M13, a first for me!

Observation of September 7, 2019 at Cap Ferret. EAA observation with SiOnyx Aurora night cam, afocal mount on Dobson 400, good seeing and transparency conditions to zenith. Original drawing on black Canson A3 format with dry pastels. Formatting with photoshop. A total of 8 hours of drawing!

 

Clear sky,

Francis

Spectacular. The same view I get visually with a 9.25" SCT under very good skies. Your sketch looks like a photo. Thanks for posting.

Francis,

 

Very carefully drawn sketch of M 13. I can tell you worked faithfully to the eyepiece view.

 

Well done.

 

Frank :)

That is an awesome sketch! I like the way you got those Octopus arms that I always seem to see in my 10" Dob. With a 16" that must be awesome! Bordeaux......cheers!

Looks very nice, especially for a first! Do you still see the propeller with EAA observation?

Feels like I’m looking through my 8 inch dob a few nights ago with a 12.5 Morpheus EP, nicely done!

No, I didn't. In fact, I have used a 25 mm Celestron eyepiece for that specific sketching/observation in front of the SiOnyx Aurora cam, I could n't detect it. But it was possible to see it with larger magnifications, for example using a 9mm Nagler or a 5mm Pentax eyepieces.

 

Clear skies,

Francis

I take a picture of the sketch and I draw with help of photoshop a black circle arround it order to simulate an eyepiece atmosphere. I also use the curves to balance the contrasts of the picture.

 

Clear skies,

Francis

Francis, its fascinating when someone can render a globular to look like an eyepiece view, bravo!
