Hi Folks,

Very clear skies allowed me this look at the famous supernova remnant M1, also known as the Crab Nebula, in the constellation Taurus.

I studied the object for about 3 and a half hours over two nights before I made the sketch--apparently being a planetary observer has turned me into a real grind. :)

I used Strathmore 400 series medium 80 lb. paper and a 2B pencil. I adjusted the gamma a little during the scanning process and flipped the sketch digitally to achieve the correct image view.

M1 has a fabulous history and some astonishing facts about its structure. If you're interested you can read more about it in my observing report in the DSO forum.

Micheal, it takes me that long to find it.

You did a great job with the crab, bringing out those every subtle changes in brightness. They are really difficult, as I remember - and don't ever remember seeing much in the crab. The darker protrusion is also well rendered, I've seen that. I bet it held your attention for more than 3 hours. Always fun to spend time with your subject - savoring it. Well done.

Nice work Mike. My 8" view was the same shape but perfectly smooth with some faint field stars mixed in. I'd always wondered what higher magnification would have shown besides severe cropping. My holy Grail sought was those scalloped edges some see that I finally saw through an 18". After Jupiter passes and there's that planetary interim I'm sending my 15 ye old mirror to get recoated with the higher reflectivety and see what pops on spring galaxies.

Enjoyed it Mike and nice variations in the interior.

Really beautiful rendition. Looks like the real one.

Michael, fantastic observation and recording!!!

I've always found the subject of M1 to be filled with brilliant information, both regarding it's observed history through the centuries and the physics data that reveals it's bizarre pulsar characteristics.

That said, I've sadly never spent more than a handful of minutes at the scope, merely to say, "Yup, there it is." You've given me some new inspiration. I'll add this to my short list with Ganymede.

Thanks, Michael.

Michael,

That is a super sketch. With dark skies I have never had as good a view as you captured in that sketch. You really need to stay with these gossamer targets to get out all they present. That said, it is more than twice as difficult to accurately record what you see. And as you record, you see even more.
Wonderful sketching.

I hope to see more of these Michael.

Frank :)

Thank you all for your very kind comments. I think that sketching comets has helped me with my technique on DSO's.

I was hoping to add a high power view of M1 to this thread, but so far the weather has not been on my side.

@Jason--The SEDS webpage on M1 mentions that some people say there are two egaual size groups of professional astronomers--"those who do work related to the Crab nebula and those who don't." :cool:

M1 is hard to sketch, because it is not easy to differentiate the subtle shadings. I very love your sketch, thank you.

Thanks, Tommy. M1 is so ghostly I can well imagine it would be rendered invisible by light pollution. I spent over an hour once with dark skies but under below average transparency conditions looking for it with my 4.25 inch reflector. I knew it had to be in the FOV but I could not detect it.

Uwe, thank you very much. I was fortunate to have good conditions and plenty of aperture. With smaller instruments it has always appeared a smooth gray to me.

Still stymied by the weather as far as adding a high power view (and maybe the pulsar). Clouds rolled in this morning right after the Europa transit and shut me down.

Very nice sketch of M1. I've only seen it with my 4" sct, and it didn't look like that, lol.
