<div>Nick/Peter/Martin,</div><div>I could see it from Tarbatness tonight with 10x50s quite easily.Next to a bright star. A diffuse coma was all I could see. Imaging is still not possible until reaches a higher altitude my telscopes are still seeing the edge if the shutter during exposures. Another few days and I will get on to it in claer skies.</div><div>Denis<br></div><div><br></div>
