Monoceros from the Window-sill – – -29/11/2017

Here’s a couple of the items we discussed at the last RAG meeting.

Hubble’s variable nebula, NGC2261 or C46, is only 2′ in size and therefore not really suited to the window-sill ST80. Will have a go with the SCT next time I go outside.

 

 

As a seasonal image, here is NGC2264, the Christmas tree cluster. I have turned it the right way up for anyone not familiar with it. It is a bit bigger than last-year’s version!

The star at the base of the “tree” is 15, or S, Monocerotis. The blue “halo” around it is not an entirely optical effect, as to quote Alan Macrobert in his book “Star-hopping for Back-Yard Astronomers”, it is “about as blue a star as you’ll ever see”.
