Full Solar Disk Mosaic with Scale

Post by rray6 » Thu Mar 13, 2014 7:12 am

It's been a while since I posted but I decided to post a recent full disk mosaic solar shot (Jan 20, 2014) and share something with the group. I often get questions about scale of the sun relative to the earth and other measurements that we can relate to. Recently I found a cool template (Regle Solaire) from French solar imager, Guy Buhry, and added some appropriate English translation. I have attached two images - one without the template and one with it. The original image was taken in four quarter section shots using my Lunt LS80 Ha DSII scope and a Point Grey Grasshopper USB3 camera on an AP1200GTO mount from Redshift Observatory in New Mexico. I used Photoshop CS6 to merge the sections into a mosaic of the full disk. I then took the full disk shot and added the template to it. The template is applied as a second image copied on the original photo and then adjusted using the Free Transform feature in PS. It is not perfect but provides a pretty good approximation of scale. There were some interesting proms that day which I can now put some scale to. Here are links to the full-scale images if you are interested - http://astrob.in/full/83679/B/" onclick="window.open(this.href);return false; (original) and http://astrob.in/full/83680/0/" onclick="window.open(this.href);return false; (with scale).
