Triangulum Galaxy

M33 - Triangulum

This was an awesome collaboration between Drew Evans, Jeffrey Horne and me. Drew used his Celestron RASA 11” with a ZWO ASI1600mm-pro, and a Baader High Speed Ha filter for the narrowband to capture 43x600 second exposed images. Jeffrey used his Celestron RASA 8” with a ZWO ASI2600mc-pro, and an Optolong L-Pro filter to capture 48x300 second exposed images. I used my Celestron 9.25” EdgeHD with a Starizona Hyperstar with a ZWO ASI2600mc-pro without any filters, as the camera has an IR cut window, to capture 50x180 second exposed images. I used Pixinsight to combine the images together. Drew’s obviously as the Hydrogen Alpha channel, Jeffrey’s as the Luminance Channel, and my image as the RGB. All post processing was continued in Pixinsight.

Triangulum, Messier 33, is a spiral galaxy approximately 2.73 million light years away in the constellation Triangulum. It is amazing to see all the nebulas and star forming regions.

Drew and Jeffrey are both experienced imagers who work for OPT Telescopes. They bring a great deal of personal astrophotography experience to a great company.
