General Comments: The Horsehead Nebua (IC 4340) and the Flame Nebula (NGC 2024) wrap themselves around the bright star Alnitak (the easternmost star in the Belt of Orion. It is the subject of this First Light shot taken at the f/1.9 wide-field focus of my Celestron EdgeHD 14″ with Hyperstar lens mounted at the upper end of the scope.
Technical: LGRB 15sec/15s/15s/15s times 10 = 10 minutes total exposure. I am more than pleased with the results of this “first light” image. However the photograph is not without problems. You will see in one of the blue shots taken with a blue filter the artifact that multiplied over 10 images left a blue haze below the horse’s head. This has been caused by the large amount of blue light emitted by Alnitak and somehow bouncing off the optics to create the ghost like images.
Additionally there is an almost meteor like streak in the center of the image that was caused by the extension of the diffraction spike from the bright star Alnitak.
