Horsehead Nebula with one-meter telescope

Although the one-meter telescope we are working on at the Tzec Maun Foundation is still a long way from performing as it should, it’s still capable of taking some very nice images. We have had a chance over the last week to step away from the work of testing and documenting the current issues, and simply take some great images.

On the plus side, that one meter of aperture grabs a lot of light, so we can get lots of photons in a very short period of time. On the down side, the primary support issues prevent us from getting much better than about 1.5″ FWHM even if the seeing is arc-second or better. We expect to pull the scope apart and reassemble it in about a month to see if we can find the source of the support issue.

This Horsehead image is 55 minutes of exposure time – eleven 5-minute images. Most of the processing was in PixInsight — an average sigma combine, following by a deconvolution (mostly to make up for the optical quality sacrificed to that primary mirror support issue). A little non-linear stretching in Photoshop afterwards, to bring out  details that are similar in brightness.
