Twice this week I decided to get up after midnight to add to my list of Herschel 400's. It was 0230 this morning seeing and transp excellent and dark sky meter app registered 19.8. Humidity 58% (good for Hawaii) and temp 52*

 

My first object was NGC 4485 which at the time I didnt realize was the Cocoon (4490) until after the sketch. Its a pretty outstanding pair of galaxies that I have observed and sketched before and I knew it looked familiar! Tonight I could see the mottling within 4490 and the curl at the northern tip. Finding it is an easy hop from Chara in Canes Venatici. Through the finder scope it would remind me of something wonderful at the end of a magic wand made by Cor Coroli and Chara. 

 

Thanks for looking,

 

Cindy

Quite nice!

 

The sky conditions though could not have been perfect, as Chara was rather distorted, correct? Or was that due to its position at the very edge of your FOV?

Thanks Martin,

 

Good point, I didnt actually look at Chara directly in the center, but only at the edge, so I cant speak to this. I also blur brighter stars for a realistic view, and I did do this here without thinking about it in truth. I appreciate the comment, it helps me to become a better observer and record information more faithfully.

Cindy,

 

Excellent sketch here.

This is such a nice pair of galaxies. 

These are visible from the Chicago suburbs;

a tough place to view galaxies.

 

 

Frank :)

Thanks for your comments ZL and Frank,

 

Frank, I am glad to hear its clearly visible from the Chicago suburbs and bet its a beauty from Arizona and without the cold.

Beautiful sketch Cindy, thank you. Looking at the sketches here has inspired me to give it a try myself. That is, if the skies ever clear in my little corner of the world.

Thank you Cindy and I'm looking forward to seeing more of yours. I've been reading the tutorials to get some idea of where to start. Clear and steady skies.

Bob,

 

There is certainly a wealth of knowledge here on CN sketching forum as well as supportive people.

Well Chara here is cropped by the field stop edge. There's no distortion evident.

Hi All,

 

In a rather good sky (SQM 21.4, NELM 6.5+), a lot of details can be analysed with a 25" scope, and Ethos 8mm x390

The structure of NGC 4490 (the largest) appear well, so that several regions HII limit NE halo (D / E / F), and a strengthening of the tip NW ©.

The structure of NGC 4485 is less contrast. Two regions HII in SW limit halo (A / B)

Two of the three small galaxies behind NGC 4485 plan have been seen: VI1 (seen 100% of the time) G1, G2 is difficult, VI3 (50%), G3 has not been seen.

More report at http://www.deepsky-d...4490/dsdlang/fr

 

Clear skies

Thanks for your comments Tom, Pete, and Norme

 

Bertrand, thank you for adding your detailed sketch and information. with the 25”, a magnificent view recorded with the 25” and far more to it than I was aware.
