Here is my capture of M18/NGC1907.I sketched this on Saturday.The weather was cold with a slight haze over the sky.I was just trying out a new eyepiece when I decided to have a look at M37,In the 20mm Nagler the view was awesome.I then went on to M36.I didn't find this OC that interesting.So on to M38.I found M38 mildly interesting until I saw a faint cluster in the outer reaches of the 13 Ethos.I identified it as NGC 1907.I fount the view quiet intriguing with the 100 Deg field of view.So I put it to paper and here it is.

A 2 for 1, can't beat that, I guess that's what an Ethos does for you! Great sketch, thanks for sharing. Love the way you captured the faint glow of light from the clusters themselves.

I like the nice range of star dot sizes. They really bring the drawing to life because the stars here do vary a fair bit in brightness. Another neat touch is the opposing gradients in the field of view and the surrounding 'frame.' Was this intentional, or an accident of scanning?

John,

An excellent observation of M38 and NGC 1907. It must have been quite a view through the 13mm Ethos! Thank you for sharing it with us all.

That's funny, I sketched M38 on the same night than you! But your sketched has the little surplus with NGC 1907.

Thank you all.The light gradient is from taking a photo with the digital camera.I wish it wouldn't do that but I guess it is a neat effect.When I invert the sketch I only invert the circle.

With the 100 deg field of view there is alot of room around the OC ,I noticed NGC 1907 sitting out there on the outer edge of the field.I really like my 13E but it does make it hard to capture the majesty of the field.It really is a large view.this sketch may be technically right but it fails to give you the sense of the field.

John,

This sketch is very good. It is just what you expect to see with this field of view.:waytogo:

Great sketch, John. I agree with others, I like how you captured the varying magnitudes of stars and the soft background glow from unresolved stars in each cluster.

I am new to sketching and had just a couple questions.

What techniques did you use to capture the background glow in each cluster?

Did you use a Paracorr (or other coma corrector)?

I did not use a coma corrector.I used my finger to smudge the soft glow in.Then I added the stars over it.I then took some of the nebulous stars away with an eraser to get that uneven look that I was seeing.I then cleaned it up in my editing software.

John,

Very well done! I like the effect of your uneven look. Just a tremendous sketch overall. Thanks for sharing it as it is probably the only way I am going to see anything until next week. Snow and clouds.
