ASTRONOMICAL LEAGUES DOUBLE STAR LIST through my 60mm refractor
I'm embarked in a journey through the AL Double Star List using my 60mm F=700mm refractor.
The recently finished 1.5 inch pipe-mount and the home-made clam shell are of great help.
To find the double stars I follow the instructions written by Bill Steen ,fellow of the ''60mmtelescopeclub''.
I'm already in the second half of this well known observational program.
Last night night,on Tuesday 18-th of February I observed ,meaning find and split the following stars:
Kappa Puppis
Alpha Leonis
Gamma Leonis
54 Leonis
The highest magnification used was 78x ,obtained with a 9mm Vixen Orthoscopic ocular.
An 1.25 inch ''Teleskop Service'' diagonal was used for better ergonomics ,my ex-military 8x30mm IOR binocular for scouting the sky and the ''Pocket Sky Atlas'' for detailed maps.
Gamma Leonis or Algieba is a gem,split at 78x / 9mm Vixen orthoscopic but seen as two kissing spheres at 32 x /home-made 22 mm Ramsden ,nicknamed ''Aristotel''.
