First center Megrez in your view, then shift roughly half a binocular field toward Dubhe (a Ursae Majoris).
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.
Details: 90-mm William Optics Megrez refractor with Canon 40D digital SLR camera.
(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.
M40 is positioned 1.4[degrees] northeast of Delta ([sigma]) Ursae Majoris, also known as Megrez. You shouldn't have too much trouble finding it in 10x50 binoculars, but even my 15x70s don't cleanly separate the 9.7- and 10.1-magnitude component stars - they're just a little too faint and too close for a definite split.
1/1600s, ISO 800, Megrez 72 refractor, 2x Barlow, Canon EOS 550D.
The 90-millimeter f/6.2 Megrez 90 (right) and 132-mm f/7 FLT-132 are available in packages that include a 2-inch star diagonal, 1 1/4-inch eyepiece adapter, mounting rings, and carrying case.
I find that with this route there is quite a jump from Dubhe into 'open space', so I prefer to follow from Megrez to Dubhe, and then onto 23 UMa, north to 24 UMa, and then just track a little west to reach the pair.
Our next object is M40, a double star near Delta ([delta]) Ursae Majoris, or Megrez. M40 was once considered a missing Messier object.
But the Big Dipper has one distinctly dimmer star, 3rd-magnitude Megrez, which connects the Bowl and Handle.
With the right eyepiece, you can get 3.3[degrees] (Megrez 66 APO) to 4.8[degrees] (Mini Borg 60) of true field--something that's simply not possible with longer-focal-length scopes equipped with 1 1/4-inch focusers.
