Jim, sorry, I can't criticize this excellent rendering of lovely M42. You've done a wonderful job capturing the wing extensions and overall feel of this beautiful object. And did you also put M43 in there  ?

Good Seeing!

Jim,
I agree that you have done a very nice job in rendering this famous nebula in Orion. You have rendered the tapezium and extensions nicely. Thank you for sharing it with us all.

Wonderful first sketch of M42 Jim, is this a pencil sketch or was it done using a graphics program? Great job! And welcome to CN and the Sketching Forum.

Excellent sketch! 
I like the way you captured subtle changes in nebulosity brightness. Please, write something about your technique.
PS. I would definitely like to see your sketch in greater resolution and a little less compressed jpg.

Thanks very much for the kind words and encouragement!
It was done with a #2 pencil and some klenex wadded up for blending.It was scanned,contrast had to be greatly increased . I did clean up stars(couldnt draw nice circles under the faint red flashlight glow).I used a blending tool to smooth out the nebulosity. I was really trying to be more fathfull to what I saw and not my artistic skills. I then painted over my scribled notes and typed the info in. Image was then reversed.
I cheated on M43 a little, I could detect nebulosity,but only when tapping on the UTA,So I included just a little bit of it.

 CHEATER!!!!!!!
Just kiddin' with ya'.
I don't consider that "cheating" in the least as that is a well-known and very common technique used by many of us; and it is pretty much understood that at times this is the only was to "see" some of the fainter nuances of many DSO's...especially nebula & galaxies.
Some may call it cheating...I call it good observational skills.

Jim,
That's really outstanding work. I wish my first sketch had been one-tenth as good.
I'm looking forward to your future sketches!

Well, it's a very nice job! I realy like to observ M42, speciali the six stars of the trapezium. But it's a so complex sketch, that i dindn't had the courage to draw it yet.
Congratulations

Hi Jim, it's great to have you join in here on the sketching forum. Beautiful rendering of M42 and M43.
Thanks for sharing your technique with us. I think it's a wonderful sketch and the only thing I guess I would suggest is to be careful when you clean up your sketch digitally because it can leave a "residue". On my monitor, you can see pixelated areas around the stars and other areas that you must have cleaned up.
When I have areas that need to be cleaned up, I find it almost better to use a clone tool so that the blend is better with the background. When I try to use a brush tool, the background is never matched perfectly.
I hope that helps a little. But like I said, other than that, there's not much I could add as constructive criticism. It's a wonderful job done, indeed!
And like Wade said, it's not cheating to bump the scope to see more detail. Our eyes can see contrast in movement and when I view something very faint, I slightly move the scope back and forth so I can see it better. I do this for not only solar viewing but for DSO's as well.

Now THAT surprises me!!!!!
Not that you jiggle or move the scope to see finer details, but I would have NEVER imagined that any detail on the sun would be subtle enought to have to use this technique.
See...this is a great site and forum for learning new things every day.

Jim, that is an excellent illustration of M42/M43!
I noticed the tiny artifacts around some of your stars that Erika mentioned. I think that may actually be related to the level of JPG compression you are using. Sometimes higher compression can cause subtle, pixelly* donuts around stars. Those tend to show up on some monitors more obviously than on others.
Keep up the great work!

Come to think of it, it is indeed around all the really bright areas of the sketch, even around the typed info. Why doesn't it do it around the nebulosity too? Is there a way around it?
Wade, yes, features can be lost in white light viewing because of the brightness. And in H-alpha the same is due to the darkness, especially the faintest whisps of prominences. Continually making slight adjustments to the Etalons in h-alpha viewing will draw out hidden features as well. At first glance through a PST, you only see the most remarkable features. Having patience, adjusting the tuner and moving the scope slightly back and forth brings out a wealth of more detail.
