Multi-task­ing cam­era

Sky at Night Magazine - - FIRST SIGHT -

In ad­di­tion to its ca­pa­ble per­for­mance as a guid­ing in­stru­ment, the colour CMOS cam­era that comes with the kit can also op­er­ate as a lu­nar, plan­e­tary or even deep-sky cam­era. Us­ing a back­lit, Sony IMX290 sen­sor with a high res­o­lu­tion, 2.1 megapix­els (1,936x1,096 pixel) ar­ray, the cam­era can record video at 15fps, for lu­nar and plan­e­tary imag­ing, or in­di­vid­ual ex­po­sures up to 16 min­utes long. It fits di­rectly into a stan­dard 1.25-inch eye­piece holder and in­cludes a C-Mount ex­ten­sion tube. To test the cam­era as a stand­alone in­stru­ment, we trans­ferred it to an 11-inch SCT tele­scope and pointed it to­wards the Moon. Al­though high in the sky, the pleas­ing de­tailed on some fea­tures, in­clud­ing Val­lis Alpes. Drop­ping down to the Trapez­ium re­gion in Orion, we were treated to a rich, colour­ful view of the ne­bula sur­round­ing the star group, in­di­cat­ing that the cam­era is sen­si­tive to both hy­dro­gen (red) and oxy­gen (green/blue) wave­lengths.
