This supernova remnant lies in the constellation of Taurus the Bull and is often overlooked.
I took this image using my 80mm, f/6.3 refractor, a Vixen Atlux mount, PHD auto-guiding, an Atik 383L mono CCD camera and a set of Astronomic narrowband filters, H-alpha, SII and OIII.
I captured five minue sub frames with matching dark frames and combined them with flat fields to reduce the effect of vignetting in the final image.
The total exposure time were 90 minutes using a H-alpha filter, 60 minutes using an OIII filter, 50 minutes using a SII filter and 15 minutes using a blue filter.
