Highlights 2006

Shown below are some of my favourite CCD images from 2005.  They are taken using a ST-7E camera through an 8" LX200

Stars

Barnard's Star, HIP 87937  (Ophiuchus)  a nearby star with large proper motion,  only 5.94 light years from Solar System

CCD Image (Mag Limit +15) 3 x 60s (median combine), clear filter 2005-05-13  22:49 h UT (#86127-30)

WDS GRB 34 (Andromeda) Red dwarf binary system, located 11.7 light years from the Sun.   Brightest star is mag +8.1 with companion star of mag +10.9 Separation measured as 35 arc secs at PA 65 deg GRB 34 has a proper motion of 2.89 arc secs/year

CCD Colour Image  Approximate Colour Red 1 min (R filter), Green 1 min (V filter), Blue 1 min (B filter) 2005-09-18 20:49h UT (#94008-12)

RR Lyrae - Variable Star.  An alternating sequence of  V Filter (10s exposure) and B Filter (20s exposure) images were recorded over a 5.7  hour interval on 2005-10-13 / 2005-10-14.  Image capture was via automated scripts, however occasional manual intervention was required to keep both RR Lryae and the reference star within field of view and on 4 occasions to remove dew which had formed on the front lens of the LX200 scope.  The dataset records the rapid brightening of RR Lyrae over a 1.5 - 2 hour interval, followed by a gradual dimming as the star proceeded through its regular period. The timing of the rise recorded in this session and during the previous session (S98) seem to be consistent with the standard period of 0.56686776 days.
