Nice Solar Prominences Today (PST Image)
"David Cash" wrote in message Hi to the group, I thought I'd post an image taken this morning (Saturday May 6th) of some nice solar prominences. The image is he http://www.djcash.demon.co.uk/astro/...ay_06_2006.jpg The image was taken using my new Coronado PST with a Phillips Toucam Pro webcam without a barlow. Two sets of AVI files were used to build the resulting composite image. Each set was exposed differently so that disc and the fainter prominences could be shown. Has anybody else managed to get an image showing these prominences today? I'd be interested in seeing them. You seem to have captured more prominence details than the Catania observatory did in their picture taken just 21 minutes earlier http://web.ct.astro.it/sun/solec.jpg : but it is my general observation that the 40mm aperture PST at 50 x magnification consistently shows more prominences and better details in those prominences than can be seen either on Catania observatory or Kanzelhoehe ( http://www.solobskh.ac.at/docs/latest_frame_en.html ) web-published pictures.

Anthony ( with PST at 30 km east of London ) PST is a great scope and can certainly capture the detail when pushed. It does help having something to practice on though and AR875 has been a great help over the last couple of weeks... http://www.digitalsky.org.uk/solar/ha-20060422.html http://www.digitalsky.org.uk/solar/ha-20060424.html http://www.digitalsky.org.uk/solar/ha-20060426.html http://www.digitalsky.org.uk/solar/ha-20060429.html http://www.digitalsky.org.uk/solar/ha-20060501.html http://www.digitalsky.org.uk/solar/ha-20060503.html -- Pete http://www.digitalsky.org.uk |

wrote: Hi Pete, I've been looking at your PST images over the last few weeks and decided to get PST to see if I could get images as good as yours. I agree that the PST is capable of some good images, however as is usual in astronomy it's the local atmospheric seeing conditions and turbulence that ultimately limit was is achievable at any location. http://www.digitalsky.org.uk/solar/ha-20060422.html http://www.digitalsky.org.uk/solar/ha-20060424.html http://www.digitalsky.org.uk/solar/ha-20060426.html http://www.digitalsky.org.uk/solar/ha-20060429.html http://www.digitalsky.org.uk/solar/ha-20060501.html http://www.digitalsky.org.uk/solar/ha-20060503.html Hi David, The seeing in Selsey is often good but not *that* good! On occasion, the 5x image was so jumpy that it would almost shift out of the field of view. The big seeing blobs that occur in the afternoon shift large chunks of the image but within the chunks, the detail held together pretty well. I wouldn't say that the seeing was particularly exceptional for any of the captures I took. A lot were taken while dodging cloud and the seeing around the edge of clouds is often very poor. -- Pete http://www.digitalsky.org.uk |
