) but am not happy with it's performance so far (i.e. fiddly @#$%^&* ). So I either buy the SXD and chuck a FLT 98 CF (3.8 kg) along with the side by side setup or get the OAG working. What method did you use to determine the field of view settings in SN??? I am not ready to give up yet
