I had brought my standard eclipse equipment which consists of a Canon EOS-550D camera and a Megrez
72 refractor which I use with a *2 Barlow.
The seven stars of the Big Dipper are known by a variety of names including the traditional set Dubhe, Merak, Phecda, Megrez
, Alioth, Mizar, and Alkaid.
Province Star in Big Dipper Yong Kui shu "Chief" "Pivot" Dubhe Ji Xuan "Whorl; Rotator" Merak Qing, Yan Ji "Axis; Armillary" Phecda Yang, Xu Quan "Balance; Scales" Megrez
Jing Heng "Balance arm" Alioth Liang Kaiyang "Yang initiator" Mizar Yu Yaoguang "Twinkling Benetnash brilliance"
The main image was taken with a Megrez
72 fitted with SXV-H9 CCD on March 18 at 21:22UT (5x120s exposure) while the inset image, which clearly shows the supernova, was taken with a Celestron C11 and ST9XE CCD combination at 21:18UT (10x60s exposure).
The visit was captured by BAA members Nick James and Peter Hudson and Nick's image, photographed from his observatory in Chelmsford, Essex using a Megrez
72 refractor and Canon EOS 10D camera is shown here.
b) A tracking equatorial mount with a Canon 500D camera attached to a Megrez
72mm apochromatic refractor with a x2 converter for a total focal length around 900mm.
1) My main objective was to obtain a high quality, high definition video of the event using a Megrez
72 telescope and a Canon EOS 550D DSLR working in 1920x1080 video mode at 25 frames per second.
