back to deep sky :)

Post by yobbo89 »


It was a nice year for the planets, i did a reasonable job ,wished for more but that will do this year, the jupiter animation was fun and my winjupos derotation worked good for me .

pulled out the secondary, gave it a clean, alighned the focuser to the tube with my laser, made a permanent mark on the otherside of the tube for focuser alighnment .. , aligned my secondary with my "cheshire" , i shifted the whole secondary down 5 mm, making sure that the secondary is in the right place and reducing of axis error .. followed through with the laser for the primary, did a star test it was ok, usualy you will see some slight star offset with a f4 between inwards and outwards focus, in some cases the cheshire and laser collimator can work out well compaired to a star test collimation on a fast scope ..

and now onto an ambitious approach .. 6 panel m42 :) .. it's raining tomorrow night :(
