So I am returning to the hobby for the first time since I was a teen. Picked up an 8' Dob and needed to collimate after it was shipped to me by another CN member. I chose a laser and it appeared to work fine. However, I was unable to achieve focus on the moon with an EP. Tried collimation again, ultimately same result.
My next step was to purchase a 2nd laser and a Chesire and low and behold, the original laser is definitely off as the 2nd laser and the Chesire give me a matching result and the 1st laser does not. I will return it. I will wait for a clear night to verify I can now achieve focus.
Just a heads up to others who rely on the laser that it is not always accurate and not necessarily the best tool for the job.
On another note, anyone have a good procedure to collimate a laser collimation tool?
