December Doubles
A clear spell coincided with the rise of the full moon on December 14th. I set the scope up in the shadow of the house and at 6pm before the moon was too high I sent the Meade 127 to Pi Arietis (STF 311). At x76 it made for delightful sight set in an interesting star field. Component B was not split but C was easily visible.
Sketch of pi Arietis by Mike Wood through his Meade 127. To the NW there was an obviously red star; later found to be T Ari. To the east was an obvious diamond shape of 4 stars and just on the edge of the FOV were three stars belonging to the cluster DoDz 1. At x76 Component A appeared white and C had a hint of orange.
The WD Catalogue indicates component D, magnitude 10.5, separation 220", position angle 134° and is referred to as ARN 31. At x158 AB were nicely split, A now looked pale yellow and B had a hint of orange.
