Steve I have no rings a bolted the dove tail to the OTA with a piece of timber shaped to meet the curve on the inside of the OTA..this is reasonably efficient however I feel I will reassemble it and add glue to the timber (hard as nails or similar) so as to bed the timber on the inside of the OTA... this should fix the flex however some additional brakets will fix it for sure..I opted for no rings simply to keep the weight down... if I like the set up I intend to build a lighter OTA ..my main concern is that it is so big and at the moment the EP sits such that I have to get on a cahir or ladder to look thru the camera..I can fix this by reconstructing the pier but I builtthe thig so strong it will be a job to cut it down...
Also as strange as this sounds I seemed to get more light than I needed... for the stuff I like to photograph.. 200 seconds (unguided is easy) and a stack of 200 second subs is more than I need.. the dark location lets me get a lot ... but you know how it goes one has to have a go because it is there..but in truth I feel the set up for me finally is a good 100mm refractor and 10 minute guided runs... before the pull down I was getting runs of 9 minutes with little attention to correction of RA and those "bumps" may well be gone after the "blue printing"
