What kind of star was the Supernova in M1 the Crab nebulae?

[remcot]

Was it a red giant or supergiant? And is the neutronstar visible with a good backyard telescope? And what was the brightness of the supernova at its maximum?<br /><br />Can you help me with this questions?<br /><br />Thank you

From:<br />http://www.seds.org/messier/snr.html<br />"The Crab Nebula M1 is the only Messier SNR, the remnant of the supernova of 1054 (very probably of Type II), one of few historical supernovae observed in our Milky Way galaxy. However, other supernovae have appeared in Messier galaxies (see our table), and produced SNRs. These special kind of nebulae can be observed in some cases, e.g. the remnant of the Supernova 1993J in M81."<br /><br />Check this it will answer your questions<br />From:<br />http://www.seds.org/messier/m/m001.html<br />Supernova Remnant M1 (NGC 1952) in Taurus

Is it theoretical possible to get close to a neutronstar? Or is that dangerous.

Theoretically almost everything is possible however neutron stars are not recreation areas for sure. Although you may have several types, they all represent some form of danger. To start and in common they all possess a very strong gravity field (we are taking about stars with 1.35 to 2.1 times the mass of the sun but with just 10 to 20km diameter). Then you may have x-ray bursts, strong magnetic fields, gamma ray bursts, well radiation of the worst kind. <br /><br />So you do not want to be close to one of them.

As for the supernovae brightness check this website and see the video animation.<br /><br />Notice the brightness of one single supernovae in relation to the galaxy and all the other stars:<br /><br />http://www-supernova.lbl.gov/public/figures/snvideo.html
