A Sketch of Messier 17 The Swan and Messier 16 The Eagle Nebula (updated)

Here is a copy of Messier 17 that I did, the Swan Nebula out at Vernon, Utah.  It was done at high magnification, using a 10mm, 7mm and a 5mm Pentax XW.  I also barlowed the 7mm but the view wasn't great.  Best views were at 7mm and 5mm (the 10mm was nice, but not as large).  Done the week of July 17th, 2012. I did round a few stars out on this after getting back from the field.  Antoniadi was I to II on those nights when I sketched.  I focused mainly on the Swan and not on the area underneath the Swan.  Overall I am very happy with how it came out.  I was considering submitting it to Astronomy Sketch of the Day but they ran a Swan Sketch that I also really liked on July 4th, 2012, see this link.  So to avoid being redundant I didn't submit it.





Before my back was out too bad I did make another sketch of Messier 17 from my backyard and once my house is back together from the carpet and floor install, I'll process that and put it on here to contrast views from a dark zone (gray to black) to an orange zone which is light polluted for me.  I have mixed feelings about this month's new moon phase. It will be the last one I have before going back to teaching and school full time.  That cuts into my viewing time which is okay, because I have a life away from astronomy, it just means I have to hope for clear skies when I can get out! We've had an active monsoon this year and I am hoping that by mid August it lessens or moves east.  It's been good for the yard and garden though (and the weeds)!

As promised, I actually got two sketches process, one is Messier 17 The Swan under light pollution.  That is the first one.  In comparing the light pollution version vs the dark sky one you will see that the dark sky version has more stars visible, has more structure detail visible and the surrounding halo is visible in the sketch.  The light pollution one lacks detail and the distinctions that are in the dark sky one above.  There is some definition, but not much and I had to work for the definition I saw.  This was done on July 27th, 2012 at around 11:00pm MDT in Herriman, Utah with an Antoniadi III sky using my 14 inch dob with a 7mm Pentax XW and a 5mm.  I also had to use my Orion Ultrablock NB filter and my OIII filter.  Please remember that on both sketches these were initially upside down, much like Jeremy Perez capture but I re-oriented them so they would be more easily viewed.





Lastly, here is my version of Messier 16, the Eagle Nebula.  The fingers of creation are evident as is most of the nebula.  For some reason my camera cut off the top part of the sketch and I may later take a new one to include that but for now this one will have to do.  Overall I am very happy with it.  It was done the week of July 17th, 2012 at Forest Road 006 Site 1 with Antoniadi I and using my 14 inch dob with a 10mm and 7mm and 14mm Pentax XW with a Type 1 2008 Paracorr (laser etched emblem).  I used no filter, and an OIII and Orion Narrowband Ultrablock filter.

    Very nice Jay! The "swan" is one of my favorite summer objects.
