Category: Multiple star.
Class: NA
Constellation: Canis Major
Data: mag   size 
Position: RA 06h:56.6'  DEC -22*:39'
Description:

The 8.0 mag primary had a nice subtle yellow colour, the secondary, mag 9.0, didn't 
show but the slightest hint of blue. 

That's it for last night, too bad the seeing wasn't more favourable because I had
planned on trying out some of the tighter doubles in CMaj. When I took a look at
Rigel, before I started this session, and found the image undulating frequently 
with no sign of the companion, I knew I'd be limited to low powers. All the above
observations were made with a 35mm Panoptic...I like this ocular!

Best regards,
Bill Becker
