I heard that this object is extremely hard to observe (in visual, of course). That’s why i decided to try 🙂 I bought TS H-Beta filter which is essential during observations of this faint object.
And I can say, with this filter, nebula is quite easy and obvious to observe. It looks like delicate fog.
But you need rich-field telescope to catch it fully in one FOV – to be precise, minimum 3,5 degree of FOV is necessary. And of course H-beta filter, because without it you will see nothing.
Three nights in a row clear sky, it doesn’t happen a lot in cloudy Belgium. I guess I was just lucky. Nice to see the changing shadows and libration. I hope you like it too.

Spectacular view of the supernova in M82 on the night of January 25, 2014
Scketch made at La Hita´s Observatory in La Puebla de Almoradiel, Toledo (Spain).
22:18 UT
With graphite on white paper, looking through TEDI telescope (770 mm, f3.2 ) eyepiece 13mm and the red light of my torch (I call it “the demon” by its two red eyes).
The sky was really clear and pristine, relative humidity 80%. (4.5ºC)
Close to new Moon. My estimate Mag with reference stars is 10.5
I send a sketch of the great supernova in the galaxy M.82.
I could not detect any color in this SN, it looked white to me!
I also observed the SN in M.81 in 1993 (ASOD-gallery).
My sketch here is made with colorcrayons on black paper.
Location: Trondheim, Norway. Info on my sketch.
