M38 is a beautiful open cluster of approximately 100 member stars that forms almost an obtuse isosceles triangle with Elnath and Theta Aurigae. It was only after sketching this beauty that I noticed an “X” asterism within it. Turning my sketch upside down, the “cross” was very evident with a pair of stars in each arm of the cross.

I opted to use my 100 degree apparent field of view 13mm Ethos for this observation specifically so that I could include NGC1907 in the same field of view as its northern companion, M38. At 105x magnification, this small compact open cluster resembles a stellar lenticular galaxy set in the middle and slightly south of stars HIP25476 (giant at 6.5m) and HIP25733 (variable multiple star at 6.75m). There are close to 30 9th to 12th magnitude stars within it, but I could only plot around 10 within the hazy backdrop of this cluster at 105x magnification using the 6-inch RC. With more aperture and a small increase in magnification, an observer will be able to pick out close to 30 stars and star chains within this object.

Erika,

Beautiful sketch and interesting side notes. There is nothing quite like a wide field in a premium eyepiece.

Frank :)

Erika, this sketch is amazingly detailed! How much time do you have to spend at the eyepiece to position all those stars?

I once sketched M45 and nearly got flooded with despair to get merely a dozen stars at their places. :crazyeyes:

All I have to say is :bow:

Thank you, Frank and Jean.

Jean, star fields are a bear! It took me about 2 hours. I placed the brightest stars in the sketch and then alternating the pencils and felt pen, started working in small sections to fill in the stars. I began with ngc1907 and ended with m38. I kept telling myself, "just a little more, keep going!" :lol:

It helped that I was using a Gem instead of my Dob. It's nice to have tracking for rich star fields.

It took me about 2 hours


2 hours!!! Wow I call that dedication and passion, Erika! I admire that. I will have to improve my method of sketching to reach 1/10 of what you realized. I will work hard for that, but looking at the results it will be worth every single star that I will put on paper!

Thanks for posting!

Jean

Nice one, lots of detail. I can see why it took so long. Great.

really nice drawing!
I especially like how you render the stars. Very realistic.
