Yesterday night it was so cold that my telescope froze! Before to go back inside, I obtained some images of Merope (one of the Pleiades). It is the star surrounded by the major part of the nebulosity (look at my previous post). After processing of the final picture I had a surprise: if you look at the star, you can see a small spot attached on the right side of the disc. I thought it was due to a dust grain on the lens, but then, searching on the internet, I discovered that it is a little nebula (IC349) distant only 0.06 light years from Merope!
