Description

M33 The Triangulum Galaxy

This is a high resolution image of M33 taken using a 16803 chip and a 12.5" RCOS carbon fiber tube astrograph with Astro-Sital mirrors, a field flattener and AstroDon filters.

Guiding was done using an Astrodon MMOAG and an SBIG ST-i camera.

The seeing conditions while shotting the limuniace frames averaged 1.25FWHM and about 1.6FWHM while obtaining the chrominance data. The resolution os 0.65"/px.

My skies are dark and average 21.7 on my SQM meter when there is a new moon.

Although I don't have a lot of data on this object and the data collected was done so during a camera thermal test, I think the image is not to shabby.

Thank you for looking.

Dave
