Link to full report

I was able to grab two sketches of NGC7635 the other night. One at 75x and the other at 225x with my 16" f/4.5 reflector on a non-driven Dobsonian mount and a Baader Hyperion zoom with an O-III filter. Hopefully the inverted ones will still look ok. Sometimes the contrast on my monitor makes it difficult to tell if others can see it like I do with my screen. I also noticed that I didn't do a good job with the 8th mag star in the middle of the nebula. It should have been bigger. Other than that, I'm pretty happy with the star placements for a change. :)

Sketches created with AL template, #2 graphite pencil, loaded blending stump with charcoal, super-fine Faber-Castell Pitt artist pen ā€œSā€, 0.5mm mechanical pencil. I then inverted them to show what they looked like through the eyepiece with the black background.

Erika,

Very well recorded.
I have not sketched N 7635 or looked at it recently from dark skies but that is about how I remember the filtered view in a similar sized Newtonian. I would guess your Texas location skies are pretty good on transparent moonless nights.

Frank :)

Nice sketch. I have never observed this one. I'll have to try it. Thanks for posting.

I like that you included 2 magnifications.

These DSO were certainly hard to sketch. Placing the stars and their magnitude while observing asks for great observation skills.

You have all my admiration for that. Very nicely done.

Jean
