A low-cost voice and astrophotography

Min-EQ is a bit 'expensive' table "in WIH German equatorial mount that allows the addition of the Orion EQ-1M Electronic Drive System for long-exposure photos of stars without the" Train "(an effect rotation of the Earth, causing photographic images of the star in time, so do not appear as points of light is visible, but) of circular lines. The framework is particularly suited for the home astrophotography with wide angle. Please ask for more information on astrophotography, see the Astrophotography for the Amateur Michael, A. Covington.

Min-EQ is constructed of all metals (not included), the buttons and is quite robust. The base is equipped with three metal screws in his legs Stuby, though the device is in a position at the top of every stable tripod camera mounting screw with a 3 / 8 (eg, spreadsheets) are. Although very small, the device is also very difficult, especially with the counterweight expected, but it is very portable. It also includes a 1/4-20 adapter for your camera directly to the saddle-MIN-EQ.

The main disadvatage MIN EQ (the difficulty of approximating the polar mountain, which shows the mountain in the right direction for this has the effect of the rotation of the Earth could be compensated). Following the instructions and create the proper setting width and mount point in the direction of Polaris, you can get 5 minutes in length and wide angle (28mm lens) for exposures of stars before losing. I finished the installation of a scope in the Finder MIN EQ units to better align polar and offers a maximum of 15 minutes of exposure to a wide angle of reach. If you have a telescope, you should be able to do what is good or better alignment of the drift "of the mountain.

Another disadvantage of the device is to allow the movement of resistance, the weight of the plot in the crankcase of the engine propulsion. This is easily circumvented by a camera instead of the ball head assembly from the camera to Min-EQ.

In general, I would like the Min-EQ for any one looking to recommend that interested in astrophotography cheap, but with the caveat that large amount of patience to install and use. I advise you to read some good information on amateur astrophotography Covington, but before you buy.
