Description

My first attempt to use a Hyperstar lens on the Westport Observatory's 14" EdgeHD scope. It was a lot harder than I anticipated. Moving a camera to the front of the telescope shifts the balance considerably and rules out using a Bahtinov mask. It puts the camera LCD and focusing knob on opposite sides of the scope, the camera itself causes funky diffraction spikes unless you add a physical mask, and then there are SIX separate screws for collimating the Hyperstar. It's not a very practical setup unless it can be left on for several days, altough it sure is nice to get huge data sets in little time with no guiding.

For this image, I added a stack of shorter exposures to avoid blowing out the Trapezium, and then partially color mapped it to a shot from last year.
