Ah, I adjust min movement before a guide pulse is sent, and RA aggressiveness down - yo yoing is my main enemy.
With that said I re-balanced the scope - two 5kg weights were a cm too far down I reckon - now even a 10 minute unguided shot at 2300mm focal lenght looks far better - given across is 30 arc minutes - I'd say under 20 arc seconds of drift in RA - huge yah!
My choice of autoguide camera - a DSI on a 1500mm focal length MAK is probably now limiting me. Have a look at a guided 10 minute versus unguided 10 minute at 5 second PHD adjust intervals on a real faint star. Only a botched levels and curves applied here - look for stair trails.
Surprising the unguided one is on the left! I'd say re-balancing the shot so far has created terrific results for me! Now if I could juist autoguide better
