What to choose
What lenses would be the best to get . Andrews are offering four GS Plossl lenses with the 10" Dob. Which values would give me a good variety. Also I will get the Laser Collimater but Lee Andrews mentioned a Cheshire eyepiece collimater. Is this required in addition to the laser Collimater or is it a cheaper alternative.
Any advice would be appreciated
