Keeping the Sun in the eyepiece

Post by denababy » Wed Jan 31, 2018 12:56 pm

Hi there I have just spent a few hours setting up my eq3-2 tripod and Lunt 50ha, pointing to the North, I have marks on the floor put there one night after getting polar alignment I balanced everything as close as I could then using the hand controller I moved the scope to line it up with the Sun and set the hc to Solar tracking. I charged my battery over night. The reason I did it so very carefully was to try to have the tracking spot on so that when the clouds give us a decent break I can get some good data but sadly, although not a long way off it was off a bit. Anyone advise on how to get perfect tracking.

You will never get perfect tracking but then it is not necessary either. If you are watching by eye then you can make tiny adjustments, if using a camera then sometimes a little drift can help eliminate Newton's Rings :) The amount it moves will not ruin your images as exposure time is so fast anyway. If however you want to take a timelapse and want to go away for 2hrs and leave it running then you would have to use a Hinode Solar guider. But I tend to sit and watch for 2 hrs instead and make micro adjustments (I like staring at the Sun).
