I took saved these visible light guider images while I was taking a near-infrared spectrum of the supernova with the SpeX instrument on NASA's Infrared Telescope Facility (IRTF). The telescope is set up so that infrared light is directed to the spectrometer while visible light is sent to the guider using a dichroic. This color image is constructed from 10s exposures in SDSS g,r,i,z filters taken over 90 mins. I aligned and stacked them in Python.

The FOV is waaay to tight at f/9.3 on a 3 meter telescope. The whole galaxy is 12 arcmin long! This instrument is meant for precision guiding, not astrophotography, but I figured I'd give it a shot!
