2 Star Alignment Accuracy - Synscan

I would like to know what Stars IIS members are using this month for their 2 Star alignment procedure using the Synscan hand controller ( I assume some people are still using the hand controller not a Laptop with alignment software )



I'm getting various results using Hadar and Acrux early in the evening before they cross the meridian ( between 55 arc sec and 4 arc minutes of error )


I'm using both a 20mm and 12.5mm illuminated reticle eye pieces with and without a 2 x powermate ( the 12.5mm is so difficult to use due the narrow FOV , crossing back and forth from the finderscope to the eye piece)


My HEQ5 mount has a specified pointing accuracy of up to 5 arc minutes, so I assume that if my Star alignment error is below 30 arc sec then my pointing accuracy should be close to 5 arc minutes ?


I welcome any advice , comments and information of your Star selection and / or procedures etc..


Thanks in advance
