The diffraction spikes are a simple device to increase the brilliance of a star without making the star a big ugly blob - the star itself remains a tiny pin prick in size this way.<br />Don't forget, this is just a test piece and a sketch of a photo of the Lagoon, and to test the suitability of the titanium oxide to provide that extra lift in brilliance that the soft pastel just is not capable of. But by the same token, this test piece shows how the Mellish Technique can reproduce a photograph. Which is also a great way to become familiar with the technique BEFORE you attempt to do so at the eyepiece. See how the materials respond, how to load the brushes, layering the material in order to correct and also achieve the effect you want, reproducing stars, etc. Something you can do while you are on your journey to retirement! :)<br /><br />Alex.Alexander Masseyhttps://www.blogger.com/profile/18035382776041765272noreply@blogger.comtag:blogger.com,1999:blog-8639131949496782222.post-48413747243083824682016-07-30T08:02:46.330+10:002016-07-30T08:02:46.330+10:00Beautiful work of a stunning nebula. The diffract...Beautiful work of a stunning nebula. The diffraction spikes on the brighter stars are a nice touch. This past new moon I got a look at the Lagoon using an O-III filter for the first time. It brought out amazing detail, and I immediately decided it was a prime candidate for a sketch. Probably won't be until next Summer after I retire, but I'm definitely going to give it a go. I'm still using graphite pencils on white paper and inverting the image in Photoshop, but I'm also considering Mellish on black paperBinocranehttps://www.blogger.com/profile/04817855107504539810noreply@blogger.com
