Description

Now we got spring and ,of course, we all brush up our gardens.
But I tend to leave such activities to my wife (L.O.L.).

Instead, I brought my telescope to a "old stock, but new..." level, by performing a re- collimation.

And I thought the good old Messier 3 star cluster would do a good job to reveal the result.

cheers
