A star to guide me by Posted March 5, 2017 Share Posted March 5, 2017 When setting up my 8SE I found the image drifting slowly as I tried to reconcile the star pointer with the scope image. Balancing the tube helped but it seems a crude way of setting up a precision instrument. Any advice to reliably stop this drift? Link to comment Share on other sites More sharing options...
ronin Posted March 6, 2017 Share Posted March 6, 2017 I presume that you are referring to some sort of finder ?? If so the normal method is to do it during the day and aim at an object about 2 miles away - any convenient church spires ? When I did mine I was lucky to see a "faulty" street light about 1 1/2 miles away that had not switched off and I used that. Church spires, trees etc don't move a lot, but you want something easily defined so maybe not a tree - too many branches. Any signs on a building at the right distance? You will need around 2 miles to reduce the parallax. If you use a star then yes they drift and the least drift one is Polaris, it transcribes a small circle around the axis. Still drifts but not apparently as much. Link to comment Share on other sites More sharing options...
