Declination setting circles
All,
On my rather (read: very) cheap equatorial mount the declination setting circle tends to move with the scope - this can be a pain when trying to hold a flash light in the mouth, hold the setting circle still with a finger and move the scope to the degree and minute. Adjusting the nut on top of the mount does not help. Is there any reason to not just glue the setting circle to the mount at the required 90 degrees directly in front? Thanks, Kirby Benson Las Cruces, NM |

There's no reason why that Dec setting circle shouldn't be fixed, and I don't think it's supposed to be. Take care you do it at the exact location ( e.g. do a very -very precise polar alignment) before setting it to 90 and fixing it. -- CeeBee Uxbridge: "By God, sir, I've lost my leg!"
